Gear Lever Change

Hi guys bikes been running great But really am struggling with the gear change, my 05 daytona 955i has a gear lever connected directly to gear change shaft and I'm struggling to change gear when riding fast and keep missing gears. Seems to have a lot of up and down movement and if I don't fully drop lever in between gear changes it won't go in to next gear, I've adjusted lever and it's slightly better but finding it uncomfortable to change gear. Any idea peeps or would a set of rearsets off another triumph fit with gear lever on the actual rear set. Cheers in advance.

 

Yeh I got a pair of ankle boots just normal leather ones like work boots and change gear better in those for sure but in proper motorcycle boots it's crap. Damn gonna have to see whether it's worth keeping bike as I'll end up trashing gearbox. Bloody hell always something to mess things up
