Seems we have a lot of recurring questions on clutch slipping.
Check it out, hope I did not miss anything. This should help the new folks.

 blush I might have a stupid question... -but my momma says stupid is who stupid does- so here it goes.

How does it feel when the clutch is slipping?
I am having the hardest time changing gears, like getting neutral is nowhere there, and first also very hard like kicking it down and I feel like I am destroying the thing.
Is this a sign of the clutch been slippery? I was thinking maybe some of the joins and axels need some lube or so...
I did anyways buy a shifting Detent kit from RPM and will give it a go to install it, but I know I have to remove the clutch anyway, so if this is a clutch issue I could already kill two birds with one shot.

How can I differentiate if the shifting issue is not the clutch? I am starting a thread right now but thought to give it a try here just in case. not trying to hijack this thread at all...
Just thought it should be nice to have a clear image for us new to this what to acknowledge as clutch slipping problems.
Thank you very much.

A slipping clutch is easy to test. Ride where you can accelerate hard safely. Perform WOT (Wide Open Throttle) pulls once you are in 3rd gear. A slipping clutch will allow the engine to spin up to higher revs quickly with no benefit of acceleration. Hard shifting may be a leaking clutch slave or air in the clutch hydraulics. This causes the clutch push rod to push less. This means the clutch plates are still dragging a bit so the gears still have load on them when you are shifting.

Test for clutch slip, then report back...

This is timely for me because I think my clutch is slipping at WOT and high RPMs. For now I'm just avoiding that bit of fun because 1) I want to get back to the airplane and 2) no problem keeping up with the V30 Magna.
