2004 kawasaki VN 750 Vulcan - Answered Questions & Fixed issues

Intermittent faults are difficult to locate and occasionally the cause is never found. Often the problem cures itself or somebody cures it by desperate and mindless fiddling but doesn't know how. I tell my customers to persevere and eventually a pattern will emerge - the same corner, the same stretch of road, the same sort of weather, the same speed, the same gear, etc.. Once a pattern is recognised it increases the chances the problem can be repeated predictably or some serious detective work might provide further clues. Fitting temporary telltale lights to monitor supplies and grounds around the circuit can be helpful. I have had two cars where the intermittent fault was inside the ECU. Very difficult to prove and too expensive to replace without justification. On one car I was lucky and had a timing light connected when the fault happened. I watched the timing mark move and keep moving until it was almost out of sight and the engine stopped. It restarted immediately and ran normally until the next time.

I believe there are a couple of bolts inside the "toolbox" in the backrest that need to be removed before the seat will come off.

sounds like a temp. sensor malfunction.

An engine is an engine, whether a car or a bike engine. Synthetic engine definitely is better for all engines. Better lubrication, longer life, longer time between oil changes thus more savings on servicing charges etc. Go ahead.

The speedo's are 100% mechanical. If there is no cable conencted to your speedo, you found your problem. The cables are prone to break right where they make the turn to head up to the speedo from the wheel sender. A new cable is about $20 dollars and is easy to replace.
I hope this helps.

could be faulty oil pressure switch

Have you tried to talk to your Kawasaki dealer or go to Haynes website to look for your repair manual. Well mate, in this world nothing is free anymore even the air is getting pretty close to be charged for carbon foot print tax. Good luck

you must have a fault with the sensor buddy replace this or the connections are not in correctly or is this the oil pressure light

I would check the fuel flow and the timing to make sure that your not getting to much fuel and that you are getting spark at the correct time.

one of two thing's comes to mind, either inside the Headlamp,(or) under the gas tank, you either have a loose wire, or a blown fuse, I suggest trying the "headlamp" first since it takes a hell of a beating, going down the road, please let me know if this got ya setor not, god bless, and safe riding

The value is probably $100.00. The bike is worthless if you can't get parts. When was the last time you saw a "Baotian" dealership in the USA? Whoever buys it will likely be highly dissatisfied when they find no one will ( or can ) service the bike.

thats normal there is usually alot of play

dear sharil you havent gave to much info about your heating problem. the most common cause for this prblem would a stuck thermostate,or a bad waterpump. but iwould replace thermostate first. not a big job but just a small warning after replacing thermostate and replacing antifreeze be sure to bleed air from system. a little bleed screw is located near the thermostate housing for this purpose

if you plan to modify your exhaust system you will have to rejet your carbs to compansate. kits are availableat most aftermarket shops.

Behind the left engine cover. The engine must be almost completely removed to change it out.

Hi Todd: Sounds suspiciously like it would be brake fluid. Check to see if it is connected to the rear brake master cylinder. (that's the thing that has a shaft that is connected to the brake pedal) Motorcycles like Grade 4.

There's a black plastic knurled knob under the left side of the gas tank that adjusts idle speed.

fuel comes out of air filters????!! no, definitely wrong

Your clutch is either out of adjustment or it's fried.

CHECK WIRING CONNECTIONS ARE NOT LOOSE .
