Hey guys,
Beginning of this winter I bought my first sled and a bunch of you guys helped me get the carbs cleaned. I did that and it ran good, but it was running a little rich on the outter 2 cylinders. So I pulled the carbs off yesterday and set all the fuel/air screws to exactly 1.5 turns out and put new spark plugs in. It runs a lot better! Power is there when I hit the throttle. But running about 20 -30 mph it starts to run a little rough. Like it feels like the motor has a slight miss or something. But goes away if I speed up.
Also, if I'm riding the sled around and it's warmed up good, then shut the sled off. Wait about 1 minute, it'll take 5-6 pulls to start back up where as everyone else takes 1 pull. And it's done that since I got it.
When it first starts, it sounds like it's barely going and the lights are real dim, then I tap throttle and it runs normal.
My last question is, what should the idle rpm be set to and you adjust it when the sled is cold or warm?
Thanks guys!

Just about every tamaha triple needs the throttle cracked to start first pull when warm. Where your idle is set to has an effect on this, but try giving it just a crack and that should help.

That mid range burble your talking about is the mid range burble. Once you get to a steady cruising speed and the load drops off your running rich. That is controlled by your jet needles. They can be raised and lowered in fine amounts to fine tune the mid range.

Pm me your email and I'll send you the jetting charts. You can see where you are for elevation and then pick a temp for a starting point. I have a thread going right now in the tech section about needles and temp/elevation. I need to adjust my midrange because I'm too rich but inbetween elevations.
 
Thanks. I'll send my email to you backwoods!
Also, my sled feels like it's has 2 powerbands. Normal sleds, you smash it and it goes mine takes off fast, then hits about 30 - 40 mph and kinda feels like it losing power then a power band hits and it takes off then stops gaining speed about 50-60. Then if I stay in it for a while it feels like another power band hits and it takes off again. What the hell is that about!? Really weird..
