norsseman Sky,
I showed them Fergy's excellent write up on Lubing the Splines, but didn't show them Diana's Clutch basket mod.
The stealership's response to seeing Fergy's pic's was. . . Ya we have contacted KAW before on not enough grease on splines of several different
bikes to no avail.

Just found Diana's Coffee Grinder Mod fix photo, will incluce it with my letter to KAW Motors USA, I'm sure it will help my case.

I couldn't have said it better . . . Personally, I wouldn't trust a Kaw mech to work on a skate board let alone my bike!!

Sky Rider Norseman,
Have you tried showing the dealer the picture that Diana posted with the clutch basket mod? It's from Kaw so they can't argue too much about the fix for the coffee grinder sound.

Sky Rider If you follow the tutorial, it will take you about 2 hours and you will save at least $150. The 2 hours is assuming you know absolutly nothing about mechanical things. It will be less if you are more familiar with using tools and the like. Personally, I wouldn't trust a Kaw mech to work on a skate board let alone my bike!! I haven't been too impressed with our dealer out here and I've read too many posts here that don't do anything to change that opinion.

DeForestSD BTW, Fergy kudos on your tutorials. Excellent!

DeForestSD Thanks, Fergy for the sage advice. It's better to be safe than sorry. I'm in Rancho Penasquitos near San Diego. There's a Kawa dealer in nearby but I'm sure they'll be quite expensive. I'll see what they quote. Thanks again.

fergy Actually, it's the lack of lube that starts grinding metal to metal, heating up and chewing up the teeth of both the splines on the final drive and the coupling on the drive shaft. If there's not an adequate amount of moly on them, it will start to wear out. So, if it's dry or the wrong lube was used and has vaporized or hardened, dried out etc., every time you ride you will be doing a bit more damage.

fergy Unfortunately there's no symptom of coming failure, just the sound like loose lug nuts inside a hubcap when suddenly your bike just loses all forward push, but the engine still revs while in gear, when it actually fails. It won't slip until it can slip and once it can slip, it does nothing but slip. Maybe someone in your area is a member here and can help you check it out. I'd sure do it if you were near me.

Thanks for the info. I have an '86 with a little over 21K. I've put about 300 mi. on since buying. I've not been able to get much history from the previous owner but, after running some Seafoam through it, it performs as close to perfect as one could ask for. What a great bike! I sure want to do the right things to keep it that way. However, I do put some stock in the old adage, "If it ain't broke, don't fix it". I guess what I'm wondering is: Are there any known symptoms that would possibly give a timely enough alert that "it's time to lube the splines" or is any symptom too late? If I was more of a wrench (with the proper tools), I'd do it immediately but I'm sure I'll be having to pay someone to do it and it probably won't be cheap. If I was a rich guy, I'd do it every oil change but.....

My dealer acknowledge that many Kawasaki's don't have enough grease on their splines, also acknowledged that he heard the coffee grinder sound (clutch slipping) but said it was minimal, said the smoke was from condensation burning off..(riders behind me can see the blue smoke)

The clutch slipping is a safety concern and Kawasaki should immediately take care of the problem, I read on the net that KAW has an upgrade to the clutch that solves the problem, dealer says he has never heard about it.
Just wondering if anyone has any info on what years were affected by the spline lube issue or is it pretty much across the board?
