1974 R90S Transmission question

I recently bought a 74 R90S in rough but restorable shape. When I looked at photos of these machines on various websites, they all had kickstart transmissions. Mine does not. Is this the wrong trans, or are these available both ways? If wrong, would anyone know how tho either convert, or find a used one?

I'm not certain on the availability of the kickstart, but I would guess it was phase out over time and was also an option. From what I've heard, the kickstart on these machines left quite a bit to be desired. It was functional, but just... It seems the kickstart is best left for those dire situations when the electric start didn't work. Even then, you could bump start the bike... Duane Ausherman has info on the kick start workings here:

Hi I have a 1974 dt 360s that needs a new RH front fork and as the DT 175 runs the same size 21 inch front wheel as the dt 175s does that mean the front forks are interchangeable ? I have only been able to...

no not really,the diameter of the fork tubes are probably different,maybe a dt 400 would be closer,replace them in pairs,dont replace only 1,the spring rate & dampening is different,try junk yards in your area,get a complete front end from a dt 400,it should fit.

The last Harley-Davidson motorcycle to use the 1 up - 3 down was the 1973-74 Sprints. The U.S. law was adopted in 1974 effective with the 1975 and later models that required all motorcycles to shift on the left side and be in a 1 down and 3 or 4 up pattern. Today, they are still 1 down and the rest up. How many up is dependant on the year model. The last year for right side shift Sportsters was 1974. In 1975 and 1976, they put this funky crossover linkage under the bike to convert the right side shift transmission to a left side shift. Then, in 1977, Harley modified the cases and the transmission to be a true left side shift. Man, that was a long time ago. Means I'm old and I might not be totally correct but close enough.

I'm trying to adjust my DellOrto carbs on my BMW R90S.

Surely it is just a matter of adjusting the idle - or is that what you are after? A manual for the PHM?

1. Frame. If you've owned K-bikes, you know that nothing flexes between the steering head and the swingarm pivot. Very stable. Not so on BMW airheads, with their double-cradle steel tube frames, which earned airheads (like the R90S) the nickname Gummikuh (rubber cow). 2. Brakes. The R90S has 70s-era brakes. Not so good by comparison to late 80s-early 90s K standards. Many of the Ks also have ABS. Not so the R90S. 3. Engine: K-bikes engines are liquid-cooled fuel injected, computer controlled, and exhaust catalyzed. The R90S, like other airheads, is carbureted and air-cooled. Stay out of traffic jams on the highways, or pull over and shut it off. 4. Tires: The post-90 K-R bikes models have radial tires. I've found the R90S, like the KRT/LT models, to feel somewhat tall with its bias ply tires. That said, several years back I bought an R100RS just to own one, and to understand the experience was. Didn't hold a candle to a KRS in terms of performance, but had a certain heritage-appeal.
