Here is my concern : I experienced some grinding noise on 1st (not to speak about reverse, but I know there's no sync on it), 2nd and 3rd gears (4th and 5th seem to be ok).
In order to avoid going into big expenses right from the start, I began by checking the clutch command : I replaced the master and slave cylinders, and changed the red plastic tube for a braided hose - all sourced from PIM.
Everything is ok when cold, but when the temperature rises (after approx. 15 or 20 miles riding), the grinding noise comes back.
The clutch seems to disengage correctly - no creeping when in gear, for example.
Having decided to get the transmission inspected, I rode the car yesterday to thoroughly identify all the issues, as I don't want to discover a new one after a partial gearbox rebuild...
Doing so, I discovered that the grinding noise (in 2nd and 3rd gear, at least) seems to depend on the de-clutching speed, i.e. if I depress slowly / calmly the clutch pedal, grinding noise occurs maybe 8 times out of 10. On the contrary, should I depress very quickly the pedal and shift (quickly, too), there is no problem...
I'm therefore no more certain that it is strictly sync-related : could it be that the new clutch command is still faulty - or out of adjustment ?
I'm aware that the first syncs to be at stake would be the 2nd and 3rd as they are the more loaded, thus likely to be worn and in need of an overhaul, but the cost isn't the same
Did you encounter this kind of problem ? What's your opinion about this ?
Thank you in advance for your replies.
