So I'm prepping the C2 for the upcoming MOVMX series, I got new shocks to replace the blown Boges and worked on jetting which I think I have pretty close.
I encountered an oil leak at the bottom of the clutch side case which I resealed and slowed but didn't stop the leak. I also noticed seepage around the kick started seal and believe it or not, around the oil fill plug. When I was working on the rebuild I made sure the vent PIPE was clear. It dawned on me today after all the break-in time and a short track day that maybe I'm building up some crank case pressure and the leaks are coming from the path of least resistance.
I pulled the vent HOSE off and tried to blow through it, couldn't!
I didn't have a piece of hose today so I poked a clothes hanger through the hose to dislodge whatever was in it. There was some sandy mess in there that came out pretty easily once I broke the seal so to speak.
Here's the question...I've run the bike for probably 2 hours total since rebuild. I replaced the crank seals and the countershaft seal but not the kicker seal at that time. What are the odds the right side crank seal is bad now? I haven't noticed any odd smell that might indicate transmission oil in the crankcase.
The lesson here is to check everything and don't think the weirdest things can't happen!
