Mxjd619 Posted March 18, 2017 Report Share Posted March 18, 2017 Hey guys, deciding weather or not to bore out current cylinders as they are scored up from an accident, or just by new. My question is are all the cylinder kits available on amazon, Ebay, etc.. They all seem to just be the Niche Cylinders with various piston kits and gasket kits that determine how much they sell for. I can find what looks to be the same (niche) cylinder +piston kits from 200-500 depending on if it comes with weisco products or some cheap crap. So i saw a couple older threads on this but nothing that really helped. Anyone have experience with any kit sold by ebay, amazon, 50 cal racing, etc. Its 120 for me to bore to next size prob, 64.5 or 65. Are these cylinders worth they 200 bucks regardless if the pistons are crap? Doesn't seem to be to many people that have messed around with them but any help is appreciated guys. To bore or not to bore. Quote Link to comment Share on other sites More sharing options...
bigweav81 Posted March 18, 2017 Report Share Posted March 18, 2017 What is your current bore size? Sent from my SM-S820L using Tapatalk Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted March 18, 2017 Report Share Posted March 18, 2017 The niche are not as nice as OEM, but totally workable if you let a builder touch up ports. What's your budget and what are your intentions? You could be money ahead buying a nice set of used stock cylinders that are already ported with the needed domes. Or there are the Driveline Cylinders. They have been getting stellar results for he price. Quote Link to comment Share on other sites More sharing options...

Mxjd619 Posted March 18, 2017 Author Report Share Posted March 18, 2017 I crashed it and long story short, lost radiator fluid and broke both pistons on the exhaust side.Finished putting the case back together cause there was crap everywhere in the case. Ready for top end now, My budget is like 500, if i cant get away with buying new for that then ill take it to the shop. Quote Link to comment Share on other sites More sharing options...
Mxjd619 Posted March 18, 2017 Author Report Share Posted March 18, 2017 Bp has a set i think thats like 300ish. I figured if the new ones are "As Good " as OEM then ill by them as a kit and just get the stock ones bored and sell them, ill make my money back probably.

Mxjd619 Posted March 18, 2017 Author Report Share Posted March 18, 2017 so the real question is are there any companies that sell OEM quality cylinder sets out there for my budget or at more reasonable prices besides ordering directly from Yamaha themselves for 500+ a jug?

Mxjd619 Posted March 19, 2017 Author Report Share Posted March 19, 2017 Thanks for the advice guy, I'll just drop them off at the shop Monday and that will be that. Quote Link to comment Share on other sites More sharing options...
bigweav81 Posted March 19, 2017 Report Share Posted March 19, 2017 Niche are usable, but they have so many casting flaws. If you were to buy them for porting purposes, and buy decent forged pistons they are capable. With that being said oem > niche. If you have $500 already, then I'd save $300 more, and go driveline.
