In that color scheme, they just look fast.

I was playing around with MSpaint and like this colour setup for the old GS PD



Like it with the black wheels
Please note: This is just a mock up.

Damn you're good with MS paint. That program is a mockery of a sham. I like the black and red a lot, but it needs just a touch of white somewhere.

You sure about that, Stephen?
Every 1000cc mono-boxer, RT or RS I've seen had a 33/11 or 3.00:1 final drive. 32/10 or 3.20:1 sounds more like an R80 piece.

Interesting mod. Have you compared the circumference of the 18" tire with the 17"? ie: Does this afford any appreciably taller gearing?

We're having a Tech Day on June 6th in Ancaster. Come on out if you're able. Check the Canada RF for details.

You might be right, it could have been originally from a nekkid R80 Monolever, the R80RT had a 37/11. I didn't keep the transaction details from my original buy in Europe, dang. I was offered a 32:10 from a US breaker yard, supposedly from a Monolever R100RT.

The 18" has the greater circumference. A lot greater since I had to cut off one inch of the undertranny canister. Whether that "affords" taller gearing I don't know. I choose to experiment with taller gearings for another reason: having a 1000cc engine in there and expecting a lot more long distance street riding in the next 2-3yrs I aimed at getting rpm down and mileage up for 70-80mph cruising speeds using the HPN long 5th + taller gearing. I have all three final drives (37/11, 32/10 and 33/11) and will do one season each to figure out what fits best. The 33/11 on my UK spedc'ed R100T was a very good setup so I think I'll end up with that eventually.

You're doing some interesting work here, Stephen. And, imho, addressing some of the GS's major weaknesses.

1. The Para-Lever rear suspension works okay when carving up paved twisties, but it's terrible over corduroy road surfaces. Same thing on the Oilhead para-levers. The old twin shock boxers work far better in those situations. I expect the mono-lever boxers work better there, too.

2. A healthy 1000cc motor can easily pull more than the stock 34/11 3.09:1 gears with the stock 17" rear wheel.

If you don't mind, a couple of quick questions:
1. Rear rim width and tire size?
2. Inflated OD of the rear wheel/tire combo?

Thanks.

The rim is a stock BMW (front R100R) 2.50 x 18 rim:





Tire is a Kenda 270 sized 4.50-18, the inflated OD of rim/tyre combo with 32PSI is approx. 680mm (26.8")
