Hey everyone. I'm looking for some help on this particular problem. It seems very unique and uncommon because I can't find any other topics on it, whether vstar or any other bike. Basically bought this bike a few months ago and it runs amazing, except for one little flaw I noticed. If I drive the bike on the highway for over 20 minutes, then park the bike and go to start it again within 10 minutes, I get aloud TOC! noise coming from the engine on startup. I'm thinking starter clutch maybe, but I'm really really unsure on what this is. This never happens when just riding around town, or on cold starts. Only after riding the bike on the highway for awhile.
Work done on the bike so since June:
-Acquired Bike and noticed it ran a little lean
-Replaced K&N air filter with Stock, bringing air/fuel mixture back to normal
-Oil+Oil filter change
-Spark plugs changed
-Brake fluid flushed (Front and Back).
-Carburetor boots surface cracked. Sealed with High Temp Rubber Adhesive
-Carburetors taken apart and cleaned (clogged pilot jets)
-Idle adjusted to 950-1050 RPM
-Fuel completely drained and replaced with fresh fuel
-Air Induction System removed
-Final drive oil changed
Here's a video on it. It might be hard to hear if you're listening on a cell phone, but basically you'll hear a TOC or CRACK noise right when my bike starts.
