Desperately seeking a solution

Evening all,
I am havinf serious problems with my 2000 Peugeot Speedfight 2 100cc. Some of you may have seen my previous post:

I am still having issues, to re-cap whats been done:

new ht lead, carb cleaned, carb needle split pin adjusted from 2 from top to 2 from bottom, also found to be alittle bent so replaced with a11 type, ht lead found to be getting wet (missing guard) mud flap fitted to stop this, exhaust cleaned out.

The bike has finally stopped cuting out, however it has now started to bog down, can be going along quite happily at 55 with no issues, going up-hill open throtlle full nothing there, slow down for an island open throttle full nothing there, still getting the odd back-fire but not as loud now. Slow and steady seems to be fine but with throttle half open pull it further nothing there.

Sat stationary 9 out of 10 times the engine will rev fully, just seems to be riding when it does not like it.

I rely on it to get me back and forth to the lock-up and short of saying feck it and buy something else i refuse to let beat me i am not one for giving up!

Filter seems dry, all jets are clear, reeds seem fine, only thing myself or the garage has not sone is remove the head to look at the piston, but compression is fine. I keep thinking its something do do with the carb slider/needle or fuel stavation i cant seem to think of anything else.

If the clutch/rollers were knacked would this still let the engine rev to full, just no drive?

If the clutch/rollers were knackered then it would bog down to begin with, would be like trying to pull away in a high gear.

It could be that the clutch/belt is slipping under load maybe.

Might be worth removing the clutch cover and using some sand paper to remove the sheen from the drive plates (if there is any that is), or if that doesn't work try replacing the belt.

cheers ill try anything, just seems to be revving fine then when i pull the throttle open ful there is no revs at all goes almost silent till i let the throttle go and start to gently open it again.

[glowwormer]

if the tube from the reed plate to the fuel pump/filter was blocking up what kind of fault would i expect to see or hear?

[andym]

sorry I thought it was a problem with it climbing hills etc.

Have you tried adjusting the needle back again and see if it still does it?

[glowwormer]

No i havent to be honest, its been fine for two weeks now, thats the other odd thing. According to the haynes manual its in the correct position but having said that there is nothing to say its not slipped back to the position i moved it from which would kinda of make sense.

yeah i thought belt as i was on my way to the lockup this morning as it only happened when i was pulling up a hill, but tonight on the way home it litterally seems fine but the throttle dies about half way, almost as if its electrical as it goes really quiet let go thou and straight away ticks over fine. possible immobilizer? but surely that would happen always?

Its almost exactly the same as the first issue a good few weeks back just that it doesnt die completley now just half way through the throttle range.

Almost certain ive found the problem, and ill try to explain. WIth the air box off bike runs perfect, air box on and reving if i cover the air box it dies let go ticks over fine.

Had the air filter out and it is in actual fact wet through, and the box is wet through, with box off it is occasionally spitting fuel, althrough to be fair its more a fine mist rather than lots, but know whats causing it???

Float in carb seems fine, doesnt seem to have any adjustment settings, beleive it to be a dell orto 17.5.

next question is whats wrong and why does this seem to clear itself for a few weeks then give me loads of hassle and then be fine again i am beginning to think its my wife twin lol

[andym]

it could be sticking, give it a couple of taps with the handle of a screwdriver. I had that happen with the last scooter I sorted and the tapping the carb sorted it

[glowwormer]

Well things seem to be ok again (fingers crossed) just seems alittle slugish but this may be to do with me removing the air pipe from box to under seat just to see if i can get a bit more air in.

Not removed the box to check the air filter, will do this tomorrow. tapped the sump as suggested so im hoping your right and its just sticking, small screw driver under the seat just incase!
