Does anyone know the differences between the Phazer 1 and 2's. I think i have figured out a few things but wanted some insight from people who have had both. I currently have an 88 Phazer 1 and i just purchased a 90 Phazer 2. I think the track is a 121" track instead of the 116" track and the ski stance appears to be about 2.5 inches wider. Was there any upgrades to the front suspension besides being wider. Also are there any other upgrades to the rear suspension. Also curious if there were any changes to the motor or clutching. Any input would be greatly appreciated.

Thanks for the input

you figured out the obvious.

skid is the same, just longer rails.

clutch changes came a few years later.

in addition to the wider stance, the arms and scissors are reconfigured, as are the struts. front plastics wont interchange.

pzII's had different skis but they will interchange.

somewhere in that 90-91 range they went to a plate style stator vs the individual coils in the pz1's.

engine, drivetrain, carbs, clutching(for the most part), etc were all the same and parts will interchange.

Phaze

Is were 480cc and the IIs 485cc. Minor detail.........

actually they were all 485's. why yamaha sold themselves short on those 5cc's is beyond me, especially in such a competitive market where bigger is better. look at the base of any pz jug, 84-98 and its stamped 485cm3.

Is the stator change a good or bad thing. This sled I bought is immaculate. The only thing wrong is that it has a locked up motor. I'm hoping that the jug isn't tore up too bad and a new set of pistons and rings will have it going. I guess I'll keep my fingers crossed. Couldn't pass up the deal though. 250 bucks for the shape this thing is in was great I thought. I guess if the motor has a messed up crank I won't be so lucky. I keep ya posted.

Interesting. I did not know that. I guess because they were documented as 480s.

Ok a couple other things I noticed after some more looking. The brake caliper looks different than my 88.

The voltage regulator (I think that is what it is called) is located where the battery would be, not electric start sled.

The rear skid has an upper shaft with 2 little bogey wheels that my 88 also don't have.

The primary clutch has a different cover on it. It is more open. Is it just the same just a different cover.

Thanks again. Sorry for all the rambling.

the ignition change is neither good nor bad in my opinion and it should interchange.

the upper crosshaft was added with the 121 track, forgot about that.

you will also find some subtle differences in the wiring harness. in addition to the regulator, the heated grips also have different wiring.

the clutch did change a bit somewhere down the line, thought it was later. some of the internals were changed.

unaware of brake caliper differences, i would have to compare. pull rope routing was a bit different as i recall.

pull that thing apart and see whats up. crank repair can be spendy, hope thats not the case.

According to the seller it was running fine and then it started to loose power, he parked it and now it is locked up. I looked in the spark plug holes and it appears that the clutch side cylinder has some scaring. Doesn't look too bad though. I'm hoping its just a stuck piston. Some boring and pistons and rings....hopefully

Drop some 2cycle oil through the spark plug hole and let it sit for a day and try to turn it over by spinning the clutch by hand, if it isnt melted to the cylinder that is

And then there is the Phazer 500 from like 99-00! And it is Still a 485! And the only change I see is something in the head or the shroud?

Just a recommendation,,on all these sleds that drive the tach off of the oil pump....do yourself a favor and pull the tach cable out and make sure it turns freely. That little cable cost me a bunch of money (crank rebuild) because when it siezes it takes out the brass pump drive gear and you are left with NO lube. If there is no other significant damage and the oil pump drive is gone you can premix the fuel and perhaps run it for this winter and get some fun out of it. Good luck!

Ok update time. Pulled heads off an it appears the clutch side piston is missing some of the ring and the cylinder wall is scraped up(hopefully not to far though). The piston isn't stuck though. I found some small metal shavings in the exhaust manifold and some real small ones on the piston. The clutch side is down below the start of the exhaust port. Is it still possible that the ring would stick that far down. It won't pull over at all. Seems to be stuck solid. I will be working on it some more later. I'm going to go ahead and pull the motor before I take the jugs off. Easier on the back on the bench.

bent rod?

Ok now I got the jugs apart and the clutch side piston is trashed. See photo. The piston skirt on one side is gone. I still need to split the case to see how many pieces are in there. How do I find out if I have a tweaked rod or bent crank. I'm kinda scared now how bad this might get.

I had this happen years ago on an 89 Phazer and it was a clutch side main seal causing clutch side piston to run really lean and hot. It sounds like you got some shavings down in a rod bearing if it still wont turn over with the jugs off.
