RedRicer Posted October 17, 2023 Share Posted October 17, 2023 2004 6th Gen Long story short: Bike stolen. sat for a year. replaced clutch slave gasket. flushed, replaced and bled DOT 4. Rides and operates fine until about 15mins of highway riding and then the clutch starts to slip. I drop a gear to accelerate and the engine revs with no power being put down. Is it time for a new clutch? and why does it just suddenly start happening after its all warm and toasty? i didnt want to pop it all open without consulting the oracle first. thanks in advance.

Member Contributer Captain 80s Posted October 17, 2023 Member Contributer Share Posted October 17, 2023 New clutch time. Because that's when your old clutch wants to start slipping. A different bike might do it sooner, later or all the time. All sounds pretty normal and expected to me though. If I got a recovered stolen bike back and the clutch was slipping after servicing the hydraulic system, I know what I'm doing next. Also be sure you didn't over fill your clutch master res, need to leave some air space in there. 1 Quote Link to comment Share on other sites More sharing options...
Member Contributer Terry Posted October 18, 2023 Member Contributer Share Posted October 18, 2023 One other possibility is that the clutch master has some residue blocking the return port; this can cause the clutch to slightly disengage as the line pressure is unable to release fully, taking some of the clamping pressure off the clutch plates. As it is less invasive I would start there. 1 Quote Link to comment Share on other sites More sharing options...
RedRicer Posted October 23, 2023 Author Share Posted October 23, 2023 thank you gentlemen. what would be the best way to check, or at least snake the return port? a needle, or pipe cleaner or something similar? Quote Link to comment Share on other sites More sharing options...
Member Contributer Thumbs Posted October 24, 2023 Member Contributer Share Posted October 24, 2023 I don’t think a pipe cleaner is a good idea with the fuzzy outer A piece of copper wire should be fine Quote Link to comment Share on other sites More sharing options...
