Thanks, however my last post was to answer 2 previous questions, not to give any new information.

The key for me is what you said about theoretical high top end if you can pull it, this is why I am now looking at the next set of changes to my bike being for performance (hence the EFI tuning post).

I do have to say though, if your happy just below 100mph, then changing to a 34T front rear drive pulley is a big improvement. In the last 3 weeks since having it done I have covered just over 2000 miles, its been the nutz.

However, I now see the drop off in pulling power about 95mph, so .. Matts and EFI tuning post here I come.

Gonna sign of from this post now as feel the conversation has been to death.

Cheers, Roy
