Hmmmm - tried to find a 'reputable' tuning centre I'd heard of in Manchester - no result !!! Sorry about that.....
So I tried looking in the Dynojet website
http://www.dynojet.co.uk and there is somewhere listed for both Stockport and Barnsley but I aint hear dof either of them - but the latter does have a dynojet 200 machine....
Might be worth giving them a buzz.
Does the 1995 model 900ss have carbs? I thought the injected models started from 97 but I been wrong plenty b4
Good luck - Frank
