Good going you got it sorted!

Im 6ft 2" and 16 stone and my bikes got a 38T rear fitted. It will pull flat out in top with no prob so yours should easly pull you with that gearing.

With stock pipes the bikes do pull well and only have a small kick at 8 tho, but tend to run out of puff (not much over rev).
