Best method for running in?

It appears my sprint likes oil, 650miles= at least 1.5 ltrs of oil, with no visible oil leaks. On searching tinternet this is usually the piston rings not sealing?, some folk believe this is due to the engine having an easy time during running in, and there opinion is basically warm it up then give it a good thrashing, as opposite as you could get from what the manufacturers say. mine will be going back to the dealers tommorow but if it does require rings fitting, then it will need to be run in again? your opinions please. 1050 sprint st 14500 miles, fooked.

could be the rings are 'gummed up' threw lack of regular oil changes and letting oil pizz up the bore. or if it has carbs it could have had burgerd emulsion tubes and 'washed' the bore with petrol which seriously reduces the life of the bore/rings. or valve stem seals. what ever it is 1.5ltr in 650 miles is not good. how long you had the sprint?

that amount of oil would have visible signs out the pipes.

If its just the rings being replaced I think the best way to run it in is hard use.The reason for the kid gloves method is because a new engine has all the bearings and other moving parts to run in which is best done sympathetically.
Im sure someone else will know different though.

Bibio, had it about 4 weeks,edit picked it up on 26th of march so not even 4 weeks yet, and yes there are signs out the back, lol, there is black **** all over the top of the tail unit + all over the pipes topbox rack etc, looks like carbon.


So if they just have to change the rings, give it some welly? obviously i will ask them what they think.

The first time i checked the oil, was not even on the dipstick, stick about 3/4ltr in, go 180 miles stick in 1/2 a liter and keep repeating, lucky i checked it the first time in time or it would have gone bang, no light showed on the dash.

Ollie's triple did this, we stopped en route to somewhere to top up his oil.....2 ltrs and a fair bit of frowning later we were good to go.

Think yorkie posted a link to a website with a guy's mechanics/science behind the 'harsh' running in theory.

I was once told, when engines are brand new they have machined sharp edges and corners that need to be smoothed and bedded in to suit it running. Take it easy for the first few hundred miles, then after a bit you can progressively ride it harder (when warm) to stop the clyinder glazing or something I forget.

No idea if the above's true (or accurately recollected), think it's just one of those debateable subjects - luckily I have no need to worry my little head about it as I'm a tight mother forker.

+1 I was always told to run my bikes in like this.

Is it gummed up rings or leaking valve seals which is causing the high oil consumption?

Few of the mag articles about Trumpets highlight some of them as thirsty oil drinkers, but I don't know if thats generally the case

That was with incorrectly fitted piston rings, as it turned out... did about 1500ml of oil in 1000 miles. The dealer was telling me how sprints tend to suffer with middle cylinder issues though, so I'd tell them about it at the earliest opportunity.

Another triple with oil usage problems

Ok, it doesn't affect every one but there is surely some problem. Maybe some rings were out of tolerance, but I believe Triumph still deny there is any problem. It wouldn't be quite so bad if you could just check an oil window every day but faffing around with a dipstick is going to mean a lot of owners won't bother and will only find out the levels low when it's too late.

Bugger for you BFM though . Hope your dealers better than Ollies original one.

I assume your going to Youles?

My mate has never had any problems with them.

For info, he ran his street in as per the book and it uses zero oil, Mine didn't use any during running in either but I'm not really used it in ernest properly yet so will have to see.

Does sound like some other problem though, I assume it's a used model, either the prev. owener didn't notice it (which would worry me what else they failed to o) or, you're unlucky and it has developed a problem since you bought it (ride it harder amybe, showing up the issue?)

Just ride it, no excesses though, so no huge speed and no low revs at big throttle. Don't hold it at a constant speed for any period of time; open and close throttle, this cycles the ring pressure and beds the ring face and cylinder walls properly.

Triumph recommend fully synthetic oil - don't use it in a new engine though it may not bed in right.
