Yeah it sounds like it is actually shifting too much. Do you have a tach, and if so what does it say? Basically my guess is your secondary spring is too loose so it shifts out too much at higher speeds, thus not giving you enough power to accelerate to your previous top speed. And since it is too loose it can't close the secondary fully when you stop, and that explains why the belt is riding too low. Is the belt hanging loose on the primary or is it tight? If it's tight but down 4mm in the secondary it's got to be the wrong belt. If it's loose in the primary then your secondary spring is too loose or shimmed open too much.it runs good snaps out of the hole and gets to about 70-75 then doesnt shift like your stuck in a gear. where b4 the problem , it wasnt that quick out of the whole, but it would definatly start shiffting around that speed and i could hit 85 to 90. i have the original belt and tried it same thing. the top of the belt is at least 4mm down.
thanks for the info, im gonna do that and try a new spring. the first time i took the secondary apart (a couple years ago)i didnt know what i was doing. so could be something i did.[/b]
I've done both no preload and reversed preload several times myself :whistling: so yeah, double check. hehehe good times. That older Yamaha secondary is hard to work on, basically it's the same as Polaris. 96 and newer are much easier to figure out and actually do the work, they are designed more like a Cat secondary.Ah yes I remember now! haha. You have to twist the secondary REALLY hard. Make sure the spring is right direction![/b]
weird, I live in sodus, about 5 miles from Stones! They really are great guys there, but I have to take the exhaust seal back, its way too small for my sled (but right part number?) I think that is something to do with the GYT exhaust...so i finally figured that 1 out last year and got to ride it at least ,thanks to stones sled in newark. great guys there.[/b]
