The CDI's are different, 700 is 8CH and the 600 8DG. Not sure what the differences are.

I don't know , but wouldn't the curve have to be different?

Check the yamaha parts finder on this website (tried to copy and past the address but it didn't work)
It shows 8ch as discontinued and 8dg for both the 600 and 700s.
That said I don't even know if it really is my problem. Just another idea in hopes of troubleshooting the issue.

I've been working nightshift last few days 5pm-5am. The weather has been warm and beautiful. So after 4hrs of sleep the sunshine forced me out of bed and back to work my sled.
Today I checked my stator with my cheap 30$ multimeter. Every circuit / measurement matched the yamaha specs I found on this site. So that's awsome. I figured it wasn't the problem but still ruling it out still feels good!
Checked everywhere I could on the harness for damage, every connecter etc.... Found nothing. Rechecked compression just because it's fun. Got 116 psi across all three.
Went out for a ride. Ran poorly at first. Checked plugs. They looked ok. Or atleast like nothing was being destroyed. Kept going, Started running good . Played around for a1/2 hr You could feel a bit of missfire once in a while. But still it was running nice. Checked plugs ok. On my way home it started running poorly again. Still had a great ride in the warm sunny spring time weather. Nice to be reminded my 700 still Ripps!
I still have not ruled out cdi box.

Always ride away from home LOL
Keep looking, you will find it. For the expensive stuff, swap with known good parts. Of course the donor might want the part back, but at least you might find the issue.

Lots of snow for riding still.
But I finished work this morning at 5am. Needed sleep and it was ugly, rainy all day. Tomorrow I'm off, and it's supposed to be sunny. I decided to be patient. I'am really curious if it works !

From bad to worse
Went out for ride. Sled was running terrible again. Drove out about 5km before I got fed up and switched CDI box. Started right up no issue but again as soon as I aproched 6000rpm started acting up badly. So running a 600 triple cdi does work fine. But it's not the solution to my hesitation problem.
The weather was nice, so I just kept cruising at 30mph. Keeping the revs under 6k and on stretches I'd open her up. T'ill about 14kms out my ski just caught the edge on the very narrow trail and pulled the sled in.
So I was stuck! No problem! I thought. I've been stuck like this 20 times before, I always get out!
Dug it out, gave it gas, smoked my belt. Raised the hood, moved the belt a bit, closed hood, and tried again. Sled moved forward about 4ft but then burnt the belt again. Atleast I was out of the hole I was stuck in. Changed belts, cleaned around the sled again and I was sure this time I was getting back on the trail! Here we go! Just as I apply throttle and gave it a shot of gas, my steering broke off! WTF! Broke off just below the weld!
It took two more attempts and burnt my spare belt but I managed to get my sled back on the trail with no steering!
From that point on I started walking home. Trail was very soft and slushy. I still had phone reception so I tried calling my buddy every 10min. After 1.5 hours of walking, still 7km from home I eventually did get a hold of him and he came and picked me up 1/2 hr after.
I was very wet and tired at this point. But went back to my sled, turned it around, tied slings (thank God I had them) from my skies to his rear hitch, and he towed me for 12km. My buddy was worried about overheating his sled and having traction problems in all the slush. So I actually drove my sled under its own power the entire time, while he basically steered me all the way home.
Me and my snowmobile are home safe. I'm soar, tired and fed up. Goodnight.

Better day then yesterday.
Drove out to the city to pick up a new belt from the yamaha dealer. While I was there I tried talking to one on the techs of my hesitation problem. He said "You've cover all the bases well. The only thing left would be to check and adjust your power valves". I said " I don't have power valves". He said " Then I don't know unless you bring it in".
I walked out without any answers.
Once back home I ripped the steering bolts off, cleaned and rewelded the steering shaft inside and out with my MIG. Went very well actually and the steering feels streight and true. So that's done and all reassembled!
After that I cleaned my clutches with a Scotchbright pad, paper towel and non chlorinated parts cleaner. Burning two belts Yesterday left alot of rubber on them. After cleaning installed, the new belt.
So I'm right back where I started from with a really nice sled that is still a bit sick.

Have you checked your exhaust for blockages, leak's etc....
What about reeds i don't recall if that was covered already or not.

I though of something last night. Look on the secondary about 3/4s the way up. This would be the place where the belt would ride while you are at that problem rpm. Look and see if there is and deviation from the flat face it should be.
Are your exhaust springs good-n-STRONG. Fron manifold to pipe, and pipe to muffler? I've gotten replacements at ACE or Menards in the isle with all of those pull-out trays.
I'm just spit-ballin here. I'm out of ideas.

I am still saying the clutch is a good possibility. Try swapping both clutches with your brother. It won't run the correct rpm but you would be able to tell if it is better in that rpm range. Quick and easy check. You would be surprised on what a clutch problem can seem like. Just a thought and it would be easy to swap and rule out.

I too have had a clutch problem mask itself as a fuel issue.

I've gone over the wiring harness many times, never found anything. (yet anyways)
Exhaust spring are good and strong. They hold everything tight. The secondary sheave surfaces are in great condition no weird wear patters.
My brother's clutchs are not good candidates for troubleshooting. They are very high mileage and the primary was starting to seized up when he parked it three years ago. But I have plenty of time to remove my primary, take of the cover and inspect it before tonight's nightshift. It's worth a try anyways.
I'll keep you posted.

Have you removed the secondary? Making sure there is no gunky build up of cr@p on the shaft.

Did you put new springs in the clutches? Could be as simple as that. Definitely doesn't hurt to inspect them but more than likely you will not be able to see what is wrong. Could be just time for a clutch rebuild. Too bad your brothers clutches wont work because that would be the best way to find out if it is the clutches. Keep at it and you will get it figured out.
