fuel ratio

all my bikes have oil pumps removed and i run premix

That sounds totally retarded to me, but what do I know. The oil pump supplies oil during closed throttle operations. It's a brilliant 2-stroke idea that's even used in 2-stroke ultralight airplanes, so your engine doesn't seize during part-throttle descents. So why would anybody remove the engine-saving oil pump from a 2-stroke scooter? It's like going back to the 1930's. So convince me . . . show me that you know more than Honda-san about oil pumps.

read up on how a two stroke motor really works ever hear of the Yamaha banshee which happens to have been the fastest production quad out years ago and its premix.... Honda put oil pumps on to make it so anyone can ride with out knowing how to mix the gas... if it did hurt the motor bear would have already yelled at me and many others for it.... so do a lil research

Not true. Oil injection came about because way to many nitwits would either use the wrong premix ratio or forget the oil altogether. Oh and Honda wasn't the only one to go with oil injection, almost all quality manufactures went to it except on race machines. Nobody ever said premix hurt the motor, it just is a colossal PIA. *, when I first started to play with 2 strokes, NOBODY had oil injection, everyone had to premix and that was at 25 to 1.

i know bear i didn't mean it like that i know better to argue with you over the oil pump so i'am not going there, but that jj said that it would hurt the motor cause there is no oil going to the cylinder with no throttle.... also almost everything 2 stroke like dirtbike, atv, atc, and even some push grass cutters run on premix even after the invention of an oil pump.... so whats the reason Honda never put an oil pump on there 2 stroke dirtbikes guys???

We're talking about Sprees & Elites, not Yamaha Banshees! The Banshee is an unlicensed "bush tractor", not a scooter for going to work in traffic every day. Yamaha left off the oil pump to make it cheap. Who knows, maybe you can take time off school or work to replace seized pistons but the rest of us can't play around like that. Taking the oil pump out of a 2-stroke scooter and running on pre-mix is like a step back to the previous century. Who needs to do that?

So does premix

so your engine doesn't seize during part-throttle descents.
That is not why oil pumps were invented

So why would anybody remove the engine-saving oil pump from a 2-stroke scooter?
To choose a different oil gas ratio. The stock oil pump is 70:1 (not enough for bigger bores)

And my response is why remove the oil pump when all you have to do to run more oil is add a little to you fuel and with the small amount needed to reach 32:1 you won't need to rejet. You guys make it much harder than it needs to be.

bear no disrespect but thats not what where talking about right now, we are talking about a person who doesn't know anything about how a 2 stroke motor works, we understand why you believe we should keep the oil pump.... not the case here he's saying you can't run premix on a engine used for on road use because it will destroy the setup.... complete b.s. by the way my 43mph spree runs premix all day everyday and i mean everyday, i put over 2000 miles on it with the PREMIX setup with NO problems DO SOME RESEARCH BEFORE YOU OPEN YOUR MOUTH!

If premix worked for many decades before injection arrived and still works for racing, why the * would it not still work for street riding? How could there ever be a question of that. Where the * do the engineers test their new ideas, on the race track that's where, but that was not the original question.

I hope to * you are not telling me to do my research before I open my mouth, because you need to back up a step and rethink your position.

[fastplastic]

.....and if you did do your research you would find that company's where making premix motors up into the 2000's so that 1930's technology crap your trying to push is bull..... company's that build the motors make them to take all sorts of abuse and believe that premix is the best setup to run not to "cheapen" up the bike but to make it do what its meant for and much more...... what happens if you don't put enough oil in your premix you will blow it up, what happens if you don't but oil in your oil tank you blow up not cause one is injected and ones not......

I WOULD NEVER TELL YOU THAT, you know your stuff i just trying to correct that jj guy who doesn't get it

[Bear45-70]

OK and I agree with you on that issue.

I don't get it. Why are you using premix if your Elite has an oil pump? It's not a chainsaw.

I am just answering the original question of why some people do this.

I don't recommend this for everyone.

[fastplastic]

ok best way i can say this is premix if you choose to run it will work perfectly fine as long the oil mixture is right both on and off road use the reason i run it is believe it or not for convince because i have weed whackers and such that run on it, make five gallons use it for everything.... have i been caught with my "pants down" at a gas station yes, but do i regret running premix no... "MY OPINION"

[Trafficjamz]

If honda made a variable oil pump that could deliver oil to the fuel at a ratio of 70:1 - 25:1, I would run it.

But they don't ,so I mix.
