Agility 50 / Re: Who cut my cdi?
« on: April 23, 2012, 06:33:07 PM »
Thanks streido/baddy.

have ordered some 6.6g roller (couldn't find 6.5) so will see how I do with that.
One typo in my last post - I'm NOW (not "not") revving higher earlier with no increase in acceleration.

Oil filter is clean. Oil level is correct (0.7l on refill)

Could worn clutch plates be doing this? It's only done 7000km.

I figure it's either worn clutch plates or poor compression. It seems to burn through oil quite quickly and I may have let it run dry as a consequence on one occasion....

thanks baddi
I was trying to flush out the problem this weekend so put in brand new rollers (6g) and brand new good quality belt.
No improvement. In fact I guess stock must be 6.5g as I'm now revving higher earlier with no additional acceleration/power.

carb adjustment...i have an #82 jet, but must admit have never adjusted the float height. Didn't really understand the physics behind it but maybe should check.

Battery is new and fully charged, and spark plug is new, plus  I replaced the ht lead less than 6 months ago so I don't think ignition is the problem.

That said every time I change the spark plug it is black black black, covered in carbon which is interesting. I change it nearly once every 2 months!

Thanks zombie
I've had that carb apart more times than I care to mention - it's clean as a whistle in there.

thanks whitenight.
yes i think you're right there does seem to be a cut line amongst the epoxy. will go check on the thing itself. I do get 40mph out of it (on the speedo at least) so I think the cut has been done correctly. I just have poor acceleration.

i have a derestricted drive boss.

valve clearance is normal.

I think compression might be the problem.  i have a compression tester but annoyingly it wont fit in the hole in the agility due to constrained space.

incidentally idle mixture screw seems to have no effect however it's turned and the thing loves to idle low and cut out. Idon't know if that is symptomatic of a general fuel line problem which might be causing my generally poor power (in particular acceleration)

thanks guys. blue it works fine, i'm just trying to work out if it has been cut or not - can anyone answer for sure?

I still have very average performance on my scoot so I'm just trying to identify the cause. But from what wordslinger has said (thanks wordslinger), it's unlikely to be my cdi that is the problem.

Back to randomly replacing everything I guess....

Hi folks

Can anyone tell me if the below is a CDI that has been cut, or not?

Also is it possible that an incorrectly cut CDI can result in a slight loss of power

thanks streido. there's definitely something up with my scoot.
Will try the mixed rollers and see how i get on.
Then I think it's either the garage or the bin.

I tried 5.5g roller weights in mine and they did just the same ened up with 6g by mixing three 5.5 with 3 of my original 6g after Sterido gave me the tip  ;D

Unrestricted you should see around 42mph CDi on mine is deffo de-restricted, AG50 is a nippy rather than fast bike but I find climate makes a big difference to performance. Cold or wet days and power is down slightly, last week especially the bike felt a bit sluggish at times.

Interesting jezyg. I do get about 41mpg top (on the speedo anyway). It's my acceleration that is a bit embarrassing. I'll try mixing the roller weights and see how I get on.

Thanks Streido and others, and sorry for sort of hijacking the thread.
I did fit 5.5g rollers a while ago but the thing just revved super high really early and performance was poor.
I was having all sorts of other problems back then so maybe I'll try again to see if there's any improvement.

Don't think it's still restricted - the boss and the #82 jet are defo there. The CDI is original I think, and I can't see any obvious cutting, but then I'm told the 2010 agility doesn't have a restrictec cdi, but some disagree.

I'd really prefer to have a restricted bike but the last owner derestricted and didn't tell me. Just trying to get a feel for if the bike is naturally quite slow or not.

Thanks

Guys I'm trying to work out if my 2010 Agility is faulty or normal.
My acceleration (#82 jet, smooth boss, no other changes) feel p*ss poor. I make 0-30 on my speedo about 15 seconds. I am always the slowest of all the other scooters (london - mainly vespas or similar) off of the lights and never really seem to catch up.

Is that normal? Or has everyone else got 125cc bikes? I weight about 97kg if that might be making a difference.

Any ideas? Is the Agility 50 generally quite slow, or does my bike have a problem?

Any thoughts welcome.

yeah. I get the feeling the new battery has helped.
It seems to be starting ok-ish now as well.
I think i've squashed the carb gasket as it was ill-fitting and now it stinks of petrol all the time. Probably leaking a little so have bought some instant gasket to seal it up when I get the chance.

Other than that seems to be more or less there.

Don't suppose there's any other known causes of petrol smell?

Ok then, a Christmas update.

This seems to be a carb problem.

I took the carb apart, blasted some compressed air around it (again) and put it back together again. In reality, I don't think it was blocked in any way, but did it for good measure.

After that, it seems to be working ok again now.

Then I rode it 45 miles twice (visit to parents) and now it seems to be running ok, if a little hard to start. In fact, it's now running faster than ever.

I'm sure it will fail again - at the very least I don't think the carb is property tuned - but at least I know it has something to with the carb in one way or another.

Thanks everyone for your help with this. I seem at the moment to have got there.

changed the battery today. No difference.
That was an expensive test.

Thanks, guys. This bike has been a headache since I got it. Sidthesloth - I don't know whether the lights come off the battery or the stator, but I would guess the latter.

on the plus side I figured out how it was derestricted (variator boss), but in terms of running, if it's not one thing it seems to be another...

Here's what's happened the last two times I've used it:

Runs fine in the morning full power UNTIL my first stall of the day (normally at a traffic light). After restarting using the kick OR the electric starter, the power has gone and it stays at low power.

I know I can get round the above stalling by adjusting my idle, but I'd still like to get to the bottom of the problem. New battery is going in tonight but this is mainly a short in the dark. So the question is...

What happens when a bike stalls that might create a "low power" condition immediately afterwards?

ok. developments...

Found a loose bolt on my crankcase last night, though can't remember which bolt it was. May have been the refill bolt, may have just been a bolt to hold it together.

Either way I replaced my transmission oil last night. This morning on the bike, I had 5 miles low power first, then 3 miles good power (if a little poor at low speed), all on the same journey.

So, may have been transmission oil, but still suspect my battery - my lights dim and flicker pretty seriously when the bike is idling. If not the battery, and not the coil (recently replaced), I guess this may be some other electrical issue. Will get the manual out.
