Phil Gordon races one in amateur stuff at HPT.  Either way, Mike Himmelsbach should be a good resource to you.

I'm probably only in for BHF this year. Lil Thorny is his handle on this forum, i forget his name but met him at BHF last year.   
There are not a lot of people racing the triumph but that makes it all the more fun. And they sound way cooler than inline fours.
Phil Gordon is a great guy to know at HPT. He was able to find spare parts between races for the 675 after my crash.

I've been running a 675 since 06 at HPT.  Gearing:  I feel best with a 15/48.  SuperDave and Scotty spent a lot of time working with me over the last two years to get my suspension to work good at HPT.  I run one of the original Penske double rears and had GP Suspension do my forks in late 06.  GP removed my bottom dampening valve to get more travel. 

Chassis setup:  I have seen a few bikes that run their 675 forks flush with good results, but I have ran flush mounted forks and it seemed to tuck pretty consistently in Turn 7, 12 and 14.  I run a few mm's below the face of the upper tripple clamp and like that better.  I have tried a few times to find a way to lower the back end, but to my knowledge, Triumph still hasn't got a part number on the swingarm mount shims that were supposed to be out 2Q of 2006 !!.  The rear shock upper mount is non adjustable, but if there is a way to get the rear end down a bit, I think the bike wouldn't need such a high-rise front end.

I got my Penske before Mike started officially working for them, and actually got to see the first Penske stuff at HPT in early 2006 on Mike H's bike that year and was very impressed.  I always had wallowing issues under accel. out of turn 8 and couldn't figure it out til Scotty and Dave found that my rebound dampening wasn't working at all.  Ended up having to rebuild the shock a couple times to get the rebound valve adjustment range within a useable area. 

We ended up figuring out that anything you can do to get the back end down helps lap times.  If you're at HPT in April, stop by.  I'll be on the Red 675 still sporting yellow plates  .

Thanks for the info, Phil.

I've got 15/48 gearing on the bike now, so I'll start with that at HPT.  It sounds like my bike is set up very similarly to yours.  I just bought my Penske shock last fall, so hopefully they have sorted out the issues that you had with yours.

I do plan on being at HPT in April, so I'll try to you look you up there.

Thanks again,

Roy

Sounds like a plan.  See you there.

Grashpr did you run any CCS  MA last year??

+1.  I think I made 3 rounds of GP last year before blowing the motor.  This year I'm on it though!  Got a Backup bike plus a 2nd backup motor.   Gotta Love Triumph.

Lil Thorny is Benji Thorton - He rides well... I think he did 2 races last season - after sitting out a couple seasons and was still able to get down into the 12's at BHF.... Not too shabby.....We just rebuilt Phil Gordon's 675 suspension - Front and rear... He sent the old original shock valving to me so that I could take a look at it - and I can understand why his shock worked like it did before Himmelsbach revalved it.. It's my understanding that the newer 675 Penske shocks have valving very similar to the update that Phil has now.... WIth that said you should be good there...

As far as the taller front end - That along with the offset bearings will be much better for feel....

Phil - I am interested in this rear shim that you are talking about - Can you email me a picture of the stock one with some dimensions? Might be able to make something happen with that - We do have a CNC machine shop and I might be able to employ Mark to make some of these....

Thanks, Scotty! Will you be at HPT for CCS in April?  Or BHF on April 15?

That is the plan :)

The shim is the swingarm location bolt surround.  It's kind of like the old ZX7RR's, just not as much adjustability.  Triumph still hasn't offered the offset bolt surrounds so you can actually make use of the adjustable locator.  Just have to use a different setup on the bolt sleeve shim.  I have  spare setup in the basement, I'll give it to you to play with when you come down for HPT's first round.
