I bought the bike at 56,000mi. mostly cross country travels. one day i was riding , It started to hesitate backfire, just barley run at all.
very difficult to get started, eventually got it home keeping high rpms. OK added water treatment for fuel.
took apart.
Findings : conciderable amount of oil in air box, plugs were original and warn out carboned up, Valves were out of spec.
Shimmed valves , changed plugs, cleaned air box, New filters, new oil, shaft oil., rear brake fluid,
flushed. Fuel tank drained , refilled with fresh 93 corn fuel
Bike seemed ok for a couple days. Then I have noticed every time I wash my bike ,
the next couple times I ride it , I seem to get stuttering and hesitation.
Odd thing , usually it occurs at less than half tank of fuel .
I have metered the coils , all 4 ohm out correctly,
All coils have rust showing.
The ECU shows many and multiple codes. I do not know how to remove delete or translate the codes I see on the dash .
My thought is to erase them , start over then take it to a dealer I guess and suffer the reamage for A Diagnosis.
I am at a loss, seems like electrical to me or fuel pressure issue. i can tune any carb bike, but other than my VFR this is my first fuel injected
bike Ive ever had to really work on . Im beginning to dislike this machine . . can anyone give me some advice ? please ?
Also as it warms up it sounds out an odd rythmic clunk in the engine. sounds as if its in the clutch or timing area.
this developed before I shimmed the valves.
I also did not notice which elec plugs on teh coils went where 2 have white tape, 2 do not. white ones fell to the right coil on each cylinder.
Assuming i may have those wrong , is there a difference ? like rotary engine has leading and trailing plugs ??
