XS650 Junkie
I've been able to use the search funtion to answer most of my questions but so far I haven't been able to find the answer to this one.
Let me back up a bit. The bike is an XS650B (1975) and did sit unused for a long time. When I got the bike (still a non runner) the airboxs had been taken off. In the deal, I got a couple of (still in the box) Yamaha air filters. I didn't pay much attention to them because I had other stuff to do to try to get the bike running and figured I'd get to them in time.
Well the time came this morning. I cleaned up the boxes and gave them a new coat of paint and all new rubber bits. When I went to install the new filters something didn't look right. ( I had printed the page out of the parts book and had that with me) As it turns out the filters are for a later model (533-14451-00-00) so I was thinking I need to order the correct ones. BUT, there have been a couple of bits on this bike that didn't add up to 1975. Like it has a 1976 type side stand and early type (two hole back) petcocks.
So what I'm wondering is...........................
Is there a phycial difference between the 1975 air box and lets say a 1977??? If there is, what is the difference?
Also, my boxes did not have the springs (element set) with them (447-14468-01-00) what do these look like and where do they go?
I did find something the 5twins wrote:
"There's no need for the filter to be open on the back and fit up snug to the cross over. The cross over will do its job just the same (equalize pressure between the two boxes) whether the filters press against it or not. Yamaha probably realized this after a couple years and re-designed the element. No doubt the new style was easier and cheaper to make too. You could probably just run those later filters in your '75 boxes."
Just trying to figure out this last littlle bit before I give it a kick.
