Oil injection question??

[lukewozniak2000]

I was wondering how reliable the oil injection is on the blaster. I have been getting alot of mixed reviews by reading different threads.... please someone sort this out for me. I know the block of kit is great with no worries but i just dont mess around with it. I know its worth the money but would the oil injection be just as fine or is there many problems with it. Please someone give me some answers on this.

Thanks:

Personally, I like the peace of mind of mixing my own fuel. I know it will be spot on right how I want it.

They can last and they can go, I'd take it off asap though, but that's just me. They can go and your engine will be getting no oil at all and you'll be seized within ten meters of starting it up. I know of several people who have got there hands on a clean blasty only to seize it the next day.

Its true... Oil injection on a Blaster engine is hit-and-miss. It works fine in a perfect world and on paper, but all it takes is a air bubble in the line or a broken pump drive gear, or a disconnected/clogged oil line to screw things up. I don't trust it. A blockoff kit is money well-spent.

This being said, there are two sides to every story. My wife's '97 Polaris Trailboss 250 is bone-stock and has never even had the carburetor opened up from the factory. It's VRO (Variable-Rate Oil Injection) system works like a charm and I've never had any trouble with it. Throw in some oil every couple fuel fill-up's, and keep on motoring. Though that engine has a direct-drive oil pump, not one driven via a gear such as on the Blaster, so it is more trustworthy.

the problem with the oil pump,if the nylon gear fails,theres no way to tell unless you pull the clutch cover off,and by the time you think of checking it youve already blown the engine up.Much safer to pull the pump and pre mix your fuel.

we have yet to see a pic of a failed pump gear on here, correct me if i'm wrong ????? and pics or your lying !!!!!!!!!!!!!

i ran my brand new '96 for 8 very hard years, sold it with good compression on the stock piston and oil injection still working flawlessly
until i see a proven pic of a failed gear, this is just a myth in my book, and the oil injection gets blamed for other rider maintenance issues, such as.... disregarding the low oil warning light, letting it run dry, letting dirt get into the resivour while refilling, junk weedeater oil, improper warm-ups, air leaks, ect, ect. ect.
but the pump always gets blamed, i say prove it !!!!!!

BTW, neither of my current bikes run the oil injection system, one was already removed, and one was in horribly dirty condition, but i sure miss the ease of it, and don't know if i recommend it on a modded motor

My mechanic explained the whole thing to me. There is a plastic gear in the oil injection that just isn't reliable. Just buy an oil injection block off kit. It will be well worth the money.

i also just noticed, while surfing ebay, that the banshee water pump uses the same plastic gear as our oil injection, does the banshee water pump have the "fail" reputation that our oil pump gear gets ??????
if so, i've never heard it

To save a few $ you can disable the oil injection system rather than buying the removal kit. The downside to the 'quick disable method' is the plastic gear is still inside the motor and could eventually break apart.

Also, my understanding is the stock oiling system mixes ~ 20:1, whereas now that I've disabled my oiling system I'm premixing to the recommended 32:1 and my throttle action is more crisp (less boggy) than prior to the removal.

cant you just take the gear off? i did... and the plastic gears on the banshee water pumps are known to fail and thats why they make billet gear and impeller. if its working fine and you dont wanna remove it dont but if you motor goes boom out of nowhere be sure and check it before you fire it up the next time.

yes you can do that aswell
