Gearbox problem, start from the left or right?

[Timmay]

I have a honda CBX250rs which has developed a gurgling gears noise when being started by the starter motor. I have taken the starter motor and checked it and it is fine but the cog it drives within the gearbox can be wiggled back and forth. To get to this gear do i start taking the box apart from the left or right hand side of the bike? eg left(chain and gear selector side) or right(rear brake side)

Thanks to all who reply

TIIIMMMMMMAAAAAAYYYYYYY

Pull the stator cover off (the left hand cover) and the starter idler gear will be inside there.

The transmission doesn't have to come apart at all.

No, the problem is not inside the starter motor, it is inside the transmission. Removing the stator cover reveals the stator, not the idler.

My god, you're right!

Yet another reason why people have always said that motor was the biggest piece of shit Honda ever came out with.

30hp from a single cylinder 250, "piece of shit"...ummm...ok then.

The CBX250RS has radial valves?

I didn't know that.

That's totally cool.

Figures that motorcycle manufacturers quote and reality are often two totally different things.

The CB250RS was a great bike.

The CBX250RS wasn't.

To answer my own question one must start dismantling from the right hand side (rear brake side).

Once one removes the side of the gearbox he is greeted by an idler bearing, ground to bits in the bottom of the sump. Good luck finding a replacement on Sunday. Off to Honda tomorrow then...

why go to honda for the bearing?
Look for the local SKF agent, take the outer bearing shell, which will have a number on it , to them . They should be able to supply a replacement at less cost that the honda OME part.
I get all my bearings and seals fro SKF, they can be up to %50 cheaper than the OME part, and normally have them in stock>
Instead of the "oh thats obloslete", or the " that will have to come from japan" statement parts department love saying . You will get " not a problem sir, we have that is stock, how many do you need? "

which is why honda have a nasty habit of making bearings in 1/2 mm increments....

on further inspection there are gear teeth in the sump oil... a new gear is needed. Does anyone know how to get the clutch apart on this engine, it is the same rcfv engine as the xl and xr. The nut that holds the clutch on is unbelievably tight.

The CBX250RS wasn't.

What's the difference, and in what way is the CBX250RS inferior?

Very different motors.

Those nuts are always uber-tight. You'lkl probably need a rattlegun

Very different motors.

And the inferiority relates to...?

As far as I can tell from 7.3 seconds of extensive innuhneh research, the 'X' engine makes MOAR POWAH.

While it almost inevitably implies additional complexity and/or fragility, is not MOAR POWAH a good thing?
