    Very nice looking Rickman.

    Your TSS will eat it for breakfast though !

    I actually thought at one point of dropping the TSS motor in the Rickman frame. I even had the TSS head polished out by Big D Cycles in Dallas and bought a 900cc kit from them, but work, kids, life...just never got around to do it. Now I think I'll be content to keep both bikes as they are.

    I built a 906cc 8 valve Triumph race motor, it was awesome.

    My current Cdo is pretty hopped up and is quick on the road, it’s got 65rwhp. The 906 8 valve produced 84rwhp on the same dyno.

    It would be interesting to see what the Big D kit consists of...

    We're headed out for the evening, or I'd take it out of storage and send a pic. It's basically just an overbored block with pressed in liners, overlength stainless steel studs (you have to weld/build up the cases to allow for boring/retapping the longer threaded stud ends) and crank assy balance instructions. I haven't looked at in years...that's all I remember.

    Leave it in storage Robert, or put it on eBay, that’s my advice. You’ll create a seemingly ever ended list of knock-on jobs if you were tempted to use them!

    Oh.....Duh.....How do you get 908 cc's from a Triumph? Do you have dyno readouts? I'm interested in that sort of thing..Tim Joyce,a past leading AHRMA Triumph rider was getting about 70-75 RWHP from two valve Triumph 750's with extensively modified heads

    I also got just shy of 75rwhp from a 2 valve Triumph, but it was 840cc and had squished heads and etc.

    The 906cc wasn’t really a Triumph per se, it was a Nourish in Triumph unIt cases, albeit extensively welded and strengthened, 80.5mm bore and 89mm stroke, 180 degree crank, Dresda cam timing (based on Z cams but with more duration), 38mm carbs and ports, 11.5:1 CR, blah, blah. A very quick bike.

    Actually, IIRC, although it did produce 84bhp on the dyno, that’s not how I raced it. For some reason that I don’t understand, with 1000 series mk1 carbs it produced a much fatter torque and power curve than it did with smoothbores. Whilst the 1000 series carbs produced less peak power, the overall power and torque characteristic were better. I think in this set up it produced 79bhp and that’s how I raced it.

    Have you thought about flat slides? Mikuni TM's are inexpensive and from my experience, easy to tune with great throttle response.

    I don’t have the bike any more Hillbilly. If I did I would definitely try other carbs. CRs if I was still racing (due to rules) or FCRs if not.

    It would be very interesting to see what kinda difference they made.

    Anyone have a stock TSS on a chassis dyno?
