Petrol tank repair

Hi. New to site, restoring a 1977 400f. Not been on the road since 92 the tank has 3/4 very small rust holes on the underside. I've done a temporary repair using tank seal from Halfords but wondered what options there are for a more permananent repair? Could anyone also recommend someone to respray and fit decals to said tank, preferably in East Midlands area?

Hi, and welcome to the madhouse. Brazing or welding is a far more enduring repair, bur make sure whoever does it is familiar with motorcycle fuel tanks. A member on here's local garage offered to do it, but destroyed the tank and nearly blew themselves up as they didn't make sure it was completely clear of residual fumes, and left the filler cap on when they started welding! If your not too fussed about originality, Dave Silver Spares sell replica tanks for a reasonable price.

The bottom of the tank gets thin all over.  There's no point in repairing each pin hole as more will soon appear.  Furthermore,  the rust dust will block the fuel filter.  It's a better repair to cut the affected parts out, both sides, and weld in new sections.  As Hairy has said, find an expert to do the job.  As you may have guessed,  I've had this bother before.

look up MTS motorcycle tank repairs.  not cheap at  £50/hour but worth it.

Welcome to the forum. If it were me, I would buy a new tank.
