I didn't get a chance to ride this past weekend. I'm using the 9 plug. About 60 degrees at 800 ft. I checked the slide when I installed the carb to make sure the slide is going all the way up. I don't know of any bolt in the throttle housing. It might have been removed years ago. My valves were clearanced with the install of A2 cams just before all of this. I do think I need a 98 needle. I'm anxious to try it. I only use Mikuni tuning parts. Thanks for the insight, I will make certain to keep you updated what I end up with.

 

I just got the 98 needle sent out today, sorry it took sooooo long to find it.

 

Not a problem. Thank you for helping out.

 

I finally got a chance to try the 98 needle (thank you Stir). The bottom end is a bit more responsive. The response could be tuned with the pump though. I'll know more when I trail ride. Last time, it seemed to load up. Now it shouldn't. Now, when I decelerate it pops out of the exhaust a bit. Not real bad though. I could live with it if it don't mean anything bad. Maybe now I need to go up to a 30 pilot. I have a 25 in now and that might have been needed to help compensate for the rich needle. Thats all I have for now. On the track it is fun. I'll know more after my next trail ride. Thanks guys.
