    whats the chance of doing serious damage to your motor if your bike falls over. I have A full suspension mtb bike.Im thinking about it but ill nock it over just as shore as s#%*.

    I recently broke my carb off (HT setup). Bike fell over while on its stand (the ice under the kick stand melted over the course of a few hours). It was standing beside a big block of wood, the carb hit the block when the bike fell and broke the intake manifold. I had to "rough it" for a few days with a piece of hose holding the intake together.

    On a rack mount I suppose you could do some damage to the pull start or anything else protruding from the side.

    The bigger the engine & the higher it's mounted on the bike the more likely it is to sustain damage if the bike falls over.

    I think most "quality" compact engines should be fairly resilient to the force of a "small" fall. Most chainsaws, weedwhackers etc. are.

    As a specialist in breaking pig-iron kickstands on an overloaded Red Rocinante, 30 mph wind gusts hitting the bulky windshield on a parked recumbent Rucio, my bikes have tipped over at least 50 times....the handlebars hit first, and luckily I haven't broken but one mirror.

    If you "tip over" at 30 mph, engine damage is the least of your worries.

    But take the protective housing off of that chainsaw or weedwhacker engine and drop it.

    You know those strange looking bars like hoops around the front of some Harleys. Don't know if they origionally were a bike-fall-over protective devise. But, that is what I have in mind. Only on back.

    Those strange things are called crash bars or engine guards. Protection from tip overs and low side crashes.

    On a tippy rack mount motored bike, maybe a just simple bar extending a little past any engine bits would work. Maybe it could double as a tie down point for small items?

    4 different GEBE's that i know have fallen over once or twice...not from imbalance, we use the greenfield stabilizer rear kick-stand on the stock bikes...but a coupla slow fall-overs and a few crashes at speed...there's never been any damage beyond cosmetic with our quality engines, and the 2-strokes usually keep running too.

    i considered incorporating crash-bars into my rear rack, decided against as overkill, but hope i'm not sorry once i'm out there on the road.

    Ive had my HT mb fall over a few times when idling and resting on its stand and everytime it has continued to run bar one time when the clutch must have released and the back wheel touched the house it was leaning against.

    Saddlebags, paniers or "off to the sides" basketry would serve dual purpose, carrying stuff and protecting the engine.

    Just like a M/C you dont let them fall over. Stuff happens though thats why they make replacement parts. A double kick stand helps alot plus with a rear stand too your good to go.

    Use a double center kick stand or tie it up to something.
  12. I had a car-bike accident in Oct. on my GEBE-Robin 35. The bike landed on the engine and the right handlebar. The engine continued to run on it's side till I shut it off about a minute or two later. I was busy getting myself off the pavement and checking my old bod for damage. I sustained damage as did the front wheel and fork. The recoil starter cover had a little paint scratch, the end of the right hand grip was scuffed, both front and rear lights broke their mounts in the initial crash, and the little exhaust extention I'd added was pushed to the back about 1/4 inch. Otherwise, no problems. The car driver's insurance paid to replace the front wheel, fork, and the lights, eventually.

    Like we used to say in Chicago (many,many years ago)..."Lock it up; Nail it down; or, Take it with you"...and you should not have to worry about it. Or, you could slip a sawbuck to the big guy with the Louisville Slugger who calls himself 'The Bicycle Protector'...he will keep an eye on it for you so it stays upright.<g>
