Stevem should chime in here.....
He rebuilt his motor using wiseco pistons (much cheaper than stock ones), and had lots of hp, until it went bang on the main straight.

I'm not a fan of modding motors on track bikes, as they run 100% of their use at 10-tenths. Having a modded car motor, say, and you only floor it for a few seconds once in a while, it's not very highly stressed. Unlike a track bike.

If you've got deep pockets and are willing to rebuild it frequently as a preventive measure, go for it.

Also, have a look inside first. I was sure that a motor that dropped a valve at idle would be relatively fine inside, but the bores were very slightly damaged and it turned out not being worth fixing.
