What exhaust is this

Just picked up two Polaris 1999 rmk 700's one has a twin pipe exhaust and the hook spots that are on the manifold for the spring are either missing or I have the wrong spring. What exhaust is this? Factory? How do I fix?

Polaris xc 600 smokes a lot!

I just bought a 2001 Polaris indy xc 600 that the seller told me he just rebuilt the top end and carbs. The machine gives off a ton of smoke right now. I just found out it was built in August of 99 so it has to be a 2000.How worried should I be about the smoke? Any comments appreciated.

**Help** 2004 Arctic Cat F7 CARB

Last year I bought 2004 Arctic Cat F7 CARB Model. The sled seemed to run just fine. Just before winter I pulled the carbs off the sled to clean them before the snow flew. After cleaning the carbs the sled also seemed to run fine. Would fire up 1-3 pulls every time. One night we went on a ride for a few hours and the sled acted just fine. The next morning I went to start the sled and it would not fire. After pulling on the sled 20-30 times I got the sled to fire but only seemed to be running on 1 cylinder and my gauges were jus barely lighting up. After about 1-2 minutes of running like shit (and I could not throttle it out) the 2nd cylinder came into play and the sled began to run as expected. All day if I shut the sled down and fired back up when fairly warm it ran fine. If I let it get cold cold it would go back to the same problem, running like shit on one cylinder for a few minutes until the other one fired up. I did a compression test and it was 125 across the board. I changed out the plugs and the problem stayed the same. Sled has new fuel in it and I ran a few tanks though it cause as stated runs fine once warm. I did notice randomly a boggin issue mid throttle. I rode the sled about 4-5 times after being in Michigan we don't get a chance to ride often. I did notice if I sprayed it with starting fluid it would try to fire much easier but still only on 1 cylinder until it runs for a few minutes.

Looking to see if anyone has any advice where to start. I am thinking its a fueling issue or ignition but don't want to just toss parts at it.

Any help would be appreciated.

Stud Length

Both sleds have the standard issue .78" stock track. I may have the option of picking up an old track to use as a track mat on my bridge that crosses a stream on our property. If that track is studded, would a longer stud than a .875" cause issues? I have to image the longer the stud, the more pressure it puts on the track?

Excel III 340 spark issue

Hey everyone just pulling the old 340 out for winter and was seeing if she'd fire up. Fired up second pull sounded great and then boom just started hitting on one cylinder. So it's the right side that's hitting only ever so often and it'll just be one hit and done , unless I just set the plug cap on the plug it arcs and runs like it should any suggestions ?
