3 scrap cranks later... I've sent the original crank away to have all the main bearings replaced, dynamically balanced, conrods and pistons weight matched and then welded.


Decided to use one of the other blocks to try the 90 carbs on. Had to countersink the top screws on the bottom 2 carbs. Took the 165 main jets out of the 70 carbs and put them in the 90 carbs.


The throttle and choke linkages from the 70 carbs all seem to work on the 90 ones.

The throttle cam isn't perfect, rubs on the metal part of the carbs a wee bit, going to wait until it's back together and see how it goes.
Think I'm going to have to cut a hole in the tray for the bigger bowls on the carbs.

Also put the CCM reeds on this one, removed the stops as well.

Once you get the engine back together get the Enduro cowl painted and some new decals on it. Looks sorry for itself.

Yeh it's not looking too good just now! The old decals are pretty well stuck on there, I was looking at maybe vinyl wrapping it instead of paint

Hairdryer and patience. Job done. You can remove adhesive residue with a little petrol or rubbing alcohol.

Not sure how vinyl wrap would work on a cowl given the edges and angles.

Was at it for an hour with a heat gun and nail varnish remover (meant to be good for this sort of thing), removed about a square inch!

Wonder if the whole thing has been given a coat of lacquer in a previous life? Rotary sander would be my weapon of choice.

possibly, I'll give that a go and see how I get on.

Latest prop, got this from America, Yamaha 15G Semi-Cleaver. Should make a good all round/surf prop.
I wouldn't mind a 16G of the same prop, I think the 70 will spin that no bother

When I resprayed my tohastu cowling I just used an electric sander.

Left the decals on and sanded them off.

You have to sacrifice a sanding pad for the decals but it was pretty easy! Click image for larger version
