It has an electric starter on mag end. There is a hole in the center of the cover plate above the starter that appears to be for the oil pump drive shaft. This engine I purchased new in 1994 and it has never had an oil injection installed on it. There are no holes for the injection in the intake manifolds. I am wondering how big a job it is and what parts I need and where to find them. -------- Tom Jones Classic IV 503 Rotax, 72 inch Two blade Warp Ellensburg, WA Read this topic online here: http://forums.matronics.com/viewtopic.php?p=276556#276556 ________________________________ Message 2 _____________________________________ Time: 06:48:17 AM PST US From: Blumax008@aol.com Subject: Re: RotaxEngines-List: 503 oil injection retrofit In a message dated 12/7/2009 9:12:57 A.M.

Take it from an old hand (very old hand) at ultralights & 2-sicle motors...DO NOT install an oil drive system. Keep mixing your fuel & oil. It's much more reliable & a hell of a lot less trouble. You're just asking for trouble.

For those who use these products here are the top two out of 11 that actually do some of what they claim. Tested by an independent lab. Both the Nulon Pro Strength and the NF Racing Formula rated the best octane boosters in our test. And considering that less NF was needed than Nulon, it evens out a little with a slightly higher cost. Still, both proved extremely effective at increasing octane, even outranking Toluene, which needs much higher levels of concentration. 1st NF Octane Booster Racing Formula 250 ml treats 80 litres RRP: $29.95 Octane Improvement: 99.6 (+2.8 RON) An Australian-made product from Perth, the NF Octane Booster Racing Formula was the smallest bottle in the field, but looking at the mixing ratio, also the strongest relying on an incredibly small dose a mere 3 percent! Claiming to increase octane as much as 6.0 RON , NF took the gold medal in a surprising tie. If it were a split decision based on concentration though, it would be the clear winner. 1st Nulon Pro Strength Octane Booster 500 ml treats 60 litres RRP: $20.95 Octane Improvement: 99.6 (+2.8 RON) The Australian-made Nulon Pro Strength Octane Booster is the top of the range Nulon fuel product, claiming to boost octane up to seven number. The Pro Strength gained a joint gold-medal equalling NFs 2.8RON increase. To conduct these tests we contracted independent laboratory Intertek Testing Services, who would test our products on a knock engine. We also had to find a base fuel to add our boosters to so we went to the closest public petrol station, which happened to be Shell. -------- Roger Lee Tucson, Az.
