Need help - bike not starting


Ion

Recommended Posts

Today I cranked the bike, waited for her to get warm and left my community. Two blocks down the road she stalls as if it had no more fuel (It has fuel)

Tried to cranked her again and it turns but doesn't start.

Let her rest for a few mins. Started again and withing 30 secs stalls again.

It sounds to me like a carburetor issue but have no idea where to start.

Also, the fuel pump didn't make any noises when it first started which did call my attention. After it stalled I tried the old trick of tapping the fuel pump but didn't do anything.

Does anyone have any suggestions?

 

Thank you

My did the same. Sounds like fuel pump. They can fail completely or be intermittent. I went aftermarket - any auto parts store should have a Mr. Gasket 42S but you need to be sure to shut your fuel off every time you park the bike since it doesn't have a check valve.

 

Other options are to replace the contact points in your pump or use a pump with a check valve. Search for posts as there are many

ION Mine was on its way out I suspect. Only time I had problems would be swaping from main to reserve. Soetimes it was fine, other times it would caugh and not gain speed back. Let it sit a few minutes and all was good. I changed out the pump to the Mr Gasket 42s on recomendation from some fellows on another board and what I read here. I made a write up over there with some pics. Its also submitted here and when Freebird get the chance he will get posted.

Thank you very much for your replies. I will start with the pump and see what happens. If the Mr Gasket 42s requires to shut gas off when turning the bike off I don't think that is a good fit for me. She is my daily ride and I know I WILL forget often. It is good to know your weaknesses.

Since OEM are known to eventually fail, are there any other aftermarket alternatives?

That's where I'd start. At least check them. $35 to replace.

Save yourself some grief and get the Facet 40171. It has a positive shut off when the key is turned off. If you do not close the fuel petcock and with a full tank of fuel you have the potential of fuel leaking past the carburetor and into the cylinders. This will give you a hydraulic lock that could damage the engine or starter. At the very least it will scare the hell outta you when it locks the engine. Don't ask how I know. Oh and contaminate the oil! :(

 

Having said all that I would opt for replacing the points as the Facet 40171 requires coming up with a way to mount and requires fittings and possible additional hose. I have some pictures I'll post shortly. While your in there might as well move your fuel filter to where it can be changed easily. :080402gudl_prv:

Ok here’s the pics of the Facet 40171 installation. You can get it at aircraftspruce.com. Around $45.00 if memory serves me. You have to procure the fittings at the local ACE Hardware or an automotive shop. I installed the pump at the existing pumps location and I attached it using a self tapping screw and a tie wrap. Make sure it is located so the cover that was removed can be reinstalled. Don’t ask why I know! The hole I drilled was made with a 90 degree drill. I had the 90 degree drill but you can probably get one at Harbor Freight. That attached the top of the pump. For the bottom I used a tie wrap. I cut the existing electrical connector off the original pump and soldered it to the Faucet pump making sure the 12 volt supply and the common were correctly connected. While I was in there I relocated the fuel filter under the seat as recommended in an earlier post.

 

This was all done before someone located replacement points. Had I had that info I would have opted to replace the points as this was a pain in the a**. I do not recommend using a pump that does not have the shut off feature. If you have a needle and seat that does not seal, fuel has the potential to drain into a cylinder and give you a hydraulic lock. :080402gudl_prv:
