Hm.. But main jet size should not affect my start up right?

Should i adjust the screw that controls the air/fuel mixture?

Btw I'm still running in the bike so have not gone above 6k rpm yet

 

Tuning the mixture

 

1) warm up ur bike by riding it abit for say, 5-10min

2) put u bike on the stand while engine is running

3)get a nice long flat head screwdriver and turn ur screw all the way in, then one turn out.

4) now rev ur bike to around 4k rpm(this is just a gauge) and hold it dead still there. its important that the rpm is constantly at this position.

5) with the rpm at 4k, slowly turn open ur screw. u will see ur rpm rising a little, then it will come to a point where there will be a big jump in ur rpm.

6) close ur mixture screw and count how many turns, then open it back up one turn. repeat the above process at least one more time. u shud get similar results(with regards to number of turns) on subsequent attempts.

 

Ah Seng off-tuned my bike in that sense that it takes a throttle to keep it running. I feedback the problem to him and he repeated his process, now it's better. In fact because he tunes by ear, when he gets distracted the tuning just doesn't feel right.

hey, just to clarify. is there anyway to reset the mileage on the bike? maybe a engine rebuild or overhaul or sth. cause i was told by the seller that if i wanted a low mileage ill have to buy a new speedometer costing about 400dollars. but that doesnt rly makes sense to me.

 

**** bro, what nonsense is he spouting? Kinda like a f off statement.

[Feelicks]

not sure abt e newer models but e older ones have a knob beside e speedometer, juz twist it till it resets... there shld b some button combo to press to reset e figures on e digital speedo

[lacrimosae]

So normally the bike should start without throttle and start immediately after pressing the start button?

Do we need to use choke in singapore climate?

 

Yah, was thinking my bike could be running leans as its a stock bike with arrow exhaust.

Saw sub zero mentioning somewhere back that stock with arrow exhaust should up 2 jet sizes?

 

Yes, bike should start on one crank. If you have to hold your starter button down for more than half a second, your idle setting is off.

 

Also, the 28mm carb runs best on the 135 main jet. (I learnt this from Subzero)

 

Yup. Change your main jet to 135 if you're using 28mm stock carb. It should be fine. Normally, i don't turn on the choke in the morning UNLESS the engine stop due to insufficient petrol flows. You just turn it on for about 10 secs than off it and let it idle on itself.

 

Hi Sufie, try not to use the choke constantly on for too long. Just a few seconds to richen the mixture slightly during start-up to give your engine extra fuel and lubrication. Leaving the choke on presents 2 risks- fouling the spark plug or forgetting to turn it off before riding.

 

Hi,

 

For 34mm flat-slide: Is it ok if i put the needle clip on the top ?

 

And also, i find it hard to put the throttle cable inside the hole! Help!

 

Thanks

 

Yes, you can change the needle clip position.

 

Yes, that nut is a real b1tch to screw! Just use a flathead screwdriver about 3-3.5mm wide to screw it in.

 

Hm.. But main jet size should not affect my start up right?

Should i adjust the screw that controls the air/fuel mixture?

Btw I'm still running in the bike so have not gone above 6k rpm yet

 

Yes, main jet shouldn't affect the starting. Follow dDtim's advice on tuning the idle.

There are 2 mileage readings on out bikes:

 

1. Odometer- Tells total distance travelled on that speedometer unit. This cannot be reset normally. This is because it is to tell you how much the bike has travelled in its lifetime. Of course, you can change the value if you know the tricks of the trade... The analogue odometer can be reset, and so can the electronic unit. Heh heh...

 

2. Trip meter- Tells the distance travelled per trip. This can be reset to measure say, the distance between your home to office. Or just to keep count how many km you can travel before you see the fuel light come on.

 

**** bro, what nonsense is he spouting? Kinda like a f off statement.

 

Maybe he meant the odometer. If you want to physically SEE the odometer counter reset back to zero, you have to do a factory reset. Or replace the unit.

That knob resets the trip meter, not the odometer.

Just to confirm, the correct setting is at the point where the rpm jumps up or the point just before it jumps up?

Ok I itchy finger go try and turn the knob to increase my idle. increased it to 1.5k idle, then rode off, engine die after moving a few meter. cant start after that. tried to push start, engine started but then bike will jerk and stall after a few seconds.. haiz.. should not have itchy finger..

 

then to add on to my distress, i try to lift up my fuel tank and the metal piece at the btm of the tank fell out and into the bike.. cant find it now zzzzzzzzz

 

Any common spots that it might have dropped to? looked through the top of cant seem to find it.. shoke the bike but it didnt fell out either.. think its caught somewhere

Did u switch on fuel knob?

 

Anyway, fuel tank btm doesn't have any metal piece.

[Sub Zero]

Be it he's cuming or not lets not make it an issue right.. If he turn up, den its gud at least we cn clear things up but if he's not der, its ok, perhaps sum other day he wil turn up who knows... N as for us, we will jz continue wif our mit up, chilling n riding... N tomorrow I'm bringing along sumbody whom i respect most n who has been standing all along wif me till today.. I will introduce him to u all... Chill ok....

 

Well, just to update everyone here, we had an awesome outing as usual last night, rounded off watching ManUre lose to Barcelona! Woohooo!

Sadly, the person who said i'd piss in my pants did NOT turn up. This is after telling Eddy so confidently on friday he's confirm be coming, he didnt reply to any of Eddy's sms asking him if he was coming on saturday. Coward springs to mind, but somehow that word doesnt suffice. After some discussion yesterday, I've decided to drop the matter and move on. I dont want such things happening again. However, in my limited 'powers', I'm banning spark315 from any majormeetup I organise, and ordering through any Mass Order I conduct. I will also be informing Amin of the Cagiva group of the situation so he will not be invited to a Mass Meetup that I'm planning for the future. I simply dont want to see his face. The rest of you are welcome to associate with him if you want to.

 

I'm a lover not a fighter.

Wah... say until like tat sia... Hehe..

I didnt adjust the fuel knob so i think its on. There is this round metal piece that is attached to a rubber at the bottom of the screw hole for the tank.. it came off

[Mdsufie]

Well i guess that Mr.P.I.M.P (LOL "PIMP"! ) had too much love from you that he gets too jealous and heartbroken.

[Sub Zero]

Oh yes.. Before I forget.

 

Great time at PG today. Everything was fun, except we got stuck in a heavy downpour on our way back just before JB customs.

 

Blaquepearl's bike was plagued with electrical problems, and he had to retire from the race. Kudos to the 2 other Aprilia riders, Belray and Spain No.1 for doing a good job and finishing the race. Even as a spectator, I found it gruelling!

 

Results? The first 3 were all KRRs from Abboy racing. It was a 1 2 3 finish for them. Awesome stuff. They were so fast, that the distance between the 3rd postition and the next the whole front straight!! Respect to the Krr and their riders! Looks like this time the rain didnt help anyone. Hehe. I believe the Krrs were doing below 2min. I timed some of the RS125 riders, will update you guys in our next meetup. But I can tell you one thing, no Aprilia RS125 rider did better than 2.02plus. Hehe..

 

Wish I had the money, stamina and most importantly talent to race. Hats off to Blaquepearl for doing his best and graciously hosting us in his pit.

bro, u turn ur mixture screw or air screw till u idle at 1.5k? if its e big shiny one dan juz turn it back down to 1k-1.25k... if its e small one found near e bottom of ur carb dan u've screwed up ur idle circuit, gotta follow strictly wat dtim posted step by step to get ur ride back into ridable condition

 

Did u switch on fuel knob?

i think he's riding e post 06 models, they have a small steel nut tt fastens under e bolt which locks our tank in place.

[cheraxx]

haha exactly, i felt like it was a F-OFF statement. still looking for a >06 model RS. damn scared buy tio lemon!

I didnt touch the air screw yet.. Just the big screw that controls idle RPM. I think I might have turned it too rich as the exhaust smells of petrol when i attempted to push start it

 

Yup the steel nut that fits into the rubber grommet under the tank.. came off so easily, lifted the tank and off it went into the engine bay.. doesnt even come out after shaking the bike left and right.. dunno where issit hiding. Now i cant screw back my fuel tank as well -.-"

 

Its a very unfortunate day for me

oh, dan ur prob issin tt bad, juz turn it anti clock wise till e rpm's near 1k... as 4 ur fuel knob... tt one's a headache, try removing ur airbox to have a better look ard ur rear shock area... juz look 4 e screw tt connects ur airbox to ur carb, screw it out to loosen e air box n u can pull e whole thing out... its safe simple procedure which wont **** up anything

This, in my experience, is the best way to do it. I've personally have seen ah seng use this method(but i did not learn this from him). It takes practice, to keep ur throttle steady and coordinate the screw turns while keeping ur throttle still. Also, its more difficult to be done on the 28mm phbh carbs due to the position of the mixture screw. U might need to get the help of someone to open the throttle while u adjust the screw.

hm.. problem now is I cant even start my bike up anymore.. not sure how to adjust the fuel knob back like that

Hopefully didnt damage the engine when the bike keep jerking and dying due to push start..

 

So what are my option now is only to tow to workshop to get it fixed? Not confident to do anymore DIY now man.. the more I touch the more problems i create -.-"

What are the operating hours of 37 motoring?

[vteclee]

haha exactly, i felt like it was a F-OFF statement. still looking for a >06 model RS. damn scared buy tio lemon!

 

buy blackwidow bike ... faster go find him ... his bike got everything... u wan stock also have.... FBE plate very nice bike ... his number .90089112.

oh man.... thats very bad... hope its not sucked into the airbox into ur carb and there goes ur block... siao liao... all the best... if really happen to find it inside ur block please post up on forum. haha

[slicer]

oh man.... thats very bad... hope its not sucked into the airbox into ur carb and there goes ur block... siao liao... all the best...

 

U mean the nut? its actually not that small to get sucked through.. and besides there is the air filter and I dun even think the nut is small enough to go through the carb.. dun scare me leh..

[vteclee]

nut confirm can go thru air box snokel. how u know got filter u got open and see ?? most riders here either open pod or airbox but no filter only a few uses filter. haha u got check bo... WAHAHA

You are so mean bro!! Guess what? It seems a rs125 can go 200km/h plus at PG... but takes turn 2 at 120km/h.. Weird! What's your take on this?

 

sounds exactly like sth i posted awhile back...

 

It is exactly the same! Mr Ashraff, do you want to sms me your account number, or do I just get a free sprocket? Gimme special price ok?

Btw, how did your interview go?

[dDtim]

Vik: 200 plus is insane! You sure about it?

 

Ashraf: Yeah bro I conveniently tucked your text into my notes so I just copied it out. Oh uhm, credits to Ashraf.

 

Law: DIY Meet-up, any loving?
