So ive been looking for a new motor for my 08 agility 50
ive seen long case engines and short case motors whats the difference
Whats the best websites for qmb139 50 cc engines
-
you want the long shaft. the short shaft is for scoots with smaller belts and tires.

+1 longcase has 12" wheels, shortcase has 10" wheels. Ive never seen a 10" wheeled agility but they must exist ???

Sat on a 10 inch agility in the shop. But a averaged guy can only drive straight roads since it's unable to steer on that tiny little thing. ;D

Here's a pic of the motor is this a long shaft or short

Yep, they do... I own one, but compared to my 12" it feels a bit smallish and unstable.
It also looks funny when parked next to a 12" version, the top half is exactly the same as the 12", the bottom half is different, with small wheels, shorter engine case, shorter wheelbase, the front fork is thinner and less wide, and overall height is 5cm less...
Anyway, on topic : I wouldn't buy a 139QMB engine for a Kymco..
With those generic Chinese engines you never know whether it's just as good as a Kymco one, or whether it's made on a Monday morning by the cheapest manufacturer of the planet....
I hear a lot of disturbing things about this generic Chinese stuff... I would rather fix whatever is wrong with my machine, even if it means a complete rebuild - heck, It's probably even safer to buy a second hand Kymco engine instead of a shiny new 139QMB...
