What is the engine ? The pros, will never worry about pump failure, broken drive gear/pin/belt, broken oil lines, faulty oil lever indicator causing engine failure. The only con and I could be wrong, if you running full throttle and go back to idle(quick) you might have a tad bit oil starvation when the engine is revving high and the carb is slapped closed to idle(remember your oil is coming from the fuel when mixed) This was a common problem on older dirt race bikes going flat out on the straights and throttling down on the turn then pegging the throttle out of the turn and BAM. Remember also these guys were running lean mixes for performance and the oil technology has come a long way since. So you should be fine. I'v convert all my "keepers" to premix. Never had issues yet. Depending on the engine, the pump removal/delete varies. The oil tank is your call, drain it, remove it, keep it for extra fuel, or iv seen a few keep it filled with oil with a manual shutoff and the drain out as need when filling up on the road vs having the container of oil under the seat. You will also have to block off any fittings that the oil lines went to for the injection or they will be vacuum leaks. As for marine oil, that's preference. I did run scooter on marine Yamalube for a year(injected) without issue. I personally wouldn't recommend it. My common sense tells me to run oils that are formulated to be used with air cooled engines. Marine engines run cooler then air cooled engines. Just my  Mina's/clones the down and dirty easy way is to just remove the plastic drive gear under the flywheel and leave everything else. Or remove the pump, lines, tank, ect. Honda's/Kymco's n/clones, you pull the pump and add a block off plug in the crank case, then tank, lines, ect. Piaggio bases engines and clones, I think most are belt driven so removal of the belt or pump, lines, tank, ect. FYI if you want to get rid of the pesky low oil light, just disconnect the plug from the float sensor on the oil tank(if keeping the tank), then it will always stay off(then again if you remove the tank this step is a given) Here is some light reading. 49ccscoot.proboards.com/thread/564/remove-oil-injection-system49ccscoot.proboards.com/thread/8671/oil-tank-delete |

its the 139qb or something? 139qmb would make it a 4 stroke. lol There would be no 2 stroke oil injector pump/tank/oil. |

That would be a 2 stroke, Minarelli(or Mina for short) or clone of one. |

Oil injection can sometimes feed the main bearings as well as the mixture, which by splash will get to the main bearings. If the mains are designed to get direct oil feed, splash feed will cause an early failure. Find out which you have. Marine 2 stroke oil is made for an engine that runs at lower temp than an air cooled engine. In an air cooled engine it may break down or create more ash and carbon.

I believe that there is good reason, if not clear evidence, that you should avoid using outboard 2 stroke oil. If you take the time and look at enough web sites, the answer becomes more apparent. I was involved in the lubricants business from manufacturing base stock lubricants. I have used Yamaha products for their quality...base stocks and additives. Yamaha currently sells only four 2-stroke oils. (2B, 2S, 2W and 2M). The formulations are actually quite complicated, but simply put...there are for 4 different engine categories for Yamaha. 2B- For competition engines of shorter stroke, high rpm 2S- For general use on land vehicles, both air and water cooled, pump or pre-mix. (Ding-ding-ding-ding) 2W- For personal watercraft engines with shorter stroke, high rpm 2M- For outboard engines with big bore, long stroke cranks. On Yamaha's website, they actually state "Not recommended for land based products, WaveRunner® or Sport Boats." While they do not say why exactly, just the history on these threads and possibly inferred technology, should be enough. I do know from experience, that the operating temperatures and friction coefficients have much to do with additive packages. In order to blend a proper lubricant, you must cover every part of the operating envelope. Clean burning, ash deposit resistant, surface metals protection, heat range...more. You cannot go wrong with a general use 2T oil, synthetic or semi. Besides, it is cheaper. Yamaha's formulations for PWC and Outboards are near 25% higher cost as an example. Part of that is fully synthetic base stocks, part from other "environmental" additives.  |

So, your saying use the 2b or 2s? Is it that simple- 2b pre-mix, 2s pump-injection?

Blip every dang where. It sounds cool and there is actually a point to doing it unlike on a 4t. 2nd worry for me is letting oil sit in pump gas for long periods. Pump gas has who knows what it in that can break stuff down. Have never had an issue so far knock on wood.. |
