Ahhh...thank you Mr. Ty, faulty memory, yes.

Could be mistaken, but wasn't the '78 a 370? The '79's being a 400? Just curious, the collective will know.

I would second the Astro idea.

What would you like to know?

Don't recommend the Bultaco front hub. No surprise there... There is a 490 Maico with the KYB conventional setup around here, works pretty well.

Hey Davey, would you bring Roy to the phone? He could best answer this, he's seen all sides.

Interesting swingarm. Looks like the top shock mounts have been relocated also, and the "76 rear wheels have the brake hub on the left side, prompting that odd cable setup unique to them. Nice scoot. Have a pic with the side plates off? Side note: Is ... more »

Clear Channel steps up to the plate. Coors and Camel on board. Or Jam Sports.....that was good...

What a great project! I had a TR5 MX a while ago that was fun for TT's and scramble outings of the flat track sort. The thing I wanted to change most was the foot peg position. They were too far forward and high. But I find Rickman framed bikes the same ... more »

RPJ Performance. Has been quite good for us.

Normal?.....ahhh, no.

The "tall" foams we had at CEET had extra dimension in that area. If they have a tall foam, you can shape it to your preference.

Sinisalo worked well for me for years. Xtreme gear impressed as quality goods later on. Don't suppose either is readily available anymore. The original HRP chest protector was the most comfortable I ever raced with.

As is, where is?

Yeah, I know Rob, just day dreaming now. Still laugh to myself at the glee in Carla's voice as he was telling Soren and I his tale from Namur that year at the French MXdN. (Villars d Ecot ?) The quick beer stop....

Hmmm, always wanted to ride a 500GP at Namur.

5.10 x 18 is actually 110/100-18. We used the same mold (ex. say M22) at Bridgestone for both, eventually changing everything over to metric sizing with some exception. The 4.00 x 18 is the 100/100-18. The 4.10-18, a lower aspect ratio than 4.00 but ... more »

FWIW: I was there for the teardown of JMB and Jeff's bikes. For whatever reason (can't recall) Yamaha chose the Vegas round to ask for the inspection. The bikes were stripped to bare frames and swingarm. Both frames were stock yet looked very different ... more »
