Im not saying you made it lean or not,the bike pressure tested perfect with no leaks,the base gaskets didnt leak.I dont know what transpired. The base gaskets can most certanly leak if its hot enouph,the bike got to my house everything was loose,base bolts.Studs stretch under heat.You might be rite about 66mm bore but why wuoldnt jeff from fast know that when we ordered domes and everything else. Ill check tommorow on the domes with jeff and timing is still at +5 didnt move.Ill let U know how it looks

detonation causes plugs to back out, detonation causes heat from firing speratically,its a brand new impellar,engine ice was in it,two tanks of gas engine didnt come above 140deg,I agree his new horsepower might be a little much for a new banshee owner.I couldnt see the shee getting that hot,in that short of time unless it was detonating,the only thing diffrent was octane at first ride. Wacko 2000 how did you come up with 108 octane,was anyone running his compression and that gas

would both base gaskets blow due to heat has anyone seen this before? would both base gaskets blow if detonating was accurring obviously this thing got really hot,im gonna rip the cylinders off tommorow and deck everything up is there a chance the cylinders or cases warped.Has anyone ever had a cylinder worp. Someone has to have had this happen, how far do I go with taredown,does anyone think mainbearings are cooked??????????

Wha size sled carbs,and what type of mikunis

When my bike was mild I went to a local spot,my bike beat everyone except a piped 700r,I couldnt beleive how bad hewas walking away from me!!!!!!

He was running straight 110 when he left I also dont like to be on the border with anything. I ran two tanks of gas through motor with no problems at all .I just put new o-rings in the head one was garbage at base of dome.Just did a pressure test on motor both bas gaskets are leaking like a faucet now.The motor left me perfectly sealed up holding six lbs for six minutes with no leakidge.now wtf could he have worped the cylinders or just blew the gaskets out due to heat

I use honda 80-85 weight

Just got #1 Banshee bike to my house after his glamis trip.He blew an o-ring do to heat on right cylinder,I beleive the heat was caused by running not enouph octane with 175 lbs of compression.I just tore head off and cleaned everything up cylinders look fine and head is not worped,domes not cracked. He changed the o-ring at glamis. Here is where it gets tricky it happened again at glamis after riding for a little this time the upper hose off head melted hole in it,same with hose off the front of head.He used Home depot hose for coolent and it just didnt hold up.Could this have been caused by lean jetting.The reason it concerned me is the fact that I sent the bike there running perfect on 192 mains 55 pilots. I got the bike back with 172mains 50 pilots.I live at sea level,glamis is sea level. Thirty degrees temp diffrence shouldnt of constituted such a drastic change in jetting or should it.I also dont know all the sequences of event from #1 banshee

Is it hard all the time or just when motor is on,next u probably dont need new tranny maybe shift forks,clutch hubs/parts. you need to have someone look at it or start easy with clutch parts so you dont have to crack cases

I need a set of stock cylinders,stock bore for back-up let me see what u guys have

Good luck buddy call me if u got any issues

I had one that was stripped out once I carefully tapped the three holes in the flywheel to 3/8-16pitch and used an automotive steering wheel puller,worked fine.Or buy one off one of the site sponcers for $15 and have it forever

I would say you had the clutch springs to tight and when it got hot it snapped.They say 7 lbs in manuel but I use 1/4 drive ratchet 6in extension one hand snug. When u took off your cover did the kicker gear rotate at all,it just sounds like its not sitting rite,then it caught. In my opinion change inner /outer hub its only $55,your springs should be fine and youll need new studs.Make sure the washers on the motor side of basket and inner hub side are in rite.

Was there a pressure test done on your motor after the crank was put in. Did your builder use new seals?????

It might run. But how long???????????????

Is the problem side same that u changed carb on? Try swapping plug wires see if problem travels to other side,did u resync your carbs and how does your slide heights look at idle(same or not).Check reed on that side

I dont care if you know i would have told you if u asked.

If you truly want to keep it hit me up I live close and might be able to work something out,you can call #1 banshee hes seen my set-up ill try and squeeze u in I woul;d hate to see you get rid of her,Ive have had my share of fourstrokes, I even started quading on one they get boring quick!!!!!!!!!!!!

I ran at the track a few times,1/4 mile only my gearing was 17-40,inframes,drag port.39s,strut in back and wheelie bar.I was a little dissappointed at the times but it was second tank of gas and untuned,full chassis and not knowing what im doing on a tree(much diffrent than street dragging). I ran a 12.41 at 98mph, since then i ordered out of frames and an overide and well see how it goes this year. I noticed that mph is not everything because my buddies 421 cub ran 12.53 at 101 I didnt pull as much mph but ran quicker

If your running drag pipes and everything to support them 39pwks is what I would do

With your mods I would stay 3 heavy 3light,scuff them with scotch brite pad,greg is a chill guy ill see what happened to his shit on sunday

I agree u cant run that carb,but why would 38s be be to big,I run 39mm carbs on a 4mil

What he said,more info on mods

I the bike runs like a raped ape leave it,with a 420 main you betta be putting some serious hp out,it might run fine with the big jets if your port supports it.Have u run it against another good running banshee

I was told there is acceptable loss but im a perfectionist,You can make a leak down tester for $20-$30 dollars at local hardware store. I wanted know octane value because premium is diffrent in certain places.If your running 93 with no problem you have decent porting with 20cc domes Also keep in mind a notorious air leak spot is behind the clutch cover,through the keyway on the primary drive gear,if keyway doesnt have case sealer all through there you would be extremely lucky to not have an air leak.
