Hi I got my hands on a bws 50 by yamaha, came in as non runner, i put a new battery in, cleaned the carb thourougly, there is spark when operating the qickstart but nothing happens, there is gaz in the cyclinder when i take the plug out. compression is there, get's harder to kickstart after 5 or 6 kicks. When i turn the ignition on, the automatic start just click mildly and the oil check doesn't light up
any ideas?
thanks for your time

Welcome to the forum.
Clicking when trying to start a motor is often times a problem with a dirty battery cable, a failing battery or a bad ground.
Take a look at the battery cables first and clean them, if it does not work better put a charger on the battery or have it checked for a bad cell.
When you had the carb off did you look at the reed valves?

What year vertical or horizontal How old is the gas Are you using a new plug or the old one Did you clean out the exhaust What do you have for compression You do have the air box on right

ok so:) : the battery is brand new and fully charged, replaced the automatic choke with a new one as wires were fused. I didn't have a look at the reed valves, next job then... it is a 1998 motogp edition so vertical cylindre,the plug looks brand new and correct spacing. I haven't touched the exaust yet but will have to soon as i need to replace the back brake arm cable thing. Compression is ok, almost imposible to kikstart after 3 kicks,the air filter is a racing one one from polini, not the cleanest i would say but seems ok to me. I had a look this morning and it looks flooded, cleaned to plug and after 3 or 4 kicks, plug is saturated. REALLY APRECIATE YOUR REPLIES, THANK YOU

Get a brand new spark plug Get an om air box And run a compression test it feels good doesn't mean anything
