sorry for the question but this is bugging me and I need to ask. I recently posted about a stuck/stripped oil bolt. I have been pounding on it and even tried to heat it up by just letting the it idel and tried to turn the bolt but it just keeps turning in a 360 and not coming out. Recently I have been trying to start it to keep the carbs clean (just had them done) as I don't want them to get clogged. I then started having problems with the bike ideling and now it just won't start. If there is just a enough opening to let the oil pressure out would that create a no start situation. I have worn the battery out and had to recharge in trying to get it started. Now it just cranks. I think that - until I get the oil drain plug redone and the plug secure that it won't start as it needs the oil pressure for compression.
Take it to a dealer or honest independent repair shop if you want it running. Amateurs sometimes strip bolts that only professionals can fix proppaly.
You don't need to keep starting your bike to keep the carbs clean specially if you ride it regularly. It's like starting your bike/car in the winter to keep the battery up. It's not a good thing to do. Buy a F%$#ing charger. All your doing is creating condensation in the engine and contaminating your plugs with fuel then they will foul. Nothing gets hot enough to burn off the contaminates. Don't keep using fuel additives either. Seafoam may be once a year at the proper amount. Want to keep the gas out of the carbs so they don't gunk up. Shut the fuel off, run until motor runs out of fuel and then crank a couple of time with throttle closed to clear the idle/starter circuit. As far as the oil drain bolt, I'm surprised it's not leaking a tiny bit of oil now. Somebody stripped the threads and it need a proper repair.
thank you for your replies. there is actually a little oil now below the oil plug area. If the plug is open just a thousandth of an inch and the oil pressure has been released would that create a no start situation or as mentioned, starting it and shutting it off possible contaminated the plugs.
The short answer is NO. The long answer is that you don't seem to understand how engines operate. The crankcase is vented so there is no oil pressure in the sump. Combustion pressure is generated in the head and is not part of the oil circuit. Oil pressure is created by the oil pump to circulate oil throughout the engine. It is not required for starting... but it sure helps the life of the motor to have some.
Thanks for the reply. I know a little about engines having watched a lot of animated youtube videos. And I'm taking an engines class this semester at a local community college. My thoughts are that when you assess a no start situation you need to rule things out. From now on I won't need to address oil pressure since you answered it but then you never know as new engines are being developed but for the Honda V-4 engine I now know that oil pressure is not an issue in a no start situation.
Is it the Sump bolt that's stripped? The dealer idea is good but if you really want to sort it yourself (since your doing course etc..) I suggest get a replacement sump pan from a bike dismantler, take your plugs out and clean them, charge your battery and see what happens. If it starts take it for a good ride to burn off and work through any crap/old fuel build up - The down side to this is you may still end up having to take it to a dealer - but I'd personally try this first.
