Hey guys, i just got a new air filter and wondered if iv upjetted enough..its a 17.5mm carb, and iv gone from 90 to 100.. also its only a 50cc ,,,,,,,is that ok ? this is the fliter, its the big one Thankss )
Nope it'l run like shit. and just make induction noise, save it for a 70's engine mate. 90 jet is too small also.
iv got a 100 jet and a 103, take it thats not enough either lol ..// could this stop it from starting? the throttle bit that you put in the carb, sits too high and doesnt go all the way down, bike only starts when u cover half the carb ?? i was told to buy bigger jets , throttle cable and another filter but it hasnt helped lol.... on another note,,If it doesnt work out, ill let you know if i sell it ramo
the main jet only really kicks in once youre going tbh so its unlikely. the slide should have free movement and should close fully, if its doing anything else follow the throttle cable from carb to the lever it will most likely be caught somewhere. how is your carb set up and what type of choke do you ave? as you can probably tell though its alot of hassle for little or no gain
Jonny- Iwish it was that simple. i was told i needed more air? i wasnt sure so just bought them anyway lol ramo- what do you mean by set up? and its a manual choke, but thats pretty much new, i replaced the cable and the bit that goes to the carb. It is a bit of hassle yeah lol, looks good, but doesnt look like its gonna help the bike much
i dont know lol.. i always thought if you wanted a filter like that, you have to upjet, so i did and just assumed it would work.., it may be a 50cc but its had more problems than my old 1600cc fiesta ..what jet would be best to use out of a 90/100/103 with the std airbox ? bit off the topic,, but if the throttle cable doesnt open and close in the carb does that stop the bike from starting ?
It'll be like starting the bike on half throttle so yes. and with standard airbox you want like a 80. If i'm right, anywhere from 60-80. I'm not too sure on rox's i'm affraid.
did you change any of the screws or anything since it was last running? its generally not the best idea to get one or two sizes of jet when your setting up as theres no real way to know whats rigt without trying it out. also throttle cable might be too short?
cheers jonny, hopfully tomorrow will be a good day then and ramo, i didnt touch and screws as far as i can remember, i know to leave the idle/fuel mix screw alone lol.. so i just plug the hoses up and hope for the best haha.. and with the throttle cable, we connected it from the handlebars first and it wouldnt go through the 90 degree bent metal pipe, it got caught inside at the bend.. so we took it apart and redone it starting at the carb, then fitted it to the other end, and it was rather tight on the throttle .. but the thing inside the carb will not go to the bottom , sitstoo high... i just ordered a standard aerox throttle cable from pedparts so surely that should be a straight swap ?? do they come in certain lengths then >?
is their anyway to adjust the cables freeplay at the bars or carb? i know on my rs i have a nut i can adjust to change the free play and give it more slack, which is what i had too do when i fitted a 34mm carb otherwise the cable was holding the throtle open a bit as for the filter, keep it too one side incase you 70 it, but for now make your life easy and get the bike running with as many stock parts as you can.
i dont think theres much room for freeplay mate, the throttle is really stiff .. cant really adjust it at either end one of the metal bits in the NEW cable i ordered has broken, like clear snapped off, so not very happy about that.. we tried 'modifying' the new cable with the old one to see if it could be done, we got it all fitted. then heard a snap.. and about half way down the cable theres a little round flip open box kinda thing.. the metal that holds the other part of the cable in there had snapped. so we got as far as that. seems i need a longer cable.. i think it was holding the throttle open all the time, cos the part in the carb stayed open, it didnt open and close when you pulled on the cable..,,not to mention when it Does start it revs like mad and you cant do anything but turn it off by the key of it dies itsself. i think i will kep the filter as you say if i go for 70cc.. but that probs wont happen til april, i just want her running again! lol , now i got 2 new filters to use, think i will be sticking with the std one for now, as you say, be easier getting it running as stock
unplug the cable and run the bike without the cable? should be able to manualy open it that way to check it idles unless thats not an issue
i think we tried that and it didnt work, and idling has been an issue for some time , if the cable part in the carb doesnt open and close/go up and down could that stop the bike from starting/ idling properly ? if so ill need a longer cable, but i thought theyd all be the same length
today is the day im a happy guy,, my bike is finally running with no seen problems! idles a bit high but i dont really care ))))))))))))) so happy right now lol .. got the stage6 filter on there too running a 90 jet, looks good but ima have to chop up the plastics to get a snug fit ....... its all worth it in the end eh guys? A final touch though...... can anyone tell me how to wire up my R8 style front headlight ? i got them working but dont kno if the wires were in the right places ( high beam/side lights or watever they are) and dont wanna solder them in place to find its wrong?? any ideas peoples ????
best bet is too buy bullet connecters from halfrods and fit them on the old wires and the new headlight, then you can switch them about i wired up my str8 headlight using bullets which crimp on with pliers, took a few attempts to get the right combo of wires so that only one bulb lit up on normal beam and on high beam both lit up, i did this by wiring one light to the side lights as they are always on, then then wired the second light to the high beam congrats on the bike by the way!
iv never heard of bullet connectors before, i was gonna upload a pic of what iv got wire-wise, but cant find me phone lead.. got a red and black wire coming from either side and a white one coming out each of the the main beams, but iv also lost one white wire so looks like ill have to buy a new light anyways think id have to get me stepdad to have a look at that it sounds a bit mad and magical to me Lol, iv never been good with electrics, thanks for the advice tho pal will come in handy ! Thanks mate, hopefully it doesnt die on me and give me loads of dopey problems again.. as if it was the throttle cable that was stopping it... looks like ill be keeping it too, just out of curiosity , with an MOT, is it true mopeds only need like 6 or 7 things to pass one, eg#bike runs, horn works, brakes work , lights work, indicators and so on ? coz i need a horn
http://www.halfords.com/webapp/wcs/..._productId_216827_langId_-1_categoryId_165626 Thats a link to the halfords ones, you can buy a packet with both male and female. Fit the male connectors (the ones with the metal plug showing) to the light unit and not to the bike purely so they cant short outif they touch. Wireing wise the black wires are earth, and go to the black wires on the light you have. As for the other wires you will have a wire that goes to the side lights (on my aerox headlight this is blue, you will want to wire blue to the right hand side. this will leave the right hand bulb on all the time when the bikes running. Now you are left with yellow and green i just had a quick look in the manual and it should be the yellow you want for heigh beam, attach the yellow to the left hand bulb of your bike. the green wire should be tapped up to save it shorting and isnt used anymore on 2 bulb headlights. hope that helps bud
