Default Clutch worn out?

     

On my cr125 I know its an older bike and clutches don't scare me, in fact my uncle said he can replace one in half an hour because his kids used to race them. But im not sure if mine is slipping or if its just me after 8 year and im not good with the clutch. When i try to "launch" or go from stop to start fast like a "hole shot" i rev it up and let it out slowly and it bogs down and will only do a slow start. like i need to play the clutch a lot more. I am in no way great with the clutch yet and maybe i need to let the bike warm up more but could it be the clutch plates? or do i need to adjust the cable looser or tighter? I know thats a lot of questions and probably a simple answer but i need to know if i need to get new plates or not
Thanks,
-Isaac

If the clutch was going out it would not "grab" when you let it out. That means the motor would be reving, but the bike wouldn't be moving. Since you say that the bogs down when you let the clutch out, I would assume it's taking on the load, but not making enough power. I'd start by checking the carb and then the compression based on what you've described.

Thanks Gusco. I heard the same suggestion from a few other people. I'm not good with carbs but im sure we can figure it out.

Also, it's a 125. Those just do not make power unless you are on the pipe. Even on my 250 working the clutch a little off the line helps keep it in the power band.

Should i be revving it higher then to get in the power band? Even when i release the clutch "slow but fast" it doesnt seem to go

So quick starts aside, how does it do just out riding it? Say rolling on in 2nd gear, does it start making power higher in the rpms or does it seem to flatten out and not give you much?

I noticed in whatever gear I'm in..if I'm accelerating fast the bike wants to go through the gears really fast and I accelerate fast as hell. But when I'm not in the powerband and I'm at low rpm's the bike wants to go, but wont go as fast until it gets the rpm's up..then it'll really get going.

Check the float height first, then you'll want to adjust the jetting. What does the plug look like when you pull it out?

I think for now ill start with cleaning the carb and having my uncle look at it since he knows more about them, I think once it warms up also it will do better,
Thanks for all the help!
