Suzuki 2 Strokes

Hi All,

I'm working on the restoration of a T250 and I'm looking for a solution to the stripped outside thread on the cylinder. When I don't use an exhaust gasket I can get a little bit of bite on the thread when attaching the exhausts, but that's not a long term solution.

Perhaps I have been searching using the wrong terminology but I can't find anything in the forums.

Any suggestions?

Thanks
Neil

Man, I don't know. I might take it to a machinist for advice.

A thread chaser might restore the threads to the point its workable again. A universal tool isn’t too expensive, but I would take the part to a shop that has experience with the tool.

Aluminium tape round the threads.

jabcb and Alan good suggestions!

I might try both. Get the thread cleaned up as much a possible, then a bit of tape.

Many thanks

I think its 48x1.5 thread if that fyi helps

njdmoto did aluminium tape work?
I've same problem. '71 T350.
Have talked to 2 machinists experienced with bikes & cars and both said it'd be over a day's labour for them: not economical.
Be glad to hear how you got on

willdesign,

I have just received the thread chaser, so ill let you know how It all goes.

If it doesn't work...fill the threads with JBWeld and rework the threads. I know it sounds crazy, but I did an experiment once where I drilled out an exhaust stud to 1/2" and filled it with JBWeld. After drying for a couple of days I tapped it to 8mm and put a long bolt into the hole. I tightened the bolt (using a torque wrench) and at 20 ft/lbs the bolt broke off. The threads held...
