Good plan :) Also there is some conflicting info as to what is proper idle speed for a K75, some say it is 1000RPM or even lower, but 1200RPM seems to be the best, at least on my bike. 1000RPM is OK-ish, but higher RPM makes for a steadier idle, also bike picks up speed better, no hesitation, etc. At 8-900RPM my battery light starts to glow, so I have it set at 1200, and I am happy with that.... Maybe try this higher setting, and see what it does to your idle...
good idea, the idle is low, under 1000. May screw the idle bolt down a bit. I did read on here somewhere that the light switch for the Ďchokeí at the end of the fuel bar can stick and cause the throttle not to close down properly?

Hi, I used a fuel cleaner in mine for the first 1000 miles.  Seemed to run much better after a while.

Ok. Thanks. I went for a 100 mile ride on Sunday, and it ran fine. The fuel system cleaner canít hurt, so I will give it a go. Thank you.

It definitely won't hurt. Should clean out the injectors and fuel pipes.

the injectors have been professionally cleaned, and I fitted new fuel pipes.

Rear shock seines up. Got a new YSS on there now. Recommend it for a good cheap shock.

Ok. Replaced the splines on the prop shaft 1050 miles ago. They are now already worn!  It sure they were made of hardened Steel like the original set.

Send a picture to whoever you purchased the splines off, and see what they say.

If you replaced the spline collar without replacing the worn FD pinion you were asking for trouble.

Yes. I did earlier. Thing is, the replacement splines werenít made of hardened steel like originals are.In my opinion, they should have lasted longer regardless of the final drive spline condition.

Ok. Looking for a good final drive now, and do it all over again over the winter. I want to get this drive shaft issue sorted, as I want to do a fair few miles on the bike next year around Cornwall, as my disabled brother is moving there to be closer to his new born grandchildren. The bike is my transport of choice, as I need to keep the miles down on my work van.
The K75c is great to ride,so easy, too, but I canít have the drive components let me down. Iím a bit short of cash at the moment, as winter is looming up and my work as a gardener, will start to get scarce.

Guess you proved replacement spline collar made of recycled Datsun bumper poorly heat treated is a no go

Certainly looks that way! However, I did email the company (Motobins),where I  bought them from, and they said they have sold loads and have had no complaints. But I could have had a Ďbadí set, apparently. So they are sending me another one, free.
I also have managed to find and purchase another final drive in California on fleabay, which should be here near the end of this month. £249.00 with shipping, from a 35,000 mile bike.($303.00).
The new splines look a lighter colour than ones that I have seen on other shafts, so I am wondering if they are a softer metal that could be hardened with heat and quashing in oil.

The new set that I bought V a library pic of an original set. The original look much darker, ie denser, stronger material

The first set probably were parkerized or some such to prevent corrosion while the replacement wasn't.

I would contact Motobins for heat treat instructions.

Emailed Motobins. They say they donít know of any Ďhardeningí process involved with these.

The edge of a metal file will easily cut a notch in an unhardened part but not in a hardened part. Email them for instructions covering how the parts are welded together. Hardened and mild steel parts are welded together similarly as cast iron parts are welded. Temperature is raised to a level based on the metals involved, the parts are welded then cooled slowly. Specific welding rods or filler wire are used. Close finish fit of the driveshaft and pinion gear shaft is essential for reasonable lifespan of the parts.

What happened to the lubrication of the splined sleeve? Did much of it migrate onto the silicone plug?

Dunno about the migration. Iíve only just done the silicone plug, and put it back together.
