I recieved my parts today i ordered a main jet pack 10 jets in all high flow filter and a variator boss,the jets start at 100 then 102 to 120 am i right in persuming these are too big for my agility 50 the ones i ordered started at 80 to 98 i specified my bike on ordering the parts and recieved these does anyone know the main jet size in a 2005 agility 50 four stroke?? as i know the one i require is 3 to 4 sizes higher than the one in there right now.also been browsing thro the service manual and it says engine oil should be 15w 40 i have put in 10w 40 synthetic blend? is this wrong.also lol i recieved a modified variator boss with the same order the dimentions are as follows 20 x 38 x 14 yet the website i ordered from refares to this as a 28mm boss the part number comes back to 28mm but the packet it came in has no referance of 28mm?????? soooooooooooo confused please help me :-\ omfgdotcodotuk
-
sorry forgot to mention the modified variator boss dimentions are in mm milimeters :-[
-
...unless you modify or replace the exhaust, those jets will be too large...
..i would think that around 90-95 would be a good place to start doing plug chops...
..I have used 10w-40 since forever...
..i'll measure a boss, but i do believe it's @ 20mm in outside diameter...
-
cheers slinger yet again your a god send bud.if you could measure the od , id and length off boss that would be great,the jets are so going back tomorrow and i think the filter will be too as the picture shows a clear 30+ degree bend in it and mine is straight so it will sit on top of the engine gathering all that power soaking warm air :o tc bud and thanks again :)
-
Ermmmm slinger modify the exhaust? what can i do to it and will starting from a 100 size jet be ok?????
-
plug chops? sorry im a newbie does this mean cutting the plug or what?.I really dont understand this term?????????????.helpppppppppppppppppp meeeeeeeeeeeeeeee plzzzzzzzzzzzzzzz lol ???
-
Not that questions are ever unwelcome in the forum (I ask all kinds of silly crap) but...
hit all the old posts in the a50 and the how to section.
its a gold mine and has helped me so much.
plug chop is a way to see if you are running lean or rich.
As much as I've read here I still and not entirely sure how to do it properly.
Good luck man, sometimes we think we've ordered the magic part only to see it was a cheap card trick.
-
see glo in that case i need to send back the jet pack as its obviously too big for my bike as i am running standard exhaust >:( i would need to mod my zorst but would not know were to start as its 4t and im used to the 2t config im so confused right now,as all in all im not used to forums too :-[.so its a repost back to supplier for me................
-
Wordslinger has drilled holes in his exhaust and put pics on to show where. I am not sure which thread it was.
-
cheers sid i will try and find this post.ty very much tc bud :)
-
..i cut open and removed the catalytic converter, which i wish i had left in, because it was not restrictive...
..but i did drill these holes in the bottom of my pipe...
..it worked!!
..i'm in NO WAY suggesting that anybody do this!!!
..i'm always modding to the extreme..thinking outside the box...
..see my "blown air induction" threads...lol..
..but getting ready to re-jet to a 103...1.03mm diameter...
-
so lets say lets think out the box here for a mo ;) drilling holes ie 3 to 4 around 4 to 6 mm at the bottom of the pipe will improve the performance and allow me to run a 100 + jet set up bud holes obviously to back / baffled part of system.does this dramaticaly up the sound level of the bike ????
-
..my holes are about 10 mm...
..any time you can increase air-flow through your engine, it will, with the correct jetting perform better....
..up to a certain point...which we will not exceed!...lol..
..it gave my scoot a more throaty sound...
..the air filter will more dramatically increase th volume!!...
..and again...i don't say to anybody...go drill your exhaust...
..except sid...think i told him to once or twice!!..lol..
peace
-
20 x 38 x 14
..that is the correct deminsions for a de-restricted drive boss...
:)
-
thanks very much again slinger your a god send :) tc bud
-
Yeah, told me once or twice, and I still haven't done it yet. One day.
-
lol do it sid and post your results.The kind people at centralscooters are re posting the jets i require next day so i should have them (there words) before 2 pm tomorrow so we should be rocking by the weekend,the filter is a great fit and i now know thanks to Slinger that my variator boss is correct so lets get this show on the road me thinks!!! WEATHER PERMITTING of course ::) tc omfgdotcodotuk
-
Ahh, never mind the weather, just do it.
-
i am a wuss when it comes to rain i admit it sid lmao but we will get there in the end. :)
-
ermm the small bore pipe coming from the head to the airfilter can this just be pulled of an disregarded or what?as i presume its no longer required as the a50 it having a high flow filter,what is its purpose? ???
-
...people at centralscooters are re posting the jets i require...
Are they the correct size?
-
yeah glopez the set contains 80 82 84 86 88 90 92 94 96 98 jets 5mm thread so i recon i got it covered do you? :)
-
do you know the standard jet size in the a50 bud?????
-
I guess its the right size to fit...
The Standard jet size is 88 from what I hear.
Seems like you'll have about half a kit you can't use but the rest should be good.
-
thought so.i also got the 100 to 120 kit if needs be but dont think i will need it as my zorst is bog standard but may not be for long lol :-\
-
4 stroke engine, that sounds like pcv pipe. It should feed back into the inlet. I believe some are just pegging it up out of the way.
-
I think it just catches some of the unburnt gases at the head and sends them back through the air filter, I just plugged it up.
-
do you know the standard jet size in the a50
..oem restricted jet is an 80 or 82...could be either one...
-
god darn id marry you slinger but the problem is i aint that way inclined,(but still love u in a man type way ;))lol wtf u know what i mean!!!,cant realy tell you how much of a help you have been.Please dont feel offended and im sure you wont be,if i bombard you with questions in the near future,if you dont mind.tc :)
-
..omfg...thanx man...
..i like being able to help my brothers and sister of the scoot...
..i've made a bunch of mistakes along the way, and if i can keep somebody from having to go thru some of those, it's all worth the while...
ermm the small bore pipe coming from the head to the airfilter
..that is indeed, the positive crankcase vent...
..don't plug the rubber tubing, as it allows vapors and built-up pressure to escape from the valve cover..
..i simply doubled it around and tucked in between the other tubing/cables that run down the left-hand side of the engine..
..in some scoot forums, ppl will say that the scoot really needs this hooked back into the suction of the carb's air intake, with an oil "catch-can" inline...
..i've not experienced any problems wit leaving my tubing open on the end, just have to wipe it clean from tme to time...
peace
