Stalling on Low RMPs

Recommended Posts

Just wondering If you have any ideas what could be causing my bike to be stalling when I have the clutch pulled in?

It was fine until I adjusted my clutch so it was not sticking out so far and I could grapple it easier.

Just trying to look for some clues so I dont spend all day tomorrow trying to figure it out...

Its an 07 yz125 .. all stock, apart from some unbreakable levers...

I dont know if this is normal but when I was getting into high revs in gear 1 and 2 it felt like I was chopping the throttle on and off. Im hoping it is not the rev limiter... becuase I swear I have ridden it harder than that before and it has not done it..

Cheers for any advice though!

ok I have discovered that I had over adjusted the clutch and it was too tight... hence i have been riding around with it semi engaged all the time :banana:

Mega rookie mistake

So i think im looking at having to replace all the clutch plates. Can someone recommend me a brand that makes decent quality clutch plates?

You adjusted too much I think.. You're still engaged even with the clutch pulled in.. When you adjust your clutch, you want about an 1/8-1/4 in of play in the lever at the perch.. If its too tight, you wont fully engage.. If its too loose, you wont fully dis-engage.. :banana: Also, maybe turn your idle up a touch :lol:

As far as brand? There are many out there and Ive used EBC in the past.. But I havent replaced a clutch in a long long time.. Also, if you do have to replace your clutch, its a good idea to also do a cable at the same time.. They tend to stretch

cheers for the reply

yeh i think i caused myself this problem which could have easily been avoided. Oh well, i guess i learnt the hard way haha

Speaking of idle... does the yamaha manual call it something different? I have looked all over for it in the manual and cant find it anywere.. maybe im just blind!

Sorry, i should know these things haha.

just twist the choke-plunger.

i believe counter-clockwise speeds up the idle (might be wrong on the direction)

just make sure to adjust it when it's fully warmed up.

To adjust the Idle on his bike you do not turn the chock-plunger.

You have to turn the Throttle Stop Screw in to rais the idle and out to lower the idle. The Throttle Stop Screw is located a little to the right of the chock-plunger and under the vent hose. It shouild look like a screw with a nut to lock it in place. It might be on page 4-8 in your manual and its # 14 in the diagram.

oh cheers guys.

I was wondering what the throttle stop screw was.

people have told me i should only need to change the fiber plates but they seem just as expensive by themselves compared to getting a whole kit with springs and steel plates.

It was about 100 bucks for an EBC full kit. and then about 70 for just the fiber plates. Im in AUS so i gota get them online otherwise i have to pay really expensive prices. Do u think i should just get the full EBC clutch kit?
