Lightbulb Stator change grow into a project!

What started out as realizing I was going to have to replace my stator is growing into a project but I am getting excited about the potential.

My VK750 has had some kind of weird slippage in the drive, ever since I've owned it. When you start it up cold and let out the clutch, quick, it makes kind of a "ZZZZIP" sound then catches suddenly. I've learned to be gentle with the clutch but it still occurs once in a while when it's first fired up. Once it's warmed up it does not seem to happen much. It caught my mechanic off guard the first time he tried the bike and he is not sure what would cause it. Best guess is perhaps a worn clutch plate or two.

So I am thinking now, if I am going to do this Stator and Damper change-out, then I may as well do the clutch too. But rather than use the Hobby Shop on base, I've talked to a few guys at work and they are checking with some people they know who have garages and also live here on Big Coppitt Key. If I can find someone near me who is willing to rent me their garage for thirty days, I'll just pull the engine out, put it on a bench and do it all. Stator, dampers, clutch, ACCT to MCCT, Pick-up Coils and the wiring for the new Mosfet unit. I may even want to do a re-paint on the engine. It would also be a good time to check my splines. We have Moly at work that they use on the jets, (F-5 Tiger II) and I could just scoop some into a zip lock baggie. Jet fighter moly on my driveshaft... I like that.

While the engine is out I can do some detail work on the frame, flush and check out the cooling system, maybe a little touch up painting. The chrome has corroded and rusted off of many of the original nuts and bolts so maybe replace as many as possible with marine grade stainless steel.

I don't want to start until I have everything. I've got a few things now but need to get a few tools and order the clutch and stator. Is there a specific stator that any of you can recommend?
Also, my mechanic tells me he has a complete, original VK750 exhaust system in his back room so I'll be checking that out and see what shape it's in.

I basically did the same thing to mine while I had it out for the dampers. Repainted it, did the R/R, cleaned the stator. Meant to do the pickup coils, but that's for another day...

It's nice to work on it while you have it all out!

Let me know how new clutch plates work for you. That ZIIIRT sound you talk about is called "coffee grinder syndrome" from what I gather, and can be helped by drilling the clutch basket (not a mod I really wanna do) but if clutch plates help I could do a job like that.

that is most likely what we call "Coffee Grinder Syndrome". happens most often on cold engines/clutches. not really harmful, but can be un-nerving if not ready for it.

good news is, Ma-Kaw released a TSB about it, the 'cure' is to drill holes in the clutch basket in a spiral pattern. it seems its an oiling issue (either too much or not enough, I dont know which) when the oil is cold and thicker.

Also, some oils seem to do it more than others. YMMV here.

and by all means, check/grease them splines!

Yeah, it's a big help around here. My bike wouldn't be half of what it is without this site.

I will say that working the clutch about 20 times while in neutral while the bike warms up helps with coffee grinder syndrome, as does slipping the clutch while at a standstill for the first few stop signs/lights (what I mean is letting the clutch grab a little bit while idling at a stop, which I suppose helps to work oil inbetween the plates and warm them up a bit, reducing the grinding noise when I go to take off)

Still waiting for some stator recommendations. A brief look online brings up quite a few in different price ranges so I assume some must be better than others.

OEM or rewind are the only acceptable options imo.

Ricks, Electrosport, NoNameChinaBrand, etc are all the same crap. Worthless under-insulated crap.

Agreed, with what tanner posted, include Caltric in the same group.

You might contact these folks and see if they are still selling rewinds. This listing ended May 5, and they sold five. Willescycle is also affiliated some way with Cycletronics. Was given this link last year and they were advertising rewinds then.
