Fitted a open cone filter today

Also upped my jet from 82 to 88. Started it up on the stand and revved it, it died down on revs when i tried to WOT and started kind of pulsing up and down the revs when i tried to hold it on throttle open.

Took some tape and sealed up about half the filter and tried agaim on the stand. It was better but didnt feel quite right. Went for a quick ride and it felt a bit lumpy or boggy when i opened up the throttle past half way. Stopped halfway and took a little tape off to let more air in, that made it worse. Got home and this time i taped up about 2/3 - 3/4 of the open filter and tried it on the stand, that felt pretty good so i went for a ride again. This time it was a lot better and almost felt as good as before i started messing with the stock filter.

So my question is do i just need to go even bigger on the jet? If im on a 88 now and only using 1/4-1/3 of the air filter how large do i need to go do you think so i can ride without tape on the cone? Im thinking at least 100 jet or 110-120 even? Does this sound about right?

Dont want to wreck my engine running lean so any help or advice would be good? I know Wordslinger usually ran 101 or 110 i think on his open filter so im guessing thats my problem, am i just using too small a jet? Checked my plug after my last run again and it looked ok, light tan,on the boggy runs before it was very light tan almost going white.

Ok. I was getting good top speed, best of about 48mph on the speedo downhill, then it dropped off a bit gradually over a few weeks till i struggled to get to 45mph, usually got about 43-44. I checked my belt which was the stock original and it looked a bit worn after 13,000km so i reppaced it with another Nakura belt the stock size and i got my topend back again. All was fine for a month or so then it dropped off again. I checked the new belt and it was fast becoming toast, the top surface at edges had come off on a couple of areas, so i stuck my old worn belt back in till i got a new one ordered.

New belt is a Malossi kevlar, 736-17.5-30, longer than stock which i wanted to try out. Took it out and i got it off the gauge downhill so i was well chuffed, 52mph showing on the speedo, 1st time i had ever got it off the gauge, i was over the moon. Been running good for 2-3months now but again i noticed i had gradually lost too end till today i went on my test route where i hit 52 and i only reached 45-47? So i had def lost about 5mph. Stripped down the variator and belt and all looked ok. Only thing i noticed was the boss and variator mayne felt a little "sticky" and not as free moving as i would hope. Cleaned it all up and put a very small amount of lubricant on the inside of the boss where it goes round the crank. Went out and my top end was 49- 50 again, a good 4-5mph up on earlier.

This leads me to believe either my boss needs replaced or i need a new variator, anyone agree or disagree?

Since all i did was clean up my old variator and boss and that restored most of my top end i guess the surface of the boss is maybe worn and not as smooth as it should be? or the hole in the variator is worn and unsmooth? I think if i could get some lubricant in there that would stay there and not spin out over my cvt it would be fine but what can i use that will last and not burn off or spray out? As far as i onow you dont usually ever grease the variator or boss so maybe i just need a nice shiney new one?

Just to say also, when i lost top end it would get to 43-44mph then it felt like it was being held back or starved of fuel or air a little, after i lubricated it this went away and my topend returned. Same thing when i replaced my belt, but i wouldve cleaned it all up then too so i think the belt was not the issue, it was the variator or boss or both. I figure the variator is moving in on the boss as i get faster until it gets to 80-90% then its sticking on the boss and not sliding all the way in as it should. Obviously when i clean it up and lubricate it then it helps the variator slide again on the boss and its going all the way over at top speed, so the problem must be with the sliding motion of the variator, right?

LMAO, mental. Wish my 50 would do this 

How good is your back brake? I am asking as i noticed last week that mine is pretty poor really. I know its a drum so wont be as good as the front disc but i is really pretty rubbish when used alone.

I checked my pads/shoes and they are fine, checked the adjustment and its set correct, i have very little play on the lever but still it seems to take an age to stop if i use just the rear and leave the front alone.

I wont not use the front brake normally but by chance i somehow i noticed last week just how poor the rear was so wondered if it was normal?

How is everyone elses rear brake? If i get to 20-30mph and try stop using only the rear it takes a long time, well over dounle the distance of my front brake i reckon. I maybe just never noticed it before as i use both brakes normally so it was maybe always like this?

Was uploading some stuff and thought i may as well put these manuals up in case anyone new needs them. You can download them all for free if you do need or want them on this file host site i used.
Hope someone finds them useful.

Dont know how long they stay up but if a link is broken just let me know and i will put it back up again.

Finally got round to uploading some pics of my new mirrors and visor that i fitted a few weeks ago. The mirrors were less than £10 off ebay from china and are pretty good quality. The difference is amazing, i can actually see behind me now without twisting my body out the way 1st 

The visor was from a bike breakers yard and was £7.50. Think it was originally off a Peugeot scooter but after a bit of cutting and filing i fits my Agility almost like it was meant for it. Im happy with how it looks now, what do you all think? Does it look ok? Its not really to deflect wind, its more just for cosmetics.If it cuts the wind a little all the better, i wont complain. Still got to repaint over the fixings black again cos the silver is showing thro a little after one coat.

Riding to work this morning i stopped at a junction. The car behind stopped too then decided to just pull onto he road without waiting for me to get out the way. I have no idea what the woman was thinking, she def wasnt looking ahead anyway. I was stationary, she ran into me at a slow speed but pushed the scoot away from me and it fell over.

Im fine, didnt even fall over. Scooter had bust number plate, clip where the rear mudguard clips onto the exhaust has broken, one rear indicator got bust, and a mirror came loose. I cant see any obvious damage anywhere else but wondered if it may have damaged any engine mounts or anyhing else? Is there anything else i should check?

If she wants to pay me cash for repairs i will accept that just to get it fixed quickly but if she starts messing about i will be putting in an insurance claim to her and claiming for whiplash too since i was rear ended.

I need to phone her tonite to find out what she proposes. Just want to make sure i check everything out i need to so i can get a price for parts before tonight.

Thanks.

Anyone have any idea why my idle speed would be fine, 2000rpm, when on the centre stand, when I put it down off the stand its still fine, then when I sit on the seat it goes up to 3200rpm?

I dont weigh that much, 160lbs 

Dont see any touching of the bottom of the seat compartment and the carb or anything obvious really so ideas welcome.

Going to go have another look now in case I missed something
