Think I am going to do and upgrade this winter from stock 88ci to 103ci, a buddy told me it should take me to 108 hp, any advice from you power hungry riders on this project? Wish I had the money to go bigger.

 

Going to 103 from 88 is pretty expensive. You'll be swapping out your crank, the bottom end has to come out and the cases split.

You can go as big as 98" with just a top end build, save the money you would have spend on the crank and put it into your heads. You can pretty easily build a 100-110 hp 98, as long as you've got a good plan.

Not much difference to go from 88 to 95 or 98. If you do install a stroker crank, you can build to 103 or 107 for pretty much the same price.

 

Thanks for the info, I welcome any more help anybody may offer. This will be my first big project, and the most expensive one, and want to make the right choices.
