    Hola Mofos

    After replace my clutch for the 3rd time.....There is still whistling noise during start up.
    Here is the story
    Order Barnett kits installed and it hard to start at first but finally it start but there is a slipping (whistling) noise when I start. I took the Barnett off and reinstall my old clutch and the issue going away.
    I then order the OEM kit and noticed the friction plate are different from Barnett and from my old kit :Frusty:
    I when ahead and install the kits per the diagram. I noticed the manual only called out friction plate A and B
    WT..............:Crazy:

    After reinstall the new OEM kit the noise still there. What the hell going on here....?
    Can one of you Guru shine some light for me? I am at lost at the moment.
    I have done this many time and have no issue until now. Thanks in advance .




    The Barnett kit came with 1 bigger in ID and 7 regular friction plates
    The OEM came with (1) number 7, (6) number 8 and (1) number 9.





    My old friction plate came with 2 (Big OD) friction plate

    I haven't listened to the clip Long (I'm meant to be working). Is the clutch pulled in when it whistles or is it out?

    I put an EBC kit in my 5G last year, no issues at all. The bigger ID disc goes in first and sits over/around the washer and judder spring (6 and 14). The judder spring is meant to be fitted with a specific alignment.

    Whistling at start up would likely be a dry bearing somewhere, I'd take a look around the end of the pushrod where it contacts the clutch lifter plate/bearing. If needed you can pull the pushrod right out from the slave cylinder side.

    It's only whistling during start up in Neutral so the clutch is close. I will try to start in gear with the clutch open to see if the issue exist.
    Yes I install the BIG ID friction plate in first as shown on the Diagram.

    I listened to the video. That sounds more like the starter clutch screeching to me. If it only happens on startup, seems less likely to be the clutch.

    Terry you are right. Further examination I have found the noise came from starter clutch and not disengage like it should.
    I compare to my buddy VFR after starting the engine I hit his starter button again and his is quite Vs. Mine is not. I will have to take a look at diagrams and try to pin point the rubish. Thanks for follow up on the issue. Greatly appreciated. Have a cold adult beverage on me mate.

    Boss, the midgets let me out for a little bit, then its back to the cave!

    In the video, it sounds like the starter is running on.

    You say the new OEM friction are "different". Are they thicker, or what?

    I'd be looking at the starter, not the clutch

    Boss read the first post. Took me 3 time with 3 different set of clutch. Yes the vfr is having new clutch for the 3rd time. She is reaching 100k miles in anytime now.

    I switched to a Barnett way back and it still seems pretty good. Did you torque everything to spec in order?

    +1 for looking at starter.

    I think I know the problem, Long. On the left handlebar, there is this lever that you are supposed to pull in when you get ready to shift.

    1. pull it in
    2. click the shifter into gear
    3. gradually release the lever while gradually applying throttle

    Problem solved.

    yeah, but you have to take the whole engine if you want it. I'll be moving soon so I'm trying to downsize.
