Just some feedback on this problem. I checked the fuel which was OK and the airfilter also ok and then checked the spark plugs one of them showed heavy deposit of carbon.. The plug was not very well seated either. After I returned the plugs (properly seated) the bike started but kept on missfiring. I changed the plugs and the problem resolved . First attempt start and running smoothly. Thought you might like to know the outcome (defective plug and caused by poorly seated plug causing it to get looser over the time. Thank you very much

Hi what spark plugs for a Yamaha 400 dragstar. thanks

I would definitely go with an iridium plug offered by NGK for the most complete combustion which increases engine efficiency, fuel efficiency, and power. The part number for an NGK iridium spark plug for a Yamaha dragstar is DPR7EIX-9. These are a bit more expensive at around $7 but are absolutely worth spending the extra money as they are proven to last significantly longer. If cost is a factor, a regular ngk spark plug is around $2 and would be part # DPR7EA-9. I hope I've answered your question satisfactorily and ask for you to take a moment to rate my answer. Thank you, Jim. NGK 7803 DPR7EIX 9 Iridium IX Spark Plug Pack of 1

Yamaha XVS 1100 Dragstar

Hi, Anonymous and the usual suspects are:
1. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
2. 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.
3. Faulty main circuit breaker and or connections.
4. Faulty ignition coil and or connections.
5. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator.
6. Faulty spark plug cables, leaking or broken, internal damage check for spark leakage in the dark.
7. Faulty ignition module, switch, CKP, MAP, CMP, sensor and or any connector in the ignition circuit could have corroded, loose, or broken pins/sockets
8. Burnt exhaust valve or air leak in the exhaust system.

My yamaha atv grizzly 700 will not start in very cold tempereratures

hi , solution is very easy : change the spark plugs to a "Hotter" plug . there is a difference in heat generated by spark plugs but you need to be very careful by not going too hot as it could burn the piston . Make sure you ask your bike dealer prior to fit any spark plug in your bike . This should solve your problem .

My yamaha 400 dragstar will start easily and run on choke, but as soon as the throttle is touched the engine cuts out, will not start on throttle only on choke.

That's a fuelling problem
Sounds like she has been laid up for a while -
If more than 5 or6 months then you'll have to drain & replace the fuel from both the tank & carbs
If over a year then you may need to strip the carbs

It could just be sticky floats - try adding a carb cleaner to your fuel

Gets no spark and ive replaced the plugs wires ignitor and the pick-up and still no spark

Are you starting with aa charged battery? Are you starting with an electric starter or does this bike have a kick starter? Did you measure if you have any voltage coming out of your generator?

02 Yamaha xvs 650 dragstar classic that misfires when it warms up

First I would change all the spark plugs, and if that didn't make a difference then it sounds like the coil(s) are warming up and breaking down........when it starts to skip take a good pair of pliers with good rubber on them and pull each spark plug wire, when you get to the one that the running doesn't change then I would replace that particular coil

I just get a cliking noise from the starter relay when i start the bike up

Hi and welcome to FixYa,

A couple of ideas to consider:
  • if there is a clicking sound, follow the battery cable from the battery's + terminal;
  • it would end in 1 of the terminals of the starter relay;
  • while pushing on the start button, short the 2 big terminals of the starter relay on the nuts (not on the threaded portion);
  • expect a big spark;
  • if the starter motor spins when shorting the 2 terminals, the starter relay is faulty;
  • if no spin, then the starter motor is faulty, most likely the carbon brushes.
Should the above be not applicable yo your concern, please postback results.

Goodluck and thank you for asking FixYa.

XVS1100 Dragstar, blue color of hrom pipes outer of cylindar 2.

Hi .... This is a common occurence, esp'ly with aftermarket pipes, where they are made from a single 'skin'. You can buy a special cream/polish solely to remove the discolouring. Make sure both spark plugs are a light tan colour which shows the mixture is OK. An old british bike trick was to wrap thick copper wire along the down pipe to disapate the heat.
