i just bought a mm700 for 500 bucks because it needed a new topend. i'm wondering what you guys think the jetting should be. i'm trying to be cautious cause i dont want to rebuild it then it blow up again. it has triple pipes 20cc domes with peak performance head, and vforce reeds. i dont know the clutch spring weights. but if you guys can help me out with anything i'd appreciate it. i will also be riding at about 6000 feet. here is a picture of the pipes if anyone knows what kind they are.

should be able to safely do over 8,200 with pipes. 8,200 is good for stock, but with pipes he should be closer to 8,700-8,900.
 
Power inc centre dumps run a max of 8200...no higher. 8-8100 even better. I tuned & ran many sets of em at lower elevation. Anything over 8200 they lay down badly.
There is jetting & clutching specs in the tech pages for these pipes under engine section.
The install specs specifically state do not under any circumstances run over 8200 rpm with these pipes or performance falls off badly!!!

hey thank you guys, i had this same post on snowmobileforum.com for 2 weeks and got nothing.. seems like you nailed it on the head in under a day. any opinions of these pipes?
 
well i'm not really worried about top end, are the end dumps just better for top end or are they really just better all around
 
um i've been looking for the tech page on jetting and clutching for this set up for about 2 hours now, either i'm dumb or they arent there, either way i need help finding it... any help please ?
