So you changed the chain and both front and rear sprockets using parts for an FZR1000 ~ what year ? Were these steel or aluminum ?believe or not i'm running +1/-3!!!!
i had a new 532 chain in my shed, so i went to the bike shop and bought 17tooth and 43tooth for an fzr1000 ( a bike i also own), as the front spline is the same and the rear p.c.d. matchs.
The bike still pulls from the line without need to slip the clutch. It accelerates a touch slower in forst. It now is really sedate on A-roads and motorways- thought the speedo is under-reading by 5% according to my tomtom.
I'm very pleased with it, can't wait to get into Europe.
