Thanks . I will be as carefull as I can, a dremel and flat file will have to take care of the rest.

I am still just thinking outloud but I believe your taper bored +2 will be a far better than a taperbore 38 with only  +1mm. 
I think that carbs work very well STOCK, but if you must customize the carb bore, it is best done to ACHIEVE A RESULT.

A 1mm overbore like I am planning is almost a waste of time perhaps. My butt dyno will feel nothing maybe. And in the same time, I can maybe destroy some of the great stock effieciency felt near the low end

Then again, its just a 34mm carb with smoking low end for this bike. Needed upgrade I state firmly. I feel that I will get to this in the next few weeks then I will wait to borrow an EGT, RAD guage or monitor the air/fuel mixture. Atleast for the first couple hours to confirm I wont melt the top end.
