Was wondering what zirk fitting there are in the engine compartment? Is there any on the primary or secondary shaft??? I thought I had seen one near the speedo cable before but I may be wrong. (maybe a different sled).
forgot to mention its a 2002 viper
Check your steering pivot. Nothing by the clutches, some people have installed zerks at the speedo pickup below the secondary clutch on the sleds with mechanical speedos, but your viper has the electronic pickup so it doesn't have a housing to hold the grease. Other manufacturer's sleds do have a grease fitting there, too bad Yamaha never felt the need to incorporate one, that bearing can be a problem.
What you can do is pick the seal out of the bearing, exposing your balls and cage, or at least one side of them. Clean out the old crap as much as you can and pack new grease in there. I wouldn't pack it completely full, new bearings never are, and it would just add friction and may try to push the seal back off and may leak out. Instead try to push the grease thru to the other side in a few spots around the bearing. If the bearing is rusty inside, it's a crapshoot how much longer it'll last.
Do this for both the driveshaft bearing behind the speedo pickup, and the jackshaft bearing behind the secondary clutch. Can also do this with your rear suspension wheel bearings. In all cases, just be careful and try not to damage the seal, and keep an eye on it during the season and recheck every year to keep good grease in there.
