before you all start telling me i am wasting my money i want to get a few things out on the table...... 1. yes the motor is stock 2. yes i am ok spending my money on the VP U4.2, its for a track day! 3. i am fully aware that i MAY NOT notice a big performance increase 4. I love each and every one of you for commenting on my adventure so enough of that! i am wanting to run some VP U4.2 through the ol DRz. I have a full system yosh rs3 3x3 mod re jetted with stock carb. VP says that i can possibly run her with stock jetting i am currently running the Eddie recommended jetting for the RS3 and 3x3 at sea level ( if i remember correctly its slightly rich) am i good to just pour the VP in and go? or am i going to need to rejet? have any of you ran U4.2 through your DRz's? if so, what did you think? let me know! i plan on doing a ride report with U4.2 and pump gas on here in the next couple weeks when i go to the track!
