Even when it was on the pipe, the engine didn,t sound right. Check spark plug,plug wire, wore piston,reeds,vent tubes from carb melted,air filter. A properly tuned  05-07 cr125 sounds great, and has awesome throttle response. Install a rad valve-polish the inside smooth, install an icat, with a stock pipe the engine is better than a new YZ 125.

Not too sure about that but I'd love to see a comparison.

I wrote that while I was stranded at the Chicago terminal, trucks in the shop again.Sitting in a plastic chair for more than a day,waiting for a ride to go home,it,s my 12th truck since march,which is crazy. With those up grades the cr125 runs much better,huge improvement bottom though mid range, making it equal to a new YZ125. Then it comes down to who can brake latter and get though a corner the fastest,then getting traction to drive out of a corner, getting your weight back on the rear wheel to hook up. All these movement are to be extremely agreessive,while being smooth. There now your a 125 specialist, ALL  450,s will fear you. ;D  PS I,m on ice bags from driving that junk truck,can,t wait to do it again,not.

If it was a 4T the bill might have been a bit higher that what you will see.
Yamaha CT3, RT3, MX125, SC500, Toy Prius, Diesel F250 (it all balances out)

it was my mates bike, he puts the fuel in and i dont think he is stupid enough to not mix the oil hahahahha, i hope he isnt that stupid anyway, he said it was about to blow up anyway because he has never changed a piston in it for a good year, and he has never changed his air filter or gear box oil, but i have told him now to take more care of his 2 smoker :)

Deffinately rideing a gear too high all the way around the track how dirty was the air filter? sounded like it coulda been totally covered with dirt and not allowing the engine to breath at all.

:-X  How can you ride a bike like that and never change the airfilter or gearbox oil. You're just on a mission to destruction then.
