My motor tossed a rod bearing. Looking to purchase a running motor in America.

Final conclusion of this saga. Pulled oil pan to check tensioner. Turns out my Cyl #3 rod bearing at the crank ( right next to that primary chain tensioner) ejected itself and the rod was moving back and forth on the crank. Time to hunt down a motor.

Unfortunately neither of these sites have any stock, its been extremely hard to find anything. Id be interested in knowing what these after market performance ones are from new Zealand though!

So I have tracked down a ticking/ knocking noise to my primary chain tensioner. I cant seem to locate any New OEM tensioners anywhere. Does anyone have any places worth checking for inventory on this item? Does any one have tips for maybe refurbishing my tensioner if none can be found? Thanks.

Also compression across all 4 cylinders was 155 psi +/- 1 or 2 psi

Update, took the bike to several shops to have them listen to the noise and issue I have. Everyone agreed its probably valves. Its in a shop now, so I'm just waiting to hear back what they find. Will update as I find out what's going on.

good to know, great info. valves have been adjusted relatively recently actually, but I did not own this bike prior to carb rebuild and valve lash adjustments, I am just working out the kinks on this bike I purchased.

But then again, bike just turned over 20k miles so I feel as if that's a little too soon for low compression.

I am doing a compression test very soon so ill know more on that.

I'm posting here to see if anyone has tips in helping me figure out my issue. So my Cylinder 1 plug keeps fouling after a short period of time, I can hear my motor pinging then the plug will foul. No oil or wetness on the plug when I pull it, just a lot of black carbon build up preventing...
