First off, thank you for the new join!!!
I just purchased my first Busa from a friend of mine a couple weeks ago. He was the second owner and maintained well for two years. Nonissues.
Need to get some input if I could. I have a 2009 Hayabusa with 12,000 miles on it. I bought it from the prior owner and I’ve only put about 200 miles on the bike in a couple weeks No issues whatsoever.
Yesterday I wanted to reposition the front brake and the clutch lever. I loosened the 8 mm bolts and I angled down both of the levers for better economics. Then I rode the bike out of my neighborhood, and when I went to about 4000 RPMs and gave it more gas, the RPMs went up to about 8000, but the bike did not go anywhere. I shifted up to the next gear, and gave it gas and the same thing. After about 4000 RPMs, it seems like the clutch is not engaging. Also, when I down shift, usually, I could feel it catch for lack of a better term, but when I downshift the bike, doesn’t really respond.
My first thought is that the clutch failed. But it has such low miles, and I have been very conservative with this bike because I am not 100% used to it.
Or can the clutch literally just go bad like that???
The dealership said that the clutch could go bad at any time. Even at 12000 miles.
I am on a couple pages on FB and 95% of people said slave cylinder.
And 100% said the dealership is crazy lol
And to add, if I am just cruising in fifth gear at like 50 mph, just to see what it does while i was troubleshooting, if I give it a good amount of gas, the RPMs will just climb and the bike barely accelerates.
I ordered a slave cylinder rebuild kit that will be here today.
I took apart the master cylinder and rebuilt it. All looked pretty good.
The slave cylinder was another story.
When I took it apart, I had the cylinder housing in my hand.
I had to push HARD with my thumb to get the piston to go in. Like VERY hard. And when it did go in, it stayed at the end of the inside and took several seconds to “naturally” come back to flush. (Still didn’t go all the way to flush)
I had to tap it on the ground for it to go back “flush”.
Then I did it again. Very hard to push in with my thumb.
I took it apart and took compressed air to “pop” it out of the housing.
It had junk all over it. The spring looked corroded and the black rubber seal was kinda hard. At the bottom of the housing was tiny chunks of black and brown.
I took a very light scotch bright pad and brake clean and smoothed out the housing and the outer surface of the piston.
Despite the fact that I am getting a new kit today with spring and seal and nipple, I reassembled to see how it felt in my hand.
The piston slid back in the housing with the spring like butter. Smooth as silk.
I was able to press it in and out MUCH easier. And the spring had enough “spring” to push the piston right back to flush.
I hope to assemble today and have good news!!!
Does this sound like the issue?????
