Theres absolutely nothing wrong with Wiseco pistons. Theyre all Ive ever run, and Ive been riding/racing for 10yrs. now, and never had a top-end failure. I'm sorry, but I'm going to have to respectfully disagree. [img]i/expressions/face-icon-small-smile.gif[/img]

 

That would be correct. Once a cylinder is overbored you have to go with the matching piston diameter of the bore. And as far a replacement intervals, it depends on how many hrs you put on your bike, and how hard you are on it. What you will want to pay attention to is your piston ring gap, your compression, and just the general condition of the piston. Does this mean you should periodically pull down your top-end and inspect things....yes. Does it mean you will need to replace the topend evertime.....depends on how you ride. Let your specs tell you how often you need to replace things, not your buddies with the deep pockets.....that is unless They're willing to pay for your topend kits.

Thanks, That was a relief, I was starting to think that It was going to be a money pit that would have to be redone every season. I don't ride that hard so I should be able to get a few seasons out of the top end. I can handle regular rebuilds, I just didn't want to have to buy tons of new parts alot. I only put about 15 hours on the bike a season, cause I cant get out that much. I can't drive alone yet so I have to wait till dad want's to get out and go riding. see ya, gotta go!

15hrs a season?! Yea I think that'll last you a while. I put approx. 60-80 hrs on 125's between topend replacements when I used to race locally. That would usually get me through about 4-6 months. Glad to make ya feel better.[img]i/expressions/face-icon-small-wink.gif[/img]

 

maybe a little more than 15hrs, I don't exactly know, just made a guess. I'm 14 right now, and as soon as I can drive alone, I'm gonna get out to ride alot more. [img]i/expressions/face-icon-small-cool.gif[/img]

 

Wiseco's are basically a moto-to-moto piston. Thats why they are cheap. Wiseco sucks...IMO...[img]i/expressions/face-icon-small-smile.gif[/img].

 

...To each there own...

 

Bryan, make sure and warm that puppy up good before taking off......don't want a seizure!

 

Ill never let anything but forged pistons into my engines, i dont like to pay for weak cast pistons breaking a skirt and destroying my bottom end but like Flyinbrian said to each his own...

 

I have a forged JE in my Raptor.....so I am not a "cast piston" only guy.....I like too ride instead of fishing pieces out of the bottom end...[img]i/expressions/face-icon-small-wink.gif[/img]. Like you guys say...too each his own. Later gentlemen.
