acceleration problems

[Howie]

well, i checked for kinked fuel lines. no luck. i ordered a stage 2 jet kit, i'll install that and see what happens. where would i get the needles? im assuming they dont come in the jet kit. also, should i tear into my vaccuum pump...maybe that's acting up? ive heard the diaphragms cause issues from time to time. or should i wait and see what the jet kit does?

The kit comes with needles, but does not come with needle jets (emulsion tubes).  When you disassemble inspect the needle jets with a magnifying glass.  If you see any ovaling of the jet it needs replacement.

well, a jet kit solved my problem. i finally got the courage to tear into my carbs, and im glad i did. i now have a much better understanding of how everything works in there...and my bike is running almost perfect. there is just a little bit of popping once in a while during decelleration, and at idle it seems bump rpm a little...just slightly, only noticable by feeling the rumble. weird, but its running leaps and bounds better than before. i cant belive an exhaust and open  intake would impact the motor that much!

I can't believe an exhaust and open  intake would impact the motor that much!

The exhaust didn't make much difference that I could tell, but changing the intake made a huge difference.

I tried all four combinations of with and without pipes and with and without open airbox and as far as I could tell the pipes only made a difference at higher rpms and full throttle.  The airbox made a difference all over the rev range.

Glad to hear that you have your bike (mostly) sorted out.

Raising needles 1 notch could solve that.

thanks!

yep, even though it was a pita to deal with, fixing the bike was very eye opening and rewarding. i do almost everything myself as far as mechanics go, but i hadnt dealt with carbs much. now i just have to do my first valve adjust this winter....
