no ideah lol. Uhh where is it and how would i do that explaine please if u think thats the prob. thanks

[Mack]

That bogging your experiencing is cause your jetting is not right. If your unsure what to do go see any local bike shop, they shouldn't charge much to help you jet it. But... if your up to it, we could work through it.

[mad man]

I think I'll take it 2 the shops..lol, i will get a new plug and then i'll c what happens from there. How much u recon it will cost??

thanks

I dont agree or disagree...

But usually rejetting a bike is dne when a component is changed ie bigger exaughst richer fuel ..........not the point...

If it ran fine and dosent know I assume a problem not a calibaration.

Try pulling your carby apart


Carby for illustration purposes only....

No need to be scared... Get a table a a clean towl.. Lotts a small parts and take it one step at a time and you will have no problems....
Reassemble and if dosent run well take to mechanic.....

Your problem sounds typically like fuel or at least when we have simillar problems at work its fuel....

Check the stupid things as well ...Fuel supply hoses.....You never know and its the simple ones that will shit you...

Sorry forgot to say The carbs above are from my Suzuki RG250 Smoker..... 47hp......

a lot of bikes suffer from this bogging and can be rectified with tuning. Its hard to tell though, if we don't know the state you keep your bike in. If your filter is cheap shit or you let it get clogged that could be the problem. If your running a plug that is way off ideal as well that could be a factor. Check those two simple things first. An ideal plug for the 125 is the NGK CR9HRC, there are others but this is a safe choice. If your still suffering from this bogging we'll look at your air/fuel screw and pilot jet.
