I joined up to tell a P11 modification story, and it's basically done. Well, I'm done for sure.

I'm checking out until I get in a dyno run and have something to add. Somebody might want to know if all the parts I used really make any difference. I don't need a dyno to know I'm making more HP than a stock P11 ever could, but that isn't saying much. Besides I am curious myself.

Unsolicited harsh advice section:

If you get an itch to install a JSM cam kit in a street motor, make sure before you lay your money down you are going to get BSA lifters, and not Triumph lifters. There is a significant difference. My advice is get the stock tappets radiused for use with a JSM cam on a street bike. You won't notice any big difference with the lighter lifters riding around on the street. The bronze blocks are a tedious job to install. Looks easy in the JSM video that covers the install, but the install has to be perfect to stop rapid wear of the bronze lifter blocks. The stock tappets are a piece of cake to work with.

Be well and prosper.
