Belt Drive.

Hey there Jeff. What do you run for timing set up on your motor, Belt drive, or chain set up. I have has issues with my 505 with the Rollmaster red series cam sprocket and Simms torrington thrust plate deal. I have 50mm roller cam bearings and for some reason, I have had issues with wear problems with the cam sprocket. I need some advise on this to correct the problem. Thanks, Mike.

Hey Jeff. I was Interested to know what you guys modify in the main are of the aftermarket blocks. I enlarge the oil holes slightly and also to the main bearings. Do you have any Info on mods in this area. Thanks.

Hi Jeff. Do you have any pics of the Aluminum block oil hole mods. I have my IA2 apart and wanted to see what you have got going on in the main saddle area. Thanks, Mike.

Yo? Did you go to William penn?? i privately emailed you as well.

Happy brithday Jeff.
