Re: cbr rrw spluttery

A few ideas from my own RR-W experiences - I ran mine for 6 yrs and 42,000 miles and never went to a garage with it, so have had a bit of experience!

Assuming its got carbs, which I guess it would, I'd
* water in fuel
* some other much partly blocking a jet int he carbs
* kinked fuel pipe
* dodgy vacuum tap in the tank
* and lastly, real odd one that had me fooled... if you've had the tank and/or air box off beware of this. On the RH side there is a breather from the carbs that vents the float bowls and its easy to kink this putting everything back together, of course when you take everything off to find the problem it unkinks so you never see it! The kink creates a ploblem that stop the bike revving out, but only noticable under load when riding, seems to rev ok in teh workshop.

Best of luck!

hi thanks for that but all those are fine you can ride it hard and its ok.
just seems to be when you hold the throttle in any possition eg 1/3 1/2
it also wont respond very well if you snap it open .what does the throttle sensor do ?i unpluged it and it made no difference at all?????????

Have had all the float bowls off yet? You could have a gunked jet or a bent float level tab.

The throttle position sensor (TPS) tells the engine if there is a load on the engine, or if there is a changing load (change in throttle position). The bike can run on pressure and engine speed alone, but won't rev well, and may be unstable at constant settings. Me thinks this might be the culprit.

The TPS is basically a rheostat (changing resistance with position), you should be able to use an ohm meter to see if it changes with position. Also check that electricity is accually getting there and it is grounded well.

Good luck.

Even the internal ones? I kept the ones on either end, which I thought would do just quote what I did .... is the automatic system catching me?


EDIT: Oops, thought you were talking to me ... mine were coming out like demolition's last week, but seem to be working now.

Re: cbr rrw spluttery

the float level tabs on the carb floats were not adjustable on mine, the fuel needle valve acting direct on to the plastic float.

shite in the fuel went straight through the Honda fuel filter causing running problems a few time.

if it were plug leads I'd expect it under load situation, but might be worth a shot with new caps if all else fails??
