Not really once you learn them.There are a few reasons,mileage(15 mpg) and bog. I like to ride my max the same way I rode my mototcross bikes.I shift a lot.Rolling the throttle doesn't fit into that scheme of things.The bog at the drag strip blows big time!
I also want to continue working on racking my R1 carbs something like the stock carbs,maybe even open vboost like mine now.
Maybe because I am running vboost eliminator tubes?
It definately started,idled and reved fine in nuetral.Didn't run right on the road,felt like only 3 cylinders.Only my number 1 plug was black too not 1&2?It really kinda pissed me off that I had to pull the carbs again and unrack them just to put the nozzle screw back in.But then again I was glad to have spotted the problem.
