The 520 conversion would make live very easy as I could machine the front sprocket from 5/16 to 1/4" and everything else would bolt on
I just need tires and a chain now, sprockets are ordered
Got a good used set of tires from the jumbo bin at a local bike shop, mint. Just need a chain now, got the DR250 rear sprocket and a new TS front witch I will deal to tonight.
Yes 18” and 21” I was going to get some of those oven number boards unless I can find the TM side covers, I had a go at the front sprocket last night But my lathe is too worn and chatters from the sprocket teeth so I will have to take it to my friends work and he can do it on a better lathe and they have ceramic inserts witch are good for hard steel.
not sure who makes them

if you heat the sprocket to cherry red. allow to cool slowly it should be soft.
Then after you have machined it, then re-heat to cherry red an quench in some dirty old black engine oil to re case harden.

I am just going to take the sprocket to my friends shop, if I try to re harden it I reckon I will screw it up and the teeth with snap off, they would be tempered just on the teeth.
its not super hard as I can cut it with a HSS tool but my lathe is like from 1937 or something like that, I dont think I can do anything on the bike for a bit, run out of funds, got an old Yamaha TT600 Tenere to rewire and sort for a guy to.
nah heat to cherry red and plunge in dirty oil (the oil has to be old crudey suff that where the carbon is) it will not turn out too brittle unless you plunge it into water
you cant really mess it up unless you melt the sprocket in a forge at 2000 deg c or you dont expect the oil to catch fire panic and kick it over or such like.
just have something to put over the tin of oil you use to put out the fire and only heat to red. Not until its a melted puddle.
The bike looks really neat far better than i expected it to look.
I might have some CR125M side-covers or similar. if i raid the old mans they are kind of the right shape.
just the heat from grinding or machining the factory hardened sprocket will likely destroy and cut through the factory heat treatment anyway.

Turned the sprocket down today with a ceramic tip no problems, just used a high speed, lots of sparks.
