Hi Jordan,

123 monty has a perculiar 'selection' shaft which can cause issues, (end away from gear shift  lever) = on mine it has been repaired.

Maybe's worth an casing strip to investigate.

Parts for this model are not the easiest to find.............mines now down due to finding cracked flywheel, and none of he usual parts folk are able to help.

 

all the best

Andy, 

Thanks andy for the reply done some more looking and found that the gears for the kickstarter mechanism are worn aswell any idea are these easily sourced cheers

If you use good ol e bay, try cyclesavant who is a mine of info on Vintage montesa's (although is based in the states; ) 

Seems like a really nice guy, who has answered various questions I've asked him.

Just had a look and he is listing a cota 123 kick start drive gear items. as well as transmission items

Hope that helps

It looks like it's a late model, (badge'd Montesa/Honda),  MH123 so would hazard a guess at  mid 80's

Main difference over the earlier 123 cota is full sized wheels, exhaust system

Another source worth trying for pars etc, In Motion and www.Vallmoto.com in spain.

All the best
