I bought this sled at the beginning of the season and had a lot of work done to it.  I had the carbs totally gone through, synced, new trottle cable, re-jetted, new clutch.  I took it up and it ran great for a half day.  Now it cuts out at about 6500 to 8500 rpm.

Thinking maybee the coil or fuel pump.

Any ideas?

Your going to have to give us a little more info. than cutting out between 6500 and 8500.  Are you riding in the Mountains, What do you mean by a new Clutch, Clutch Kit?  Please give us some more info. so we can help!

yea I ride in the mountains at 9000' to 11000'.  I replaced the primary clutch and it is set up to engage at about 4000rpm.  It runs great at idle and the low end but when I hammer it bogs and cuts out.  I cant decide if it is electrical or a fuel system problem.  I check my plugs periodically and they are perfect.  Any ideas would be greatly appreciated.

What size Main Jets are you running???  Did you just Replace the Spring in the Primary Clutch?

I will get some more information on what they put into it.  But the guy that worked on it is very meticulous and am sure the carbs are set up right.  I test drove the sled fresh out of the shop and it was running awesome.  They replaced the whole primary cluth with the 9 stage clutch and it has a orange spring in it but I am not sure about the weights.  It has very good low end and that is all I am concerned with.  

I also wondered about the altitude compensating system and have heard about the switches on the carbs that some people are jumpering together what is this all about?  I don't understand what they are supposed to do?

As you can probably tell I am no mechanic but I am eager to learn as I have learned a lot since finding this website and reading all forums.  Really appreciate the feedback.
