Battery Box Cut-out for JCL MP250A By we350z (Read 1,359 times)

[we350z]

I hear about people cutting out the battery box bottom of the plastic seat frame so they don't need to remove the plastics to do the carb valve adjustment job. Is there a write-up on this somewhere? Or could someone please explain? How does the battery get held in place without falling through the floor after this? Another thing I would like to do before putting my scoot back together as I would imagine it's much easier to do it now.

--Thanks

You use an extension on the socket to loosen the valve cover bolts, and then a telescopic magnet to capture the bolts so they don't drop into the engins compartment.

I just bored the two holes to reach in with a swivel socket, and then once the cover is off, you can get your hands in to adjust the valves though the big opening.

Question - as I am preparing to do this right now. Do I need to do anything other than cut the rectangular hole in the battery box? You mentioned boring holes? Which ones?? Where?

Pick a spot above the valve cover bolts and cut a hole big enough to stick a scocket on an extension down onto the bolt.
One on the left, and one on the right.

Or cut the middle out of the battery compartment. You'll need a swivel on the socket.

So it's an either or. I just don't get how you could do the job without cutting out the middle of the battery compartment.

Don't you need to reach your hand down there to use the valve measuring tool and to loosen/tighten the valve to the right spec with a box wrench? How on earth could you do that with only the two holes cutout for the socket extension?

Confused....

Have you taken the battery cover off yet? Two screws hold it on at the rear. Lift and separate, cross over to a better figure.

See the carb? All those hoses? The valve cover? Radiator cap?

Wiith the valve cover off, you can get your feeler guage and your wrenches in from the rear. You prolly won't even need to adjust it, just check to make sure it's at .004 with the feeler guage. If it goes in the gap, and don't flop around, yer in like Flynn.

You're gonna love the exhaust valve, when you're upside down. That's the one that will be closed up.

In from rear of what? The big pre-cut hole there? Doesn't the sundries box go there tho? Do I still need to remove that along with the seat but NOT the plastics?

Here is what I have done:

Aw MAN! We need a vid of this one. A Step by Step or even Pics would do.....Hello YOU TUBE Not really, I think I've got the Idea now, but the rest would be great.

Yeah, you go through the square opening in the center, but now you pulled the whole sheboing off, and yer scooter's engine is sittin' there topless.

Get that wrench or socket on the two bolts on the valve cover and open it up. The cover is kinda tight aginst the frame, but once it's off there's another 2 inches of clearance. You can get in there as long as your not wearing a catcher's mitt.

Check the vale clearance, come on, check it.

Oh, and if you do the exhaust, look out for a big splooge of oil to come out when you open the cover, if it gets in your mouth, just spit it out and rinse with beer.
