The Yamaha Road Star Warrior Forum

for the last few days ive been experiencing a problem with my bike(yet again)

its been flat spotting when i first start to accelorate or when the throttles off and im coasting.

ive checked all the leads from the coils and all seems well. ive checked the plugs ,front one was a bit blacker than normal so used the ecu bump to bring it down a bit.

im wondering if its to do with the coil pick up sensor or the throttle position sensor as some of you may have had experience with this issue. 

The only issue i had before i had the two mods done was when turning left or right of a road as you went to accerate the engine cut out dead, natural reaction was to dump the clutch to restart the engine and nearly shat me self cos it just locked up the back wheel and caused it to skid. Since having the mods this has never happened again

i may have discovered the problem. a week ago i took off my switches and taken the covers off to powder coat them at work.

it seems i didnt put the clutch position sensor that is bolted to the clutch lever on correctly.

so far it seems to have done the trick

Glad you got it sorted, see you at the SCR.
