what would be a reasonable price for a vmax 4 750 or 800 engine with elec carbs clutch pipe. i found a couple on craigslist anywhere from 300 to a grand. i want to build either a snomoquad or put the engine in a new chassis.

i found one the other day but the guy wont answer its a 750 has all electrical and has clutch for 350 bucks comp is in the 130 range in all cyls has spark ect according to the add but the guy never answers his phone. the one time he did answer his phone he said his grand son hit a tree and destroyed the pipes and chassis and he is sick of seeing the motor.
 
350 is a deal for that motor. 800 motor is better but if your gonna run it stock that 750 motor will treat ya just fine. Better if its from 93-94, has more hp. Clutch alone is worth 150-250 depending on shape. I sold an 800 motor last year with carbs for $1300, that was mid-season and prices were at their peak.

im going to look at a complete sled 94 750 has 9k miles 600 bucks guys claims no odd engine noise im going to bring my comp tester and camera thingy to look at the cylinder walls and what not. how far did these motors go?
 
If taken care of at all 9K is just getting broke in good. I just pulled the pipes and reeds on a 9300+ mile 750 last week and it looked like new. Zero signs of piston wear and the cylinders looked perfect. Comped dead even at 130 and still runs as good as it did with 1500 on the clock.

i checked out that sled from what i could tell the motor seemed strong fired up 3rd pull. needs exhaust doughnut on y pipe seems like the oil pump needs adjustment it smoked alot, no odd smell like anti freeze or anything. engaged around 2800rpm when it engaged it had a slight bog but i am lean twardss it might be low on fuel because it was on E after all. other than that it had some rust on the pipes break disc kinda rusty. but he agreed on 500 bucks i just want your guys opinions. lets say this thing blows could i make my 500 bucks back from selling the carbs pipes clutch ect? not much info but he is the sled http://saginaw.craigslist.org/rvs/3371539431.html

thats a '92, lowest hp for the vmax-4's. Stock pipes on it? Main problem with that motor is the crank coming out of phase. Check pipes for unburned fuel. Motor will show good compression even with a spun crank. You can also check spark plugs for what would appear to be an excessively rich situation. Be particularly wary if one side of the motor seems much richer than the other, this could be hard to spot as the 92's at stock jetting were very rich anyways. 500 bucks and you shouldn't lose money. Those motors can go for a long time as Opsled has stated, I have one showing 33,000 km's which is over 16,000 miles. I have two others showing 24,000 and some change. any other questions just ask.

thats a 92? i do not know much about vmax 4s so if you could help me indicate the year? my main question is though if im getting into some trouble buying this sled. it definitly shows some weather damage i highly doubt it was stored/fogged properly i mean i never fog my sleds but i do occasionally fire them up in the summer just to make sure a rat did chew a wire or somthing and to make sure it have some fresh lube. i know you said the cranks come out of phase id imagine that would cause some balance issue and some hellish vibration? if worst comes i can always take the engine apart and sell the cyls and other parts to make my money back i guess so i might not be taking a loss on this deal but i still have my doubts about it. i just dont want to turn down such an offer i always wanted a vmax 4.
 
there's a few ways to tell the years, first off the engine size, 750's are 92,93,94. Color scheme is also an indicator. 92 were grey, pink and black. 93's had some red in them, but were noticeably diffferent from 92. The front TSS also changed in '93, they became top adjustable whereas the 92's needed the skiis removed to make adjustments. 95 was the start year of the 800 motor and last year of mainly black. 96 was red and 97 had pro-action rear skids in them and a hydraulic brake. There are a score of other differences but those should get ya started. 92 had lowest hp, increased in 93,94, increased also with the 800 in '95.

Surpisingly enough, most people do not report bad vibration when cranks are spun, engine just feels sluggish, not much performance at all. Lots of unburned gas in the pipe of the side that is out of phase. If you want the sled to run, I wouldnt buy that one, it would be for parts. You mentioned putting the engine in another project, if that is your intention then really you are just looking for a motor. A cylinder has to worth 100 bucks x4 and if the crank aint spun thats worth 3 or 400 bucks. Windy is worth about 100 bucks with no cracks. carbs are another 100 at least, rear clutch is the weak part of the 750's, but they work ok if maintained properly. They sell for 50-100 bucks. Primary clutch is for vmax-4's only so they are quite hard to find and could be worth a bit. In 95 they changed they primary to one more similar to the ones used now. Still a vmax-4 stand alone though. those are the major parts, and I think your ahead of the game already.

i think i will buy it take it out on the bay a few times and part it in the spring. that way i can have the satisfaction of riding a 4 cyl sled and still make money.

Bad idea. I have bought a few which were partially parted out cheaply and put them back together. A complete Vmax-4 is worth more than a pile of parts even if not running. Most issues are easy to fix.
 
i called my local bone yard they said they would give me 700 for it blown up so i can go wrong buying it for 500.
 
4-s are an extraordinary buy in my opiniion. Mucho bang fer the buck. A ton of potential left on the table out of the crate which is (on average) non typical for Yamaha. Decent looking, running 440 Exciters can bring well over $500. People look at the market all the time and try to compare $. With a 4 I don't think things are the same. They are a 1 of deal.

Even a 92 listed for over 8K new and was sled of the year on more than one front. $500 is cheap for an animal like that.

There will come a time when they are appreciated for what they are. The tripple two stroke groupies push the 4 back but dime fer dime and mod fer mod and cc fer cc the 4 can still hold it's own or own the tripple.

An awsome engine that is unequaled in the sled world.
