Im just saying boring makes power. Which is why industries make different engine sizes. .050 will make the banshee into a 369. and I can go to a .060 but there needs to be a little room to play.

So basically what u just told me is that a mopar 440 has no more power than a mopar 383? Boring makes power, I know that, which is why I am considering it. Stroking the motor will cost me alot more $. I will do my own porting because we do porting on snowmobile engines as a side job. I could probabally have a deck chop cheaper than I could buy domes. My main question is Should I just port, chop the head, and refresh the top end and seals. OR, Should I port it, Bore it, and Chop the head. If the cost difference is only going to be $50. After Hearing it Im going to send the crank out to get trued and welded. Here is what I came up with so far. Pistons No matter what size of pro-lites I buy: $82 complete with 2 pistons, pins, rings, and 2 caged bearings. Piston ceramic coating: $50 Full Gasket and seal Kit $50 Crank True and Weld: $40 Head Deck Chop or new domes: $50 Boring(If I decide to): $60 Porting: $Free

I have no Idea what domes are in it now, I bought it the way it sits other than some cosmetics and removing the overflow bottle. I was thinking about boring it just for some extra power, I knew that I may need to bore it if the cylinders are a bit worn on. The pistons cost the same as regular bore, and boring costs me next to nothing. Also Is the 350 a sleve motor or a nikasil motor? I'll Look at the shee and see if it has a timing plate when I pull it apart.

Ok guys, I need your help on this. I have a 98 banshee with T-5's, a cool head, and a K&N pod. I am going to rebuild the engine this spring and just have some ?'s. 1st: What compression PSI can I run on 91-93 pumpgas? 2nd: Should I bore it over .050 or leave it stock? but either way it is going to be ported. 3rd: Should I pull the crank out and get It trued? Currently I have 115/120 compression. Any help is much appriciated, Thanks.

Recently I went to start up my banshee and it will not run over 3000 RPM. I do still have the TORS on it but have bypassed them, therefore theyre not the issue. Could my ingnition box just have taken a shit??????

Hi guys, I was looking for a good site and found exriders.com and on that site it had a link in a thread over to this site. So first I should start off saying that I do know a little bit about modding motors but want some input on this one. I have a 98' banshee with toomy T5's, a cool head, and a k&n pod system. I bought the bike last spring and have tweaked it a little bit so far. The compression is 115/113 (mag/pto), I saw that stock banshee compression is 6.5:1 so the compression isnt too far off. Here are the Issues I still have to deal with: I do hear kind of a different noise but I could be wrong and I belive it sounds like piston slap. So I am a little scarce of riding it and breaking a skirt of a piston. The other issue I have is a coolant leak. I have a slow drip leak out of the shifter seal. My thought is that it is a 98' so maybe time for a couple new seals and an engine rebuild. I found a cheap set of wiseco prolite's for the shee and always have run wisecos in my sled. If I find out that the piston is a little loose of a fit I may bore it to a 376 or just fix what I have. I do not know what cc domes I have in it at the current time. Thanks
