More Power into my 2003 KTM 125sx

[JakeH05]

I have a 2003 ktm 125sx.It seems to lack a definite top end hit compared to some of my friends bikes like yz 125's and just lacks alot on the top resulting in more shifts.I dunno if its the 5 gears instead of 6 or what.Im thinking it could be jetting,reed valves,need aftermarket pipe,top end is getting worn,or timing.Does anyone else know what i can do or if any of this works and makes a big difference.really need help!!!! appreciate it

When was the last time you cleaned your power valve?

When was the last time you changed the rings?

 

[JakeH05]

never did checked either of em got it in march of last year from what i understood it is still on the stock top end

 

[JakeH05]

Im thinking about getting a fmf sst or fatty pipe or pro circuit pipe any of yall ever used em which one you like better

 

[Denny1068]

pro circuit is more for bottom and the fatty makes it rip in the top...the sst is a more all around balanced pipe

Before you spend $200 on bling, get a $150 top end rebuild kit, your bike is tired.

This (and a fresh top end) will make a new bike out of it. Save your money on pipes and stuff until you fix this.

[2 strokes for life]

I was doing some poking around today and found a way to control the power delivery for your bike and here is the link

Hope this may help.

I found a major problem with it today. huge carbon buildup in the pipe restricting a whole lot of air from escaping.I also have another question on getting the timing right.Ive read alot on how to adjust it but can anyone explain it better.

 

[JakeH05]

the timing is def. off and i think somethings wrong with the power valve.Ive never had that problem with a bike before.can anyone tell me how to adjust em.

 

[JakeH05]

never mind we fixed it i still believe the power valve is sticking tho any ways to solve this without pulling the engine apart but we prob. will end up taking it apart just wondering
