I have SXR 700 with Aaen pipes on it, it is my backup sled and I let friends ride it when they come up.

Sometimes you will be running about 45-50 and try to pin it and it will just kind of hang there and not take off like it should. If you let off and hit it again it will go right up past 80 no problem.

Do you guys think maybe I just need to increase my secondary wrap or what? I am at 3-3 now.
 
I am having trouble tuning my aaens mine loads up on low end. running 147.5 mains needles in mid with 2 washer under except pto is down one more with one washer under
 
Maybe like 1/4 to 1/2 throttle. I'm not really sure it's loading up. It runs snappy up and down and actually has a slight idle hang, plugs look good. Just sometimes when trail cruising for awhile you pin it and it just doesn't seem to take off like it should till you get out of it for a second and then hit it. I'll check things out better this weekend. I just wanted to get some ideas first. Thanks.

Whats the secondary set at?
 
Secondary is at 3-3. I was thinking maybe going to 6-1 just to see if that helps.

I'll check the bushings too this weekend.

Thanks guys.
 
Well I pulled the secondary and checked the bushings, cleaned it and put the spring at 6-1. Rode it for awhile and it was ok and then started doing it again, so I decided to change the belt and that cleared everything up. Sled it back to itself again. The belt looked pretty good at first glance but the sides were pretty glazed.

Thanks for the help

At least you found the issue. The belt can do wonders.
 
I'm sure you could de-glaze it, but more important is the width of the belt because that affects how well the clutches can grab them. I usually change belts when they lose a mm and make them a backup, but this is my secondary sled so I kind of slacked off on it. :p
