Re: let the games begin - R69s engine rebuild

THE FINAL POST FOR THIS THREAD Well did the engine timing, fresh fuel etc. With fuel and ignition off I gave the old fella some kicks to get the oil pump at least primed. Ignition on, fuel on, 10 seconds on the carbs, two kicks and he was up and running. Carbs need to be fine tuned and there are oth...

Well getting close.....

Fuel lines, fuel, timing and connect generator, check the valve clearances and a general check over.

Who knows it might get a kick soon.

Re: Headlight bucket question

I would hazard a guess that this the shape and probably how it was cut.

Re: let the games begin - R69s engine rebuild

It is looking very nice!! Good job! James It has been a bit of a slog and not quite there yet. I have a complete head and rocker gear rebuild in the pipeline. However first up I am going to run the new pistons and bottom end and get that bedded in and then I will backtrack to do the top end. I actu...

Re: let the games begin - R69s engine rebuild

Heading for 14 months for this project and given other obligations it will be some time before I can carry on from here. However, the new pistons and barrels went on today and it was a boost to morale that things are progressing. A couple of pics to show the progress. MAL_1432.jpg MAL_1433.jpg MAL_1...

Re: let the games begin - R69s engine rebuild

A forced break while I did other projects, nothing to do with my old bikes. Finally got around to torquing down the flywheel. I followed the Barrington book and measured the runout at regular intervals. Final figure .04mm runout. A few new bits went into the clutch. Here is my setup for holding back...

Re: Fitting a side car to K1100LT - full fairing

I have never owned a K bike, always been a boxer fan. I rode his bike before the chair was fitted, lovely strong linear power delivery.
The ABS was working.
So all in all I think it is a good bike to pull a side car.

Re: Sidecar recommendations requested

I am not a sidecar man however some people are. My step son has one and we recently worked on changing it from a K100 to a K1100. His passion was very infectious. That said a K100 has a few more ponies than an R60 and that might limit the viability of your aspirations. Then if you have a dog and jus...

Re: Help ID this Bike

After more scrutiny, could this possibly be an R50S? The intake tubes/rubbers are right, as are all the other things (air cleaner, steering damper). We need the serial number! R50S numbers are 564001-565634. R69S serial numbers are 655001-666320. Dave Dave I think you have nailed it. Finned exhaust...

Re: Transmission fluid volume for 1956 R69?

Jake

All the old BM's I have anything to do with, the transmission level was at the bottom of the threads of the filler hole.

I would avoid filling past this point even if you have only put in 1.65 pints.

Others may have some other perspective.
