last year the bike,a 2002 model ,slipped on gravel on a road in Scotland..the engine kept going till switched off and it lost some of the casing below the legshields on the right side.I ended up in hospital for a day! lol
I then had to drive it home, but after 340 miles, in some atrocious weather ,it made a funny noise then the engine stopped.It had been running fine before then and I had checked and and topped up the engine oil before i started. As i awaited a repair man a large pool of oil spread out from under the breather onto the road.
Any way, home and even in front garden oil was present..but i havent been able to work on bike due to a huge number of things including recovering and really awful weather all last summer .
When you insert the key and pressed the starter button there was defeaning silence(as it was when it first broke down)
So the help..where do i start in finding the cause...I suspect the engine has gone......but how can i test? On a motorbike i can check for seizing by turning the wheel..not so easy when scooter has variable gears?If the engine as gone its off for repairs or spares.........but it might be something else.
I have a limited space in front garden to strip it down.....i wish it was a garage
All the lights and indicators seem to work.....but i get no thud off the starter......would for example the opening of the casing on the underside due to the accident allow water ingression and so short something?Or the water to get into an intake and so into the engine?
i would appreciate your views.....at the age of the machine, in good condition, they are worth about 1500 UK pounds...at the moment about £250 as spares with no engine going!
thanks folks

Well, Normally there is a Engine Cut-off Device So when the bike drops it Cut's the engine all most Instantly, This Prevents Damage to the Cylinder, Now as many times as i went down atleast it did cut-off on drops, I gave a old girl friend my old China scooter and she crashed it into a fence and dropped it. she was only going 15 miles, but the engine did not start back up again, I can only assume that the Rings Broke on the Piston. Cuz the kick start moved real freely when kicked. which means lost of compression.

but come to think of it i went down Harder, Hardest and once at 40 Mph , But it still Started right back up. with no problems Ahead.

Good Luck,

Elliott,

You could pull the plug, and with a finger (thumb) on top of the opening, use a 24mm socket and ratchet/breaker to turn the crank via the variator nut, and feel for the compression.

If you can't feel anything, it's likely there's internal damage.

Good Luck!

My best advice it to find a local riding buddy who knows much more than you know........and first see what parts are broken or missing.....! If the bottom of the engine case if broken off - It seems like an engine removal is in order....!!!!! Good luck! :thumbup: :thumbup:

The easiest thing to check is the kick stand switch which most likely got damaged in the crash.
After that it is an engine tear down.
