Very true. If the premix oil injection system fails (other than just not putting premix in), it's really obvious and doesn't lead to any engine damage.

The problem with doing that is that 2-stroke oil is supposed to be mixed in with the gas, not just injected in seperately. Wouldn't it get vaporized before it could lubricate all the engine?

 

i wish there was a way to convert the s5 mop to a s4, my reasoning behind this is im betting the s4 one is more liberal with how much oil it injects (when the throttle body opens it yanks the mop open)and the more oil the longer the engine will run. the s5 one takes into account alot of info and injects based on that but for better emmissions it limits the oil injected compared to the s4. also the s5 one is almost a reason to sell a car b/c when it goes bad like mine did it will fry the ecu and set you back quite a bit of money to replace the two items. without the proper resources you could end up paying almost 1500 bucks to replace those at the dealer...

 

i know i read this in some place in this web site that there is something u can use to clean up the carbon build up but that is like a last thing u want to try cuz it can **** up ur seals or something like that. why is carbon build up so bad? i know it robs power and stuff i have seen it kill more then half the power on a piston engine but we just added something called engine restorer and it clean it up good

 

Carbon buildup on a rotary is particularly bad for a few reasons.

1. It increases compression. This is good, except increased compression increases the risk of detonation. Detonation kills a rotary.
2. It can come off. A chunk of carbon coming loose inside a boinger *usually* doesn't do much damage, if any. It rattles around until it breaks up and heads out the exhaust valve. In a rotary, there's a much greater chance of it getting wedged somewhere, and ripping up an apex seal. Rebuild time.

The only one I'd try is the water trick.
