motor has compression, spark, gets fuel, but doesnt want to run. probably a good thing. it really should be torn down and inspected before being returned to its former glory.

is that an H&S or pauter cylinder?

Great find. Thanks for not telling us how little you paid for it. There are sure some awsome trikes around your area. There is a rd 350 sand drag trike near you for sale for cheap. It was in some 3 wheeler mags in 80 or 81. Very nice find are you going to do a full resto or just as little as it needs to run it. I love the early race stuff. 90's and 1st gen R's are the roots of atv racing.

Between Shortline and Veal. They will tell you every part on her ! I would need to go study to do so. I can certainly see that someone spent a TON of time and money trying to get her to the front of the pack back in the day !!! Very cool piece!

i like my stuff fully functional, but cosmetics arent too important. that being said it'll get a nice spray from the rattle and a chaser of new parts like bearings and cables. motor internals will be torn down, cleaned, inspected, and reassembled. seat will get a custom old school cover. ill likely need a new seat pan

ive seen that Marty Smith RD bike advertised for 2 years now. not consecutively for 2 years but every few months. actually when he first advertised it, he had only dont $750 in motor work and only wanted $900 for the whole thing. now somehow the bike hasnt changed, but he spent another $150 on motor work and wants another $600. if you search my old threads you'll actually find where i posted that bike for sale when it was first advertised. i saved the orig text from the ad. some people...

I think I might have to steal that from you Manbearpig! Nice find!

[lardog]

That is a H&S cylinder .

[HappyTrail]

Wow! Look at that diamond in the ruff! Looks like alot of cc's there. Can't wait to see it's progress.

[Big G]

Is that the oil cooler in front of the cylinder? Never seen one before...how do they work?

[yaegerb]

So, fourth picture down on the topside valve cover....Is that an aftermarket compression release valve or where another hose goes for the oil cooler?

Trick piece for sure. You cali guys suck

[shortline10]

Case breather in the tappet cover .... Must be a BIG cc motor .
You need to build one of these Brendan

Awesome find BTW Manbearpig

Indeed Mike. Someday I think I will just buy one of your finished beauties

[shortline10]

My guess with no spacer plate would be 61mm bore X 58mm stroker = 169.50cc could be a short stroker at 54mm but for your area its gota be a 58mm .

that is pretty cool man! and thats another thing I hate about you west coasters, you all spray your bikes and they dont look like complete sh!t after the first ride because you ride in forgiving conditions lol spray a bike around here and the conditions will strip it in no time. I have seen a bunch on here from Cali/AZ spray their bikes and they look great ride after ride. Meanwhile my powdercoat is starting to look a little rough hahaha

[zsoccerdude17]

an Paul!! You always get the nice stuff!! Great find!! Jason, you gotta have the special touch to get the paint to stay
