What does it take to make a drr50 run with a stock 70. We are running a 50 class for hs but may also run bump up a class and run in a jr 90 class. I have the basics but was wondering if or how much it will take. I know alot of people are building the production 50's this year but didn't know if anyone would let out any secrets.
We have a stage 6 cylinder with a 90 pipe and the recomended clutching, 21mm keihn carb from hetrick.
Also does anyone have a dyno run of this setup just so we can verify rpm range with our tack for the clutching.
thank you
