If the bike is fuel injected, the module should fix it. If the bike is carbureted, you don't need the module but you will need to re-jet the carb to enrich the mix.

should be an adjuster between the cylinders. Looks like a threaded knob. Sometimes you have to pull it out a little first.

i had same with my vtx 1800 i adjusted the idle , if you look to the left of engine between the pots there is a little plastic wheel on the end of a cable which goes to the throttle body, i think it is anti clockwise to increase. try this it worked ok for me however there is a cold start on these and it is operated by coolant temperature check your coolant level and top up if neccessary with the correct coolant as specified (not got info at hand)

did you sort this out? getting same issues and by poular result it seems to be the fuel pressure regulator.

1800r 2005 vtx shifter sticks and have to pull it back up to down shift, how do I fix that .

You may have a bad spark plug wire or a faulty ignition coil. Use an oli car spark plug wire to run a test case to see if this resolves the problem. If only on one cylinder, trace the wire back to the coil and have it tested or replaced. Good luck

I would check the electrical feed to the pump. A messy dangerous business to work on as it will pump fuel everywhere if you are not carefull
Hope it isn't the pump!!

Hi and welcome to FixYa!

Looks like the ignition coil is worn out. It starts good on cold for the ignition coil is not forced yet and when the engine is warm it fails to start for the coil is hot. I believe that once the ignition coil is replaced you'll be good.

Hope this helps and thank you for using Fixya! Have a good one!

Locate the radiator cap under the left side of the tank , or under the left side cover, and add 50/50 non-silica formula antifreeze there. Then top off the overflow bottle down by your left foot to the high mark. The fill cap for the over flow bottle should close to the radiator cap(within a foot).

that is 100% normal, it is condensation and all exhaust systems have a little drain hole or they would rus out in short order

Push the starter button , if the solenoid clicks the button is good. If not check the button for continuity. Follow the positive battery cable to the solenoid. Jump the solenoid posts, if the starter works , you need a new solenoid. If you hold the starter button and tap on the starter with a plastic hammer, and the starter works, you need starter brushes. If you open the starter and the armature is shorted or the coils are grounded or burnt, replace the starter assembly.

Hook it back up to the computer and reprogram the power curves. Reprogram it the same, you may just have developed a small glitch that came on all by itself. Also check the website on line in case someone has a better map available to try. Be sure to account for all changes you made to the stock set up.

the easeist way is to make a junction on the brake line so the 1 line hooks to both hose fittings. this will do what you want and you don't have to come up with some kind of cap to cap off the unused hook up.

Kick stand is down bike won,t start. Bike has a safety engine stop on kick stand. Try to start with kick stand and the way in the up position. see owner's manual

check the starter switch, some break inside and only part of the connection is lost. it's like an ignition on a car that has half the contacts touching

You might have to drain the fuel tank and check inside for possible contamination, try to pull the tank off, remove the seat and study how it is attached to the frame, sometimes the interior of the tank starts to flake off.
I believe due to gravity feed to the carb, they may incorporate a filter screen in the line coming out of the tank, once you pull the tank you will have a better idea.

Its not recomended but it can be done if you drill a hole in the middle of the dent then use a puller to pull the dent out. then you will have to spot weld the hole you drilled grind it flat lay a coat of bondo on it sand it smooth then get it repainted. Ur better off just leaving it and make up a good story on how the dent got ther

mcdevito75 Here, Don:t know too much about bikes but my immediate though is lose of compression, specially if this is a 2 cycle engine, (oil mixed with gas) Have the compression checked, may be a very slight crack in the cylinder head or gasket.

you will need to cut the old ones off first with a very sharp knife
the new grips just push on but there very very tight heating them up in boiling water may help them go on but be fast fitting them on

If you have a custom frame you could probably put about any engine on earth in there provided that it actually fits. If you want simplicity HD, Revtech, and Ultima are all "Harley Clones" and there is a never ending aftermarket for them. Lots of options for transmissions, accessories, power level, etc.

The VTX1800 engine on the other hand puts out just as much (or more) power and has something that the HD engines don't: A reliable track record. Down side to the VTX engine is that it is electronic and liquid cooled adding a lot of complexity to the build but if you're up to the task it'll be worth it. With the VTX you're pretty much stuck with the transmission Honda bolted to it, which is a shaft drive.

If you use an "HD" type engine it'll look classic, the sound will be un-matched, and when you're broke down on the side of the road it'll look freaking sweet for the other gawkers who are trying to help you figure out where the oil is squirting out.

If you use the VTX engine, likely you'll be the only one who'll ever know it's not an actual "Harley" type engine and it'll run to the end of the earth and back a thousand times without issue.

For the record I actually OWN a '96 Harley Davidson so I have an idea of what to expect.....they ****. If you can figure out how to use the VTX engine go for it.
