Yamaha HL500, Ideas and Variations of Building one.

Firko Mike is reffering to Marcs post 

Heres the real dealio ..... good thing  about the PE swingarm is it looks like the original.... pretty angry looking Lesso in the background

Hi Crankpin,

What frame are you using? is it a Husky frame, what size/model Husky, and year is it from?

Thanks

I think and correct me if Im wrong. Husky pre78 frame is also longer from steering tube to swingarm axle, so with Rm swing you end up lot longer wheelbase than original.

Heres my start

So if you use a std frame does that still make it an HL 

I think people get a little hung up on the HL thing, the TT motor has been fitted to a number of frames, Montesa, Maico, YZ even. The 500 motor is reliable, easliy available big 500, screaming out for better suspension and frame and the HL is the most successful but just one example of TT specials. None of which are probably perfect but the TT500 was always a bike that was a work in progress, with very few staying standard ..... because the original TT had a more than a few areas that could be improved upon

It's a lot of a bitsa. You know the script, 9 new handles and 3 new heads, same hammer.

The Husky parts I've used were from a 82 250CR.

My C&J replica. Note not a HL.

Refreshingly different from grist of the mill HL reps .

Standard TT500 won US 4 stroke national in 1980, Goat Brekker from vague memory. Anyway a stock bike is probably ideal for guys who are a little lacking in inside leg measurement.

I made this


From this (-78 husky)

Very Nice. I am a big four stroke fan.

Hi Ola,

you did an awesome job on your frame and found a new use for a rusty fork leg  ..... I have simlar project coming up but trying to work out how to use White Brothers swingarm with full widh spindle in it, may  build shorter oil tank.

And ended up with this

HL, C&J, DMR, Redline, Cheney, Curtis, Pro-Fab, KR, Hindall and a few more all made variations on the XT/TT Yamaha theme. May they all exist in harmony as examples of the different theories on what was felt to be needed to improve the XT/TT at the time. With the 30 years of evolving technology we have at hand today, the TT fan can pick and choose the exact set up he wants, whether it be stocker, tricked up stocker or custom framed special. Along with the XL Honda and DT1 Yamaha, the TT Yamaha was arguably the most hot rodded bike in our sports history.

Also the TT/XT/SR engine is basically still in production ( Yamaha Japan's biggest selling road bike is SR400) so unlike the XL and DT or most of the older 2 stroke MXers you have 100% parts availability from your friendly local Yamaha dealer. Plus a number of after market makers still churning out cams, pistons etc. I really like the XL / XR engines for being compact but I don't think they hang together like a TT motor can.
