Beta Rev 3 engine smoke issue

[Dualta]

Hi everyone,

 

I was riding trails a while back when smoke started rising from the front of the engine near the forks. I’m not mechanically skilled, but a guy who was there reckoned I needed coolant. When I topped it up with coolant, hardly any went in, so I reckon that wasn’t it. Then it wouldn’t start. I cleaned the plug, but no luck. The manual asked for a NGK BR7ES plug, but when I removed the old plug, it’s a BP5ES. Plug discrepancy apart, does anyone have any idea what the smoke might have been, sand if it might be related to the engine not starting now?

 

Thanks in advance

Was it smoke (ie from exhaust) or steam from engine / radiator ?

Does the fan run ?

Did you squeeze hoses to check for air locks ?

Are you getting a spark ?

Is the plug wet or dry ?

It’s was definitely smoke rising from the front of the engine, from around the fan area. It want steam. That was the first thing I thought it was, but it was definitely smoke. 
 

I don’t know if the fan’s running because the bike won’t start. When it smoked on the trail, I walked it back to the car, which was close enough. I haven’t run the engine since. 
 

I haven’t squeezed the hoses. I’ve no idea how to do that, but I’ll find out and give it a go. 
 

I didn’t check if I was getting a spark. I didn’t know I could do that. I’ll check it in the morning. 
 

The plug was wet. I dried it off and took a wire brush to it to clean the spark end. No joy. 
 

Thanks for the help ?
