1976 MZ ISDT replica

 because i'm having a couple of wheels built with 17" aluminium rims it means i have to junk the standard belt-drive pulleys to enable us to run a conventional chain and sprockets, to get the front pulley off is a right job, you can't just drop it in gear and try and undo the retaining nut so i fitted the belt and tie-wrapped it to the pulley then dropped the open 'loop' end around my hydraulic work stand that the bike is standing on, i had to heat the nut up and borrow a 'jims' socket and bar off frenchy to shift it, they are bloody tight, must be hammered on at the factory with an air tool, i got chance to do a bit more on the bonny tank too, dangerous bought a tank repair kit which is similar to the one we used on the mz racer, [couldn't get the 'frost automative' kit as they are out of stock at the present time], washed the tank out with the marine cleaner and dropped a handful of old nuts and bolts into the filler cap and rolled the tank to knock the rust off the inside surfaces, [the bike had stood for a long time and condensation had made a real mess of the tank], i dropped the etching solution in and left that overnight, dangerous washed it out this morning and spent most of the evening drying out the tank with a heat gun ready for the sealant, we decided to leave this stage until tomorrow so we can make sure the tank is totally dry.
