Thanks!

Here are some photos of my 520 conversion. The rear sprocket is for a Suzuki DR 750 and the front sprocket is for various 90's Kawasakis. The chain is a very narrow d.i.d chain.

Front first. The sprocket has a section which is 2.6mm wider as shown here:

On the inside of the sprocket I have 6mm spacer similar to the one you see between the sprocket and the nut. The reason I have a spacer on the outside is because I'm missing the retainer washer. It's in the mail..  When I had it mounted like this the chain was to close to the rear tire. I flipped the front sprocket and put two 1.3mm washers behind the rear sprocket. Now there is 7mm clearance between chain and tire. I believe that is enough. I will at least try it for a while. With this configuration I can also use the original rear sprocket bolts.

Bruce comes home from the pub and sees Sheila watching Gordon Ramsay's F%*#ing cooking show on the telly.
Bruce says; "What are you watching that shit for? You can't cook to save your life!."
To which Sheila replies; "So what? You watch porn movies, donít you?"

Tried to make the tube at the end a little wider by hammering a stepped tube inside it. This clipped two of te rivets holding the muffler together. I drilled out the last one and took it apart.

Hammered lightly on the inner ring to set the pieces together.

Put it back together with new pop rivets. From now I'll treat the two parts as one and mask off the bend before I powdercoat the muffler.
