Triumph 900 Sprint Carb Shims

You will probably find that you only need to fit a few new shims as you can swap them round to correct the clearances, last time I did shims I had to replace 2 out of the 8 ( yam xj650 ) to bring them all back in spec.

Google will probably find you the best place price wise for shims

You cant tell what clearances you have on a loose head, those readings will change one the head is fitted and torqued down.

Don't know about the super 111 valve clearances but as far as I'm aware all of the T300's use the same clearances
COLD
inlet 0.10 - 0.15mm
exhaust 0.15 - 0.20mm

Good luck

 

i know there are valve shims from hondas that fit, cant recall which bike fitment tho. try your local honda dealer or do a search on triumphrat.net.......forums........sport and touring......T3, sure i have seen it in there somewhere

 

I would avoid using the super 3 head. they have a bigger combustion chamber so will loose you power. the clearances are the same anyway.
bigger because they ran short stroke pistons. Triumph were worried the comp would be too high so made the combustion chamber bigger to bring the compression ratio down, but in actual fact they run fine with std head and give more power. My trident 900 gives 108bhp at the tyre with short stroke pistons. Shims are std 25mm as used by Yamaha and Honda and are available from places like wemoto or Wurth

 

You were lucky. I understand they are all gone now. Dave Lilley purchased the last 5. Has boosted the market for 2nd hand 750s just for the pistons.
rather than super 3 cams I would go t595, super 3 are just too radical.
