Im going with the 730 big bore with the 48 hv and race porting and all that good stuff. i know it will be a strong bike for the drags, but will i be able to play around on the dunes? the motor is gonna be 100% hp research. i heard a good drag bike doesnt make a good duner. i know i will have to extend it out but will it be good for those huge dunes?

 

It will be a great dune bike!!!!!

 

I am currently running the exact motor as you describe and it makes a great duner and trail quad.

I am running 100% hp research engine parts, 730, race head, 13:1 compression, HPR-3 cams, ported intake, and KMS fuel injection. If you go with more aggressive cams you may lose some of that dune and trail riding ability. I am running the stock swing arm which makes it allot of fun trail ridding and in the ruff stuff in the dunes, the front end can become very light when you want it to.
