fredsaprilia Posted January 21, 2009 Share Posted January 21, 2009 Hello everyone.. I have just purchased a lovely rs 125 yesterday and rode it today, as fun as it was (which it was) it has a clutch problem but im afraid i just cant figure it out.Symptoms: I Can start the bike in neutral fine, however i then change into 1st using the clutch and before i have even let go of the clutch the bike lurches forward and stalls, why is the clutch biting when the clutch lever is fully engaged? Now heres the Odd part if i rev it maybe 5000 revs and change gear with the clutch in it will change into first with no hassle(plates slipping?) and if i keep the cluch pulled after revs have calmed there is no bite at all (hasnt any pull anyway, possibley harder to push than expected though), whats with that? all though my brother says that with the clutch pulled in, in gear you can feel that pushing the bike is harder than is should be. Any ideas much obliged. thanks. Quote Link to comment Share on other sites More sharing options...
Stu Posted January 21, 2009 Share Posted January 21, 2009 first of all try adjusting the clutch cable properly and changing the oil in the gearbox i think these have a separate oil for the gearbox if no joy with that then i think its time to take the clutch apart and inspect it i recon the clutch basket will be knotched and causing the clutch plates to stick and not disengage properly Quote Link to comment Share on other sites More sharing options...
fredsaprilia Posted January 21, 2009 Author Share Posted January 21, 2009 This is the thing i cant adjust the cluch cable anymore as the biting point of the cable is practically all the way out, as in lever almost fully extended, Ill will try the oil change though thanks. Also while im here how easy is it to work on the clutch with an older brother machanically minded? Quote Link to comment Share on other sites More sharing options...
Stu Posted January 21, 2009 Share Posted January 21, 2009 there should be an adjuster at the lever that you turn out to take up the slack that will bring the biting point closer to the bar Quote Link to comment Share on other sites More sharing options...
fredsaprilia Posted January 21, 2009 Author Share Posted January 21, 2009 ok ill quickly do that now.. Quote Link to comment Share on other sites More sharing options...
Stu Posted January 21, 2009 Share Posted January 21, 2009 you should have around 3-5mm of play before you feel resistance Quote Link to comment Share on other sites More sharing options...
fredsaprilia Posted January 21, 2009 Author Share Posted January 21, 2009 resistance when pluuing the clutch in? Quote Link to comment Share on other sites More sharing options...
Stu Posted January 21, 2009 Share Posted January 21, 2009 yes just gently pull the lever right at the end and you will feel the free play Quote Link to comment Share on other sites More sharing options...
fredsaprilia Posted January 21, 2009 Author Share Posted January 21, 2009 yep dune that and there is no free play at all it is all tension and i cant make any play at the lever end of the cable. Quote Link to comment Share on other sites More sharing options...
rollazuki Posted January 21, 2009 Share Posted January 21, 2009 wind the adjuster in until you can waggle the end of the clutch lever back and forth about 10mm. This is free play. As you pull the lever in then, it should offer no resistance for the first 5-10mm or so, then start to bite, and operate the clutch. Quote Link to comment Share on other sites More sharing options...
fredsaprilia Posted January 21, 2009 Author Share Posted January 21, 2009 ok ill try again and also i just read this 'The RS125's high first gear means slipping the clutch is a necessity up to 15 -20 mph' what does that mean? is it related to my problem?

Guest Posted January 22, 2009 Share Posted January 22, 2009 ok ill try again and also i just read this 'The RS125's high first gear means slipping the clutch is a necessity up to 15 -20 mph' what does that mean? is it related to my problem? adjust the clutch at the lever using the adjuster, if this doesn't work (as in you've wound it out over 70%), wind the adjuster all the way back in and follow the cable to the engine, and adjust here, then fine tune using the adjuster at the handlebars, again leaving freeplay..slipping the clutch, generally give the engine a little more revs to aid changing gear.. so add a bit more throttle when clutching Quote Link to comment Share on other sites More sharing options...
fredsaprilia Posted January 22, 2009 Author Share Posted January 22, 2009 is it not bad for the bike to throttle to aid changeing by slipping the clutch on purpose? because my mate had my problem on a rs 50 and he ignored it (wise?) and he had no other problems with it?

Guest Posted January 22, 2009 Share Posted January 22, 2009 it does no harm. its just how it is for that bike.. i wouldn't be surprised if it was common on all 2 stroke Aprilias... Try google, you might get more info there..old american muscle cars did this... its known as double clutching.. clutch in, out of gear, revs, in gear..you can actually get by without a clutch temporarily by revving before dropping down gears in a car, as you increase engine speed to match a lower gear ratio..

fredsaprilia Posted January 22, 2009 Author Share Posted January 22, 2009 WooW well what a revelation, this does take a load of my mind, and i did think it was wierd that it worked fine when its being running for a mile or two. Although i would like to hear another person agree with this theory before getting to excited at the prospect of saving money and effort, but i probly should still adjust the clutches biting point so i have some free play, possible will get down at the weekend, Its a great bike btw anyone who is interested, if you can afford to treat as it deserves you will have alot of fun. promise.
