Hi!
One week ago I changed my 400 for the new 350 EFI. No comparison between the two in weight feeling. Still breaking in the motor. Suspension is ready for the first tightening at the back and adjustment of sag, at 4 hrs. The EFI system works great and on Saturday I will receive the first updated map from the factory. No issues with the initial map but probably the factory has got an even better setting. The almost non-existent engine braking (especially with 3rd and higher) is a thing I really like and I think it contributes to the very light feeling of the bike. We could call it a three stroke...
I will write more when I have some more hours on the bike.
