ok guys i been reading around on the forum for almost 8 months or so and i encountered my first problem that i cant fix. i was doing a 520 sprocket conversion and i was pulling the clutch slave cylinder off and sprocket cover off. well the previous owner (who did great taking care of the bike) just not the chain. well it pulled the pushrod out. i cleaned everything up and put it back together. well now the clutch will not disengage the clutch. i took the clutch cover off and everything looks great. i pulled the clutch its nearly brand new. i have had the slave cylinder off 10 times or trying to find out whats wrong. it pushes the piston out fine. well while i was there i took the slave cylinder apart and cleaned out the gunk. put it back together and the piston moves but its like it wont develope enough pressure. so i took the master cylinder apart. it was pretty dirty as well and it went togehter and i bled the whole system again. (went through about a pint of fluid with no bubbles) and i still have nothing. i have looked at exploded views of both parts and everything seems to be right. (i dont get any resistance at the master either so it wont put serious pressure out)
if yall can help that would be amazing. i have already done so many things to my bike all learning from the sight. i put in projector HID. i had greg set my forks up (super awesome guy too btw, and he does a great job! recommend him 100%) goin with a 1 down 2 up sprockets (havent got to try them yet) and i made my own exhaust that isnt to loud but doesnt quite have the sound im looking for. may go with some jardine high mounts.
but anyways this forum community is great and i wouldnt have learned half the things i have with out you guys
thank you again everyone

oh and everything worked perfectly before i took it apart too. i restore cars for a living so i regualarly take things apart and put back together.

 

I am in the middle of this same sprocket swap myself right now. Mine is apart and all the DOT-4 has drained out. Funny, my bike was pristine with the exception of the chain as well.

I am wondering if you have a bad seal somewhere. Has any fluid leaked once you reassembled?

I do not know if this matters, but was the bike level when you did the bleed? If not, you might have an air bubble in there. I do not think that would cause a complete failure though.

Did you use a Mityvac to bleed, and did you use teflon tape on the bleeder threads? It is the best way to bleed anything.

I will pay attention when I put mine back together and let you know if I discover anything. Please let us know how you make out as well. Thx. JB

 

Still sounds like air in the lines to me. If you have not tried a vacuum bleeder then I would do that next.

When you remove the slave cylinder (clutch actuation cylinder) the piston pops out a bit and sucks air in through the master cylinder. This does not happen every time, but it has happened to many many people before you. The trick is the tie the clutch lever to the bar before you pull the actuation cylinder off. This prevents the problem.

These things can be tricky to bleed. I have heard of people doing it with a syringe, and filling the lines from the actuation cylinder, rather then the master cylinder. Personally, I have only done it from the master cylinder.

 

Honda recommends tying the lever to the bar in the service manual. It didn't make sense to me, but since you mentioned it as well, I think I'll try it when I replace my chain. I also read something somewhere about wrapping a rubber band around the slave cylinder as it's pulled off, to prevent the piston from popping out.

 

well guys this was odd. you were right it was air in the line, however the location of the air was the weird part. the clutch line that comes down from the bars comes down and back up. my line goes uphill about 1" above where it comes down. well anyways it was holding air in the line at the top of that loop. i straitended the line out and bam air 2 bleeds in a row and she is fixed!... bad thing is.. i tore the clutch cover off and everything! soo hastefully pulling the side case off.. but i see i have a near brand new clutch! anything else i should check or upgrade while i have that off?

 

The clutch is a no problem unit on the VTR, so no real need to touch it. As far as mods go, the one component in that side of the case that is rubbish is the shift star. Factory Pro make a replacement that is 200% better than the OEM rubbish, but you need to pull some bits off to fit it.

Now may be the time for you if you want to improve the gear shift.

I put mine back together tonight - worked perfectly. I can think of 2 causes for your problem:

1. You still have air in the system. I used a Mityvac to bleed it, it just works well.

2. Is it possible that you forgot to put the rod back in?

Pls let us know - thx. JB
