once again the only 100% way to tell is doing a plug chop

lol beat me to it... just because i had that big of a gain from my bike dosent mean your going to. i have a realitivly small motor. 4mil with stock bore on fmf fattys... i dought your going to get as big of gain off a 421 but i will say that you will make noticable gains.

get an aftermarket thumb extension. they are like 40 bucks...

its the dyna fs, its the programable dyna... they got them on ebay for 260-285 ish...

almost but not correct... CPI are for top end motors that are looking to drag race... more WOT riding . Toomey T6 are better for unported motors, how ever T5 are best for ported motors that dont drag race much and are more a duner. T5 are the closest to drag pipes for a non drag bike...

anyone got a OEM thumb throttle they want to get rid of?

i use mine to turn on hot sluts that like A.T.M. aint that right Polish lol :beer:

he pulls me when i go to shift cuz i still havent broken my old nasty habit of letting off the gas to pull clutch and shift, where he just pulls and shifts through gears... as soon as i get back on the gas he stopped pulling me.

well man wether you belive it or not it happened i was there as well as polish who after we got done racing he was like wtf did you do? i told him all i did was switch the curve and he was sold... send him a pm and ask him he will tell you the same thing...

if you want to wakeup your bottomend advance your timing... but either way you need new domes if you damanged your old ones... also if you ever plan on going stroker your old porting will have to be redone to change your port timings to accomidate the stroker..

iv had nothing but praises with mine, not a single problem from it.

there is no performance advantage of taking it but 99% of aftermarket clutch perches you have to remove it... you dont have to it just looks getto

big bore domes are for bigger pistons 66.5 mm and up...if your not running big bore dont get them get normal cut domes.. also are you running a stoker? if not make sure they havent cut them for a stroked motor ...

no dont use scarred domes... get new ones... thats where the bread and butter of your motor is at dont risk it by using crappy domes... the size depends on if you dont mind not running pump... i dought going from 22cc to 20 cc will make enough defferance to need 50/50 but the only way to be 100% is do a compression test on your motor and see..

what your elevation and temp? are you running stock carbs and porting? ther are alot of factors needed to help you out..

cool head definantly isnt the first mod to do... yes they are nice having the domes to swap out and they help your motor run cooler until you reach your operating temps, then it dosent really matter... if your wanting fast mods and not alot of money have your stock head cut.020-.030 that wil boost your compression and will cool fine... like the other guy said run t-5's ... do go drag pipes if you inteand on trail riding you wont have the bottom end you ned in the trails

no need to pull the flywheel you can see the adjustable plate behind there... if the holes where it mounts are elongated then you got an adjustable if they are just bigenough for the screws then its not...you can see the edges with the wheel on...oh btw dont use the timing key they are crap.. any time you want to make an adjustment you got to pull the flywheel and they are notoriouse for stripping.. pay a few buck more and get the plate...

first off t depends on how much money you want to spend.. porting is by far the biggest thing you can do for that bike... run you about 300-400 bucks depending on porting and who does it... assuming you got pipes? get reeds to make the throttle response better, if you dont ride in mud or water ditch your air box and run pods.. adjustable timing plate and advance your timing +4 like i said it all depeds hom much your llooking to spend.. you can have all the motor work in the world but if you dont have the suspension to keep that power where it belongs... on the ground it dosent matter how fast your motor is... alot of factors and decisions to make..

well your contradicting your self... boosting your compression mean running high octane... that is unless you dont really bring your static compression up much but then whats the point for aying for new domes? wate of money imo... get your self a adjustable timing plate and advance your tming youll get more out of that and can still run pump...

yes you can replace your kill switch with pretty much any after market switch... Polish uses a CR 250 kill switch on his and has the light to stay on permanently..

yes big bore domes will fit in a normal cool head they are the same size ... its the cut on the domes that is differant..

you could have your tranny done on the banshee and that thing would last forever!

you can get them 265 on ebay brand new... they went down from when i got mine ... it was 280...

Ayman Al Zawahiri , Khalid Sheikh Mohammed, Ramzi Binalshibh , any of these names look familiar? well theres 3 of the leaders in the 9/11 attacks and other attacks on co-allition forces that have been captured scince the beginning of operations... but your right the us isnt any safer today then it was 5 years ago... if you would like i can name several more for you non-believers
