i did my fm 107 kit in feb and lovin it. due to take it in for the dyno on saturday. but last month I had a rear tire put on and the tech took it for the test ride mentioned clutch was slipping a bit, asked if I had the clutch spring upgraded- no. I didn't think about that at the time of the build (DAMN), so did some research and found its a good idea so I'm doing that too. apparently the engine make a little more hp than the stock clutch can handle. just something for ya'll to consider during your upgrades

I've also got an SE103 with 255s. Once you get your 555s installed I'd like to hear your impressions on what kind of power difference they make through the rev range. Any chance your dealer can do a pre-install dyno run as well so we can compare the sheets?

Got a buddy with the tw 555s in a 96 and a buddy with 255s in a 103. That 96 with the 555s will leave that 103 in the DUST. You will really feel the difference with the new cams congrats.

Ordered the FM pushrods, Woods directional lifters, and the cams. Install scheduled at dealer for Tuesday the 26th. Dealer will also install the new HD oil breathers...maybe that'll help with my blow by.

Looking forward to see if there will be much difference from my current set-up. 103 stgII(255), street port heads with slipons. It'll go in the booth for tuning right after install...

Cant wait...

I predict 94hp and 114tq. But then who am i to say? I'm a coolerman!
