I am throwing everything back together after putting that new column in . I was aligning the clutch's, got the center to center right, then i went to do the offset. The offset was way off and even with no shims behind the secondary(secondary is sitting flush with the jackshaft bearing) and the motor slid all the way over i still have about 18-20mm offset. So i started thinking that the steel spacer that is attatched to the back side of the secondary is to long, thus not the letting secondary to sick back far enough. That is the only thing i can see happening. The part # on the secondary is 8BV01, does this seem right??
If i cant get his figured out, i am going to bring the secondary to the machine shop and have them machine .150" or so off the spacer, then i can just shim it up to get the offset right. Does anyone know if that is the right secondary??

Or could the primary possibly get sucked in to far??

Well if it was aligned correctly before you started then you must not have something installed right. Are you messuring the offset on the back or the secondary sheave. I like to use a staight edge and put it inbetween the secondary sheaves and align it with the center of the primary with the outer edge of the staight edge.
 
I dont see how it could have been aligned properly before i started. The only thing that could mess up the offset is the secondary being wrong or the primary clutch getting sucked up to far on the crank. The motor is sitting where it should and the clutches were torqued to spec.
Does anybody have a measurement on the space from the back side of the primary to the frame plate?

are you POSITIVE that you are measuring this in the right place? It is not easy to be off that far, and especially if you are saying you have no more adjustablility.
 
I am measuring the backside of the secondary to the backside of the primary. I am using a 15mm offset tool and even with the motor slid all the way over, i still have 2-3mm to much offset. :o|

If someone can measure for me on a srx the distance between the back side of the primary to the the frame, i could compare to see if the primary is sucked on the crank to far...??

clutch off set

There must be something not together correctly somewhere. Hard to tell without seeing it.
I would recomend that you do not cut the center part of you secondary. At full shift out, the sheeve is very close to the frame. I have a Team roller secondary for my SRX and it rubs on the frame as is when completely opened up. Machining the part is only masking the real issue.
Just trying to save you from creating another problem.

Good luck.
 
Everything is put back together correctly, The motor is sitting true on the motor mounts, so i know the motor is where it needs to be. The clutches could be the only problem. Do some yamaha primary's have a different taper inside the primary to let it suck on the crank farther than others?? Maybe someone put a different primary on the sled or a different secondary. If someone could measure the the back of clutch to the frame distances that would be helpful. thanks for the concern about the scondary hitting, that makes sense and wouldnt want that to happen! #$%&*

clutch measurement

Finally home for the day and measured mine. It's slightly over 3/4" from the flat part of the frame to the back of the primary. The back edge of the clutch if flush with the edge of the bent out portion of the frame. This is on a 2001 SRX.

Hope this helps.

Good luck.
 
I appreciate you taking some time to check it, thanks alot. I will check it tomorrow. If that checks out then it has to be my secondary. I will let you know.

Off the top of my head, that seems about where where mine is as well(flush with the bend)

It could be the alignment tool you are using. I have heard of some of them not being right. I would try the center to center alignment that I mentioned.
 
I got the center to center right on, I am using a Kent Moore 15mm offset tool that i borrowed from my local yami dealer.

Also, i checked the distance from the primary to the frame and it is flush with the edge of the bend. So it HAS to be in my sencondary.
 
I am not talking about center to center distance. Check your offset by the center of the secondary and the primary as I discribed in a previous post.
