Default Oil pump disable is "REQUIRED" according to Airsal... check this out! OOPS!

Okay...

I was cleaning out my box of old parts and ran into something interesting!

This came with my AIRSAL CYLINDER!

It says...

"IMPORTANT

If you change your carburator to a bigger one, please delete the lubrication pump. Use synthetic oil 3% to assure the right proportion of oil that your engine needs"

So apparently Lennox and his toasted cylinder and my damaged cylinder and a couple other ones out there! could have been saved if any of us would have read the little YELLOW ATTENTION slip in there! OOPS!

Anyway according to the above info if you install the Airsal cylinder and a carb... YOU MUST remove the oil pump and premix!

IMO a good idea and there is a simple to read and follow HOW TO in the HOW TO area listed in the blue bar above... look under "JERED'S HOW TO'S"....

I can only think of benefits with the oil pump disable, less drag on the engine,and the fact you know your mixture is right.

Most of us remove the gear at least to reduce drag on the crank. I dont physically remove the pump from the scoot though.

not to reduce drag... simply to keep the pump from running without oil in it and burning the oil pump up in case of needing it in the future!

Well, the law states that these mods are illegal, and should be used for racing purposes only. The pipe isn't approved for use, and is illegal in the noise department. I also had the little T-6 paper about removing the oil pump. If somebody can tell me that they can see, hear or feel the drag difference on that little oil pump, let me know. Premix can give you a consistent mixture ratio, but those pumps are on some extremely hi-performance snowmobiles I've seen. These sleds also have a type of 2 stroke fuel injection, and it hasn't affected them. Like jered stated, to each his own.

Its not like its going to affect warranty

Unless someone complains, no one will care about them as they are not as loud as harleys... which with the loud pipes ARE ILLEGAL TOO!

Stock Harleys are not loud... it's the screaming eagle and other pipes that make them that way...

What do you mean its not your opinion, YOU stated "still saying to each their own... but the cylinder manufacturer says to remove it.... Can't argue!

Didn't say anything about Harleys, (or car stereos, or other loud things). I made a more broad generalization about the subject beyond noise.

Str8dum, not worried about the cops, or my oil pump. But answer my post, how much power have you gained by removing the pump and reducing drag.......

my post was in jest. as leaving the pump on there wont burn it up either.
However, no reason to have soemthing else spinning off the crank if you are not using it, now is there? Its just called being anal.

I dont understand what you are tryin to argue or what the relevance of your previous post even had to this thread?

Geez str8, I didn't realize a pump left in place was anal. You state twice now it reduces drag.

The rest of the post was in response to jered. He can pm me, or just leave it, its just a post. IF you don't like it, don't respond or read it, its that simple

Yes something not spinning on the crank reduces drag. That simple. How much, who cares. I never claimed any increase in crank rpm. You called me out by name. I just answered your post. Very simple to understand. Argue that.

why cant you run the pump and put like a cap full of oil in the gas when you fill up. that should be enough oil to run it.

Realistically, the pump is probably fine. at 300$ a cylinder, i;d rather err on the safe side. But i guess as long as you jet considering the unknwn amounts of oil leaning out your mixture at 13, 14000 rpms you'll be safe. Thats a big unknown.
But still we are just basically chatting around the central theme that its up to your comfort level.

Which MHR cylinder do you have? single piece head or modular?

it really doesn't matter!

do what you want... if your scooter goes faster due to less drag... then cool... or you prefer to premix or inject...

it's all your own preference, you have to live with what you do... so to each their own!

my zuma is a 2000 so malossi only has the aircooled mhr bore kit 68cc for that bike, but when i switch over to the laydown minarelli engine i am goin with the polini evo watercooled that does have the modular head. also i have a friend out here that is running a complete polini evo set up with a kundo rotor kit and he is running the injector and his bike runs like a champ.

I have done both on this kits and so far neither has lasted more then two weeks maybe i am not filing chamber ports enough or not breaking them in right. first kit was with the 21mm Spanish carb ran fine for 1 week and 3 days, the other kit was with stock carb because for some reason while waiting on new kit my carb quite work the needle would not move up and down any more in the carb (if i put the cylinder part in that holds needle, upside down it will travel up and down smooth put in the right way will not travel down more then half way forceful )

Well.....if you don't Jet properly...you will seize.
Goodness gracious.....
If you put oil in the tank, you must upjet since you are technically leaning out the mixture since less gas goes through the jet, since the thicker oil molecules are "crowding" it when the fuel flows through. If you are going to add oil to the tank then you should upjet a size or two based on that alone.
