Well I came on here hoping to read a manual about the quad but found that I have to make some posts before that can happen, so here is one.
I work on peoples stuff. Had this well used unit come to me with a no start issue. I found it had fuel and spark was good but it only had 30 pounds of compression. I put each cylinder to TDC and feed the plug hole with a small amount of air pressure and could hear the escaping air coming out the carb openings. I then checked the valves lash at TDC and found that booth cylinders had 0 lash for the intake valves. I reset the lash to .003 for all the intake valves and reapplied a small amount of air pressure and the leaking of air was gone. I then spent a few hours screwing all the parts I had to take off, back together and then drove it out of the shop.
The lash was only 1/4- 1/2 a turn too tight that caused the valve to stay open just enough to make it not start. IMO the heads could use an overhaul some time soon as the valves and seats have become a bit warn.
These ATV's just have too much crap stuffed into a small space, I wounder how many fasteners are used to hold 1 ATV together?
got that 220 I'm 'servicing'.......... well it turned into a guts and oil job.... I cleaned the carb and it wont idle cold, but idles too fast when warm. also misfires and burns rich cold (white smoke out of the exhaust) I'm going to order a new carb since the old one is leaking and beat up (some one was tinkering) I'm wondering about the valve clearance and timing...? Maybe a factor? What should the clearance be on the valves? How should I check the timing on this bike? (this is a mid 90s bayou 220 2x4)
Anyone out there spice up their 2002 Kawasaki Lakota Sport 300 with cam, shaved head, deck the jug, valves?
As you probably have already seen, I have a top end to get built back up and might as well add a little kick to it. Here's a pic of a golf cart I built up recently and modified the engine a little while I had it apart.
Thanks in advance for everyone's help!!

Hello all. I have just stripped down the carb on my YFM225 as it is not running right.
I put it in the ultrasonic cleaner for half an hour and it has done a good job.
Nice clean jets but when I go full throttle it backfires, and there is a lack of power.
It also does not seem to take fuel in properly - it comes out the petcock ok so it is running freely enough, but it is not drawing into the carb.
If anyone has any ideas I would be very grateful.
