Welcome to the trials and tribulations of Angry Scottish Biker, where we poke and prod around motorbikes, motorcycles, engines, tools and more. Listen to the general chitchat and ramblings of a miserable tight fisted Scottish bloke as he plods along in life making, creating and breaking.
My aim is to give people the courage to dig in a little deeper to their bikes, help them look after and maintain them to the best of their abilities.

Might be a stupid question but I’m changing the piston on my lads 50cc 4stoke bike and that’s a pushrod with 2valves do I after time it up when putting back together is does have timing marks on the flywheel but can’t see any marks on the casing but does have inspection hole at top of casing ? Thanks for any help Also changing gaskets on the cases do I torque them or just hand tight with new gaskets

What bike is that from? Some sort of honda im guessing? It looks luke a cg engine but it has dual exaust prots so cant be

[@angryscottishbiker5097]

No this is from Lexmoto Vixen, other wise know as Haotian HT125-8 and the Huoniao HN125-8. The engine is a CG125 clone, with some minor difference.

OHV is the most simplest engine
