Question about 2006 Yamaha YZF-R6
I thought is might be bad gass so i drained it an got some good gas but i think it might be tha pluges now
Hi, Jreprogle7 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.
16. Incorrect valve timing.
17. Weak or broken valve springs.
18. Damaged intake or exhaust valve.
19. Check for engine trouble codes

I would start with a new start of spark plugs...look closely at the ones you remove and from which cylinder they came out of...Learn to "read" your plugs, you can tell a lot by doing this on what kind of fuel mixture you are getting...a light colored electrode will indicate a lean mixture, a black would mean rich, black and wet, fouled and not firing...ideally they should be a dark brown. The injectors are probably dirty. Buy a can of "seafoam" pour half of it in on a full tank of gas and use the other half on the next tank...it works good to clean the fuel system. Your valves should be checked at 24000 miles....also check your charging system, the EFI on your bike is senstive to low voltage and surrges...you should have 13.5-14.5 vdc at the battery at 2000 rpm.
good luck, i hope this helps.
