  6. 5th gear slipping

    Engine Discussion
    Hey all. I have a 1972 CB350. Just recently the transmission has started slipping while I'm driving in 5th gear.

    Just discovered a broken gearshift spindle on a 1971 CB450 (the part that engages on the shifter, about an inch from the pivot joint), two questions- would the gearshift spindle from a 1974 CB500T work (I have a donor engine) and other than general fatigue what might have caused this break? Just...

    Engine Discussion
    Hey there, I´m having this issue with my 1978 CM185T. When i put it in first gear and start to go, it pulls down the kickstarter and leaves it down making a sort of ratchety noise.

    Hey, I have a '81 CM400T I picked up dirt cheap late last year. I threw a couple hundreds bucks of fluids, tires, couple of minor aftermarket parts. Mostly maintenance-y kind of things. Long story short, I put about 1,100 miles on her so far and the past little bit it seems to be slipping out...
  20. CL175 Clutch Problem.

    Engine Discussion
    Hey guys, first time poster. I only came here because I thought it might be worth asking advice before tearing the engine out of the CL175 to replace the kickstart shaft that's not functioning. So, a little background on me: Owned a few vintage hondas, I've rebuilt some engines and...
