Just went for a ride in the morning to test the bike and everything is fine.
I have done a complete revision of the bike and it's seems to be a real low mileage bike, i always doubted.
Fitted new air filter, carb cleaning, front pads, brake fluid, refurbished forks, and oil pump adjust.
The bike starts nicely and performs great. The OEM air filter seems to be more restrictive then the previous and i can notice less air flow and less noise aswell.
With the carb cleaning i now have better performance in middle revs, now revs up more steadily.
The only issue i have is that the lower cylinder burns more oil the the lower one. I'll checked the oil lines to see if it was clogged but it's fine also the pump is fine.
Maybe it's the carb air screw?
I have to check also the vacuum in the carbs, what vac gun do you use?
Cheers,
