Thanks for sharing!

Thats exactly where the one on my Big Bear is located

It sounds like the internals of your muffler may be burnt out and the crack isnt helping, you might try fixing the crack aand see if that helps, but if its that annoying i would opt to replace the muffler.

I would choose power steering may not be the mod you are refering to, but if i ever get another one that would be a must have for me. I also may try an automatic i have always had manual shift.

If they have been sitting for a while i would take the oil line loose at the carb to make sure iit it pumping oil in to the carb, also measure the amount that it is pumping. I think for the first tank or two i would use a light premix also just to get everything lubed up good. I know these systems are fairly reliable but one little fluke and your engine is fried.

There should be 12 v going to the sensor, on the wire that plugs into the sensor, when temp gets hot enough the sensor makes contact and sends 12v to the fan. It definately could be the thermostat, with the radiator cap off get it up to operating temp and see if there is water movement within the radiator if there is the thermostat is working. Im not sure about the diade i havent looked at a wiring diagram.

I figured thr .47 was mm

Not exactly sure what size the holes are but that sounds about right.

Unplug the fan from the wiring harness and run extra wires from the battery and attach to the fan plug.

Looks very well made, should work well.

Nice looking ride!

it does sound like a loose battery connection, seen that happen as you described many times

Thanks for the info , i will check them out

I have only used all balls carb kits, so far working well, most carb kits are so cheap i cant imagine them being high quality and heard good things about the all balls kit.

Sounds like fun, havent been to Mexico in years.

I still use conventional oil in my old worn bikes, i use fully synthetic in my autos, but my expierience with synthetic in older engines is that it seems thinner than dino oil of the same grade and in older worn bikes they tend to use more oil if switched to synthetic. I dont race or really abuse the engines but i have still noticed using more oil if switched to synthetic, i have never really understood the reasoning behind half and half oil and never used it.

Chinese carbs have gotten a bad rep, and thats because people like me get a bad one and complain, but recently i have gotten one that is OK, it does not compare to OEM but most people wouldnt notice it , i do, they are many good ones out there, but the trick is finding them. The best way is from word of mouth from people who has used them, or at least get one that has a company brand. If they go to the trouble of putting their name on it thats a plus. I have always been impressed with the build quality, but the jetting is wrong, wheather it is fuel jets to air jets ratio, im not really sure.

I have had good luck getting them out with carb cleaner, i use Berryman B12 chemtool, a little stronger than most carb cleaners, may have to let them set for a few hrs but generally they will come out without damage.

Just noticed the other link didnt work try this one: https://www.ebay.com/itm/175598402017

Those choke plungers are bad to get stuck in the bore,

I havent searched for them lately i will take a look, yes it was new. Sorry i mispelled it https://www.ebay.com/sch/i.html?_ssn=niche-cycle&store_name=nichecyclesupply&_oac=1&_trksid=p4429486.m3561.l161211

Good point! 👍

I usually use a small hammer to get the races started in and once in the hole get a piece of iron pipe or socket the right diameter to push it to the correct position, you can hear when it gets there the sound will be different. I have used a punch but feel it goes in evenly with something of the right diameter.

Thanks for the info, i will look for that app. I figured they should have one just havent looked for it.

I have a 2000 Big Bear and the new Mikuni i put on definately fixed my running problems, i found a dealer on Ebay, Nikki Cycle, that was selling new Mikunis for 1/3 of the price of an online dealer. I was skeptical to order thinking it may be a fake, but it was a true Mikuni.
