hi, i'm new here and i need infos. I'm getting a little confused cause i got some clutch slippage on my 05 rstd and i saw a lot of treads on the subject but i don't see the main difference between a barnett, pcw or skydoc solution. i need to do the job fast cause here in montreal, riding season is short. my rstd got 125000 km on it and just slipping in 4th or 5th gears and i feel a lack of power while cruising at +/- 65 mi/h on highway. since it just slipping a bit, i think the previous owner already change the disc before but who knows. can i just change the spring and if it dont work change the discs later? By the way, forgive my english but i'm mostly french speaking so i try my best
