UPDATE

i did a few plug chops today with a new plug starting off by removing the K&N air filter and putting the standard airbox back on with an 82 jet, the scoot performed terribly, sluggish slow and cudn't get passed 25 and extremely lean, i then went up in stages all the way back up to 88 which was too rich. i ended up settling with a 86 main jet with the K&N which is running perfect according to plug chops and the way it drives. my tops is still 45mph to 50mph but the acceleration bog isn't as harsh but is still there unfortunately.

i've just measured the bolt that covers the clutch and am i right in assuming i will need a 39mm socket to remove it so i can install the clutch springs and contrast spring.

Now just got to sort that ratlle noise haha

so im probably best warming up on my plug installed now then using a new plug for the tests and starting off with lower (Lean Jets) and moving up until i get the right plug reading.

and im also gonna check my variator is installed correctly and the crankshaft bearings are ok.

i really appreciate the help by the way mate.

do u think the bigger jet and air filter is worth the hassle or should i just put the standard air box back on and put an 82 jet in, will the difference be that much as my friends is standard and his is faster at the moment.

sorry to sound like a moaning kid, im just competative and want mine to be faster haha

ok will do, ill keep you posted on how everything looks, ill try and put like an 84 with the air filter on and also an 92 and do some plug chops asap.
with regards to the rattle, one thing i noticed is when i bought the variator it came with a plastic washer but no instructions on were to put it, i put it on before i put the variator on and everything worked but the scoot was sluggish and only hit 40, i then took it off and i hit 45mph. but both times the rattle was consistant especially during 1-20mph. and still bogging down for 1 or 2 seconds.

scooters are frustrating but rewarding when they work and it doesnt rain haha

I think the rattle is from behind the transmission housing mate, and the fact that the malossi rollers have bald spots from 1 weeks light use is a bit worrying for me 2 be honest. just cant wait to get the scoot dialed in properly so its more consistent. If i have put the dr pulley sliders in the wrong way would the scooter still run and change gear? i got 5.5 gram 16x13. is this correct? and i assumed my standard variator was making the rattle last time when i saw the rollers were flat so i bought the malossi multivar and the noise is still there. 

do u think this could be the cause of the bogging down aswel? or should i still do the main jet change?

Hi there,
This is my first post on any type of forum so please take it easy on me if i miss any details out.

I recently bought a used Kymco Agility 50 4 stroke on a 2009 ( 59 ) plate in the uk and it was fully restricted. The bike Has 8000km on clock and has recently had a service. After reading many of the positive reviews that people had posted after they had de-restricted their scoots I decided to go ahead and do mine.

this is what i have done in order since owning the scoot

i cut the CDI
installed new de-restricted drive boss
K&N free flow air filter
88 main jet
malossi multivar variator
Malossi kevlar x belt
5.5 gram dr pully slider weights

i have purchased clutch springs and also have the white malossi contra spring but im waiting delivery of a socket big enough for my impact wrench so i can remove the nut on the clutch, think its 34 or 33mm.

the scooter drives well and feels smooth once going but is quite slow from a start and when i rev it tends to bog down for a second or two and then picks up. my top speed is roughly 45mph shown on the clock but i highly doubt the speedo is accurate, feels more like 40mph tops.

My aim is to get rid of the bogging and get a quicker acceleration but maintain the same top speed.

Am i right in thinking the main jet might be too lean or too rich? its hard to get parts for the agility here in the uk but i managed to get a naraku main jet kit which has sizes from 80-98. could you recommend if any of these?
im also  thinking of putting the standard air box back on and putting a 84 main jet in as a friend has same scooter but with only new belt, drive boss and cdi cut and his is way faster of the mark and same top end.
 On a side note i have also noticed that my rollers are getting flat spots alot, i put 6 gramm malossi ones in before the dr pulley and after only 1 week i had very noticable flat spots and when driving i hear a contant rattle, sometimes even whilst the scooter is idle. Any Ideas?

sorry about the long post and any help is appreciated.

regards paul
