Topic: clutch problem

[Cataixo]

Hello
I have a problem with my cb750 k2, the motorcycle when the engine is cold, the gears work correctly, but after 20 minutes of driving, they start to fail at the time of passing from 5 to 4 and 4 to 3, I have to wait for the engine lower the revolutions a little so that they enter without scratching the sprockets,I have changed the friction discs, springs, O-ring shift , modified the basket so that the clutch has more oil.
oil pressure is 65 psi at 3000rpm
I don't know what to look anymore.

Pd: I'm sorry for the misspellings, I'm from Spain and I use the translator

Greeting from USA,

You may have problems getting help as translated.....

🤔 SCRATCHING the sprocket may be the problem.....🤔

' Scratching the sprockets'...I get it. Grinding the gears when you try to change down. I think you have a broken shift arm spring . No. 1 in pic.

Tracks, hang around here long enough and Lars will have you understanding Viking, right Ray?
Cat, your clutch problem when warm only may be an adjustment issue. When cold, check the free movement of the clutch lever on the clutch cover. You should be able to move the end with your finger no more than 1mm or so. This is best set, IMHO, by loosening the lock-nut, turning the slotted screw in or out, tightening the lock-nut, and checking again with your finger.
