Hi needing some advice for the valve timing on a Lexmoto xtrs 125, I bought the bike in bits and have nearly got it all together but the position of the cam the cam sprockets and valve timing are really perplexing me. I bought the Haynes manual for Chinese motorcycles but it doesn't cover the engine I have. Does anyone know where I can get a manual for this bike or can anyone talk me through setting the valve timing on it.

Regards
Lomi
