Trying to get in on a couple of Thruxton cup races this year. Found some old posts (2006,2008)with good info, but nothing current:confused: Hoping to get in contact with a few guys that might be willing to help a thruxton rookie.

Thanks

Unless you like driving, you better get on the stick...both CA events are set for April. Do you have your roadracing license? If not, then make sure you do the Willow springs event so you can attend the track school the day before that event...no screwing around here since pre-registration closes on the 10th:

You also have to get the bike ready to go...which includes safety wiring it up, removing turn signals/taillight/sidestand/etc., and fitting race numbers. You also have to have leathers and proper helmet. I'd make sure I have pirelli sport demons or better for tires. Rule book is here:

The only other thing I can say is to enjoy yourself - especially during the first few events. The thruxton cup/transatlantic challenge events have historically been tight racing....

Appreciate the response.

Already signed up for the WillowSprings school. Waiting on my numbers. Been going through the rulebook with a fine tooth comb. All my gear/helmet is up to spec and race prep isn't really an issue.

One thats stumping me, how are guys safety wiring the foot brake pivot bolt? Rule book 9.4 (o)

Was still looking looking at which tires to run:confused: Ive only used stockers and the Avon Road Riders. Defiantly want something a little stickier. Most of the info for track tires I can find are the Avon a22/a23. So leaning that way. Thoughts? How many sets should I plan on going through for 2 race weekends? (Willow and Sonoma)

Wasn't expecting to hang with the big boys first time out, just want to finish upright:D

Not sure how the rear brake lever pivot is attached w/o looking at my bike.

You can through drill blind fasteners from flat to flat or drill straight through allen heads. For fasteners with exposed nuts (!!), you can angle drill across the flats, cotter pin through the nut/bolt when torqued to spec, or use a safety wire washer with the fold up ears on the nut side. The latter is a slick way to make quick work of wiring:

Also, it is way easier to drill the fasteners with a jig...you break way less bits that way.

Oh, and for tires, you should be okay with a set of sport demons. But if you want real race rubber, here's a reference for the avons:

http://www.triumphrat.net/club-cafe/8417-avon-race-tires-for-thruxton.html#post1252426

Front - AM22 110/80VB18
Rear - AM23 130/80VB17

Either set will last for the 2 race weekends you have planned...

I thought of going flat to flat but felt like the wire would either snap while tightening or not allow me to torque to spec.

Are you going to be out at either of the events?

I'd pull the fastener and grind a couple flats on it...then use a safety wire waster.

I sold my race bike in 2012 (a bmw R50/5) and have yet to get my crashed-out 350 Honda racer back on the track. Even when I did race, I pretty much stuck with regional events...Gratten, Gingerman, Road America, and Mid-Ohio. To top things off, my wife just had a hip replaced and will be having the second side done in about 3 weeks. So no travel away from home for me for a while...

Good luck and, above all, enjoy the rush.

Cheers,

--Rich

Was able to catch an edge on that narrow exposed part of the bolt and drill through. Thanks for your help. All the best to you and your wife. A hip surgery is a biggie.

Ill post up my results and some pictures after the race. Until then I have a lot of wrenching to do.:wacko
