EPI arrived today, Much beefier tool with a much shorter snout. Thanks for the tip.

Difference between reverse and non reverse models? About those years it became standard equipment instead of an option. Who makes the bearings? Yamaha usually uses NTN Japanese bearings. About as good as they get.

Why zero weight is my only question? 10 weight is good to -40 f and 5 weight to -65 f. I lived in Fairbanks in the 70's and at -59 had no problems with 10-30. Yamaha called for 5-30 in the Apex in 2008, and the motors haven't changed any. And I don't believe for a minute that yamalube is...

Phazer filter is bigger than the Apex, just put them both on. Must be more than a few different ones.

EPI is on order, thanks guys.

No, just keep the holes covered up and the key pulled.

EPI only shows one for Yamaha, # PCP-6 All YPZ/YXRC clutches. Is it the correct one? http://www.erlandsonperformance.com/mm5 ... owyamtools

Sounds like the oil rings collapsed from the heat. Pull a compression check. If it's good you can run it but expect fouled plugs. The only other thing that would cause it would be valve guides and they usually smoke on start up and deceleration the worst. You did change the oil I hope.

I bought a puller off ebay (parts unlimited brand) and it buckled the thin part and button headed the end, never budged the primary. As it was buckling I thought the primary was coming. No damage to anything but the tool. What brand do you guys use?

found this today: http://www.snowestonline.com/forum/arch ... 19191.html Whhhaaattss up Loui. Once he pulls the motor down to work on it the head will be off and timing done etc so it's the best time to put in the manual tensioner. The benefit to the manual tensioner is that you set the...

If you freeze up a throttle cable you'll wish it was there. There is a vid of a guy that had his disconnected and the sled took off at mach 4 with out him. It found a tree about 100 yards later. It's just a switch that goes to a rev limiter circuit in the ECU.

Snow, kinda covers things up around here. We usually can't even see our tail lites.

I don't think it is hydraulic. The oil dampens the load. The spring should hold it. If it were me I would talk to a Yamaha tech before taking the chance. Little slow around here as season is over with.

It's mobile 1 synthetic. Bought it local at a fuel supply that is a mobil dealer. Check with your local airport fuel supplier. You can use the stuff on the clutch as well. Much better lubricant than the beacon and shell and is fine at low temps. -40 to 350 f. Enough they can lube planes...

On the Apex: Put in Scotts steering bushings, mobile 1 grease, super smooth! changed oil and filter, set the toe, (poked it down a tree well late in the season) Sprayed the motor down with silicon. Should have it wrapped up tomorrow except for the clutches. Still have to build the tools for...

I am sure it is oil dampened, the new ones are hydraulic in 2011 or 2012 I believe. The manual says to bleed all the oil out before installing so the spring must do the job. A spring would bounce all over without oil in it and wear out quick. They can only be cycled so many times. Just as...

I haven't done one of these motors yet so I just can't say. I would be asking the same questions. Now I see why you said the rub block in the valve cover is going to hold it down. I think you are right and everything is ok. It's not actually jumping. Pretty experienced group here someone will...

Re: oil My thoughts too? And all engines burn oil or they would burn the rings up. Most engines burn it at a slow enough rate that the contaminates being added to the oil make up the difference on the dipstick. It doesn't take much thought to see there has to be some oil on the cylinder...

You said in your other thread this engine was new to you. Did you replace the gears, chain and tensioner or is this the old stuff? Even the vector has the nytro style tensioner now I believe. The older ones were different. I wouldn't start it either until the problem is resolved. Might be a...

Just finished the wife's Phazer. Time to put it out to pasture and pull the Apex in for it's going over.
