The one thing I'm looking forward to when/if ITSA comes out West is the classes. My M49 is in the Modern Classic AHRMA class which puts it at a substantial disadvantage against the later bikes. Since Bultacos are difficult to define by model year, where is the actual break between Historic and Pre-Historic by Model Number? Is it M49/M80 or M80/M91? The bad thing about the ITSA classes is poor support for the really old bikes (pre-65) which should not be in the same class as an early 70s trials bike. But this just reflects ITSA focus towards the newer bikes.

If you are hearing a complaint "way too often" it *might* be time to find out why... I have not been to an ITSA event but it would be interesting to see how they balance the different classes and rider levels. There a bit of difference between an early Bultaco and a late Fantic. Of course one could argue that there is even more difference between the rigid BSA and a late Bultaco you'll see at an AHRMA event... The reason ITSA isn't strong in the PNW is that we (fortunately) have some very, very good vintage trials here. And some very dedicated trials folks. If that should falter I would expect ITSA to move in rapidly. And what if the section is too hard for a novice rider on a vintage bike? Not much to do then. No offense but right now I'm already paying dues to a couple trials clubs. Like I said if things change in this area I'll be the first to sign up and get ITSA going, but until then I'll stick it out.

Vintage Bike Racing There is an ongoing discuss about this issue and others on this forum. (They rarely bring up trials unless I do there so I hope it's not a conflict posting this link). ITSA hasn't made it's way all the West Coast yet so AHRMA is all we have. With nearly 100 riders at the last Chehalis National it's doing ok. The one complaint I've heard from some people is that ITSA is too hard. That is the challenge when you mix later bikes with vintage ones. It's a similar issue when trying to mix vintage and post-vintage (1975-on) mx.

Why do math. It's HARD.

Yup. M137. Might want to wait for a Sherpa or different Alpina.

Correct me if I'm wrong but I believe the earlier Alpinas were much closer to the Sherpa Ts.

About all I'd do it put the narrower tank/seat on and some good tires (assuming you've removed all the lights and crap).

There was a thread on an electric trials bike here a while ago.

Here's the link I finally found for the instructions on posting. Let me know if you have any questions. Here's the PDF file (converted). Plus a smaller pic for reference. Brake_bracket_TY350.pdf

You have to split the crankcases to change the seals or just look at the kickstart stop?

Yeah, that's pretty standard. Crank seals are the first thing you change when you get an old two stroke. Let's you see how things inside are put together too. Or how badly the PO put them back together.

Do you have a picture of the filter as "Miller filter" is a little generic?

Host the pictures on somewhere like Photobucket or Flicker and then post them here.

I searched hi and lo for the post. Can't seem to find it. Went back to 2003. Saw some post where you mention posting and went back from there.

Probably custom design, although they look like something off a mid-60s Japanese bike. You can always try Clarke and if you don't see what they have on their site, they probably have something "in the back".

Did they make 441 prior to 65? Or can you get away with "like design"?

I saw a TY250 with a TY80 tank on it at Donner this year. Did a double take cuz it looked so funny.

I sent a supportive email to all the relevant folks. It should have gotten forwarded to Ed. There has been some discussions on the future of AHRMA here: Vintage Bike Racing The talk has been centered around the Road Racing and Dirt Racing crowds, as that's where the money is in AHRMA. But it could have significant impacts on trials. After looking at the class structures of ITSA, I may prefer them to AHRMA. At least my poor old M49 won't have to go against 199s and such.

There's enough pictures of KTs on the web (heck on this site alone) to compare to.

What was the turn out for the trials? Pretty rough with one of the riders dying out there. I'm not sure if I would have continued or not.

Well, if you plan on riding trials with it and it's a stock Cub, figure a lot more to convert. If it's already set up for trials, well, all the better. If it's one of those hyper-light trick Cubs then it's probably a good deal. So depending on how bad you want one...

are they listing a price? is it set up for trials now?

I think in the Borne thread a while ago someone posted a YouTube link to that scene. Back to Bond, I recall that Mr. Craig was having problem driving the Aston Martin as he didn't know how to drive a stick. Now he's riding a bike. No bad.

It'll burn a hole in the tank, don't ask me how I know... I used pipe insulation and that worked great.
