04 viper ER oil consumption questions???

i dont know daman marine motors are proped to a specific rpm, like sleds are clutch weighted to a specific rpm, and there both are varied, the only thing i would say is the marine motor goes from wot to idle more than the average sled motor, but the sled has a little higher wot rpm, i just dont think there that different. and the Etec uses less oil because its put in the bottom of the motor and lubes the bearings ect. and there is no fuel there to dillute it so you dont need as much
 
as for the 50:1 ratio to check fuel against oil would be pretty hard seeing that the pump is varyable wot maybe 50:1 but idle may be 150:1 ? i would think if you did that measurement, fuel/oil used and it came to 50:1 you would be fat on oil unless you had it wide open for that tank of gas, i mean one of the reasons for oil injection was to improve performance by varying oil to throttle opening
 
There is a difference that's why theres two different specs one for marine operated and one for traditional operated 2 strokes. marine use engines needs different spec'd oil,why? because there operated in a totally different way. read my post here it's along the lines of what were talking




yes it's been discussed here before about the variable out put on the Yamaha pumps, cc's will vary the 50:1 is an over all AVERAGE of what the pump is doing. thats the best we can do.

So what part of the average is crap?

Daman, Yamaha may not recommend 100:1 but in pre-mix applications (including my free air Yamahas), your beloved Amsoil did.

The whole point of discussing my success with lean oil ratios is that I and others have run lean ratios with quality oil WITHOUT issue. I can't speak to how long each bike lasted, but the '79 400 is still riden today. I can say they all ran great when I sold them as did my buddy's CRs (three I think).

My 12 year old junk eagerbeaver chainsaw still runs great. In fact the last Ryobi weedwacker I had was so lean on a/f out of the box that it wouldn't run right until fattening it with less oil.

Should Gary split the case on his Viper?

my beloved Amsoil? lol when did i become CEO,i use there oil because it's well built,i would never run there 100:1 saber what a joke, you want to use 100-200 300:1 go for it i could care less,have had it,not in my stuff.

anyway probably my last post everything that needed to be said has been said bottom line vipers need oil there's been plenty of posts in the past about vipers and bearing issues try a search,Yamaha had them too lean from factory.

Gary needs to get his sled closer to a 50:1 ratio. One must assume that his girl friend was on average lighter on the throttle. I agree that idle will be very light on oil consumption but WOT will be higher than 50:1.

Since their sleds traveled the same miles and terrain, and one must assume that Gary was harder on the throttle at times, he must make adjustments to use an "average" of 50:1 or there abouts. I am quite sure he did not idle 155 miles.

I would never buy a sled from someone who bragged how little oil they used no matter what brand of oil it was. There are so many Vipers that burned down last year that I never would knowingly use less than the recommended amount by Yamaha. I can afford $30 worth of oil per 700 miles traveled better than a rebuild during the season. Better to err on the side of safer.

Well I guess that settles it.

Gary, you'd better tear it down. Stop right now, tow it home. If it's been that way since day one it's a time bomb just ready to blow any day now. Bearings, crank, rods, pistons... oh, and rings too. Ah heck, just swap the entire mill for another, your's is junk.

Are you sure you've really got 3k on the odo? Surely you mistyped that or you're just flat out lying. Good thing you weren't using Amsoil since according to some here, it just can't happen. lol

Yeah, I'm done too.

Im not argueing that you could run on 100 ( or 126 to 1 in my case) nor BRAGGING that the sled has been running KLOTZ since it was new, and NOW HAS over 3500 miles on it with a mis adjusted oil pump control cable,,, but,,, it sure does seem that way.. the wifes sled is 1/4 inch different in adjustment than mine is!!! I really DO THINK i've found the problem.. I'll readjust it to HER SPEC ON HER SLED (and throw 12 ounces in MY TANK just in case) and take it out next weekend for a test ride!!!!!
 
Personally,, I'd rather burn TOO MUCH OIL than NOT ENOUGH!!!! i'd rather replace spark plugs than main bearings or motor parts!!!
 
The down side of going from 126:1 to a ratio of 50:! is you now are going to have to clean your power valves once in awhile!!!

LOL!

I'll bet those valves stayed mighty clean at 126:1!!

HER SLED used about 24 ounces of oil and around 10.1 gallons of fuel

Gary thats only 53.8:1 not bad close enought

MY SLED used 10 ounces of oil and about 9.6 gallons of fuel

that's 122.8:1 yea re adjust for sure.

what's free play on both these sleds????
 
I take the rubber protector off and pull the cable out of its seat all the way and measure the space between the end of the cable and its seat at the adjuster.. Thats how I come up with the 1/4 inch difference... maybe 3/16 in actuality,, but,, 1/4 inch for all practical purposes!!!
 
I'm going to take my wife for a little breakfast and then I will figure out BOTH BROKEN SLEDS!!!! Munising sure does beat up ME and the sleds!!!!

Of course the Yamaha sleds oil pump is variable, so the less amount of throttle being used, uses less oil and fuel. The more throttle more oil more fuel. this also pertains to rpm use also.

Is your wife outrunning you? lol just kidding. Al

Awwwww. That one was just below the belt!!!!
;)! ;)! ;)! ;)! ;)!
 
well, I just ground down a 1/4 inch drive socket to .795 which is pretty close to 20mm.. I measured 19mm around .755 and 21mm around 835.. So,, I did a little math and figured a 20mm equivalent would be about .795 ,,, I ground down a socket to fit... it fit FINE in the wifes sled ( around 56 to 1 ratio) and i adjusted mine to a TIGHT .795 ... Problem solved!!!! THANKS EVERYONE FOR ALL THE IMPUT!!! I also found the blown fuse,,,so I'm BACK on the saddle again!!!! Thanks!!!!
