Did anybody actually read his question? He was asking about a noise in his "shsft drive" motorcycle near the final gear assembly.
To me ot sounds like the backlash is out of adjustment and/or the rear wheel tooth contact needs adjusting.

main engine heat sing up side have 4 bolt.open it clearance pocket inside.

timing chain is auto adjust, if you hear it rattle, it has come to the end of its life, and must be replaced. They usally only last about 40 - 50,000KM at the most.

Hey, Martin. There are two mounting screws that stick out of the back half of the housing just behind the seam, one on each side with their heads pointing downward a bit. Take them out, then tap the top of the front half to disengage the front half tab from the back half stop, and the front half should just drop forward into your hand. If you have the new bulb already, put on vinyl gloves -- the kind a doctor would put on before doing a prostate exam -- before opening the package it comes in. (Skin contact with the new bulb is a no-no, for the sake of the bulb.) Disconnect the modular connector from the bulb and gently remove the dust cover. Change bulbs, reconnect, snug the front half back into the housing (be sure that the word "TOP" is at 12:00), carefully reinstall the mounting screws, and you should be good to go.

There are two screws on the carb itself. Those are what you adjust by small turns at a time to get your high side and your low(idle) side. Small flat screwdriver is what you need to use in most cases.

Turn the mixture screw all the way in & then turn it 1&1/2 turns out. this should allow the motor to start

i had the same same problem with my 1992 vulcan 750. more than likely it is your reserve lighting devive located on the right side battery box. have you had a problem with your regulator/rectifier lately or a power surge of some type?

According to information I have found this model uses what is called a Stator to keep the battery charged. If you aren't knowledgeable about Stators, check this video out: http://www.youtube.com/watch?v=MWU2TbEePsY&feature=relatedThe following is a website that shows a inexpensive repair. http://www.vn750.com/forum/showthread.php?t=16839

It is likely to be the diaphram. The valve uses vacuum set up by the diaphrams to operate. If either is leaking, the valve wont operate.

You can first of all check the universal type with a +B on the one side and the body grounded to give the output at the center. If this is tested on the left and right sides then the flasher unit can be used. Otherwise there are many models of this type that will work with +12.Try the electronic types.

Your starter button is dirty or bad. The starter button does two things. Push it in halfway and the lights turn off to put more power to the ignition and starter. Push the button in all the way and the solenoid engages. Try cleaning the starter button. If it will not work after cleaning you may have to buy a new right switch assembly.

Could be a bad starter or malfunctioning compression release, or a seized engine. Try pulling the spark plugs and spin engine. does it act the same or does it continue spinning without drawing down?

check fuses first... if ok, buy an electrical tester from walmart for $5 and see if it's getting any electrical to the headlight.. if it is.. replace bulb

It's at least a good starting point.

It is just a vent tube. It runs down to the ground. If you look closely, you should have another that also runs in front of the battery and to the ground also.

first change all the plugs then swill all the coils with WD40 i think its just getting bamp?

hows the battery voltage, 13v is good...if battery reading is a lot lower than this and over three or four years old... id change it out. but you can do a quick charging system check if you have a multimeter..with engine running run up the rpms to about 3to4 grand and watch the meter it should rise in voltage maybe getting up to 13.5 or 14volts and then as your still reving it it should regulate back down to about 13v. regulating system is good!

Sounds like a loose wire in the battery box somewhere. Or even under the seat is where the wires run after leaving the battery box.

ok buddy on the carb will be some sort of screw and idle screw turn this in 1/4 of a turn with the machine running until it idles at 1000rpm also the choke will stall the engine when warm the choke is only for cold starts get back to me more info or problems
