I've heard good things about Mez to, but the Testarossa kit is "more" than just a porting job.
As well as gas flowing and big valves, there's new guides and seats, MBP collet systems for the shims, modified inlet manifolds, new FIM ECU program and new cam bearing covers and oil lines to improve the oil feed to the heads.
MBP's bikes have been running rings around 748's and chasing down 916's in the races. This is one well put together "package" that makes the most of that lovely 2V grunt, that I for one miss on a 4V albeit 748.
Yes, it's not the cheapest work around, but along with a bore change this little lot has been pumping out serious BHP and torque for a whole race season in the US and Canada, with no work at all needed to the engine.
That can only mean solid realiability on the road/track day which is after all what most of us need day in day out.
One things for sure, BlooDuke will be getting a new lease of life akin to dropping a few tabs' in the tank, and Mort will have one special bike, which at the end of the day is what his goal is
