Hi JIm,
If you don't want to start tweaking yet, the mechanic should know what you are talking about and also, it should show on the dyno where she's lean.
For us to help you though, why not scan your dyno results so we can look at the results printout to determine where she is lean and hopefully what needs to be done. Also I'll be able to put your numbers into our dyno table
this onewhich will also help others like yourself see what different setups and settings members they have and their corresponding numbers are.

BTW, if you don't want to send your results, can you do me a favour and just tell me what main jets the mechs put in.
You see whilst I'm thinking they will be about 145's, I would like that varified by your dyno cos I had a similar setup prior to putting SS pipes on but now I'm considering exchanging them back for the tors again.

Staffo
