Heavy smoke

[silva]

Hi good day mates,
Rd125lc - just went for a spin and did a bit heavy this time, speed 110km/h. Came back and parked the bike while the engine running, heavy smoke and quite alot (unfamiliar). Is it normal? This is the 1st time riding it hard after the full restoration. Engine oil seems to be fine. Radiator in coolant also good. Temperature normal, not hitting the red line. Any thoughts or ideas. Thanks in advance.

Check and re adjust oil pump if needed. Also maybe a hard run has started to burn off old oil/goo in your pipe? Or dislodged some old carbon and partially blocking your exhaust 🤷‍♂️ What’s the end of the silencer like? Any oil running down the underside? And your gearbox level is the same as before the ride?

Hi beardy, checked the oil pump. No leakage from silencer, under the exhaust. Maybe burned out the carbon / silencer fibre, as u said. Started today and its back to normal, not much of smoke. Engine oil level is good and same level.

Hi there has it been while since it has been run as the crank shaft oil seal can start to break down and drag gearbox/ engine into the cylinder and burn it

Hi mate, so far the engine oil is not decreasing, checking on the level through the glass. The smoke had eventually gone, now back to normal, guess burned some thing inside the exhaust the other day 😅

probably just burning oil that was applied during the restoration build
