G'day folks, I'm an old new bloke here. Recently bought a derelict Montesa Cota 247 "Verion Ulf Karlsson" to repair/restore as a summer project. I'll be looking for parts over the next couple months, so hoping some on here may be able to help.
Been out of bikes for the last 25 (or so) years, but lots of mostly British bikes during late '50's through '60's. I had what I believe was the first TY250B into North Qld back in early '70's (don't remember exact date) also rode a '38 AJS250 in a couple trials.
First question, powder-coat or 2 pack for the frame when I get to it?
Cheers.

Welcome Daz... nice project.
I think most people would recommend Powder coat for the frame, -it tends to be harder and more durable - important for a dirt bike.
But be aware of oven heating issues involved with Powdercoating... eg the curing temps can destroy fibre S/A bushings and the like.
If you have the spray gear, 2K is ok, (but not a pleasant job to do- getting into all those nooks and crannies).

Thanks Jools, frame and rear forks will be completely stripped out (couple small repairs needed), so oven heat shouldn't be a problem.

Welcome OlDaz

Thanks David. Project seems to have started a bit earlier than expected. I found I needed to strip things down to find just what parts I need and need to repair. So it's stripped to bare frame and sand-blasted to A clean it up and B so I could do a full inspection. Just as well as I discovered frame cracks as well as missing mounting tabs all over the place. Cracks have been ground out, welded and reinforced, then stress relieved and all missing tabs replaced. A heap of parts has arrived from overseas and local supply, with more on the way. The bike was a lot worse than first thought as all "bits" were badly weather damaged from years of neglect and weather exposure. Hold up at the moment is the fork tubes, one is usable but the other needs full grind and hard chroming, so I need either one good second hand tube, or pack the pair off to Brisbane.
Anyone have a spare reasonable fork tube to suit??

Hi! Have you finished it?
