Question about 2000 Yamaha YZF-R6

Yzf R6 2000 on W reg Runs Rough Low RPM

Hi guys, im finding it hard to get clarification about this, I bought an R6 6 months ago, was off the road a while before i had it. 2 main problems, oil level light always on even changed the sensor, still the same! Other problem is that it misses at low revs and if you are coming down the gears from speed it backfires, although it sounds good its not supposed to be doing it! Its completely standard. Am i right in thinking the carbs need balancing? Everything else with the bike is perfect no loss of power at all. Many thanks in advance Darryl

Hi, Darryl 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. Spark plugs in bad condition or partially fouled.
4. Spark plug cables in bad condition and leaking check for spark leakage in the dark
5. Spark plug gap too close or too wide.
6. Faulty ignition coil, module, and or sensor.
7. Loose, dirty, or corroded ignition module connector at crankcase.
8. Faulty CKP or CMP, MAP, ETS, ATS, TPS, O2 sensor.
9. Intake air leak.
10. Water, dirt, or rust in the fuel system, carburetor and/or filter.
11. Old dead or bad fuel.
12. Fuel tank vent system plugged or carburetor vent line closed off.
13. Vacuum line from intake manifold to fuel valve is broken, cracked, pinched, or missing.
14. Carburetor controls misadjusted.
15. Damaged carburetor.

SOURCE: Find a rebuild kit for 2000 Yamaha YZF R6

your best bet it to order back threw the dealer, but they should offer some kits for the bike threw after-market company's like partsunlimited, lp "lockhart Phillips", and maybe tucker rocky street, at a better price but you may have to buy some parts extra it may not come in a complete kit like the factory offers.

SOURCE: My 2005 yzf 600rt will not idle and is backfiring.

well unless you know how to its best to leave them be if you strip the carbs you will need a tool to set them back up again plus if you take out any jets or screws that adjust the fule mix you will never get it running right again without the right tools to set it back up and a jet can be wrecked by bad cleaning
its your bike? but if you have the cash drop it into a shop for a good tune up

94 nissan pathfinder voltage to battery issue


run the fault codes and check for injector problems
batteries have no set life ( that is what the warranty is for--- new batteries regularly fail at the end of the assembly line ) so if could be failing
have a load test on the battery
Have an accredited auto electrician check the output of the alternator to check it and the voltage regulator
low battery voltage will upset the ECM program

I have 2002 audit quattro TT with 180k miles. When I do a normal acceleration the car surges and rpm drop but pick back up. If I accel hard it runs fine. Also at idle at times it varies 200 rpm like a


this sounds similar to a problem i had. as the rpm went over 2000 the engine would stop for a split second and then kick back in.
after a few days looking my garage finally found the problem was a faulty air mass meter.
this cost me £200 in total to be repaired.

76 volvo 240 car idles and low speed is rough,


It could be the filter. Has the fuel been changed after storage? I would also thing the Carburetor or the fuel injectors might need to be cleaned.
