Greetings bad-folks!

I've just got the Ulysses back on the road this summer after 3+yrs of sitting with busted front header studs...A guy up the road cut my header and replaced the studs then welded the header back for the fix!

Super stoked, I then proceeded to rebuild the forks, replaced new steering bearings, new belt, new O2 sensor, new spark plugs, new muffler actuator, new intake seals, cleaned the injectors, fresh TPS reset, fresh primary fluid and adjustment, synthetic 20w-50, new led headlights, new rear tire and more, just about the whole nine yards.

The bike ran great for the last couple months, until this week when I started getting a little noise from the engine. I attributed the noise to the synthetic, since it's been super hot here in TN, and I figured a fresh oil change with conventional oil might help make things a little quieter. Yesterday the noise got louder on the way home so took the back roads to keep revs low. I dumped the synthetic and went with Dino oil with Lucas oil stabilizer and fingers crossed but to no avail. The sound is a knocking in the lower half of the engine.

From what I've read, maybe it's a rod pin or rod bearing possibly?? The engine has numerous fittings that weep, the rear cylinder has a slight weep at the base, as well as a more substantial one at the head gasket, but never leaked enough to leave a drip, or need to add oil. Maybe oil starvation could be what lead to my trouble, or maybe just regular failure of a weak pin?? It is now being parked until I can get this worked out. The Ulysses is my backup to my daily drive old Kawasaki Concours, looks like I'm riding the mule again, no more Buell😥.

Any ideas on how I should tackle this on with a limited budget, I imagine I'm either into an engine swap or rebuild? Any possible leads?

Thanks much,

Sounds like youíve analyzed/surmised reasonably about the noise. Might be worth checking the primary chain tension though.

Switching to inferior oil not good! Stay with the synthetic. It holds viscosity at temperature WAY better than conventional oil, which begins to cook and rapidly break down at temperatures that donít even phase synthetic oil.
