Engine rebuild for more power. Camshaft???

I currently have a stock 82 xt500 engine running a TM36 carburettor, KN filter and a 44mm Exhaust system with supertrapp and 16 discs.

Its been using some amount of oil this summer so now its time for a top end rebuild.

The rebuild specs are.

Wiseco 90mm piston 11-1 compression
49mm inlet valve, stock exhaust and ported head.

I need advice on the rockers, camshaft and springs?

The bike is used for street use and little off-road, but likes to pop wheelies from time to time so i could use some more torque as well.

Best regards

Hi Kasper,

I would take a 88 or 89 mm Wiseco, compression ratio max. 10:1, works better. As camshaft I would prefer a "FS1", it can be used with the stock springs. But of course, there are a lot other possibilities...

Regards Mambu
