Hey my ds runs great on the top and middle and almost everywhere my plugs are a bit lighter tan color but not white for sure...sometimes when i downshift i get a pop and sometimes a boom out of my pipe and sometimes it wants to backfire through the carb i think..... when im going very very very slow its only on the low low end that it does this....it ran great in the winter time when it was cold but now that it warmed up its starting to backfire any ideas the air fuel screw seems to run better the more i turn it out.

 

Im not for sure but it sounds like you need to go up a size on your pilot jet? [img]i/expressions/face-icon-small-confused.gif[/img]

 

yea but it ran perfect last summer.........................and nothing has changed since

 

have you done any mods since?

 

nope my endcap was stripped all the insides last summer i had uni filter last summer everythings the same...my filter is a bit dirty and right now im like 5 turns out on the air fuel screw and if i turn it in more it really pops then

 

Wow! thats weird? Well im not the greatest at carb work, maybe if Hightower sees ths thread he could help. I dont want to give you any wrong tips, somebody will help ya out, sorry![img]i/expressions/face-icon-small-cool.gif[/img]

 

Ive had alot of problems with the stock carb, i just bought a 450r carb. I dont have it done yet though, i just got done putting the jets in it, ive got to modify my throttle cable to work and ill be ready to fire it up. Im hoping its gonna rip![img]i/expressions/face-icon-small-happy.gif[/img]
