Rear axle nut

I need a rear axle nut for a narrow case. I swear this is 15mm. Have searched many fastner suppliers but no one show. I have a 14 and 16mm, too big & too small. Anybody know where to find, appears to be 15mm x 1.25 pitch.

Re: 520 chain on a 250

Thanks for the input guy's. Probaly stick with the 428 and replace it every couple years. Steve, this bike (flat track frame) carries a lot of chain. Can't remember the link count but never found it "boxed". Last one I got from A&A Racing they cut off a spool.

520 chain on a 250

Someone told me that there is a easy way to convert a 250 motor from 428 to 520 chain. They said is a countershaft sprocket off a "Honda Motocross bike" that has the exact same spline and "may have to shorten it a little". Has anyone done this, know what he is talking about? Using on a flat track bi...

Shifter eccentric adjustment

Down below the shifter there is the locknut with adjusting screw. I have heard it called "eccentric adjuster" and that you can adjust it if shifting problems. If I just ride it like a street bike it shifts fine. But, in race condition at hi rev & shifting fast i often blow the 2nd-3rd shift, wind up...

Something completly different

http://i1104.photobucket.com/albums/h325/georgep61/Ducati/000_0418.jpg 1965 Swanson/Ducati 250 Shorttracker. A couple years ago I was at a flat track race in WI and saw they have an active "250 classic" class. Picked up this bike on e-bay. It is a Duc 250 in a custom made "Swanson" dirt track frame...

When they went to electronic you have to have a good battery. Get a tender and use it. There is no excuse for it to hard start or kick back. Malcome did my 250 flat track motor, ditched the points. Stout motor. I don't know where you are located but Syd's can help. I run the Amal just fine (for vint...

I have seen the scrambler frame used effictively (sp?) as a flat-tracker. There should be AHRMA races in your area and if ride road race it should be a natural for you. What is there looks clean & solid. Good Luck!

You fill with fluid connect it to what is normally the bleeder screw, open the master cyl. and "push" the new fluid up towards th...

Ducati 250 dirt tracker

Hi guys! This is a neat site. I live in the Upper Penninsula of Michigan. We ice-race in the winter and I am a big fan of MotoGP and WSBK. Have a 1966 Duc 250 motor in a custom built dirt-track frame, called a "Swanson frame". I understand there were 12 of these built in the early 1970's. Had it for...
