I found a dealer in NJ that claims to have these factory GRP 75s. The guy I talked to said that the bore was the same but the stoke was lengthened. I know that this will definately effect the rev of the engine. A shorter stroke allows for a higher revs. Measuring the bore might do you know good. I haven't found any proof on the net that the factory even makes these. I have emailed both the UK distributor and the factory for info. I haven't recieved any yet.
