facthunter Posted May 1, 2007 Share Posted May 1, 2007 BMW Powerplant. There's a factory produced unit available. Can't give you the website, but if i could find it, anybody could. Horsepower was fairly high ,but it wasn't particularly light or cheap.Think it was available in U.K. Hope this helps N... Link to comment Share on other sites More sharing options...

Guest danda Posted May 1, 2007 Share Posted May 1, 2007 Give this site ago http://shayaviation.com/conversion.htm There is a big concern and that is that the A/C is made for 80hp max and I think the BMW is 100hp could be a big problem.

eastmeg2 Posted May 1, 2007 Share Posted May 1, 2007 I recall reading an article several years back of a trike with a BMW bike engine converted for Aero use. That article included a story of an engine outage due to the battery going flat, so I assume these engines cannot run when the battery goes flat or gets disconnected unlike what I've seen on Rotax 582's where the ignition circuit is independant of battery power. Has this all been rectified since then? Link to comment Share on other sites More sharing options...
facthunter Posted May 1, 2007 Share Posted May 1, 2007 BMW.Donk. Would the HKS twin be worth a look? I've done quite a few hours behind one in a skyranger. Needs high octane fuel. It's smooth and light & not too noisy. Just under 60 horsepower..N... Link to comment Share on other sites More sharing options...
Guest Crezzi Posted May 1, 2007 Share Posted May 1, 2007 I recall reading an article several years back of a trike with a BMW bike engine converted for Aero use. There is at least one I know of in the UK - its a Huntwing which is a kit build. Like here, most UK trikes are factory built hence the rules prevent fitting different engines. See http://www.huntwing.co.uk/ Cheers John Link to comment Share on other sites More sharing options...

geoffreywh Posted May 3, 2007 Share Posted May 3, 2007 I worked on BMW R1100/1150 engines for years, they are brilliant, only trouble they ever gave was with police models where they would leave them idling for hours at the scene of accidents to keep lights flashing ect. I had to replace a crash damaged c'case once on a 100,000 km travelled bike, very little wear anywhere. Ask K & R motorcycles in Melbourne for durability advice, oils/filters ect. The UK BMW people look to have all the good ideas. Link to comment Share on other sites More sharing options...
