2000 MM700 what to look for.

2000 MM 700 3800mi, Elkholm tunnel rolled chain case159" 2" or 2 1/4"? With anti ratchet drivers, SLP ski, lightweight trailing arms, and lightweight radius and control arms, also bender triple pipes, needs 3 primary clutch rollers replaced?

He wants 2,000 for it I'm going to do a compression test what is the worst low # i should go? What do i look for in tunnel damage? Anything to be sketchy about with these sleds?

Last sled i owned was a 94 vmax 600 not a comfy workhorse.

Please help with any suggestions possibly picking it up tonight.

make sure backing plates were installed where the front pivot arm attaches to the tunnel or look for signs of cracking.

depending on what trailing arms are on there, look for cracking of the welds where the rad rods bolt on.

pay close attention to the primary clutch sheaves and look for any cracking. if the rollers need replaced, chances are the weight bushings may need attention and could be a result of the movable sheave bushing requiring attention. not a deal breaker, just be aware.

compression tests can vary, but rule of thumb is 125psi. dont be alarmed if its less, unless its way less and all three should be within about 10% of each other.

figure a couple hundred at the worst for the clutch and use it as a bargaining chip. dont forget to remind the seller that recouping dollars spent on add ons usually doesnt happen, although what has been done makes that sled work incredible over stock. price is fair, but no exceptional deal in my opinion.

where you at in wa?

That's alot of great info, I've been out of sledding along time, I'm just hoping its a good sled to start with again, kinda like Yamaha's while some frown upon them, I'm located in Monroe, Wa. I hope none of the welds are cracked? And i can find no info on elkholm, would this be a setup elkholm did? Exh, ski, arms etc? Would the suspension be aftermarket or stock? And would they of done reeds?;

ekholm hasnt made those tunnels for years. mtn performance had the dealership on them for awhile but long since unavailable. ekholm had the right idea, mpi ruined it. it was the best thing to do to the mtn maxes back in the day. original installs forgot the backing plates on where the front arms mount in the tunnel do to confusion with the instructions.

the skid is more than likely a stocker, but who knows. any of the other add ons would be up to the original owner. if your lucky, theres a set of northern lites or fabcraft arms on there. no need to look twice at these, but if you see mtn perf on there, inspect closely!

the rest of the upgrades, properly tuned, make that a killer sled. look for signs of reed spacers(obvious aluminum spacers at the cages) and hope aftermarkets were added.

if the slp's are powder pros, thats a plus. you may even look into the airbox to see if any mods have been done to it.

your on the opposite side of the state i believe i have been through monroe. i am over here on the wa/id border.

trailing arms appear to be gen 1's from mpi. the better ones back when they made some good stuff.

skis must be an early version of the slp's. dont quite recall them in that format.

looks like different bars, almost mtn viperish. thats a bonus! along with the added crossbar and ridgid strap!

i would almost question the track length based on the pictures or possibly the skid being from a 2000 model. seems to be alot of space left over at the end of the tunnel. those tunnels were offered in 136, 144, 151, 156, and 159 configurations. same front portion of the tunnel, different tunnel extension lengths. be sure there is a rear heat exhanger back there and not just a crossover tube.

looks like a good deal. those tunnels are powdercoated in case you dont care for the yellow. takes a bit to strip them but not much to recoat with rattle can.

So what your saying is that it does not appear to be a 159? Im assuming thats a stock 141 in the background? How do you measure the track length so i can figure out what it is? I can't pick it up till Sunday.

sled in the background would have been a 136 in stock trim.

pictures can be deceiving, but to confirm track length, count the open windows and multiply by 2.52. mark one window with tape or whatever and rotate the track while counting windows until you get back to the mark. being it has anti-ratchet drivers, all the windows must be open and its an easy count.

you should count about 63 windows for a 159.

almost looks like the transfer rods are gone. hopefully replaced with a transfer enhancement kit.

yamaha used a control rod to adjust the coupling of the suspension. no disrespect intended, but there is probably a few days reading on the subject if you did a search on coupled vs uncoupled suspensions.

somewhere along the lines someone figured out that you could remove the transfer rods on the yamahas and almost control the point of coupling in the suspensions cycle by using straps similar to whats on the front of the skid. the end result was alot more weight transfer to the track. read that as the track grabs and the front of the sled lifts. this is a good thing to a point. i have bypassed the transfer rods for years. if that sled has the adjustable straps vs the oem rods, you will be a happy guy once you find the sweet spot.
