Cheers guys!
I'm pretty sure it's not got a Dynojet kit.
I'm not sure what to do with carbs, so not confident with doing much with them for fear of bolxing them up!
I was planning on trying the rebreather mod but ran out of time - will try that, as well as putting the old exhaust back. Hopefully that will sort it!
Otherwise, it looks like I'll be getting famiiar with carburettors pretty quick, as being a poor student, I can'fford to pay garage rates! :0/

Thanks for the replies guys - fingers crossed!
