New Jet Kit

Jump Master2010-08-10 12:23:10 +0000 #1
In a previous thread I was complaining about the quad being sluggish. I added the Dynajet kit this weekend. What a pain in the a$$ to take the carb off!!! I added the recommended parts to the carb for the factory pipe and the right jets for my elevation (~800'). I also turned the fuel mixture screw 2.5 turns out.

Do I need to do anything else after this? I was planning on installing a brand new spark plug and then taking it for a ride to check to make sure that I haven't leaned it out to much. I willalso be adding a K&N air filter. Will I have to change anything on the jetting again or is what I did sufficient?

If it runs fine leave it.....as far as your filter....not sure.

I took the quad for a spin this weekend after rejetting. I went for a half hour ride through some not to bad bog. I took the spak plug off and this is what I found. Can someone let me know if the color on the sark plug is good or not?

I would go up one jet size.....almost too white. See what it does with one size bigger. How did it run?? It looks close I would try one bigger though to just see.

to me it looks to be a little lean . u want a little more black up the tip .

i would run the bike till it warms up and screw in mixture screw in until it start to run rough and then slowly turn it out , the rpm's will start to come back up , keep turning out until rpm's level off then turn back in maybe a 1/4 turn and u should be good to go

That will only fix his 1/8-1/4 throttle.....he will have to go up one jet size.

Also if it is running fine 1/4-3/4 throttle leave your needle where it is.
