I just picked up a K LT and noticed more vibration than what I get when riding other's K's. Also the tank leaks fuel (I knew about it when I bought it). I traced out the leaks in the tank, and they were most likely caused by the vibes, but what is causing the vibes???

Welcome Dayrider! Soon you'll have a K11OG sticker for that bike!

There is a thread here somewhere for a guy that restores tanks. People have been happy with the results at a reasonable price.

Does it vibrate or buzz? What rpm? Not that this will help me answer your question but it will help someone who knows what he's doing.

I had my tank coated and sealed by Eppa Wimbash in Richmond, VA. He charged me $80 for the work and I payed shipping to and from (I sent a prepaid bill of lading with the tank for the return shipping.) The tank doesn't weigh much, but it's large, so they get you with the "dim" weight. I think it cost about as much to ship it there and back as the actual work did.

No leaks and I got to keep my original tank which looked great on the outside.

The leaks are usually from water accumlating in the side lower corners and causing corrosion (not rust) there. Mine was a tiny hole, but it was getting bigger.

PM me and I can send you his email.

$80 sounds like a good deal to me.

I've shipped a few K tanks in my day. Shipping it FedEx will most likely be cheapest. Keep the box size to a minimum or you'll get hit with oversized box charges.

My plan is to gut the tank and kreem coat it.
As far as the vibrations... I haven't had it long enough (I've already started to disassemble and clean/lubricate everything) to say much more than it made my feet numb during the 90 mile ride home. The tank leaks around the welded tab on one side and a small nic on the other side.

Hi, Dayrider,
I'm not saying it can't be done and I'm not saying not to do it. Just remember, you aren't working with a steel airhead tank with only one or two petcock openings. You have a fuel pump, a fuel level sender, a filter, fuel lines and an opening for the electrical connections. The Kreem cannot foul any of those. Make sure you (or whomever is doing the work) KNOW what you are doing and take whatever precautions so that things work the way they are supposed to work after the Kreem process is completed. Good Luck!

Update:
I have completed half of my fix it plan with the tank.... It is sealed from the outside with comerical gas tank repair kit (works fine no leaks) and since it is covered by the heat insulation the repair isn't noticeable.
I now need some power windsheild bits ( the flexible lift rod from the motor to the left slide) im me if you've got one...

(sorry for digging up another old thread, but i figured better than making a new one to rehash the same thing.)

>but with the vibration i mentioned above that moves through the bike be helped by that? what could cause that? anyone ever heard of that before?

The exhaust bolts to the left rear frame through a rubber mount. If this rubber bushing is hardened and cracked, as it was on my '95 RS, it can transfer vibration into the frame. A new one is only a few dollars online from Bob's BMW. You can look it up on their online parts microfiche.

TB sync all the time, While your at it raise the revs with the throttle and check that the butterflys are still sync'd, I noticed mine were out while doing the TB sync, not alot but 1&2 were higher vac than 3&4 meaning that 3&4 were at a higher throttle setting and doing more work. I did mine and it made all the difference.
