Yes there is a block off kit available through High Performance Designs, Inc .

I know the "VOICES" aren't real but they have some great ideas.

I don't understand the purpose for doing this. Can't be weight savings. All it does is foul up a gas can. What am I missing???

'96 Xplorer 300 Aftermarket CDI box, K&N filter, jet kit, reworked expansion chamber from dirt bike, 1" taller + 1" wider rear tires, dual wenches, Rack on rear/w cargo pac, polaris box on front, Mossy Oak cover on seat, back-up lights on rear, aux. power source for GPS,"Theft deturent's", hand protectors, new clutch springs coming! Would love to find GURU style bumpers! By the way, I'm also a graduate of AMI with over 20 years of motorcycle mechanical experiance. New to quads, but the same basic engines. 2 stroke or 4 stroke!

If the fuel is already pre-mixed there is no chance of an oil pump failure or clogged filter destroying the engine.

I don't get why everyone is so against the OI systems on these quads. I can't seem to find a lot of actual people who have had a failure that resulted in a seized motor just a lot of people saying that it COULD happen.

Oil injection is very common in the 2-stroke snowmachine crowd without issue. I have several snowmachines that are in the 15-20yo range that still use the factory OI setup without issue.

What is so wrong with the OI on the quads?

Im not sure how they work on sleds, but Ive had them fail on dirt bikes and ATVs. They were all Japanese engines though. They are notorious to fail on the Yamaha blasters and tri motos. It also ended the life of an old TS250 I had.

Premix is FAR better for engine life as well as power production.

I deleted mine from fear that it wouldn't be able to keep up. I have too much invested in my machine for a simple failure like this to ruin it. Also, getting rid of the second leg of the throttle cable gave me a little better throttle response and since I ran snorkels up the center I was left looking for a place to mount my reservoir. HOWEVER, I encourage anyone running a fairly stock setup to keep it because they ARE reliable on these machines.

I had too much $$$ into my 400 porting, etc to risk an oil injection failure, so I eliminated mine as well.

Also, if you eliminate the oil injection, make sure you get a new throttle cable. The OEM cable has a splitter on it and it can get jammed when not connected to the oil injection and cause the throttle to stick.

Ritter Cycle has them for $19.99.
