VT125 C6 Shadow - Loss of engine power at 60mph

Any help would be useful. Accelerating onto dual carriageway and had a sudden loss of forward speed, engine will start but will not tickover unless throttle is held wide open, will not rev up.

Hi KCMC,
Year is 2006. Current mileage is 36500. Last serviced 4 months ago, approx 2800 miles ago. Bike is standard, no aftermarket mods. No other work has been carried out, no unusual noises or noticable changes in performance before losing power.

Fuel System

Would probably be the first point to check; is it flowing freely & contaminant free (no rust or owt in it). If it's got a filter change it. Drain the float bowl & check if there's water present (there shouldn't be by the way!)

From there it gets a little more complicated and diagnosis/solutions will definately need more info as kcmc says

Honda VT 125 Shadow C6 2006

Hi again

Check the carbs are seated in their rubber manifolds,you could have over revved the engine causing a back fire which has popped a carb off the rubbers?,could also have bent a valve?will need to do a compression test on both cylinders to check this,if it isn't a fueling problem as Amateurcynic has mentioned?Good Luck
