In your belt deflection adjustment procedure you should indicate that people need to mark their sheaves so they go back together the same way. If not some of you may end up with an unbalanced secondary pulley.

 

Prairie,

Not sure what is on Nyrocs site but the rear sheave will only go on one way as there is a spline that works on the shaft and it is impossible to mix up the inner and outer sheaves. Could be Nyroc was referring to marking the sheave so you can line up on the spot where it mates to the spline on the shaft. Just my thoughts.

 

I believe he was refering to when you split the sheaves to remove or install the shims to set the belt deflection that you should mark both halves to make sure you line the 2 halves back up as they were to help keep them in balance. When I talked with Mike Penland about the belt deflection he told me to make sure I did this also.

 

Prairiewrench,

True the sheaves can be only 180 degrees out of sinc so it is realy that not that big of deal. Although I have trued and balanced mine on the lathe this is something you might think about when it is time to race.

 

I didn't do anything like that but I haven't had any problems with mine. Do you think I may have problems in the future?

 

Montess,

I haven't had any problems reversing mine I have reversed the sheave just to see if there is any vibration and it doesn't seem to bother. The sheave still has to grip the belt and the belt I would think will take out any imperfections thats my thoughts. If those little ***** that slide in the hollow shaft bind, that would be the only limiting factor I would think.

 

Yep, It makes sense to put the halves back to their original position, relative to each other. As I recall, you would have a 1 in 4 chance of reinstalling the halves back to their original position if you don't mark 'em.

 

I looked and never saw any balancing marks so i figured that they where cast and machined and it wouldn't make any difference. If they had to go back a certain way you would have thought that they would have been specifically keyed for it.

 

Gee, I feel bad for nyroc... I think we sometimes expect him to be the one-stop information center....

My thanks to him for taking the time to provide such a service... I bet if Kawi was to put together a website such as his it would have cost them $15 to 25, 000. and thats a conservative estimate. Plus they would charge us to access such information.

 

I'm am pretty sharp in some ways, but I am not the source of all 650 wisdom. I learned what I put on the website on these forums. I am concerned about being bias, or downright inaccurate.

It may look like I know a lot to newbies, which is true, but lots of people have done much deeper research into many 650 related subjects than I have, and therefore have better knowlege about at least one aspect of the 650.

I don't feel like getting too technical on the website. It is just too much writing to do. Plus, if I don't really understand something that well, I could butcher the subject, or get it wrong entirely.

I would like to get kawasaki to send me some quads to persuade me to keep it up, and possibly cover other models better. But I stink at web design, and I don't have a very visually pleasing website yet.
