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.

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.

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

Turn lights on complete display goes out


Not quite sure about your light problem, but sound like you might have something mis-wired from the ignition switch check the cannon plug for any bent or shorted pins, as far as the hesitation since the bike hasnt been used in awhile im sure the carbs/fuel injectors are all varnished up, you need to purchase some Sea Foam @ Autozone $10 pour in 1/3 can to 2 gallons fuel and replace or clean out your fuel filter if that hasnt been done, now ride it on an open highway for about 10 to15 miles and that stuff should clean it up and even return any lost hp.

R6 huge bog


Check the TPS to be sure but it sounds more like fuel supply problem when it is cold.Check the chock valves in the carbs.When it kicks in if you close the throttle does it do it again or it does not do it at all after those 5-10 min?
