Welcome to the Group! If you don't have a repair manual, it's highly recommended Occasionally you can find tutorials on youtube that are helpful Sometimes the small seals in the piston of the master cylinder go bad.
The problem I found with my 550 & 650 were the seals in the slave cylinder were shot. When I removed the 3 bolts on the side of the case near the shifter, it looked like cottage cheese inside & nothing like fluid! You'll need seals #9 & 15 in this diagram- http://www.bikebandit.com/oem-parts/1983-honda-night-hawk-650-cb650sc/o/m151745#sch558418 There's also a kit available from E-bay with the seals $15.50 & free shipping- http://www.ebay.com/itm/Honda-CB-550-650-700-SC-1983-1986-Nighthawk-Clutch-Slave-Cylinder-Repair-Kit-NEW-/311447662191?fits=Make%3AHonda&hash=item4883ba2e6f&vxp=mtr -Bernie On 09/27/15, ADAMinIowa wrote: Following symptoms after starting fine in neutral: - clunks out / jerks forward when put into 1st (even with clutch handle engaged) - I can get it going by giving itgas when putting in gear (jerky/rough) - Clunks out coming up to stop - clutch handle has almost no tension - still feel the rpms change when shifting even with clutch handle fully engaged - really hard shifting between gears with pedal Basically feels like the clutch is always let out. Flush fluid? Anything else? First timer w this stuff, thanks!!!! -- You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
