It may be the brushes have been reversed, changing the polarity. Have you had them out and accidentally switched them ( and their wiring) when putting them back? If the starter was like that when you got the machine , you could try switching them to see if that fixes it.. I don't know of any other way it would reverse.

Just a small problem. Those bridge rectifiers would not work to rectify and regulate the output of a quad's stator. You would need 3 of them just to rectify the output of the stator. Then you need circuity to smooth those voltage pulses from the 3 phases, and a regulator chip to limit that voltage to between 13.2 to 14.6 to actually charge the battery. There's a lot more circuitry inside that little rectifier/regulator box than you realize.

Your quad likely uses a magneto ignition. Those are killed / turned off by grounding the ignition, If you are looking for continuity when On and no continuity when Off you have it backwards.. When the kill switch is in the run position there should be no continuity through it , and in the kill position there should be continuity. It's just the opposite of a points and condenser or electronic system.

Rod knock is usually, but not always, a duller sound than detonation ping. It is easier to tell in a multi-cylinder vehicle like car than in single or twin cylinder ones in ATVs. A loose rod or wrist pin can knock either under load, when backing off or if fairly bad even when idling but normally detonation only occurs under load. When it is happening in car, it is often described as "marbles" rattling around in the cylinders . Detonation is hard on everything and if not taken care of by backing off the timing advance a bit or by going to higher grade fuel can result in holes hammered or burnt into the pistons.

Detonation is just that. The fuel mixture exploding in the cylinder instead of a rapid (VERY RAPID) burning in the cylinder. It can be caused by ignition too far advanced or by use of fuel too low a grade for the compression ratio / cylinder pressures. When everything is right, the fuel actually burns rapidly as the piston descends on the power stroke. When detonation because of over advance causing cylinder pressure to increase far over normal or fuel grade is too low the fuel instantly burns (detonates) rather than burning continuously during the power stroke. The rattling noises you hear with many diesels when idling are actually mini- detonations with the high compression and very lean diesel mixture.

Heat wave and drought has been brutal with no end in sight yet, but I've been surviving it. At least I haven't had to put in the 2 hours every week bouncing on my riding lawn mower instead of the quad. We haven't had a total of an inch of rain since the beginning of June, and August is normally our driest month, so there likely won't be any mowing needed until next spring. Down side is the bush is so dry and there's so many fires going riding isn't a very good idea. Here's a map of the fire situation in BC now. For perspective, the province of BC is 3.5 times larger than New Zealand.

Knocking noise was most likely detonation from the over advanced condition as Mech mentioned.

Try going directly from the battery to the starter to see if it turns over .. The brushes in the starter could be worn and commutator dirty. They may not making contact all the time. Also check for loose, corroded connections. there might be a break in a wire that is not obvious too. That would allow the broken ends to make and break with movement of the wire during use and movement. To keep batteries from sulphating up when the quad is idle for longer periods, use a battery maintainer.. Sulphate build up from a battery sitting at less than full charge causes the battery to lose capacity until eventually it fails completely or shorts a cell. Sorry I can't help more than giving those suggestions .

Let's get back to the coming election and the possible candidates and choices. This coming one will show whether the extreme right will take over or if the country will start to come back to the middle of the road it began veering away from from the days of Reaganomics.

I am not religious, and I don't force my beliefs on anyone. What religions others choose to follow is none of my business. Your "logic" and "common sense" are sadly lacking.. Yes, evolution determines the path that all life follows but like everything living, there are genetic variations that drive the evolution . Those that are born with the " non-straight" gene normally don't reproduce , although that gene variation still exists. and who,besides you, mentioned anything about frogs? For the most part , it is the religious that are most vocally against the non-binary people.. But you don't have be religious to deny fact when it goes against your belief.

Ulf ,Your rant against gay / lesbians is NOT based on science , but on religion. FACT is there are many examples of same sex paring in the natural world. There are also rare examples of children and animals born with characteristics of both sexes. Your rant against indoctrination of children should include those that try to tell them that to be of anything except "straight" and of the "right" religion is evil and must be condemned goes against both fact and Christ's teachings of acceptance of others.. Trying to indoctrinate children into any lifestyle is wrong. They will develop they way nature intended them to do , whether we like it or not. I am also uncomfortable when others flout their sexuality, no matter what it is . and growing up at a time when those that didn't fit the norm had to hide the fact or face severe discrimination, I am even more uncomfortable when non-straights do it. FACT is what goes on between consenting adults is none of our business. It does not affect us unless they trey to force their views on . Attend whatever church , temple, synagogue, or whatever house of worship you choose. That's your choice , not mine or anyone else's. Religious affiliation is a choice; sexual orientation, just like left handedness, is not and is coded in our genes. whether you want to accept that fact. or not. The same goes for what others do to their body. It affects them, not us. Yes, some tattoos are beautiful, but I'd rather see them on canvas rather than on a body, and piercings totally turn me off, but if they have them but that's their choice , not mine. I am against the pressures that push a woman to choose an abortion for non-medical reasons, but again, that is the woman's choice whether to have one or not. It is NOT ours to make but very personal one of the woman.

The farce is strong in the tRump cult. Jan.6 riots mean nothing ; Illegal posession and hoarding of top secret documents means nothing. Saudi billion dollar deal with tRump's son -in-law and the Saudi's visits to Mar-a-Lag while some of rthose secret documents doesn't hint at anything. tRump's attempts to get Governors to change state voting results mean nothing .. I could go on to fill a page with illegal actions of your cult leader before and after he entered the White House; but all the facts mean nothing. The Democrats are responsible for all the graft , corruption of some of the GOP members of the Congress and Senate. Yup. That' quite the universe you live in . Sure makes me glad to be a Canadian living in the real one. With that I'll let others take up the debate.

You sure live in an alternate universe

The hold the extreme right and the tRump cult have on the GOP is appalling Those polls tell a sad tale of today's America

If it comes to needing drilling for an "easy out" use a left twist drill. Often the bit will spin the bolt out when it bites into it. As mentioned before , use some heat on it and let it cool before using penetrating oil. The heat would kill the locktite if it was used, and by letting it cool before using penetrating oil, you won't end up hardening it so a drill bit won't bite.

I am saying if valves and seats look like that drawing after lapping the idiot that did it should seek other work. "Multi-angle" valve jobs like shown would only be used on extreme performance engines. Normal multi-angle valve jobs are 3 angle; and with more and more manufacturers going to aluminum heads, valve seats are replaceable. Cast iron heads may have induction hardened valve seats but if they are cracked or badly worn and the head is to be kept, they are machined for replaceable seats. If you send your heads out to be serviced, ask the shop if they lap the valves whether the seats are integral or replaceable; and how many angles they use in performance head valve servicing.

I'll leave the reply to the comments you made to the op to others. I don't think the moderators would allow me to say what I think of them and the valve pix you added. LOL...

I'm interested in knowing just for what machine that service manual is. Those pictures show some pretty bad valves, but what I see there , they appear to be more likely the wrong valves used in some applications and in some of them some very serious overlapping. Lapping new or ground valves to an undamaged seat or recut one shouldn't result in wear on the valve of more than a few microns; not enough to remove any hard surface if the valve was only case hardened rather than through hardened. Those pictures do not show valve failures from any proper lapping.

Mike Nixon makes a lot of noise about Neway cutters in his motorcycle babble. I'd listen to the manufacturers and mechanics that recommend valve lapping as a part of a "valve job".. Just the opinion of another that spent his working life in the mechanical trades . Listen to GW and Mech.

Have a safe and very MERRY CHRISTMAS everyone..

You either have an air leak somewhere between the carb and intake port, the mixture settings on the lean side or , most likely, either the high speed needle in the wrong notch or there is a tiny hole in the side of the brass tube the main jet needle slides through. Those tiny holes are often missed when people are cleaning the carbs

A good maintainer will not boil a battery out. They're a far cry from the old ferro-resonant trickle chargers. Flooded batteries are not good in ATVs. They leak because of the bouncing they get from ATV service, and AGM batteries are needlessly expensive. A SLA battery doesn't leak in ATV service and in my opinion is by far the best choice for price and ATV reliability. Yes you can top up a battery every few weeks or at most every 3 to 6 months in storage , but then you must remember to do it, bring them to full charge and then remember to disconnect them from the old trickle chargers. The newer maintainers can be connected and left connected without worrying about boiling them out or having them go flat and sulfate up because you forgot to top them up.

Walmart Canada has batteries that fit most ATVs.. I'm sure they do in the US also. Amazon also lists a range of ATV batteries. Just search on one for your ride. Costco likely does too. Look at the user ratings they list and the number of people who commented and rated to see the average star rating. As I said earlier in the thread, most of the batteries, whether they are a big name brand or a generic perform about the same; and all need to be kept on a maintainer when the ATV is idle for any length of time. Get an SLA battery. . The cheaper flooded ones can leak with the shaking they get from ATV use.. The AGM ones are more for use where they may be mounted in a non-upright position and are needlessly expensive. The SLA are leakproof, and maintenance free beyond keeping them charged up . Beyond that I cannot tell you which battery brand is the "Best" one. You'll find nearly all ATV and utility batteries have a short warranty period compared to automotive ones. The main reasons are the environment they are used in and so many do not keep them charged up when not in use, like the ride -on lawnmower parked and forgotten at the end of the season and expected to start and run next spring for example. Get one well rated by other buyers, and the best price to you, Keep it charged up with a maintainer and you should get years of service out of it. It took a friend of mine several battery replacements before he took the advice to buy a good maintainer for his seasonally used boat battery. Buying one good maintainer is a lot better and cheaper in the long run than buying several batteries because they keep "Failing"

I doubt there is much use fro lithium batteries for starter batteries in vehicles since weight is not really a problem there and lead acid batteries serve the job very well. The LiFePo batteries are seeing increasing use in RVs and other storage applications where large capacity in a smaller, lighter weight package is desirable. The biggest factor limiting their adoption so far is their price. The vehicle fires from lithium batteries were mainly from the earlier lithium ion batteries, not the newer LiFePo ones. I don't know the safety data on the newer ones. Off grid systems pose a lot of different considerations from RV ones. The charge controllers available now for solar/ wind/ micro hydro systems are a lot more reliable and failsafe than those in use a few years ago. They really shouldn't be a determining factor. Initial cost is likely still the biggest determining factor in newer installations although according to the industry the lithium should far outlast the lead acid ones. I don't think there is enough long term data on that count to see if there is any real long term savings to lithium. I do know the short days and weak winter sun along with snow mean systems that rely on solar and wind power need a lot more storage capacity and draw down survivability than in areas where short days and snow are not a factor.-

Dirt is the big enemy of the synthetic lines because of the abrasion it can cause between the fibers of the rope/ tape. I don't know anyone using synthetic lines but there's enough information on them online for anyone who cares to research them before deciding whether it is to their advantage to go that route or not. Randy , be glad you've never experienced the destruction a recoiling cable can cause. The line doesn't have to fail to do it . The point it is attached to is more often the projectile, but the line itself can sever a limb or worse if it catches a victim in recoil. There are enough pictures of what can happen when pulling a stuck vehicle by the hitch ball on the net for example . There's a lot more to winching and vehicle recovery than just hooking a line to something that looks solid and pulling.
