Hi My name is Billy and I live in Gloucester UK. I am working my way through a restore the aim is to get it back to resemble when it left the factory in 1975, well trying to.
Ok so I bought this over a year ago. Its missing a few bits like wrong handle bars front reflectors, steering damper, grab rail and it has a 130 rear tyre which rubs the swing arm all the chrome has been painted silver, badly. Also some nasty rattle can red paint on the tank and panels. The tank was treated with I think a substance called Kreem ?? (old post on here) this was an inch deep at the bottom and falling apart on the sides.
That's a nice project you have there. A fellow Glouc's Suzuki maestro (Paul Cann) just won Best in Show at Stafford with a T305 so you are in good company:
Both he and myself get a lot of work done at Reality Motorworks in Bristol. Worth a shout for a bunch of restoration services.
You have a pretty good basis for a sound machine Billy, my 500 was in a rather more shabby state when I got it. The hard to find mudguards look good and can be re-chromed (although chroming is pretty expensive these days). There are good ethanol resistant tank sealers these days but if you are stripping the tank for paint that would be the time to make any repairs (welding the leaks etc.).
I have never had the need to strip old tank sealant, but, I know a man who will probably have the answer. I'll ask him next time I see him and get back to you.
Acetone has been advised, have you tried that yet?. Followed by Caswell's tank sealant which is ethanol resistant (can't say "ethanol proof" as nothing is perfect).
I have had success with Acetone...Takes some time to work however. My painter has also used paint gun cleaner very effectively. As for tank sealers, Caswell is the only one I trust.
Tried MEK, and the Acetone was in there for weeks. hey ho
i have started on the engine
thought i would do some tests, compression was 135 and 140 the did a leak down to check the seals so block off exhaust and intake and pump up to 4.5 psi
stayed there for 3-4 mins so i presume the seals are fine so off with the heads and jugs re-bore to +1
