hello.
i have an 88 quadzilla, and i am having some difficulties. The engine is basically stock, it has been gone through, fmf gold pipe, stock reeds, stock carb, k&n clamp on. I have been running a 32:1 mix with 92 octane and suzukis ci two stroke oil. the quad was running really well and i had very few problems, the only thing was it was very loud. I talked to the local shop and they told me to check the silencer, and i did, and there was very little packing, so i repacked it. Now, the thing starts cold just fine, but when it gets up to running temp. and i shut it off and try to restart it takes about 10 -15 kicks at wot before it even fires. Occasionally when I am kicking it, it backfires really loudly. Also, sometime when i am driving it and I pile into a corner too quickly and let off the throttle and then get back on it after downshifting it bogs bigtime. sometimes it dies, and it then take another 10-15 kicks to get it going.
this problem is becoming a pain in the but, and i odn know how to fix it, any suggestions would be great. Is my gas/oil mixture right? what jets should i be runing? help please!!!.

 

try checking the reeds . could be a broken reed . have you changed the plug ? also might be flooding . might also check the float level .

 

i had the same problem this week on my latest zilla after fitting the dg silencer off my other one it ran pretty poorly and when i backed the throttle it wanted to die, i ended up swaping the carb of my other zilla but also noticed that 2 of the reed petals wernt closing properly, i took them off and turned them over and it seems to be fine now,

i noticed that the carb i took of had the air screw right out and im guessing the jetting is to big and the previouse owner has tried to compensating with winding the air screw right out,

in presty sure it had the wrong plug in as well but i aint 100% sure what should be in them,
