GSX1100ET Sump

[bigyellowthing]

Hi All

Once again I seek your wisdom

The threads for my sump bolt are buggered. Anyone got a solution?

All advice gratefully accepted

Best

Get a new bolt ! :-p 

if it's the thread in the sump that's stripped find something longer as its threaded all the way through, a ham fisted mate over tightened his es750 sump I modded a spark plug ( same thread m14x1 ) worked fine

[micktodd]

As above  or could helicoil it  good video here

Remove sump, repair thread, refit sump with new drain plug and aluminium washer (the plugs only cost £3 or so from Suzuki and fit multiple models).

Yeah a helicoil is the way to go

Sorry  but don't bother with helicoils, Wurth Timesert is the way forward ... did mine 20 years ago and it is still fine

You can get a spark plug thread repair inset which is the same thread I used one on mine and it has been fine

But helicoils are still good & very common. Used in the aerospace industry for nearly all threaded holes in aluminium.

Or just find a slightly larger sump plug an tap it out to suit. No drama

Once again Old Skool is best.

Due to the design of the sump drain will drill and tap to next size. The casting has slots to allow oil drainage which would be blocked by inserts like helicoils and I'm a bit paranoid about plug failure leading to expensive and depressing consideration of parts prices..

Slot or not - makes no difference to oil draining, Its a big hole and oil comes out - end of story!

A helicoil will see out the life of the bike unless you are a gorilla with the spanners!

get a different sump plate on it

[bigyellowthing]

Does anyone have the tightening sequence for sump bolts?

[Gixer1460]

Alternate and diagonal - not critical, just don't over-tighten!

[bigyellowthing]

Wow that was quick.

Thanks for the info!
