Hi Rob, if you go to this website and select your bike, you'll find all the part numbers you'll ever need : http://www.worldoftriumph.com/triumph-motorcycle-parts.html?SID=e6lr1a46b6hmnlpnq5hpbmu0f1
Happy to help mate https://www.dropbox.com/s/ia2hex5rw70pip4/Triumph T300 Service Manual.pdf?dl=0 below is the parts list from Fowlers, they use Triumph part numbers whereas WOT use their own numbers until you checkout. Fowlers are cheaper too in most cases. https://www.fowlersparts.co.uk/browser/manufacturer/triumph/bike/tiger-885-carbs-71698
Thanks guys. Got a good bit of bedtime reading there. Started my list of jobs. It's gonna be a long one
Got a blog up but very little done to the bike as yet. Have ordered up a couple of bit's including a spark plug spanner. That's a silly place to put a spark plug http://www.robsbots.me.uk/ in case anyone fancy's a look.
