hi guys i'm looking for some advice, the new laws say that on your A2 license you can ride anything up to 46.6 bhp restricted from no more than double its original power output so i was wondering if i had say a k1-k4 gsxr 600 and put an s'rad 600 engine (92 bhp) in it and change the engine numbers on the logbook would it be a2 legal as it puts out less than 93.2bhp? and how hard would the swap be and what else would need changing? cheers for any help.
