Collari Siro 5 port
 

Hi,

I just acquired this motor where I was told it was just run in. There is a lot of compression left, however I am having problems with it. It basically has no low rpm in the engine. I have JP which works prefectly so I know how to tune engines. I have tuned and adjusted the clutch to suit however it still has no grunt at lower rpm.

Any suggestions?

Thanks
