Puff of smoke
 

Hi not sure if this is a problem i have a blobeye running 340bhp 340ft/lb torque my mate was behind me yesterday and when i floored it he said a puff of smoke came out my exhaust is this normal thanks

Depends what colour smoke it was.

WhitE but he said it only did once when i first floored it

Mine does this sometimes if very warm, Just kepe an eye on it and oil use.

Was the engine warm, i.e. was it up to temperature?

I had just checked the oil and water its due an oil change in 500 miles hasnt lost any

Yes warmed up had driving 20 miles before i floored it
