I just went right to 70. It runs about 500rpm higher than stock at about 40mph on a flat trail. I put it back to stock when trail riding with slow people so it's not screaming all the time.
I haven't had the primary all the way apart on a Yamaha. You may need to take the spider off to get to the buttons, that would require special tools in most cases.
Increasing the tension in the secondary makes it backshift harder. Also makes it harder for the secondary to open, which is like staying in a lower gear longer. As far as it taking a lot of rpm to get moving that's in your primary clutch. It should engage around 4000 rpm.
@@Whitestrash thanks so much. I have a 99 venture 500 and it revs really high when riding. Like 6500 rpm at 45-50 mph. If you give it gas it goes faster but it’s like it’s in a really low gear almost. You think I should close up the gap on the secondary clutch? The belt sits flush does not protrude over the edge.
It's normal on these sleds for the belt to sit flush or slightly below the secondary. You could see where your secondary is set (like in the video) maybe someone messed with it and it's way off??
Any suggestions for clutch engagement @ 6k rpm? I've replaced my primary & it's still an issue. Any thoughts appreciated. It has to be an issue with my secondary right?
Just trying to understand what you mean by backshift harder. How do we set belt tension? New to the sled world and just trying to educate myself. Thanks for any help you can provide. Paul
I'm no expert on the subject, but backshifting is when the secondary clutch closes back up on deceleration. It also keeps it in a "lower gear"for longer the tighter the spring is. Belt tension should be close as long as your clutch center to center measurement is in spec. You have a little fine tuning adjustment from there (on yamaha) by adding or removing shims on the secondary. There are tons of vids on that procedure. Just look for "yamaha snowmobile belt deflection" and you'll find it.
