NC35/RVF400: Clutch is not fully disengaging
Posted: Mon Dec 30, 2019 1:03 am
I've recently purchased a RVF400 and on the second day of ownership I realised that the bike is slowly pulling forward while in gear with the clutch lever pulled in (as if the clutch is not fully disengaging) and currently trying to figure out what the cause is. I've ridden the bike for a few hours now and have not noticed any clutch slippage while going through the rev range.
I have tried the following:
- Adjustments made to both the lever and clutch arm/rod on the left hand side where the clutch cable attaches to and no matter what adjustments I make, it still pulls forward slowly.
- Changed the oil (10W40 semi-synthetic) and allowed the bike to warm up to operating temperatures
- Purchased an OEM clutch cable (22870-MR8-900) and compared the cable length to the current one on the bike and they were exactly the same length so I didnt bother swapping them over.
I am now looking at inspecting inside the clutch basket to see if there are any grooves that could be causing the clutch discs/plates to not smoothly slide and retract that may need to be filed down. Would there be anything else I should inspect closely?
I've purchased new clutch discs, steel plates, clutch nut, and clutch release bearing to change out as I may as well since it's being disassembled. Is it worth replacing the clutch springs?
Just wanting to reach out and get some more ideas/recommendations on things to check that could potentially be causing this issue.
Thanks.
