So i took the touratech handguards off and installed the genuine bar end weights back on, the black heavy ones.
seems quite acceptable now.
i was planning to for the brass in-bar weights, but i saw the inner daimeter is very narrow after the first part where the heavy black weights screw in.
first +- 3cm is threaded for the weighst and if i should make some brass in-bar weights, they will be so small in diameter, that they won't have any effect anymore... don't know if i have the original handlebar.
still if those black weights screw in ,it must be the std one then...
any suggestions?

playing with the fuel mod dodn't change anything.
checked timing of the cam chain, all is good.
