RooR

what size rods?

Welded short rod crank...T5's CPIs or shearers

how much for topend setup minus the coolhead and the crank?

I was told my domes were cut to match the WSM 68.5mm pistons at 10 degrees? does that sound right? I was thinking 9 or 13

soo i just went and rode her around for a few miles...first of all wow what a difference from my stock cylinders. I was worried about my SST pipes choking back too much power, but i don't see myself needing to change pipes for what im gonna do with the bike...but it ran really smooth and never vibrated or sounded bad or harmful. just a vibration around idle I am worried that the fuel could be the problem...its turbo blue 110 but its probably been sitting in the tanks in the gas station since this spring...I'll probably order some vp110 to see if that makes a difference. I left the engine in the frame for the rebuild...the pistons wernt broke they were burnt up on the exhaust size, the rings were broken but still in the groove and all pieces were accounted for Ive rebuilt alot of engines, top and bottom ends, and all the crank bearings were really tight...I am worried that the crank is slightly out of phase Im thinking a bottom end rebuilt isnt far off... +4mm?

guys i know that the bottom end needs beefed up but, the crank hasnt twisted yet....its made this vibration since the second i first started it after rebuild....its only been ran at idle so far

i didnt touch anything in the bottom end... would going from stock to a ported/high compression engine make a difference with vibration? it was very smooth running before the rebuild... i noticed it as soon as i started it up for the first time.....i may just be paranoid?

how would a leak cause a vibration when it runs fine? 19cc domes on 110octane +4 timing ported by HJR everything chamfered to me it doesn't seem like the coolant system is circulating at all...there is coolant in the line up by the pump cover the vibration isn't very abrupt...more subtle but i definitely notice it no noticeable white smoke to indicate leaking coolant?

the pistons never seized just very low compression...they were the stock bore pistons

I just got my banshee put back together after porting and adding a cool head. it started right up...idles fine sounds good except there is a noticeable rattling/vibration...also im not sure that it is circulating coolant the coolant lines feel limp.... the bottom end seemed really tight when i took it apart and the water pump was fine. do I have to prime the cooling system? I am worried that my chariot cool head didnt seal properly...also wondering if the crank could be out of true?

I emailed and sent a message no response...

i have i really nice set of FMF SST pipes that are awesome for a stockish bike, id love to trade, i could even throw in some $ also interested in the crank and clutch ur cranks a 5mm long rod stroker PM ME!

so im thinking of going with this set up; Fire ball +3 a-arms Fox float 3 shocks rath or durablue sway bar kenda kutter xc fronts Possible R1 rear shock? -2 swinger +4 axle?? c826's in the rear

if it just needs a true & weld that's no problem.....what I need are specific instructions of what needs to be done, not everyone telling me that HJR sucks and my setup is crap, the parts are paid for it is what it is....im sure that this thing will RIPPP compared to my bone stock banshee

gotcha, im an idiot lol

Thank you this is exactly the type of info im looking for. When your talking about LT arms are they lt250r or ltr450? do these require modification to fit? is it beneficial to run a smaller front tire to get the front end lower? I'll start doing some more reading!

Im going to be setting my shee up for flat track and ice racing, Im starting to look into what im going to do with my front end and finding a lot of options. Whats the best way to get to the correct width and ride height? Ill be using yfz450 shocks a arms wheel spacers offset rims Lowering and widening kits that change a-arm mount location Lowering and widening kits that change shock mount location also using a sway bar with any of these?

I love that serval motor, I was thinking that was the route I was gonna go. But I got the WSM cylinder ported ready to go for the same price as rebuilding my topend and porting. the same setup on a serval was over $800 more.....that's a lot of coin! for basically what? better port timings? I thought Id be safe having a site sponsor do my work, now ur telling me hes no good? what do you guys think of redlines Pro-mod trans?

soo im looking at.. true and weld crank, billet clutch basket. I already planned on pancake bearing and shift star/shaft. max load crank bearings? I just didnt like the idea of getting into a bottom end thats in perfect working condition. when i said later i meant separate post

Banshee quit running the other night, opened her up to find the factory pistons the rings in pieces. soo I took the plunge and built it back up the way Ive always wanted too. I left bottom end and clutch alone for now, ill get into that later. 68.5mm bore WSM sleeved cylinders 398cc or 417cc? bore to 71mm TT/ICE (basically aggressive dune) port by Kevin at Herrjugs Chariot Billet Head 19cc Big Bore Domes.. 110octane ? Shearer Small bore Inframe drag pipes V force 4 reeds 1piece billet intake with crossover 35mm Keihin PWK 6" k&n w/ outer wears billet timing plate, 6 degrees per kevin What do ya think? Am I overlooking anything?

I would like to set the shee up for casual ice racing in the winter & fast curvy back roads in summer, maybe occasionally dune. my budget is $2000 for engine mods, I'll deal with chassis and controls once i know what Im doing with the engine... my hopes are for something that's "scare the shit out of me fast" , I want the feeling of when i rode my yz400 for the first time!!

My current Banshee is stock besides V force 4 reeds and SST pipes and silencers, clamp on K&N's. Im looking for more power but I cant do the motor mods and be able to afford new pipes... Im considering either a +4 & porting kit for my stock cylinders from a site sponsor OR a serval 421 kit....I know the sst pipes are somewhat limited do you think that I"ll have problems with these pipes with the setup I want? Also what kind of mods should I be doing to the bottom end to support the extra HP?

on this quad ill do mostly fast trail riding and alot of fast open dirt roads, i dont really dune or drag alot, but i do want some top end power... ill ride the raptor if i need low end for tight trails
