kanuck69 That would be a pretty cheep fix for an essensialy new shaft!

Ccspinner It was a friend's he got the part, I will see if I can find it.
I know it was out of a Kawasaki ATV that was Shaft drive, they listed a part for it, He had a 1500 but looked the same size as ours.
I still have the bad U Joint on my Tool box at work.
I will have to check it with a 750 shaft and see if it is the same size.
HE said it was $20

kanuck69 You replaced the u-joint. That part info would be quite valuable. My shaft was neer perfect, if I could get a universal for the other shaft it would be an excellent replacement for someone. But I felt finding a Random Universal would be too difficult . Seeing how most shops only want your money not your time anymore.

Ccspinner That is the 3rd U joint I have heard of going bad on a Vulcan.
I have seen 2 myself and replaced 1 of them.
That is strange.

kanuck69 To put an end to this thread, now that I've replaced the drive shaft that had a bad universal... I'm concluding that the "Whoa" sound was the universal. When it went it vibrated to much due to it partialy sticking causing it to hit the side of the swing arm/shaft housing. With the new shaft "Every Thing" sounds as it should! (except for the acct, which I'm working on =)

kanuck69 Just to add closure, The spline closest to the engine was bone dry but in very good shape. The rear spine was greased. I'm guessing who ever did the last tire change lubed the rear but didn't bother with the front. White lithiumed the universal, the final drive gear, changed the oil there and still I have the Whoa, Whoa, Whoa, Whoa, Whoa, sound I'm thinking it might have always been there but as soon as you notice something, that's all you can hear. On a good note I don't think it is quite as noticable. So something good came out of it.

fergy Spline lube procedure below.

You can't inspect your bike too much! Tires are way too often overlooked and can cause DEATH! Pretty important to know what kind of shape your tires are in! Just give your bike a nice once over every time you are getting ready to get on her. Look for loose nuts and bolts, anything that seems out of place.

I was getting ready to head out on a weekend road trip and while giving my bike the once over, noticed my rear upper engine mount (11 inch bolt!) had come out and was gone. I had felt something hit my right leg the night before coming home from work, and figured it had been a large bug or rock kicked up from the road. Never in my wildest dreams would I have thought it was the 11 inch bolt that makes the upper rear engine mount! My bike is a 2002, and I wouldn't have imagined something like that could have rattled loose without me knowing about it.

kanuck69 Thanks I'll get right on it!

theauhawk You'll want to lube your splines with a grease that has at least 60% molybdenum disulfide (us bikers call this stuff "moly"). Just regular general purpose grease simply will not do.

This fancy-sounding chemical allows grease to perform well at extreme pressures and temps--for a long time.

Incidentally, all shaft drive bikes require this periodic lubrication treatment--and not just your 750.

You can read about what greases to get for your splines, and why, by visiting the following link:

http://motorcycleinfo.calsci.com/Shaft.html#Splines

...and then scroll down the page to "spline lubricants".

Incidentally, the above link will show you a page with still other links, all of which make for very good reading on bike care and maintenance.

Fergy has a wonderful writeup in his signature on how to lube the splines yourself. If you've acquired your bike recently, it's really a good idea to inspect the splines for proper grease amounts--the alternative is very $$$$$$$$$$$$$$$!!!

Also: it's not a bad idea to check your tire pressure before each ride. Especially before the first ride of the day.

kanuck69 Thanks, I didn't think the tire pressure should be checked weekly. But I will from now on, Thanks. I don't think the sound is that of any exhaust, But I'll check that too. The splines is a good thought. I haven't tor into those at all yet. Do you have a quick refrence for the greese? It would save time of trying to look it up if it was postrd here. I have a bad habbit of finding useful info then forgeting which tread it was in. I figure while I'm checking, Might as well lube right! Thanks.
