I would be the guy Nutty01 is talking about. Haven't been on this site much at all. Coincidence I would stumble on this. Lots of builders out in the sled world have great products and options.
In response to the demeaning post to SHR's info....
I am a rider that happens to have work done by Felkers, Holz, Crank Shop, Fox, and the final (Dial In) by Sled Head Racing. Lynn Felker spent much time giving me updates and everything I asked for with the initial purchase of my sled. Trygstad was the original builder of the 880bb I purchased. Holz and Fox followed with all set-ups with suspension and reasons for build specs. I made 2 phone calls to get configuration specs and setup info from Trygstad. My intentions were to get crank info, pipe, piston, compression expectations, rpm limit, etc. etc.... in addition I wanted a new top end to freshen up motor. because I wasn't original purchaser from him he had no info for me. Said he was done with the 880 thing. Wanted nothing to do with it... think nutty01 has confirmed the inadequate service I received with my requests for info and parts request.
Already knowing John with SHR. I came to him with my blown up motor, burn down due to not getting the information I needed.
SHR took a fully ported , trygstad, top and bottom end and totally rebuilt it with 100% brand new parts. I didn't have a ton of time to ride beginning of '13 year, but the time I did was nothing less than ridiculous. nutty01 is a turbo guy and his sled Screamed, however the 880BB SHINED in the areas that a BB is Strong!!! As my friends would confirm, there has been little money spared on having the best and if SHR is saying he has the set-up ready for the 14's, then be rest assured he does.
