I have two issues on my relatively new 2008 C50 that I would appreciate comments on.... 1. Engine ´pinks´ under load at pull away especialy when you open up the throttle in a reasonably low gear. 2. Once the reserve fuel indicator is flashing, it seems as though the engine is sometimes starved of fuel when you open her up. My previous M50 had a similar problem but when the fuel low light was flashing, this bike actually stalled when you came to a downhill standstill....
