Question about 2007 Yamaha YZF-R1
Hi, if the 2007/2008 r1 spins fast but chgs and has to be coakst with the throttle to keep running and cuts out when the throttle is closed then it maybee due to the battery, i have fixed lots of them now afterm much fault finding by fitting a new genuine or yuasa battery. The problem is that all the power is being used to spin the engine and even once started there is not enough voltage to fire the spark and injectors properly and the charging system has not yet been able to pull the battery up. REPLACE THE BATTERY IT WILL SORT IT, PAUL (YAMAHA DEALER)

Run a little Seafoam maybe start out with1/4 can to two gallons gas..when you get your bike started get on the thing it will probably still have the problem until the seafoam carb/injector cleaner gets in there and does its thing...i had a very bad constant hesitation problem it took 10miles before i felt it spit it out....runs great now and i use it everymonth about 1/3 can to full tank.
