CLUTCH SLIP HELP

[finless]

My clutch vacuum assist was not working. For how long I do not know. It did not burn out my clutch.
When I flushed my fluid I pulled the check valve and cleared it of oil. What happens (thanks to another Spyder owner telling me this) is oil in the air box (which can happen) gets into this valve and fouls it. I cleaned mine up and now it is working correctly.

I am sorry your selling your Spyder over this. A proper Mech should have followed the test procedures in the service manual and found this problem EASILY. It is WELL outlined in the service manual on both test, check, and troubleshooting.

There is a solenoid switch mounted to the front of the motor, with a air hose that attaches to the side of the clutch.

The solenoid malfunctioned and the switch stuck in a position which caused the clutch to burnout. It happens fast when this happens. So much so that the two clutch packs the dealer installed before they repaired the solenoid switch showed signs of damage and wear. Replacing the clutch pack does not remedy the problem. The clutch actually slips worse with a new clutch pack installed.

That's the clutch solenoid valve (CSV) and check valve that I mentioned earlier. If the CSV sticks in the wrong position, it is as though you are lightly pulling on the clutch lever all the time. As Finless notes below, your dealer took a shortcut in his troubleshooting and should have found this early on, saving you much of the aggravation.

If your CSV stuck in the other position, the clutch would work just fine. But you'd develop some strong hand muscles from pulling on the non-assisted clutch lever all the time. Good to know that you solved your problem by cleaning it of oil. The vacuum line actually runs to the throttle body, not the air intake, and it is a strict one-way system. It either pulls a vacuum against the diaphragm via the vacuum present in the throttle body or it vents to the atmosphere and the diaphragm relaxes. The check valve prevents the atmospheric vent from getting into the throttle body. I would be concerned that you've got a tiny oil leak thru the diaphragm that is getting sucked into the valve. The manual notes that a damaged diaphragm would allow enough oil to be drawn in that you will see blue smoke out the exhaust. I could guess that a tiny leak could end up gumming up your CSV valve but not be significant enough to see any visual evidence out the exhaust. For the oil to come the other direction, it would almost have to be that you've got enough oil fumes in the throttle body to condense and run down thru the hose, thru the check valve and end up in the CSV solenoid. There's no vacuum pulling that direction so liquid running downhill is all I can think of. Doesn't seem too likely to me but what do I know? I'd at least think about the diaphragm.

I want to thank route 1 motor sport and I of you who have posted about the clutch problem got mine fixed with all the parts that were suggested here if anyone wants the list and part diagram of all the parts used to fix the problem of dark and missing clutch fluid PM me and I will email the paper work from my repair.

Well to be 100% correct I was told it can foul from oil. I just cleaned it out and it worked. So oil or not I do not know. I did not see any in the hose when I took it out. So based on what your saying now, it probably wasnt oil just dirt or something.

it was a folly of errors

When the clutch was opened up after making the initial diagnosis that clutch slip in higher gears is from a worn clutch. To be honest I would have looked in the same place.

When replacing the clutch frictions plates, all worn or bent parts, etc didn't work they opened the clutch again and saw signs of premature wearing, they replaced all the other parts, diaphragm, springs, o rings, etc. Guess what it, it still didn't work.Guess what else BRP had sent them the wrong o rings which they installed. More of a mess.

They took the clutch out of a showroom model and put it in my bike. Still didn't work.

The checked the air box and it was dry.

They ordered the solenoid and the clutch master cylinder.

But the solenoid in first and bam!!! fixed.

This trial and error took six weeks.

I have mixed feeling, because the dealer has always done amazing service. And I mean amazing!

The upside is the bike runs absolutely amazing. Better than the day I bought it. I would go as far as saying the shift points are better. The clutch lever is very stiff.

Whatever works -- that's what counts. I'll remember this if I ever have a problem and try cleaning it before just automatically replacing it.

In need of this info please having clutch issues with my 2018 rt base..

Hello if you could please forward me the repairs and price point you made to your Spyderpops it would greatly appreciated..thanks in advance. [email protected]

ldpost: . You might not get a great response from jtoro or too many of the other 'earlier posters' in this thread Mrlsession, cos apart from Billybovine & a few notable other 'still active' posters, the others may not be around to answer and are certainly quite so active here anymore either..... . Probably not all that surprising, since the last post before yours above was put up in September 2014! :shocked: . So most of the responses & info here will be getting up towards 7 years old & may not be of too much help.

It might be better to start a new thread of your own, with a Title that briefly states your question &/or what you want from the thread. :thumbup:

Good Luck! :cheers:
