Over the last few days i've had to persevere with the bike to get it to warm up, mainly at the initial start up.
It's very throaty after hitting the button and i have to coax it in to life with the tiniest amount of throttle.
Once it's cleared it's throat i let it tick over for a couple of minutes then i'll warm it up by riding, but even that takes another 5 minutes.
The thing that's confusing me is that it's been fine all over winter with the really cold weather, but today for instance was way warmer than we've been used to and it's been starting like a pig.
The battery's okay, no issues there, and once it's properly warmed up it behaves absolutely fine.
Got a newish K&N fitted, and the bike's used 5 to 7 days a week so it's not sitting about.
For the record i initially started the bike today with a Moto GP end can on, but then put my old Quill race can back on and went for a spin and everything felt good.
Any thoughts please ?

Re: Engine Rough at Start Up
Update - funny thing....after doing a valve adjustment on my ST1100....found 2 valves were on the tight side...at the limit but not below the limit....guess what ? Two shims later they are all back in exact specs now and NO more rough start-ups. Only did it on very cold days and for very short time. Passing this on as a tip to check your valve clearances if you are having these symptoms.
