Default Removing JM250 Chain

Well i had a 14/42 stock and i do a lot of hill climbing cause there is a lot of soft dirt here in TX. I mounted it yesterday so to late on going to other gears before i cut the chain. Check out the pics i posted last night. I didnt have to really mess up the chain the pins i just punched out and i probably can put them back if i want to make longer but not sure. I did notice that the Jet pulled fine but Does the chain have to have an even number of links. I had a 132 and now its 113 but if i let go of gas when running the chain seems to whip and make strange noise but if i press the clutch it stops. Not sure if i need to remove one more link??????

balanis03, have you had a chance to test out the new 12 tooth gear? Just wondering if I would like a 13 on mine!

Yeah outofline, i did take it out about 2 or 3 weeks ago to the same spot i always go. Let me tell you i did get a bit of lower torque that i wanted and i did like it. In the rocky terrain this thing can climb some mighty tough and steep hills. I went on this steep steep hill and thought i was going to flip cause it had a lot of power. But then i took it to the sandy terrain and it did better than before and i got higher on the hill than i did with the other sprocket but im still debating weather to buy paddles for his Chinese bike? but it really gives more power. Im going to ask a buddy to check the bike over and see if he can tune it up better since he knows more than i do. Im also looking for a 30mm Mukuni carb to add to get some more horsepower so that it opens up the engine.

I have ridden a 150 and a 200 with paddles at Pismo Dunes. 150 struggled a little. 200 had no problems. Both of these were '06 models. 250 should be fine with your lower gearing. Im running 15/40 on my '07 250. Stock was 17/40.

Hey MWQ, good to hear from you. I have been asking around this site to see if anyone has put paddles for these but no response. Currently i have a 12/42 and it does pretty good i think but ive never taken the bike out to red sands. Thats what the place is called here. Are the tire that come stock mainly for rocky terrain?

Have you called Raceway or Jetmoto and asked? I know they have some for the 8" wheels. Should have some for the 250's
