Hi my TT1 replica has a 750 paso motor with standard cams do you think
I will benifit from fitting St2 or 900ss cams its a road track day bike no serious raceing.

I will weigh in since no one responded yet. The stock cams you have run out of breath around 9000 RPM, and take a long time doing the last 1000. Any cam with more duration and lift, like 900SS cams, will help. They are also as close as you will get to "drop in"; I do not believe there is a valve-to-valve conflict in the 750 heads. They only concern might be the depth of the valve pockets in the stock pistons, which isn't much from those I have seen compared to "race" pistons; the latter often being high compression pistons. So, you might end up having to do that too. Then you start thinking about bigger carbs.................sorry, my mind wandered a bit there. And on it goes once you start. MikeV

Hi thanks for the information, have you or anyone got part numbers for the 900 or st cams?
