I'm on my third rebuild, 1st was wiseco and the skirt broke off... next 2 were vito's, one twisted a ring and caught the exhaust port, the other leaned out and seized the rings. I ride very very hard at high revs, wide open street and dirt riding/ some trails. I was wondering if you guys would think Pro Lites would stand up to the punishment of this or if I should stick to vito's? And if I'm correct pro lites rev a bit quicker right? Might be nice for some low rev take offs/trails. Thanks for looking.

I agree with the other replies but when mine did this, I had big jets in it already (350's). I called vito's and the told me to play with my air screw. I had mine 2 turns out, the told me to take it one out and it fixed the problem. I didn't know that could make such a difference.

Stick with your 450. But I'm looking for another shee, where's it located? I might hook you up with some money also.

I dunno that I would use a holeshit

What part of Iowa do you live in? I'm in Illinois, welcome to meet somewhere?

I didn't say I was hitting, I said it was possible. And IF I was, it would be possible to hit that speed. Now, since I don't have a tach I wouldn't know the RPM's I was at, but I do know I passed him, when he was at that speed. Thats all I said. So please remove yourselves from my dick, and go abouts reading the rest of the forums. Thank you.

Ive had cops swoop up on me and tell me I was doing 100 mph yet my cruise was set on 80?

at 12,000 RPM it might lol. Dunno the RPM, but I was paced by a friends 99 Dakota R/T...

Both tires, 60-70% tread left, possibly rims too, douglas polished alum. make offer.

bump for updates.

My shee runs 96 with 14/41 I can't imagine 17... woah.

Yeah, open up airflow; take lid off of airbox, drop in a air filter. That has a noticable difference. Pipes, Silencers, and bigger jets will really let it come alive.

From the times I've talked to Vito's, (which is alot) Porting, Polishing, and Getting headwork you should seriously jet up, 350 +

eeehehe

Actually what happened was inproper wall/ring clearance. The ring spun and the gap caught on the exhaust port, thanks though. There were no holes in the pistons, the only thing I seen that confused me was the slide marks on the sides of the pistons from sliding up and down the wall. My bottom end is getting rebuilt, and end seals replaced. After it was tore down there was no sign of any debris in the bottom end. The top will be .80 over now, replaced with Vito's SuperStock Pistons. Btw, It wasn't neglect, I didn't know or have the tools to do leakdown/compression test. Now I do, and they will be done. As far as the heat cycles, I did it last time, ran it, checked torque, ran it harder...etc, but I must not have let it heat up enough, 'cause in flatriver the jug nuts came loose. Tightened and it felt fine. Thanks for the suggestions.

Sup guys, I'm from Riverton we just ride around mechanicsburg and buckhart. maybe you can roll with us sometime, its small place to ride, but we have fun.. 8-9 of us go.

Mine was doing this I was convinced it was something major. On the teardown I noticed the screws holding the reeds on the cage where comming out, and the reed was twisted.

The 450's piston return springs are huge compared to yours, you'll never win.

Stock head, hits from pieces of a piston, may need milled, shouldn't effect performance, but small dings.

After the first rebuild, and break in, I ran 50:1 with race gas. I run 104. With the superstock pistons I ran 32:1 with race gas & yamalube, which I will continue to run. I never did a compression test or a crank pressure test.. which I should have done I know, but I didn't have the money nor the tools. Now I do, and I'm getting the crank rebuilt, topend bored & rebuilt, and hopefully everything will be gravy. I flushed the bottom end with Gas mix but never split them and washed them completely. Where abouts in the case would the pieces be? As far as the plug check, the first rebuild it was light colors tan & grey, which should have told me it was lean but the manual said light tan was perfect. I took the engine apart mostly from anger that it blew up again. Then when I cooled off, I read the manual and realized the tests I should have done to pinpoint it.

You adjust your idle on the TORS Caps at all? I adjusted mine too low and didn't get any spark...

My crank is ok, the only thing I'm worried about is the airleak through the seals. The movement sidetoside in the crank is minimal, and it spins freely. I'm going to get it rebuilt before the next top end rebuild.

Ok, my first rebuild, right before I rebuilt it, it lost alot of compression, would barely run and would overhead and spit out coolant out of the overflow. I called trinity racing, they said my headgasket was blown, when I took off the head, I noticed the top of the piston was really rough, and I pulled the jugs to take a look. When I pulled the left jug off the whole piston skirt was missing. both pistons wrings had seized and seemed like they were bouncing off the walls, I presume after the wrings seized. During/After the rebuild I used Vito's Power Pistons (Bore .040), put a cool head with 18cc domes, and didn't rejet from 290's, and ran 50:1 mixture. It leaned out really bad and my rings seized I supposed its because of a mixture of all the above. No cylinder damage was apparent except a small scratch that my machine Dr. honed out. I didn't see the Mic after the hone. This time I used Super Stock pistons, alot more beefy, rings are huge, they're really nice, I rejetted to vito's jet kit, the needle was put on the fourth clip down, and I dropped 340's in the carbs. Ran decent, bogged low end. Well, I went to Flat River and I ran through water/sand mixture all weekend, and there were traces of that in the carbs which I'm sure went through the engine. During the ride the jug stud nut came loose on the right side and it sounded like my pipes fell off. After replacing the nut, it got me back to camp, all the nuts were pretty loose, so I retightened all, and changed the plugs to new ones, and went back out on the dunes. We went trail riding, and one of the plugs got fucked, wouldn't fire no more, I think it got wet earlier from being under my seat. Well, I rode about 5 min back to camp on 1 cyl. with the other one backfiring most the way. Keep in mind this is my rightside cyl. I got back home, and Monday I started my shee up and took it down the street. It seemed like it would lose power right at the end of the power band. Vito's told me to take the air screw all the way in and back it out 1 turn. It pretty much fixed the problem, but about 20 seconds after that it blew up lost all compression. Died. Upon closer inspection the ring must have turned, prolly due to the ring to wall clearance from the hone, but the ring came off the pin, spun and caught on the exhaust port. The pistons had slap marks all over the sides where they had been sliding up the side of the wall, the left one especially, the one that had the scratch that needed honed. The left piston looks pretty good, small amount of sliding against the cyl wall, a small chunk taken off side of the very top. Is there anyway the crankseals are comming into play with the badluck streak I'm having? Any info/opinions are GREATLY appreciated. I dont want to sell my banshee but I'm not going to be able to afford many more rebuilds. To get the current scratch out Its going to be on its last bore, and I would really like to have a dependable bike for a while. P.S. I'm going to switch from the airbox to Dual K&N filters with outerwears that will get rid of 3 possible airleak spots, free up alot of space. Sorry for the long post.

No I just ordered Vito's jet kit, which comes with a -longer- needle I believe... not sure where to start with this new setup, except the reply I got earlier, start at the most fuel and work my way down, but thats an awful lot of work taking the carbs off and on like that... I dunno, thanks for the help.
