SOURCE: Kawasaki Vulcan 1500 (not FI) funky sound after shut down

Hi, Yes it is an electric fuel pump and the ticking is the pump working. So if you hear the ticking your pump should be OK. After turning off the petcock and running the carbs dry the next time you turn it back on you should leave the kill switch on and turn the key on and wait till the ticking stops, turn the key off and back on and wait for the ticking to stop again. You should do this a couple of times to make sure the system fills. Normally you should always use your kill switch to turn off your engine. Also under normal conditions you will not hear the ticking as it only ticks a couple of times to fill the system once it is full. Good Luck to you, This should Fixya!

SOURCE: 2003 vulcan 750-how/where to check engine oil level / noisy

there should be a little window just below the oil fill area that says high and low, that's where you gauge the level of oil you have. it's not a dipstick, and not very precise, but that's it.

1. I have an 02 and just normal riding temp for me is 170-188. 2. Yes that is possible you can get a toggle switch from any auto part store and rewire the fan so you can turn it on when you want. Thats what I did and I turn mine on around 175 just to be safe. 3.Yes you would be able to see it through the oil window.

Hello i have bought new tyres and the rear tyre is a different profile it should be an 130 /80 /17 and the rear tyre arrived as a 130/90 /17. Will the 90 be ok on the bike thanks for your reply

Hi, Caroline the 90 should be ok it is a taller profile which may affect your speedometer accuracy by 10% it will also decrease your cruising RPM slightly which adds longevity to your engine life. Depending on the year-make-model of your bike the speedometer may be recalibrated to compensate the difference..
For this situation, I would call or visit my local dealer or reputable shop's service/parts department and inquire about any possible quick fix, answers, or parts inquiry.

Bike wont start

Hi, Anonymous and the usual suspects are:
1. Fuel tank empty.
2. Fuel supply valve/petcock turned off.
3. Fouled spark plugs.
4. Engine flooded as a result of overuse of the enricher.
5. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
6. Fuel valve/petcock or filter clogged.
7. Discharged battery, check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
8. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, cable connections loose, or connected to the wrong cylinders.
10. Ignition timing incorrect due to a faulty ignition coil, ignition module or sensors (MAP, CMP, CKP, O2 and/or BAS).
11. Security alarm needs a reset.

I have made my zzr into a streetfighter and i want to move the thermostat from the side of the bike becaouse it doesnt look right. can i extend the pipes and move it to the back or does it have to be above...

the tank you made is fine that is there as extra. the thermostat problem easy fix, type this into your google search.... koso water temp sensor adapter .... this is a adapter that goes in the water line it's self. simply cut the radiator hose and put in the adapter then screw in the temp sensor and run wires.
Send me some pictures of the bike. I love the smaller bike I'm working on a bandit 400 and a gt 250.
Good luck

1. Frame. If you've owned K-bikes, you know that nothing flexes between the steering head and the swingarm pivot. Very stable. Not so on BMW airheads, with their double-cradle steel tube frames, which earned airheads (like the R90S) the nickname Gummikuh (rubber cow). 2. Brakes. The R90S has 70s-era brakes. Not so good by comparison to late 80s-early 90s K standards. Many of the Ks also have ABS. Not so the R90S. 3. Engine: K-bikes engines are liquid-cooled fuel injected, computer controlled, and exhaust catalyzed. The R90S, like other airheads, is carbureted and air-cooled. Stay out of traffic jams on the highways, or pull over and shut it off. 4. Tires: The post-90 K-R bikes models have radial tires. I've found the R90S, like the KRT/LT models, to feel somewhat tall with its bias ply tires. That said, several years back I bought an R100RS just to own one, and to understand the experience was. Didn't hold a candle to a KRS in terms of performance, but had a certain heritage-appeal.

Increasing the sound

wont realy change the sound at all, would be a waste of money. in my opinion dump the whole exhaust system because it stranles the engine and replace with a de-catted system, you may still be able to use the yoshi end can
