I recently installed a viper crankcase and crank with srx cylinders and heads. I know the porting is different on the viper crankcase so should I upsize my jetting?

Oh yeah I already have the pickup for the mag machined to fit the srx stator
The 2000 + up SRXs share the same crankcases with the 2003 + up Vipers. I am running a Viper crank in my 2002 SRX. The 1998/99 SRXs use a different crankshaft, stator. flywheel, and cases then the later ones.

I made sure everything was spotless not even a piece of lint and the drip went away Thankfully! Im good to go I guess! John at Yamaha told me that the viper crankcase had diff porting? I figured that all the porting was in the cylinders! I dont know why he said that or is he right? Maybe he was thinking I was gonna use the viper cylinders
