Twistedtrik Posted June 15, 2009 Report Share Posted June 15, 2009 So I picked up a K&T built 421 4mil. for next to nothing. Guy needed money quick, got the title and all. Anyways it's an 01 with the above motor. It has V Force reeds, billet cages and adapters, 36mm PWK's, K&N Pods, Aggressive port and polish on stock cylinders and a stock milled head. It starts right up, but won't idle ( I completely went through the carbs and cleaned etc yesterday ) It runs, but seems to be on the fat side. I have 165 mains and 58 pilots right now as that's what it came with. It has the FMF Fatty Gold Series pipes on it but I am going to put my CPI inframes in it so I am just looking for some ideas on getting this shit jetted close.

okbeast Posted June 15, 2009 Report Share Posted June 15, 2009 I'd say 158 or 160 mains, 48 pilot a/s around 2 turns out. What needle do they have? Hell give K&T a call they seem to be somewhat of a tuning god, and if they ported it then they would know. Quote Link to comment Share on other sites More sharing options...
Twistedtrik Posted June 15, 2009 Author Report Share Posted June 15, 2009 I think I will give them a call. Problem is i don't have all of the specifics on the motor, guy I got it from didn't have it built so he's just "relaying" info from the PO. I would like to try it on my own and if that means little by little, that's what I will do. I will take your numbers and give them a shot. Thanks for the help.

Twistedtrik Posted June 16, 2009 Author Report Share Posted June 16, 2009 Tore the top end off yesterday to see what was all in it. I noticed that the compression on 1 side was wayyyy off. Everything checked good until I looked at the reeds. 2 petals on the side giving me issues were almost burned to a crisp. The were stuck open about 1/16th of an inch. Now I just need to order some replacement petals for the V Forces. Quote Link to comment Share on other sites More sharing options...

Twistedtrik Posted June 16, 2009 Author Report Share Posted June 16, 2009 Nah they are still in 1 piece but fried all to hell. Looks like somebody took a torch to 1 set of petals. Quote Link to comment Share on other sites More sharing options...
