Used to belong to a gentleman who was big on building and restoring.
Picked her up upon his departure, so not much is known.
Hoping someone can identify this as a kit or is it custom?
Thanks!

Looks like a custom application .
Only other R65 I've seen with a turbo, was a kit from Luftmeister, one of these was up for sale in Flagstaff, AZ about 10 years ago .
Is the bike in running condition .
-
Thanks Bob.
Not currently running. Engine turns over.
Going to get spark plugs tomorrow and strap a battery on to check.
Will keep fire extinguisher close.

if you have problems, not sure if a mechanic or a plumber would be your first stop ::) looks like a /6?.... good luck, would love to hear it run

Well, came back from Autozone with what I thought to be the correct spark plugs in 14mm diameter only to discover that they didn't fit!
The threads in the cylinder head look to be about 16 or 17mm. Will need to get my calipers from work and thread gauge to get the specs.
Can't find any other specifications on the net besides 14mm.
Plugs were NGK BP7ES p/n 1034

Run the serial number at Realoem.com and find out what bike you have. That front end doesn't look like a R65

Can't believe I hadn't thought about that!!!
1977 R100/7T
The seller told me it was a 1979 R65 and that's what I've been basing my research off. I had tried to get a carfax using the serial with no luck so gave up on that.
the plot thickens
-
So the R100 uses the same spark plugs in 14mm Diameter which will indicate that the existing heads are modified.

What a monster! Oh, just pickin' nits but the valve covers are on the wrong sides!
Good luck on sourcing the plugs. Maybe the seller could shed some light on the plugs or was his "departure" the more permanent type?

Permanent departure :(

No plugs in it when you brought it home?

None. The wiring is a birds nest.

That thing is an abortion, nothing more or less. With a single cylinder each feeding a turbo of that size if it works at all you will have truly massive lag, and probably not that much boost anyway.
I'd take it all off and see what you could get for it all from the car boys and then use the money to see if you can build a working motorcycle.
Oh, and your rocker covers are on the wrong sides, please correct.
Lastly, that does not appear to be an r65 to me, the front end is /7 at its newest and possibly a lot older. The front cover is also a generation older than an R65 and the cylinders suggest a long stroke engine - actual capacity unknown until you pop a head and measure the bore.

Thanks Tony.
I'll have to tear her apart this weekend and remove all the bits that aren't stock.
There's a Vetter Fairing that I also want to get rid of. Do people still want them?
Couldn't get an exact diameter of the spark plug holes, but its either a 16mm or 17mm 1.25 pitch. Couldn't locate any suitable plugs in that diameter during my brief search.
Anyone interested in following this adventure??
-
I'm very curious how you make out on this project. We have a section "Restoration Progress Logs" that would be perfect. Wonder if you could put a threaded insert in it and use a standard plug?
I was really hoping you could get it fired up with the turbos on it, would have been wild and a very unique sound!
Yes, people still use Vetter fairings.

On reflection my comment was perhaps a little more harsh than I intended. But it would seem that the original builder had not decided whether the carbs were going to be "suck through" or "blow through" and in any event there is no sign of any pipe work or trunking to effect either way of fitment.
Then there is the same problem that unless my aged eyes and the camera angle have defeated me, those two turbos are not a matched set - that means they will wind up at different rates and most probably have different mass flow capabilities, a problem that does not auger well for balancing the output of the cylinders.
The position of what I assume are oil collectors under the turbos is going to place serious restriction on lean angle, and as oil, like water, will not flow uphill I wonder how it was envisaged that the oil would return to the sump.
-
Maybe it was a project meant to go in a straight line...

Along with this bike came a r65 engine in parts. I've been more focused on the engine than the bike since I had the luxury of working inside.
The plan now is to finish where the last gentlemen left off so the bike can fulfill that one purpose. Will update once I get there!
