Finally got them fitted .and working .
Id like to say I knew nothing of bike carbs how to fit them or anything.
I had some issues with the inlet manifold leaking air,but a new thicker gasket and some sealer sorted that one out.
I got it running on the standard jets but those weren't big enough ,so fitted larger ones on advice from a forum member.
Been for a quick spin earlier,it runs ok but obviously needs setting up which will be done asap.
It does make some nice bangs and pops with a rorty induction noise.
A huge thanks goes out to Dan e for me pestering him with messages as he used to have fireblade carbs so was a man in the know,and to mark b and terry aka tazzmann for me pestering them with calls and texts on weekends when I was stuck and at aloss.
Another top reason for joining the club and the s yorks mob is one of the best.
