Hard start when engine is hot

Postby nitefuzz » Wed May 07, 2014 1:59 am



I have been finding that my 98 SE is starting hard after it is completely warmed. It acts like it is flooding itself. I have noticed a strong gas smell after I get home and park it in the shop................... does anyone have some ideas for me............. maybe the petcock needs to be rebuilt????? Any ideas or thoughts would be appreciated.

Is it not cranking well? Or is it cranking normally, and just not starting?

it cranks normal but seems like it is starving for gas............. or like it is trying to flood its self. I have to give it some throttle and then its fires and runs fine. If it is completely warmed up from a long run, and I shut it off and then restart it within 10 to 15 minutes it starts fine, if it sits for 30 minutes then it starts hard?????? any suggestions or is it just the nature of the beast.

I purchased a new fuel filter and am going to change it out. (its not an Emgo, I purchased a filter from the local NAPA parts store and am going to try it, I seen where guys are using the NAPA filter 3011, after looking at the 3011 filter, it does not have the barbs on the connections for the clamps to lock on good, my NAPA guy showed me the one he recommended that has the barbs on it so I purchased that one)

how old is the battery?...how clean and tight are the connections at the battery?
1500s use a lot of juice to spin the starter...it takes more ( power)when the starter is hot...it "steals" the power from the coils and the plugs don't fire...the mixture goes "rich"....

One or both float bowl gaskets might be leaking emptying/lowering them. Do a visual check of them and the spark plugs in addition to a charging system check and battery load test.
This is what I do
Local and need repair help with your 1500, Valkyrie or ST please PM

My 98 has done this exact same thing since I bought it. I feel it has something to do with pressure it the tank. As it will not start hard if I stop and get gas then start it and take off. I usually give it a bit of throttle when hot starting it, that will help also.

Battery is new last summer................... any input on the fuel filter I am going to try, it is a NAPA 7-02323, it has both 1/4 inch and 5/16 inlet-outlet ports.

What size of outlet/inlet ports dose the Honda OEM filter have?

Fuel filter won't make any difference.

after lookiong further into the NAPA filter it looks like I need to take this one back and get the filter with the part number of #3003, it has the larger 3/8' inlet and outlet ports.......... does anyone know exactly how big those ports are supose to be. I am thinking they are 3/8' but not sure until I get the filter off and look at it, I would like to have the correct one when I do this so I can get it back together right away.

they measure about 0.410" in dia....3/8" should work ...or in a metric world 10mm in dia.
filter is appox 4" long end to end...body is about 2 1/4" long, appox 1" in dia.

how does the bike run under hard acceleration?...does it miss or lack performance?..may need a new fuel pump or rebuild the "petcock"
hope this helps

The OEM filter has a 13/32" outside diameter port on each end. If you include the barb diameter in the measurement, it is 7/16" diameter. A filter with 3/8" ports will be a thirty-second of an inch smaller than OEM. If it has a barbed end, you might be okay using it.
