Hi , i have same bike and the only problem with my bike is that when i ride it for 20-30 minutes then park it then when i try to start my bike again after parking for 20 minutes it wont start the fuel comes in the exhaust or i have to try multiple times and also i have to crank the engine a lot to start the bike and after starting it runs fine or after cooling down or after few hours it starts fine. Or sometimes when its idle it starts stalling. Can u please tell me whats the issue?
The first thing I would check would be the ignition coils. The symptoms you described are commonly attributed to an ignition coil failing after heating up/expanding, then functioning again once cooled down/contracted. I can’t guarantee this will fix your problem, it’s just the first thing I would test
Spoiler alert: there were many problems, but the ultimate one that kept the bike from running was accidentally swapped main jets. The customer got rid of this bike months ago, so I will never see it again, but I’m told that it’s running great and being ridden regularly. 👌🏻
If I have a bike like this, the first thing I would do, if this hadn't been done already, is attach a fuel level gauge to each of the bowls while the carburetor is installed on the bike and see where the actual fuel level is. And if you can get the bike to be running while the fuel level of each bowl is being checked, so much the better. My guess is that the fuel level is way, way above where it should be. Adjust float level as necessary. That would be just the start. If that doesn't work, return the bike as much as possible to stock condition. There's been so much tinkering with this bike that it's impossible to figure out the main issue, or combination of issues. Also, hyperchargers may look cool, but I don't believe they do anything for the bike that would justify the expense.
I love to hate these bikes. I have built and rebuilt them from the frame up. It’s so hard to find or locate a problem when you’re not seeing everything.
Have you tried the air/fuel mixture screws? They may be too too far in to idle. Have you balanced the carbs?? Neither was addressed in the video. Are you running the stock air box? There may be an air leak. Did you mix the main jets? the rear carb has
The bike is long gone now, but these are all excellent suggestions. Mixture screws were tested at several different settings, I seem to remember them being about 3 turns out, but I’m not sure. I never got the bike to run long enough to balance the carbs. Air box was aftermarket - hypercharger - and was properly secured. I was not aware of the difference in the main jets, that may have been the ticket. The owner traded this bike after we couldn’t get it sorted out, but apparently the new owner got it up and running
Ok I watched the second video. I am exactly where you’re at. Did you ever happen to find out the fix Sherwood appreciate the info your vids were great.
So I just bought a 2006 vstar 1100 and I bought the bike running and trailered it home it started the first time at home but ran into a similar problem but also I can’t get it to start ignition makes a noise but nothing else
If you’ve got a good battery, and everything leading up to the starter is working properly, you may have a problem with your starter or the starting clutch. Evidently the starting clutch is a weak link on these bikes.
I can't take any more of this " tinkering". The floats are definitely sticking or float level messed up. Keep cranking it while playing with the throttle and you will be replacing a starter clutch
You’re absolutely right, the floats were sticking. I very likely did do some damage to the starting system with all the cranking, but the bike is long gone now 👌🏻
Your float needles are not seating right. They are not sealing off the flow of gas when the float raises up. Did you check the floats and make sure there was no gas in them? Even a pin hole in a float allows fluid in them and they will not shut off the gas flow. Your fuel pump always priming is the giveaway either the floats are bad or the needles are not sealing off with the float.
That was an issue, you’re right. The main issue ended up being with the jetting. It was way too rich. The bike was only running when the owner bought it because whoever had last worked on it left everything loose. There were huge air leaks, and tightening up the loose parts made the bike dump so much gas into the intake that it was just constantly fouling the plugs. The owner traded the bike, though. There’s more details in the next video if you’d like to check it out
With gas that old having been run through the carbs, my bet is a piece of trash was holding the needle off the needle seat just enough so that the valve didnt close causing the flooding issue. Those carbs needed to be cleaned bad.
It was rich jetting, dumping a whole lotta fuel into the cylinders and fouling the plugs. The owner didn’t feel like going through the process to get it figured out so he traded it
Lol, if we still had it I might take you up on that. The owner traded it for a 650. We were going to have to start fiddling with the jetting on it and he didn’t want to fool with it anymore
Well the fuel pump is not working as it should. You can hear it trying to prime itself every time. That much gas from the exhaust means there is constant gas flow. Are the gas lines to and from the pump the wrong way around?. The easy way to isolate the problem is to bypass the gas tank and fuel pump. Just feed gas directly to the carbs and see what happens.
Definitely was dumping a lot of fuel, a float adjustment took care of that. The jetting was too rich, and the owner didn’t want to mess with it anymore, so it’s been traded 👌🏻
My bet is the needles have something on them preventing the needle seat from fully closing. And my bet is when the carbs were cleaned the needles were overlooked as was the needle seats. I had the same issue with mine when i got it.
Regulator/rectifier terminal? I've just tried to start my VN750 and met some problems with it. Checked regulator resistances (according to manual) and found out - my regulator is dead. Also I'd check high voltage wires from coils to spark plugs and coils (sometimes it works on high rpm and cause pain in ... at low rpm).
Yes, among many other things, lol. The issue ended up being incorrect jetting for our altitude, but the owner is in the process of trading the bike so it's a dead issue
