Hi guys. A good mate of mine just dropped off my first K100 rt 1990 ex police bike. It has been half stripped down, all of the wiring harness unplugged but still on the bike. My first job will be to sort the wires out, clean all the plugs and reconnect the whole lot. It was apparently running well 2 years ago but used to cut out intermittently (sounded like a loose plug or wire I think). After that I plan to give it a few runs around the block after cleaning the tank out and start looking at where I will go from there. I will be lubing all splines and then I am not sure where to go next.

Good project Marc. It will be good in the end and there's plenty of knowledge on the forum to help you chew the tough bits.

Enjoy!!!!

Cheers

The four pin plug that resides under the right hand side of the petrol tank is a known source of problems. Mine was fine for twenty years and then started to cause problems even after using DeoxIT two part. I got cheesed off and replaced it with a four pin waterproof connector purchased from Jaycar.
Regards Martin.

likely new fuel pump and filter needed as well

had some success with white vinegar inside the tank to clean up the varnish coated in there ...more stuff needed for cleaning up dissolved rubber

good luck

Use it straight, and if you want to reuse it, filter it through a coffee or paint filter. Green Scotch scouring pads help.
And if you don't want Vegemite (black stuff) imbedded in your hands wear Nitrile gloves. Most of it will come free and be suspended in the vinegar. Until all traces of fuel have been purged do not use a vacuum cleaner on it. KABOOM.
Regards Martin.

I found metho (methylated spirits) excellent to remove disintergrated rubber from fuel pump dampener holder location and my hands ....be aware there is also a ridge that rubber gunk gets up under where the fuel dampener fits...i used a bent coat hanger and extendable small mirror to scrape mine out...as the old aussie song goes " oh have you ever been on the kerosene when the metho is getting down low" Very Happy

That's awesome. I wont even have to keep the metho in the fridge at this time of year Shamrock . Petrol removed the gunk from my hands in the end. I wil try to salvage the fuel pump and because it was working when parked up I think I might be able to sort it out.

After doing much much reading on the forum (thanks guys) I have found that a product called Sard wonder spray is great for removing the dreaded black goo. It is a stain remover for clothes but does a great job inside the tank. If I can get my fuel pump to work again I will post a how to. I have it full of sard ATM hoping it might free up. It kicks a little when I put power to it but still wont spin. I am hoping it will free up after a few days of soaking.

Sometimes alternating the polarity will free them up. As a last resort try briefly applying 18V and alternating polarity.

I have been hitting it for a fraction of a second with 24v, it is soaking again now but i bought 2 cheap ones from Aliexpress for about $55 delivered. If this one ever works ok I will keep it as a spare spare.

It is possible to take a fuel pump apart and fix it.

I have also freed a few of them up by letting them sit in a cup a Techron fuel system cleaner for a few days.
