I don't run injection because it gives the Quad a cleaner look and I don't have to worry about something on a woods trail snagging an injection line. It's fine to run it if you want but I would rather have less stuff to worry about.
I'm going back to the yamaha "auto lube" oil injection! Why? Because it works!!!
- Thread starter joeak47
- Start date
the tank never went dry. proper jets. well not really 2 pistons. more like 2 old pistons with new rings and hones.
I figured out that it was the oil pump because i turned the engine for a while with the output oil line off and into a bucket and no oil came out. started to premix and its been good ever since.
I don't flip my bike,but what you say makes sense... If the tank had a decent amount of oil in it,I doubt a bubble in the line would actually happen.
Reading all this talk about this pump and nylon gear never failing and lasting 24 yrs and thousands of miles is just amazeing. I believe i will go outside and put mine back on.
I am running the injector on my 98 and I like it. My sons Predator 90 and PW 80 are also injected. It makes it much easier to keep them all the same. I am not about to fool with the injectors on all of the bikes we own. When I get to fixing my 01 I am going to jut the injection system back on that one, the only reason it is missing is the PO took it off. I am with Joe on this one. IMO the system is safe, reliable and easy to maintain. Before every ride I check the tire pressures, oil levels and fill them up with fuel.
lmfao!!!!! If you ride quads and ride hard in the slightest, or ride trails that are fun in any way, shape, or form you will roll over on occation. Or you don't "ride" but i guess "never rolling over" could be possible in a completely boring universe.
All of us here know the oil injection system works but it has it's flaws. And that is why we delete them. Peace of mind is worth more than anything when you are pushing these little motors to their limits.
But I asked a question here and didn't get an answer. I asked what do you do if you roll over and are unable to get the quad upright for a few minutes? How can you be 100% sure that oil is going to be getting to the motor after the roll over? I'm not asking this to be a smart ass but so riders who do use the injection system know what to do if this occurs
Nothing amazing about it. Facts is facts. Its a system that works VERY WELL!
Everybody gets sucked into the rumor mill crap,because they hear bull sh#t like the following...
"My brothers uncle's next door buddy has a friend,that has a friend,who knows a guy,that lives in the garage attic at his grand mothers house,that had the "Auto Lube" pump fail on his yamaha blaster after he swaped out the blaster's stock cam shaft for a 3/4 drag race cam and dual carbs"
OR...
"Do you know Nick's friend named bob that knows the factory drag race guy that worked for ford for two weeks in the off season? Well, He removed the "Auto Lube" injection pump from his yamaha blaster and gained like 11 1/2 more horse power,because of all the drag that pump places on the engine. Get rid of it! They break all the time anyway."
Or...
Lots of threads like this on the blaster forum >>> (with total disreguard for the "search" tab)....... Typical question..... "I need help... I have an 89 blaster that won't start and run. Whats wrong with my blaster???
(No mention that its has fuel still sitting in the tank for the last 21 years,a fouled plug, and its been sitting outside the whole time.) ANSWER >>> Get rid of that oil "Auto Lube" oil injection system. Thats your problem. They just go bad and break all the time."
All the negative stories I hear about The "Auto Lube" oil injection system on yamaha blasters crack me up! I love how total ignorance about a system or object makes your average person "assume" and then blame that system for the problem,when in "Reality" its something else,or a combination of something else that caused the issue.
People are funny.
Like I said before... If I raced on a track,or was building a custom blaster, or not going very far from where the fuel is,there is no way in hell I would have that "Auto Lube" oil injection system on my bike. No need for it.
For all other reasons.....You'll wonder why you took it off in the first place. Seriously.
Sounds like alot of blaster owners as well after reading all the threads about JB weld repairs on read cages,cases,and rubber intake manifolds.High temp silicone sealant being used on gaskets...especially head gaskets and intake gaskets where fuel disolves it, gluing things back together,duct tape,and electrical tape repairs,etc,etc.
you must be reading some old stuff. the search function has a lot of flaws in my book. And if a current thread came through like that it would be attacked by the members who actually try to build these bikes properly
Old stuff or not, its out there. Blows my mind how "some" people treat and repair they're blasters. I'm sure its the exception to the rule. Or... maybe not.
Sounds like its time to make a video on how the "Auto Lube" injection system works on the blaster to dispell the myths. I:I
well let's see if we can put so much good information out there we bury the bad.
Now can i have an answer to my question about what to do after a roll over on the trail? and let's pretend we have a half full oil tank a screw driver and a pair of pliars(which is the minimum tools anyone should carry when riding)

Absolutely... But,put the pliers away,you won't need them. Here we go >>> Remove the the four screws that hold on the oil pump cover,remove the bleed screw,let any air bubbles excape the bleed hole until you get a solid flow of oil,re-install the bleed screw,re-install the pump cover,inspect yourself and your blaster for any damages,then... GO RIDE!
I almost forgot...Don't forget to put your screw driver back in the tool kit.
Thank you.
Now was that so hard. lmao
I ask bc i have never had the oil injection on my blaster so i have never had to fiddle with it. And as you have read here most guys don't know what they are doing when it comes to working on engines.

well okay as i see it. if you have air in the lines and a half tank of oil. and you have no spare oil and you are out in the trail for a pretty long ride with your buddy's and this happens and you fully bleed the system correct i takes oil from that half a tank of oil to bleed the system and you oil gets low your light comes on then end up having to be towed back to camp or where ever you where going? i would rather just premix and not have to worry about all that.
After reading your comment,its safe to say that you have never bled an "Auto Lube" sytem on a blaster.
About the maximum you will have to bleed is a table spoon or two...maybe three. Its actually very little oil that needs to be bled. PLUS... That half tank of oil left is still good for about two tanks of fuel,or perhaps a little less depending if your riding on the needle,or riding on the jet,so you will run out of fuel LONG BEFORE you run out of the oil.
So....... Your buddy would be towing you back because you ran out of FUEL not oil. Then when you get back to "base camp" you fill up with fuel,AND then you would fill up the oil tank. Simple.
You can always carry a small bottle of oil under the seat next to the tool kit if you feel the need.
i have never messed with the auto lube system. always have premixed. but my buddy has the autolube and he wishes he would of premixed from the first time he rebuilt it. he just blew his up again and turned around to be the autolude system failure. as he tears into it more i will try to get some pics of what happend.After reading your comment,its safe to say that you have never bled an "Auto Lube" sytem on a blaster.

Thats sounds pretty accurate and strait forward to me... No personal experience of it failing. Just alot of rumors,and "he said she said",or assumptions that it was the "Auto Lube" system that caused they're problems.
