Reprofiling was not a great success
Butch in CA , an associate of Ack , did mine and Richards
there is very little material to work with , and was told afterward the tire grows a lot and doesn't reach its true shape till 250 or so
so a low speed cut will not necessarily run true at speed
Ours seemed to run fine
did several runs testing mine,
on a calm day Jims busa ran 181 and felt great
on the fairinged 750 it was less successful, only did 2 runs at WOS
one with big tail that was badly effected by 6mph side wind , and one with std tail that was even more effected by a 14mph side wind,
shoudn't have run at all but it looked like the quickest way back to the pits and i did want some info
In Australia, try Stuckeys tires for shaving
I will be putting in an application for a DLRA rule change to allow shaved road tires
Untill we can get a dedicated motorcycle 300+mph tire everything else is just a compromise
and the best results i have seen in the last few years were Rich assens shaved road tires doing multiple 250-260mph runs without issue untill they were worn out
