Whats up everyone!! Its been quite some time since Ive been on the forums..but Im back lol Few questions. Im running a tm45, and I had to tune this thing myself. I've got it pretty close to being correct, I think, however, I feel like the top end just isnt there. I may be burning a little rich. I'm going to crack the carb open here in a bit and get some new plugs. Let me know what you all think. I'd like to be able to go 90mph~ish. I'm sure I will need to change my stock sprocket ratio, but thats fine. Does anyone think I should take my quad to a quad shop and let them tune it? Last time I had something done, they had no idea what they were doing..and charged me a **** ton. let me know guys!!

 

Basically the bike tops out at around 65? and it seems like most of the power is towards the bottom end...like 2500-4500rpm...little puzzeled. the spark plugs didnt help too much

 

Go to the how to do post here and download the TM manual, it has a good tuning guide in it.

 

Thanks stir im changin it now. I had a 160 main, im at sealevel. and i was running a 50 pilot jet. the needle was on groove #3 from top. going to change everything now and let you know how it worrks. also i dont have the accelerator pump activated, so im going to call ron woods now. thanks again

 

I changed everything. im running a 40 pilot jet with a 160 main and the needle is on the 2nd groove from the top. seems as though it has leaned out. im waiting for my accelerator pump parts
