You should have probably adjusted the clutch cable before jumping into that. It would be very hard to guess without hearing it. I will say, it shouldn't be that loud. First gear clunk always is loud, but not subsequent gear changes. Has the oil been changed and what type are you using?
Oops, should probably have mentioned this, I did fiddle with the cable adjustments a bit as well. Tried soft, medium and very tight and all was the same (very tight might have alleviated it ever so slightly). Apparently it was serviced not too long ago and I'm not sure with what oil. I recon I'll service it myself rather just to be safe and also not a 100% sure, but there seemed to be a slight whiff of fuel coming from inside the motor when I pulled the clutch cover. I like Castrol Power1 4T 10W50 so will probably use that.
Mine seems quite loud (only in the lower gears), but I'd check your chain adjustment carefully as on mine that makes a big difference
I replaced, what I believe to be the original DID chain, last week and at first erred on the looser side of the manual spec but have since tightened it up to the tighter side (on side stand, 25mm play just behind foot peg).
Beautiful 12. Love the silver.
Have a look at the ecu plugs. If the ecu has 2 large plugs itís a A1. If it has one large and one small, itís a A2. Ive not noticed that my gear boxes are ďloudĒ.
These 12s were made to be silver ... they have engines strong enough to fly a small plane, they have canards and being silver they only need the wings still 😉
Confirmed, it's an A1, thanks cmg, been trying to find ways to figure it out but the VIN search didn't pan out.
I'm starting to think the noise when shifting is due to the clutch not fully disengaging when pulling in the clutch lever as when I do clutchless up shifts its not noisy at all. The friction plates all seem to be within spec 3.2mm and look ok to me but some of the metal plates have some discoloration and I suspect are ever so slightly warped. I don't really want to fork out for an entire clutch kit at this point, can you get only the steel plates and would it be advisable to only change them?
PS. Already sorted that darn regulator plug as it was just starting to give problems (looks like someone tried welding in there 😅). I chopped it off and soldered the cables directly onto the regulator. Hope it was soon enough to let them live long and happy lives.
