Having now just completed my first 101 miles, on my Bullet Efi DL. I am becoming more aware of how tedious this running in can be! The first 300 miles, no more the 1/2 throttle opening, and no more than 40 mph,( I'm sure my mileometer is running in reverse). Then a further 300 miles, at a little faster speed, at 3/4 throttle opening, and then on top of that 400 more miles, still with care.
Constantly watching the speedo, listening to the engine sounds for noises which you imagine shouldn't be heared. Also being conscious of not running too slow in too high a gear-which I understand could also be harmfull to a new engine. On top of this of course is the normal riding situations, with the added realisation that you are probably holding up the traffic.
Ah well, it will be worth it in the end.
