AMF H-D SS250 + Honda FT500 + Honda CRM250AR....
« on: Aug 18, 2013, 22:31:04 »
Here are some shots of my other current project bike. I have always liked single thumpers - 2 stroke or 4 stroke. I had an original '76 AMF Harley-Davidson SST250 (air-cooled) which was a pretty crappy blke overall (poor quality parts / poor reliability etc.) and decided to make the bike I wanted when I was 18, but which wasn't available - a liquid-cooled 250cc AMF H-D SST250.

AMF H-D bailed on the 2 strokes in the late '70s without further development so I am making a 1 of none  H-D SST 250 LC from a '76 SS250 (fenders / frame / tank / seat / instruments / lights etc), Honda FT500 (forks / swingarm / steering head / disk brakes) and '96 Honda CRM250AR (ignition / engine / cooling system / harness etc). Here are some pics below. That way the thing will handle and stop correctly, with (hopefully) 2 x the HP on tap. CRM250AR has a 6-speed and powervalve.

The purists won't like it, but I don't really care. I am certainly interested in seeing other road-going single projects.

More to follow.

P.S. Don't lament the demise of the CRM250AR - it is in worse condition than it looks having stood outside since 2001.

Thanks very much. Just have to keep the momentum going now w/ work etc. I have another original bike on full restore -  a '78. Pretty bikes, but  with a very limited following now.

Make an interesting alternative.

I'm aboard!

This is going to be a helluva hot bike to be carrying a Harley badge.

It sure takes a lot longer than planned to get things done when you want to just move ahead  >:(.....anyway....

Spent more time measuring the AMF-HD frame against the CRM frame and components. I have to work out how to get the CRM engine monitoring system working with the AMF-HD airbox, as the CRM airbox is way too big.



I pulled all the electrics out and sorted out the main loom (I plan to do a straight swap of the CRM loom to ensure all the sensors / solenoids are powered.  I did manage to get bad welds redone and gussets welded in for better rigidity, with patterns taken from the later Cagiva SST frame. I am going to have the welds smoothed and redone to be sure there are no bad welds.



Next, the engine / cooling system will be removed and matched up to the frame.



The best part today was when I removed the airbox to check the condition of the carb intake......



More later.

Out of curiosity - since you're cutting everything up anyway, why not build around the frame that already fits the motor?
unplug the connectors from the harness and multimeter the shit out of them
