kindest Posted June 23, 2010 Share Posted June 23, 2010 just bought a bike for 500 bucks.. an 1980 XS400 Special II. Drove it home 10 miles even on freeway etc and it runs real good.. goes thru the gears no problem.. the only thing is that the clutch doesn't engage till the lever is 99% out.. is this normal or do I need new parts for the clutch.. I tried messing with the cable via the handlebars but it didn't help. I haven't tried messing with the clutch main adjustment nut thing yet. thanks Link to comment Share on other sites More sharing options...
HoughMade Posted June 23, 2010 Share Posted June 23, 2010 Loosen up the cable, then adjust the main clutch adjustment, then adjust the cable. Until you do that, we can't figure out if the problem goes deeper. My sense is that the adjustments will probably do it. Link to comment Share on other sites More sharing options...

I was scared it was definately the sign of something bad. Link to comment Share on other sites More sharing options...
kindest Posted June 23, 2010 Author Share Posted June 23, 2010 ugh I just tried to adjust the main nut and screw and the thing will not budge under any circumstances. I did "Here's what you do. Get a 6 or 12 point 12MM deep socket. Put it over the lock nut, hold the socket with a vise-grip. Insert a Phillips head screwdriver (through the 3/8 or 1/2" opening where the ratchet attaches) and holding the screw stationary, turn the socket counter clockwise to loosen the lock nut. Make necessary adjustments. To tighten the screw after adjustment, hold the screwdriver steady and turn the socket clockwise to tighten the nut." from this thread.. http://www.yamahaclub.com/forums//index.php?showtopic=21465&st=0&p=120461&hl=+clutch%20+screw&fromsearch=1&#entry120461 any tricks or tips to bust that nut loose?

HoughMade Posted June 24, 2010 Share Posted June 24, 2010 Were it me, I'd take sprocket cover off, take the whole clutch actuator off the sprocket cover from behind, then work on it on the bench. Having done that, my rule of thumb is that if it too tight, it needs heat. Not red hot, just enough flame to warm things up. I use MAPP, but propane would work. I would only do that if the part is removed, like I said. Mine was so tight it almost sounded like it was breaking when I finally got it free.

Mine was so tight it almost sounded like it was breaking when I finally got it free. dunno maybe its like mine ... i would turn mine 1/4th counter-clockwise and hit major resistance (cable will move when you try to loosen it), just got to go through it. It will make a snap sound like something broke inside, but thats just the locknut snapping loose. if yours looks like isnt rusted, just apply more force than you think. I was messing with it 5 times last month and had no problems. PS you dont need the vise-grip to get it off with the socket... use the socket wrench, it'll give you a better grip/force... u only need the visegrip instructoins when you made the screw adjustment aftwerwards... You need to hold the screw inside stationary (with a screwdriver going through the socket) while you turn the locknut clockwise with the visegrip. PS having one of these box spanners is nice to have on hand. u can use the 12mm socket side on one of the spanners, and then use a 17mm wrench on the '13mm' side (13mm+extra steel) and tighten it without using a visegrip. (visegrip will work as good, but i hate it when it slips or scratches up my shiny socket hehe). Link to comment Share on other sites More sharing options...

I will try just the socket. the kicker is I bought the exact same motorcycle today for 100 bucks (parts bike) w/ siezed motor and pretty rusty and that damn screw turns no problem. ARGH! lol ok update. I broke it free. I guess I was being a lady... I really put some torque on it and it did make a snap crackle pop sound but its all adjusted now and the clutch is engaging much earlier in the release. thanks everyone.
