R6 hesitation when starting out

Hello as it says heres, the problem.
the bike is a 2000 r6 with 34 000kms(not miles)
when i purchased the bike there was a known hesitation on gthe bike when you start out in gear
So far the carbs have been cleaned and sync'd, and the cdi box was changed along with the tps sensor.
the yamaha dealer is stumped and so am i
when the bike is at a complete stop 9 times outta 10 it will hesitate and not go over 2000 rpms and 8 kmph, as well you have to keep the throttle half cranked to keep the bike from stalling out.
afterwards with feathering the throttle and clutch it will return to full power. does anyone have any ideas on what it might be
aswell when i come to a stop sometimes the bike idles at 3 0000rpm and have to engage the clutch to bump it down to 1500rpm
mods on the bike are k&n filter and yosh r3 exhaust and jet kit
please advise thanks again
corey

Not often i see good questions like this. I would start with riching the carbs a bit. Another possible simple solution is to get your plugs check to make sure they are firing at full capacity, either one can cause the problems you have described. My first guess though would be the carbs, it sounds like the throttle is set a bit off to what it should be at. The fact that your bike runs fine otherwise also suggests this conclusion.

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. 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 sensor.
9. Intake air leak.
10. Water, dirt, or rust in the fuel system, carburetor and/or filter.

Buell Blast 2000 -problem starting the bike -


That's NOT A KNOWN PROBLEM. He unloaded HIS PROBLEM ON YOU. The best I can figure is that the engine is looking for a ELECTRICAL GROUND and finding one through the cluch cable(only reason it gets hot). Check the battery terminals and cables. Make sure they are clean and TIGHT. Check the engine mount on the front of the motor near the neck of the bike and make sure NONE of the bolts are stripped or vibrated loose or missing. Check to see if there is a ground cable/strap that comes off of the frame and goes to the motor too. Look under the gastank for that one.

2000 yamaha r6. has trouble starting, day or night. usually takes between 7 or 10 tries. also rode it for 12 miles on the freeway. got home turned it off to open the gate. then wouldn't start back up.


Sounds like your pilot circuits on your carbs are dirty. Buy a can of "SeaFoam" pour 1/2 of the can in to a full tank of gas, use the 1/2 on the next tank of gas. This stuff works good and will clean the entire fuel system, valves & combustion chambers. Replace your spark plugs with a new set of ngk cr10ek gapped at .0255. Check your charging system and rectifier to insure proper voltage. Clean terminals and inspect wirining harness and connectors for any corrision. Make sure your air filter is clean. Check for vacuum leaks around carb mounts & cylinder head...This will usually take care of the hard starting conditions on the R6. I hope this helps...good luck with your bike.

Transmission fluid changes/flushes can be a tricky thing, when they replace the fluid, sometimes it releases some buildup and can cause improper function and undesired operation. Call the shop that performed the service and see what they recommend.

these bikes have a lot of carb issues suggest replacing the jets and taking it somewhere to get a new tune, try ivans jet kit . you are still having carb issues it seems like also make sure your whole charging system is working correctly, i.e. rectifier, stator fuses simple things like your oil level can also effect performance
