Your right, the shift fork riding on the selector drum is very cool. Little details like this make watching you swear an old motorcycle engine for hours totally worth it. :) Keep up the great work.
No.1 how sure are you of the location? Engines have a habit of masking the source of a sound. Use a metal rod to help narrow down its location. No.2 Are both cylinders firing? No. 3 How many miles has the engine done? A little bit of history will help. No. 4 Worst case if you've thrown a rod bearing. If this is the case then the work required to repair it is quite substancial. Hope this helps - matt
Any idea on how to prevent getting gungy oil in the sump like this bike did? I take it this happened due to the bike sitting for a while with the same oil?
+Bikers Quest pretty much yeah, I check the oil with a magnet then washed the oil down with petrol and poured it through a coffee filter and checked for ally shavings. Everything was good - but yeah the fatc that its been sat for 8 years getting hot and cold as the seasons passed cause the contaminated oil to coagulate. Modern oils have anti-foaming agents and detergents as additions to help clean particles within the engine, when these sit for years with contaminates within they coagulate to hold the particles. This forms a sticky crappy paste. This is why diesels needs different oil as the anti-foaming agent reacts with diesel and messes everything up. Cause the oil to turn into a tar like sustance. To answer how to stop this from happening, changing oil regularly is the best prevention. Using a thinner oil in winter also helps greatly, and reduces wear during the colder months. If a enigne is being used or not the oil should be changed every 6 months, filter included.

Jesus christ, I've only really worked on dirt bikes but that clutch chain is a beast. Thank fuck for direct gear driven clutches.
Is it possible to change the piston rod bearings by just removing the oil pan?
Sorry mate you've lost me with piston rod bearings? If you mean the rod bearings then no you can't.
is it posible to replace the outputshaft oil seal without splitting the case?
Got a loud knock. seems to be coming from the left lower side of motor. Any thoughts?
