Hi Dan, I have never run the motor as I ran out of funds before I could finish the build. I assure you that every peice is new however (except trans which is still in great shape). I took the trans out of an older CR125, ordered new engine parts, and built the engine from scratch. Gas has never been put into the tank, carb or engine.
I can get receipts from Shark Shifter and Fastech Racing that show everything that I bought new.
It shifts through all 6 gears, I just never got a chance to run the motor. I have pictures of the build and if it would make you feel more comfortable I can tear the motor down to component parts to verify that they are new and unused, except the trans of course.
If you can text me at 847-477-2131 I can send you pictures of the engine assembly as I documented the entire build as I was going along.
The kart is in amazing shape with new parts all over. I really wish I could have finished the build but unfortunately I was not able to do so. I will be moving out of state and I will not be able to take it with me. If you are in the area you are more than welcome to stop by to take a look at it. I also am including a second cart stand and some misc. engine tools for the CR125 that I used for the build, I just forgot to list those in the sale thread.
