Who knows a good bike tuner

[Motoracer]

I have bought a ZXR 400 to race in F3. I have done quite a few things to it. All I need to do now is get the carbs rejeted to suit the race pipe and airbox. I took it to a workshop in Mt Wellington but they gave wrong advises + completly stuffed up the top end. At the end I was stupid enough to give the money for labour because they didn't do anything I wanted and Made the bike go worst.

I don't really have the time or money to muck around with people who don't know what they are doing. Does any one out there have any contacts of good race tuners with good honest rates?

The guy You need to get hold of is Brett Roberts.
I don't have his contact details but he is Your man.
I'm not sure though if he is doing bikes at the moment but I know he's doing trackers. it all depends how busy he is whether he can help You.

Well I have a zxr400 and a moto if it aint broke dont fix it but I have increasing confidence with spectrum they have fixed a few things at resonable cost but I have heard that the Red Baron have a wizz kid but at a price.
So try brent Martin at spectrum first at least youll get good advice.
