Building a old school 350x TT racer.

[Mickey Dunlap]

Back in the day I never built a 350x full race bike, and as far as I know no one has since. Back then we didn't have low profile fenders, but now I do.

We didn't have a short track tank so you could really back it in to the corners.


I have just started building a short course tank based on the 85'-86' 250r tanks using the shrouds off a stock style tank to get more are to the 2 oil coolers.

This bike will be built to the rules for the Vintage class where we can only run up to .080 over in the stock cylinder. This will also be able to run in the new 200cc 2 stroke/ 350 4 stroke class, and the pro class if the customer wants to.

Getting the weight down is one of the goals which won't be much or easy because most of the weight is in the engine. I can get rid of 1st gear, the counter balancer, lighten and balance the crank and fly wheel, but other then that 10lbs I might cut the fins for more cooling mainly like the porky pine style cut I did on one of my 200x's.

I'm not sure where I'll end up on the swing are but I'm going to start with a plus 2 Cal-Fab and go from there. It will have a 10 inch front wheel and I'll just have to play with rear tires and sizes.

It's going to be a timely project over the winter months, but a fun one to see what a 350x can do.

sounds like it's going be a beast. I'll definitely be following.

I see you have one in the works too.

I never got to own a 350x but oddly enough i still have about 30 hours of time riding them as i was the test rider for two magazine tests of the 350x as well as i did the test riding for DG when they developed their pipe for it and i gotta say it really liked how the bike handled, its great straight line stability and it had a really comfortable seating position.

I bet a full race one will be a heck of a lot of fun, keep us posted on the build.

[Aulbaugh]

Yes sir I do, trying to it turn it into something again and learning alot in the process.

When I was racing oval track and TT down here in FL a few years ago, I raced against a guy with a pretty solidly built 350X and he did very, very well. I will post some pics when I am at home if I can stir a few up still.

THis bike was built by Walter - can't remember his last name and he was a member here back in the day but have not saw him or talked to him in probably 7-8 years. No hijack meant Mickey - just wanted to share these with some ideas and stuff to show his setup. On the oval tracks I could beat him pretty consistently, but there was this one kind of tight TT track we raced at (4th pic) and I always had a really hard time keeping up with him there. He definitely beat me more in that environment.

IIRC Tom Carlson raced a 350X at Pine Lake back in the day.

Digging the tank, excellent idea/work!

The rest is very cool too.

Great pics Billy. I know a lot of people have raced the 350x, I just never seen one set up like our bike were back in the day. I rode mine at Powroll just to train on something heavy so when I raced my 200x I would be strong enough to race hard for the whole race, but I couldn't ride it like my 200x. It doesn't do much good to have the HP of a bigger motor if it doesn't handle as good so you can fully use the power. The prototype 350x we first built with the xr350 RFVC motor was based on the 200x and had everything set up good, just never got to race it before Honda wanted it to send to Japan.



Now it's time to see if we can build it better, the motor is better then the RFVC 350.

Is there an update on the old school 350x TT racer building?
