Re: Reducing Vibrations at High Speeds.
These little engines can get pretty hot so I don't want to take off the fan and shroud though that would give a little more HP to turn the bike wheels. I plan on fabricating a better mounting plate to put the engine on and some rubber mounts between the engine and plate. The drawing Neat Times posted awhile back is pretty much what I had in mind between the plate and engine. I had a similar mount on a 65hp Rotax in my home built Avid Flyer airplane which did a good job reducing the high frequency vibes from the engine.
