Ok, 2001 cr125r with 2 hrs on new top end. Mint condition. It has older fuel, and an older spark plug. Im thinking new plug, new gas, and taking it easy for atleast another couple hours. What oil do people run in the cr's? And it has a PC woods silencer and arrester. Stock reeds, should i go v force or boyesen? Its a trail bike, and a cr125 so the low end needs help. Im going to change sprockets too. What should i be at? Front and rear. I have a 51 and a 53. :ride:

It's broken in by now already.
Have an extra spark plug on hand.
Fuel older than 60 days?... pitch it.
Establish what stock gearing is and add 1-2 teeth to the rear (probably 2)
The V Force system may give you better low-end response.
I never liked more FWW on a 125, too hard to get "on the pipe"... when riding a 125 you just got to get use to heavy clutch use and a sliding, swapping, roosting rear-end.

Congrats! I have that bike but my weight and riding style are probably different. Here's what I run - stock gearing, PC pipe & sparky, Boyesen dual stage fiberglass reeds, PC exhaust manifold (watch the stocker they are prone to cracking), o-ring chain, my jetting changes quite often and my suspension is set for me. See, there's only you, and seat time, that can decide what you need.
The v force will help the entire throttle range. The weirdo gearing is your main enemy, imo.
