12.5-1 Wiseco 5.63 mm over piston

Think thats the 558cc 104.84 bore piston

Can you just bore the stock cylinder?

Or do you have to re-sleeve it?

 

HPD sells a 558 kit , you re-sleeve it

 

How many cc's will the predetor have with the Wiseco 5.63 mm over piston? Is it 558 or is it something smaller?

Whats the largest bore you can go with the stock sleeve?

Thanks,

 

i have no idea, i know though that you can get a 600cc bore kit from HotSeat

 

Ok, I now know its 558cc

Will it be safe to just bore the cylinder?

Must I re-sleeve?

Whats is the biggest you can go without re-sleeving?

I have mine torn apart now cause of a broken piston at 20hrs on brand new 04 engine that Polaris gave me for my 03 TLD Pred. Yes, I never drive it.

14 hours was just sitting brake burning tapped out in 5th gear until it would get so hot it would quit. Then cool off and do it again. Yes, I'm amazed also it last that long seeing as it would be boiling fluid each time also.

I don't plan on doing this the second time around by the way. lol

thanks.

sounds like your running SUPER rich to have been overheating and cracked a piston. as far as i know, the only bore kits out right now you have to re-sleeve

 

Quad is stock. I figured the reason it would burn out till it quit was because there was not enough air flowing through the rad with just the fan running and not any extra air from the bike actually moving.

Guess I'll either leave it stock or find a sleeve also.

 

well if your just sitting there doing a burn out with your engine rev near maxed out then of course your going ot have cooling problems. but if your running it hard and fast then there shoudlent be a problem at all. the fan comes on alot because its set to come on at a lower tempature to keep the engine cool. i have no idea why your piston cracked though if thats it though
