4milstrkr

The last time I put a new top end in my banshee was in march of 2009. It is stroked 4mill, bored .40 over slight port job, cool head with 18cc domes. I haved noticed a loss of power and my compression has droped to 160 psi. and it still has the spacer plate under the cylinders. My big question is what whould i replace if i rebuild it and will removing the spacer plate and have a set of cut domes thrown in will I notice a difference. The crank was put in summer of 2008, how long do the bearings last on a hotrods 4mill crank

before

i really noticed it after i put the 18cc domes in the bike, im runing 114 octane fuel, stock carbs with a 340 main, 800ft elevation. and the porting i did myself just narrowed the bridges and smothed all the rough edges

filter is clean what could cause a bad spark, i am also having to shrink my plug gaps

plugs look good, about 170psi

i have a 96 banshee, procircuit exhaust, ported, 4millcrank, 18cc domes, nology profire coil, bored .40 over, rad valve, rmstator ignition, my bike has a bad high end miss in 5th and 6th gear. it pulls harder at 1/4 throttle in 6th gear than at full throttle, and the jetting is perfect what could it be????????

do i need procircuit specific o-rings for my procircuit exhaust?

i want a good high quality twist throttle and cable currenty have motion pro turbo throttle and cable but the thing just has to much slop, have adjusted many times and cant get it right

i have a 96shee, procircut exhaust, toomey clamp-on uni filter, bored .40 0ver, +5 timing, 4millstroker, mildly ported cylinders, prodesign coolhead with 18cc domes, nology profire coil, and aftermarket cdi. but i still have stock reeds and was wondering if the vf'3 would be worth the 230 price tag?

thanks for the tip mine are also numbered 1-1 and 1-2, i looked in the clymer manual but it didnt say anything about it

i am currently rejetting my carbs for the winter temps, and i was just wondering if there is a difference between the left and right carb bowls on stock carburators

what kind of carbs and what size

i use it for recreational riding and i do race flat track with it i have the timing at +4 and just 93 octane for gas

i currently have pro circuit pipes k&n air filter adjustable timing plate 4mill stroker cylinders have been bored ,40 over and have been cleaned up, and a cool head with 22cc domes stock carbs with jet kit i dont know what else to get any help would be nice

310 mains stock needles and pilots took stock pilots and needles out to see if would make it run better and it didnt i just rode it lastnight and the left side pipe only fires every now and then until u go above 1/4 throttle and my elevation is 600ft stock carbs
