Just wondering how reliable the oil injection systems are on the 250 2 strokes?
when i bought my quad it wasnt hooked up and it had mixed fuel in it, and since i hooked it back up it seems to leak a little bit and im just worried that its gonna fail on me when im out on a trail

And if i decide to just mix fuel, does it through off the carb at all?
thanks

 

I have read that they are very reliable. You can check it to make sure it is working before you ride it. I would never block off the injector on my Trailblazer. Why go through the extra work of premixing if I don't have to? Also, premixing lowers the octane of the gas quite a bit.

 

its rare to hear of the injection ever failing on these machines.

 

Oil injection on 2-strokes are reliable if you take care of them. Some people like myself took them for granted and it cost me $500 to rebuild the upper end. I never had any problems, just added oil when I need it. For some reason it quit working at 10,000 ft. and 7 miles from camp. When I removed the oil injection unit there was no blockage, filter was clean, oil was clean, and lines were clean. Got down to the plug that goes into the engine and it was plugged. I love my 2-stroke but I will premix from now on for all 2-strokes.

its just wat you prefer...the oil injectors work really good but for some reason i like runnign it premixed

 

can anyone explain in simple terms how it works - like is it some electric pulse type of thing that give a squirt every so many seconds or what

and does it give more at startup [like mine smokes more at startup]

 

The are ran by a gear . It runs richer at startup do to the oil settles in the bottom of the crank so when you start up it has more oil when cold. The oil is put in at differnt ratios by the throttle changes the amout that is injected.
