Re: Very off-topic pet-seal question!

Hi Mark, I used a product called petseal remover, I got it off e bay, it turned the petseal into small grains like sand which were easily washed out. Following that I did the electrolytic process to get rid of rust, then recoated with POR21 from frost automotive.

Re: Gearbox sprocket?

Just check that the chain doesnt hit the gearbox casing, especially if you are going to run o ring chain. Also check the chain allignment

Re: Front forks

I did a similar thing when I fitted a set of yamaha 250 forks to a 650 bsa a few years ago, I ended up getting a set of springs made 25% stronger than standard, I used a company called active springs in Studley, Warickshire, from memory they were quite cheap.

Re: what kind of welding?

The type of welding is not as important as carefully considered mount design, they need to be designed to minimise localised stress which could lead to failure. Another important factor is the quality of the weld, correctly welded MMA could be better than badly performed TIG which should be theoreti...

Re: Kubota Z482 Engine - Low compression.

Sorry about your tale of woe. I mated a Kubota d950 to a bmw clutch and orriginally thought the holes matched, only to find that one of the Kubota holes is asymetric (easily fixed with a bt of filing of the clutch).

Re: Back (again!)

Youve already got a 5 speed gearbox, just machine the MZ engine off it! That should also sort out final drive allignment if you use the MZ frame, you just need to make front downtubes and cradle and sort out primary drive. It might be possible to get the MZ clutch onto the diesel engine and get it t...

The pic where it is loosly slid over the splines on the gearbox,not the crank, the bit that is turned down goes in the centre of the crank, the bottom pic shows the adapter in the crank, the hole where the gearbox splines fit can be seen.

Re: primary drive options from a tapered shaft

No idea of the sizes but I do remember a MZ ETZ250 had a clutch mounted on a taper on the end of the crank, maybe you could have your crank ground down to match the clutch?

Re: birdbrained idea continued, but very slowly.

Hi mate, which clutch are you using? BMW have a heavy (early) and a light (later) clutch. Ive mated a heavy one to my kubota d950 and found that the flywheel is only just heavy enough, I would think it would stall when coming off the throttle with a lighter clutch.

Re: birdbrained idea continued

Yes, your ratio is 3.36:1 which is less than the r100rs box at 3:1, if you were to change boxes you could increase your overall ratio by just over 11%. I picked up my box off ebay for £30, but they usually go for around £100.
