i herd that if u take the choke out it increases airflow and i saw that they make caps to cover choke hole......so i took my choke out and filled the hole up with jb weld but when i put it back together it runs worse.....why would it run worse do i have to change my jeting , can anybody help me?

I took my choke off and put a cap in it too. My bike has a stock head, cylinder, and carb. I haven’t jb welded it yet, but I want to soon.

My bike seems to run fine since I put the cap in, however, I have these parts: a head breather hose, Uni air filter, Kitaco cdi, HRC cam, and a Two Brothers pipe. I did notice my bike had a little less bottom end power, but other than that it seems faster without the choke.

What other parts are running on your bike? That might make a difference. I haven't jetted my bike yet even though it probably needs it. It pops a little when I let off the gas and when it revs out. I have my needle on the lowest clip, but I am thinking about adjusting it again because this is the setting I had before I took the choke out.

Good luck experimenting and if you figure out the jetting let me know. Later

sounds like the bike is getting to much air?????????????does the spark plug look lean????? maybe rejet up to a 62 main to give it more fuel

i bought a 60 and 62 and used the 62 straight from the get go....seems to help alot..rejet with a 62 main..air screw 1 1/4 to 1 1/2 rip out the spark arestor of the exhaustand modify your air box...if you can't find the jets check out yamaha of troy...really good people
