Hi all, i got a 2001 drz400e with 4000kms on the engine that still had the ACCT installed. i ordered the MCCT from the store and when installing it on my engine i noticed that the ACCT was fully extended when i removed it (removed spring before removing the ACCT from engine). Would i be correct in assuming that it is likely that the timing chain is stretched quite badly? also during the install i couldn't find the marking for TDC on the crank inspection hole, only what looks like some drilled holes for balancing, and also the plug for the bolt to turn the crank directly was seized and the hole for the allen key was rounded out. I think what needs to happen would be to replace the timing chain, along with removing the left side cover to drill out and remove the engine plug to replace it. while I'm at it i will also do the loctite fixes on the primary and counter balancer nut since i dont think they were done by the previous owner, considering that it still has the ACCT. even before replacing the ACCT there was some distinct knocking sounds from the engine at idle, but once it revs up it appears to go away, does this point to the primary or the counter balancer nuts being loose? Any words of advice on what i'm about to do to my bike?
