Tuning a bike is more then just jetting.. its finding the right compression, timing, carbs and pipes, ect.... and making it all work together. There is also "chassis tuning" wich is pretty much the same thing.. Getting all the parts to work their best together.

the only thing i am wondering is carbs you can jet, but everything else is pretty much stuff you buy?

unless i am missing something/

 

thanks for helping me out fouledout.. i have my 421 with shear pipes and 40 m hv lectorns want to get the most out of it,...

you still have to buy the right parts.. then you still have to tune them.. Timing, compression, dome designs. Its finding the right combo with all the parts to find that sweetspot. Some motors like high timing, low compression.. while others are oposite. My motor really liked high compression (195lbs) and high timing (13 degrees on the plate) now this setup isn't going to be optimal for most people.. but it was for me. Your builder can give you a idea of where to start then you gotta take it from there and just keep trying different stuff. I guess thats the best I can describe it.

so where would you guys recommend i start?

 

let me list what i have

 

421 cub

timing is @ 8

40mm hv lectrons converted to alky set up by packard

shearer sm oof

+8 swing arm

12 paddle ultra lites

lock up

override cut by K&t

anything else you guys need to know i will tell you but i am curious to know if you guys think i am doing anything wrong? i am not sure on the compresion i should check that. when i spoke with packard he stated that i would not really gain anything from porting the cubs and to try them out first because i am new to the whole drag setup. he said i should be just over 100 hp and he said at most will be 110hp

i dont know if it is just me but readin this u seem like you are bein kinda vague... but from what i read you are lookin for the best way to set up or tune your bike??? i would say start with are you doing just strict drag racing??? what are you familiar with tuning certain things, if anything, on a banshee??? motor, etc...
