I like to ride in wooded and grassy areas. It takes my mind off the everyday routines and helps me deal with my father's cancer. Also gives me a reason to get involved with forums like this one.

I have a 1987-89 (not sure on the year) Kawasaki bayou 300 that has electrical issues, I have replaced the entire harness with a proven good/used one, new CDI box, and two brand new coils, problem is that it tests no charge at the pickup coil, so I replaced and tested again with a so called good one that had been salvaged out of a blown up 220/250 (not sure which, the left side cover is smaller than my 300) in Missouri. It has a proven good OEM stator. I am trying to avoid buying a new start and pickup coil because it is so expensive so if anyone has a suggestion please let me know.
For those in the Northeast, this weekend is going to be a hot one. This upcoming weekend is the Snow Shoe Rails to Trails Chicken BBQ event which we attend every year. Last year for our Jumping Jack, I made a "Redneck Air conditioner" but I found sticking the hose in the door way got in the way. This year I improved upon it and found a way to have the cold air blow into the front window without cutting or sewing the marine canvas. I didn't want to compromise the canvas in any way so I came up with a way to hold it in place with magnets. Made strips of magnets with duct tape and used clear vinyl to cover the window and attach the duct coming from the air conditioner. I did replace the hose with one that is a bit longer, found it on Ebay since you can't buy vinyl dryer duct hose anymore.
We are ready for the hot weekend of riding and camping, and the hose won't get in our way anymore.

Hello all just recently acquired this atv which as you can see in the pics that it has had an unsheltered life. i did get it running and put some used tires on the front.
It still needs a bit more well needed maintenance, chains tightened and oiled. needs an airbox or air cleaner and other misc items.
Hey guys, new here, but haven't found ANY answer to my specific problem on a Suzuki dedicated ATV forum, so here's to hoping!
I acquired a 95' Quadrunner 250, 4x4, (LT4WD) for practically nothing with no spark. The PO had tossed in a used stator which didn't fix the problem... so I went all routes (though cheaply) to narrow down the initial problem of no spark.
Plug, coil, CDI (caltric) and stator w/pickup (caltric) were purchased and installed. And it RAN, but bogged horribly and would not rev past 1/4 throttle.
I checked fuel flow, vacuum lines, all the normal stuff, no issues. I decided to check the valves and cam... well, there was one problem. The cam was 1mm under the lowest spec in the manual. So, in-came a new cam, Stage 1 Hotcams... also threw in a new set of shindy valves, lapped them, replaced the valve seals, and the timing chain.
Back together again (w/stock airbox and new oiled filter). Now it idles even better, still boggs at 1/4 throttle, but will rev past it if you hold the throttle open for a second. Ahaha... success!
So I was able to ride it above 1/4 throttle once I had momentum... could shift through the gears, all was good as long as I kept it over 1/2 throttle. Took a long enough ride to break in the cam properly at least so I won't have to worry about that.
Now, I start fiddling with the carb. It's clean as a whistle, stock, with stock jets (new replacement Mikuni jets). Same problem.
I start thinking, maybe this is fuel related and the bike is having an issue transitioning from idle jet to main jet... so I LOWER the needle by raising the clip 1 spot. Now it revvs up in neutral with no bog, but it boggs about the same trying to ride it. So I move the needle down again with the clip on the top slot. Better, but still has a bit of bog at 1/4 throttle.
The last bit of advice I got was to ditch the CV carb... so I sprung for a brand new Mikuni VM30-83 round-slide. Bolted it up, blew into the vacuum tube to fill it with fuel (no vacuum port on this one) and she fired right up... but there is still a bit of bog, it's just masked by the fact that I'm not waiting for the vacuum diaphragm to open.
So I feel like each little step brings me closer, but not perfect. I'm now wondering if this is still in-fact a carb tuning issue (I have some jets I can fiddle with and maybe lean-out the idle jet a little.) OR if the cheap-a** Caltric Stator/Pickup is what's causing these issues.
I have a 95' KingQuad with 400 miles on it... like new.. runs like a top... I've tried both the stock QR and the Caltric CDI boxes on it, and it revvs up and runs like a champ.
The only unknowns between the two systems are the carb, and the stator/pickup. My next step in troubleshooting is to rip apart the King Quad and test it's CDI on the Quadrunner... but considering there is no change to how it runs I doubt it will lead to a solution.
HOWEVER... I tried the stock CDI just recently after running the Caltric this whole time, and the bike runs like garbage. Hardly idles, and won't rev up at all. So, that is my one smoking gun telling me that it's either the pickup coil or the stator itself.
Has anyone had a problem even CLOSE to this? I can't image the carb would be causing this many issues, especially going to 2 different ones, both with stock jetting to OEM, and exhibiting the identical symptoms... the only change is when different CDI's are plugged in, or when the needle valve leans out the mixture.
Also, I checked the piston, rings and bore when I had it apart and they're like-new... no scoring, rings are loose, cylinder is still round and has honing marks still int he bore. Stock piston, stock bore size and it has 160psi compression. Battery is brand new, and I've tried 3 different R/R's, none of which change any symptoms, but slightly vary the charging voltage by .2-.5 of a volt depending on which unit. Also tried a new coil which changed nothing.
ANY help would be appreciated. Too much invested to not get it running right.

The Hop-Up: You may be saying to yourself, “that’s a chick bike,” and you’re right. But honestly, it’s so much more than that. It’s one badass bike. http://www.quadmagazine.com/quad/features/article/0,24942,1587044,00.html
Hi all, I try to find this manual in the threads but you have a lot of stock here
Cannot find this particular manual.
I found it for YFM200 but not sure if they are the same.
Thanks if you could help me with that.
Im new here so if I did something wrong, please tell me.
Hey I own stock why Yfz 450 and I'm just looking to slap a turbocharger on it.. I was just wondering if they're pretty compatible with these machines it is the carburetored version Yfz 450. I have all the piping hook ups / kit that's threw HURON SPEED an i also have turbo lined up for it gt 12.. I was just wondering what else I need to make this work? I know i would need to up the Jets and stuff for starter but Is it just that simple or do I need blow off valves and like some time on regulator on it or so forth? Trying get ideal what i would need
This is my first post and I was wondering if there is anyone who can help me solve a problem I have with my Yamaha Kodiak 400 4x4 Fitted with a Mikuni Carburetor . The year of the quad is around 1998, the reason I am not sure of the date is, there wasn't any paperwork and no details on the frame either.
The quad had a bad leak from the carb overflow which indicated that the float needle valve was blocked or passing so I replaced this and put everything back together. The quad ran really well until I took it onto some rough ground to have a ride around, a few hours later the engine started to run really rough as if the engine was flooding. I have removed the carb again and cleaned the needle valve out and the whole of the carb just in case there where any dirt behind it. Engine now runs fine again but fuel has started to run out the carb overflow again.
I have tried everything to try and stop the fuel leaking out the overflow but its still happening. My last thoughts where to adjust the float level and its still happening.
Has anyone got any thoughts on the problem or could suggest whats causing the fuel leaking out the overflow.
Thanks for reading
