Smokin' 1972 Triumph Trident T150V 'Purple Haze'

This is for Triplers to see Purple Haze in action. My first attempt at a video and I managed to call the oil pressure gauge a 'rev counter' - senior moment I guess. Narration is harder than it looks! Despite good bores, pistons and new rings this T150V has a mystery oil burning problem that is at it's worst when standing at idle and on acceleration after long overruns. What do you think?

The problem was the piston rings. I had fitted non-standard piston rings which had exerted too much pressure on the bores wearing them rapidly. Re-honing the bores and fitting the standard rings has cured the problem and Purple Haze is now a non smoker!

Failed crankshaft seals would only cause a 2 stroke to smoke as the oil gets sucked into the crankcase from primary drive and then pushed into the heads via the transfer ports. Tridents are of course, four strokes. Mine used to get about 30 to 35 mpg ( Imperial gallons ) and about 1 litre of oil every 150 miles as did my mates T160, LOL!

Don't believe it; mine was a smoker too. I used to change the rings and sometimes guides. it would be great for a while and then it smoked again usually after a good thrash. A friend of mine had a T160 and guess what, it smoked! Horrible on fuel too- never seemed to matter though. I still love em and would love to get another one
