I know the Razz is not the ideal scoot to be putting performance modifications on for transmission limiting reasons, but I got one in perfect condition with only 2,000 miles for extremely cheap so it is the platform I will be using.
My question is, can I use a yamaha jog or zuma big bore kit on it? I located some BBK's for the razz specifically on ebay but do not know how legit they are. I was thinking of going with a 70cc zuma/jog big bore and running a zuma/jog exhaust. I have already switched to cone air filter and jetted accordingly, and have bigger jets I can go to after making the swap. I'm not to thrilled on the idea of doing a motor swap even though I know that is a very popular route. Thanks in advance!
