Rough Running, Cutting Out

Hello, recently brought a triumph thunderbird 900 03. It’s ran fine for a few months if not a little rough once first started, but today it started running lumpy and seem to get really hot, it was then struggling to idle and cut out and wouldn’t restart. Left if for about 10 minutes it restarted ran fine for another mile or so managed to limp it home, relatively new to motorcycles so not quite sure where to start diagnosing this problem, any help appreciated.

thanks.

 

Thanks, will give that a go.

 

so been in the garage today, managed to rule out the air filter and the choke sticking. It’s now developed a bit of a misfire on cylinder one. Will get some fresh fuel tomorrow and some redex, will also check the spark plugs.

 

The fuel doesn’t seem to have fixed the issue, will try coils next. Where’s the best place to get parts from?. Thanks for the help.

 

Thanks for all the help guys, fired it up today ran fine for about 10 minutes then died and wouldn’t restart. So have ordered new coils fingers crossed that sorts it. It was also started making a tapping noise coming from the left hand exhaust.

starting to feeling like Iv made a mistake buying this bike haha.
