You know how when you hit the brakes and let off, you can hear a whine as the sled slows? What causes that noise? My problem is that I hear this noise slightly even when cruising. I'm concerned that something may be out of adjustment.
Since I had the engine out, I'm concerned my clutches may be out of alignment even though I used the alignment tool when I reinstalled the engine.

Could it be that I have my chain misadjusted? I went finger tight and backed it off 1/4 turn.
Looking for some places to start here.

Thanks
 

Thanks Yami. Can you elaborate a little. I can see the spring is in hole 6 on the outside of the secondary. The spring is black with a white? paint dot. Original owner said all clutching is stock. How do I check to see what the inner hole is? I'm kind of new to clutches. I can pull the secondary off, but once it comes to disassembling, I'm lost.

Thanks
 
OK, I think my chain was too tight. without the belt on, it took a fair amount of effort to turn the track (while up on a stand). I was finger tight on the tensioner. I went finger snug now and backed off a quarter of a turn.
Now it is easy to turn the track without the belt on. When I run it on a stand, the track takes much longer to slow down to a stop and just kind of creeps at an idle. I think I remember reading this was the desirable adjustment.

I think they may have been hurting my gas mileage as well. Yesterday isn't a good measure because I only got 5 mpg but I was braking trail. In January I got between 8 and 10, which I think was low for a stock viper on nice groomed trails. I'm leaving tonight and heading toward Hayward, Wi, so hopefully I can get this thing dialed in so next year I'm ready to put on thousands of miles - a guy can dream I guess.
