Hello , i have a F 800 GS 2011 and i think i have an issue. I accelerate lets say being in 3rd gear (60 mph) , from 3 000 rpm from 5 000 and dont feel like the rear tires are getting the power till 3 or 4 seconds later, like if the transmission or the chain are slipping. I dont know if this is normal because im forcing the bike for being in the wrong year or if could be the chain or transmission. Please help.
