Hi,
Does anyone know if the k1100 fuel tank will fit the k100?. Mine is leaking in the usual place, and wondered what my options are.
Thanks
John

I know for certain it wont fit early K100 with the bolted down tank as the connections etc are different.

Not sure about later8 valve K100or 16 valve K100s.

I see from your profile yours is an '87. I'm not sure when the change from the bolted tank took place but i think yours is the later type which should be interchangeable. The tank repair is not difficult, why change it? Use the search tab on the portal page to search and there are many expales of repairs and suitable materials.

If you have a good aluminium welder around...they can be welded....mine has been welded.

Agree with Ainsjac, I'm another who went down the route of having the tank leak repaired by aluminium welding rather than an epoxy fix. I felt it was more permanent if you can find someone to do it.

Cheers

Thanks for the replies,
I've already repaired it once with tank puttyand its leaked again (about a year later) I'll investigate and see if its from the same place or somewhere new. I'll also check the posts on repair you mention.
Thanks again
John

If anyone is stuck for alloy welding you can go to your local college and ask the welding instructor if they would let their experienced welders do the work for you, most instructors allow this as its goes towards the trainee's grades. I have done this when I have had no welder and have had bike frames fixed and all kinds. Could be worth a thought. you could take the welders name for future work as well.

thanks all,
ive sourced a k1100 tank,which fits,but on close inspection it also has 3 small pin holes.the seller did say that if any holes were present he could get it repaired at his place of work.so i will probably do that.bit o a hassle to drive back there to drop off and pick up but its in better condition than my original tank (rot wise).quite fancy the idea of polishing it up and leaving it in its natural alloy state so welding would look better than sticking a blob of filler on it i suppose

I'm that fed up with tanks leaking I've bought a welding set,Argon bottle and taught myself to ally weld.
It comes in handy.

I'd be disappointed if a K tank didn't leak!!
