WHY_NOT???

ok well yeah i cleaned the carbs and now its geting great fuel and runs gr8 as of last night. had to push start it once though


this morning get up to see if it will start cold and nada so i take the tank and airbox off and look at inside the carbs and their spraying so im getting fuel finally

so then i check the spark and nothings there any ideas?

i forget what it is called but it starts with an R and it contols the spark/charge. it is a common problem with the early cbr's

rectifiier?? sp?? i know that isnt right

RubberBerner

Regulator/rectifier, i've heard it called both, and yea thats most likely it, seeing as how its an F2.

WHY_NOT???

so the rectifier controls the spark? wow i thought it woulda just been the charge lol

cuz i know the bike has a charging problem cuz it kills the battery after 10 minutes of running time


gosh i feel like a jackass lol, i mean hey cleaning the carbs im sure was still a help none the less

i feel better now that someone seems like they agree about something lol

and seriously thats a 160 ish dollar part so i feel better about buying that now

i found a good page to help give me some info on the R/R

thanks guys i'll see if this works

Oh, sorry i wasn't aware of your charging problem also. The place you have to start is hook a multi-meter up to find the output of your generator...and if that is good, the only thing that would limit it after that would be high resistance in wires, bad plugs, a bad rectifier, etc.
Basically start at the source and work back...nothing worse than getting stuck with a $160 part that you didn't need

sl2racer

yea that is the part i am talking about regulator/rectifer.

it is responsable for contoling the charge from the "alternator" which inturns supply's the power to the coils and allows for the spark plugs to fire. this is a common problem with that bike.

hey i got that cdi... o ya and a rectifier changes ac current to dc current thats all it does... just start from the source (batt) with a meter and move down the line till you find the problem
