Hey everyone-
Just got to the point where I need to tune my carbs. I have switched the stock air box with velocity stacks and am now running straight pipes. I bought a rejet kit from TJ Brutal Customs that came with 3 sizes of Idle jets, and 2 sizes of main jets. I currently have the smallest size of each in the carb, here is what is happening:
Will not idle (shuts off) unless choke is pulled (slightly less than halfway choked gives it a solid idle). Revs like a champ when in neutral with no hesitation at all (choke still partially pulled).
I took her for a ride to see how it went while in gear...Severe performance dropoff at mid-higher RPMS.
My conclusion (this is my first time working on carbs and my experience and knowledge has been limited to my research online)
-needs more fuel at idle, so I need to put in larger size idle jet.
-needs more air at high rpms so the choke needs to be disengaged completely (main jet should be fine at current size)
Anybody able to weigh in on my logic? Any help or info would be awesome! Thanks!
Bike - 2002 VT750 (Spirit) / Dual Carb
I should also mention I have adjusted the air/fuel mixture screws fro m .5-4 turns with no luck on this current jet size setup. Currently 1.5-2 is optimal with choke partially pulled
