RGV250 rebuild?

The battery is shit, thats seems like a good theory, thanks

They always run like shit with a bung battery. Seen peoe chase phantom rgv issues for ages to find that it was a simple low voltage prob.

Yes, a healthy battery is mandatory on RGVs and RS'.

Shes a beauty.

Rode to Akaroa today and the bike was still playing up. It would fart around at revs below 8k then take off.
I replaced the battery and tried another sapc but it hasnt seemed to do anything.
I will try another CDI unit and give the carbs a clean.

I also managed to loose my pillion seat somewhere on the way back from Akaroa, anyone have a spare?

- Which pipes?

The 280/270 jets are probably fine, but there's a few odd carb models so you want to be double checking that stuff at the very least.

If you have no luck with carb clean and cdi swap then it's time to go back a few steps as farting around under 8 thou is too vague a description to go off.
It got you to Akaroa so unless you were redlining it all the way was she able to pull through these revs at quarter,half,full throttle?or was there just a bloody great hole in the power before the PV's opened up? (Thats if they are opening/fully closing...it always pays to check again)
These bikes don't make much below 7000 revs anyway and aftermarket pipes can make them worse on the road.

So if need be post up as per imdying questions above.

Well accelerating and cruising through the first 4 gears it would stutter a bit before it hits full power and turns into a rocket but for 5 and 6th unless i was in power band i wasnt going anywhere (it was easier to cruise at 100km in 4th than in 6th

)

Ive tried using 22D00 and 22D20
34mm carbs
Not too sure what jets i have in them.
The air solenoids are plumbed up correctly (i think). What symptoms would i have if they werent?
Stock air box
No idea what pipes they are, they arent stock but they have no stamps to say what they are.

No idea of pipes and jetting? now we're getting somewhere.Any RGV will struggle to pull 5th and 6th under 7000 anyway so not too much of a drama.
Do you have a manual?You do really want to know what main jets you are running in both carbs as a starter.
Have you done a plug chop? This will tell you if the main jets are generally the right size.
However next point of reference after this should be the jet needle and in particular the clip position.Standard is in the middle (3rd) position of five.
As an experiment raise the clip to the top of the needle and take her out for a ride and see if it is an improvement.Lowering the needle/raising the clip has the effect of leaning out the mixture in the quarter to half open throttle settings.

For now dont worry about the diff SAPC's and air solenoids as only dyno dave types can tell the difference.
Oh yeah do you have a manual???

22D00 is a Jap SAPC with the low/mid raped out of it. Bin it.. it's designed for a 32mm carb and a mighty 45PS at the crank.
22D20 is another Jap SAPC, 45PS at the crank again.

Most RGV owners have one... or two... or in some cases a box of them! Now you know why

You want a 22D30, or a 23D70 (Aprilia RS250), or ideally a Zeeltronic box. Everything else is either a race unit (boom goes your engine) or some other restricted fucked up shit... see below...
