Yamaha Phazer II $100 sled project

Picked this up last week from some hippies on the top of a mountain here in Colorado.

My first sled and I like tinkering. He couldn't get it to start and didn't know what was wrong with it. He thought it was a spark plug wire or carb problem.

Pics of sled he sent me.
Stored outside under tarps



I tried to pull start it and the rope just stayed out after I pulled on it




wires hanging out everywhere, filled with pine needles and smelled like super old gas.


I offered $100 'cause I really didn't know if I wanted and he was happy to let it go.

Took it directly to the car wash and power washed it good.



Then played around with it a bit trying to get spark. I fixed the pull start problem with some lube and it started working good. Engine seemed to have good compression.

I pulled it all apart. The engine bay was filled with 4 inches of pine needles, animal hair, and grease... cleaned it up.

Pulled off the fan and the flywheel to get the magneto removed. I ordered another one off eBay, along with a coil. Waiting on them to come in the mail.

In the mean time, I did some cosmetic stuff. Painted the skis, under the seat, the engine bay, front bumper, engine cover, and patched up the seat and stapled it taught. Just got my hands on everything and cleaned it good.

I also cleaned the carbs. They were missing some gaskets and a cap so I ordered that along with new main jets for my altitude. I downloaded a shop manual online which gave specified jets for elevation.... mine was 130 I'm at 5280.



I also used a buffing wheel on the paint, 3M rubbing compound and Maguires polishing compound.


Engine bay is just primer but clean.

Thanks I enjoy the process, hope I can get it going soon.

Did some painting on it today.
I have a plotter so I cut some logos for it too. I just used primer and Dupli Color GM bright red paint. The old paint was a deeper red and looking tired.
In this pick the only piece that has clear coat on it so far is the engine cover.

I don't really know since I haven't had it running yet. the stator and coil are in my mailbox as of yesterday so I'll try to get those put on it. I am still waiting on carb gaskets though. The tach has 2000 miles on it and it feels good when you pull it over is all I can tell you at this point.

I have a couple more panels to paint/clearcoat then I'll get cracking on the mechanical side of things. New to sleds so it'll be a learning process.

Another pic of the paint still have the fenders to finish up which are in the back there primed grey.



I put the new stator on and the fan, pull start, and new clutch belt. Back together and mounted the engine back in the bay.
Looks pretty raw at this point.

Was it at WOT? That could lead to a low reading.

Otherwise, that engine is a bit on the low side. 120+ is what I like to see. Run it for a bit first to let the rings reseat after sitting, but it may need a refresher if the compression doesn't come back up.

Try again with a couple of oz of oil added to the cylinders and see if it come up a lot or a little.
This will tell you if it is the rings not seating or something else.

As stated above, since the engine has sat for a long time it will have the rings stuck in the lands and will not make the best seal.
Soaking with penetrating oil or ATF or Diesel will loosen them up which will also raise the compression.

On a fanner 110 is normal so 105 isn't bad!
I would also take the exhaust off the block and inspect the piston skirts?
The other thing I want to mention is the front suspension and steering.
I would put grease fittings in the upper coupler that turns the pogos.
Then there is the shim kit to tighten up the linkage!

More pics, worked on getting the engine bay in order. Put in the carbs, and the gas lines, and the throttle cable, airbox, oil tank, exhaust, lined it up and torqued motor down, I put the new coil on.

When I pulled it with my spark plug tester it did not spark, so I was like oh man must be cdi issue also. I put the CDI in my oven for like 20 minutes first 10 minutes at 200 degrees then 10 minutes at 300 degrees. I found a video online saying that can sometimes get ride of moisture with the heat. Well it worked with mine thankfully.

I put starter fluid in it and it fired right up first pull. I still need to work on getting the gas tank on, and the rest of oil/gas lines and some other small things but I am getting there.



Engine bay looks a lot better then when I got it

More work on Phazer II today. Connected the fuel and oil lines and added a Polaris seat.
Picked seat up off of Craigslist today for $60. I don't really like the riding position of the stock seat and mine was ripped up also. Thought I'd give it a try. I think it was off a 2010 800.

I bought some bolts, washers, and nuts from Napa and drilled the tunnel for the bolts. It was an easy mod that took me less than 1/2 hour to do. Looks so so but it does feel great, love the riding position now.

The fuel pump doesn't seem to be working properly when I went to start up it for the first time.
I will likely pull it out and take it apart and clean it. If that doesn't do it I'll likely go to eBay for another one.

Still no snow here in Colorado foothills but just a matter of time so I want to get this baby going soon.

Looks good!

Get a rebuild kit for the fuel pump. Should be around $10. Most local powersports dealers will have it in stock. Just bring the pump with you to the parts counter. It's usually just 3 membranes that go into the pump housing. Also, replace your impulse line. 1/4" automotive fuel line will do the trick. If it's old or cracked, it'll cause hard starting issues.
