jetting my 250R

[honda man]

I just bought a 1986 trx 250R and blew it up on the first ride. I just got it back together and cant get the jetting right. It has a paul turner pipe with a fmf Q-series spark aressted silencer. and a k&n filter. I am currently running a 165 main with the needle on the 2nd clip down from the top and it is running really fat. I am a four stroke owner, so this 2 stroke stuff is new to me. It seems to hit the power band fine in third and fourth gear, but 1st and 2nd it hesitates and loads up. any suggestions?

What does the plug look like?

it blew up o nthe first ride ,you may have a bigger problem than jetting anyways it should be somewhere around a 60 pilot and 160 main

the plug was completely melted away. When I did my plug chop the plug was light brown, which is good on a four stroke, but now I know thats too lean, especially in the sand.

I am now running a 55 pilot and 162 main, I just went out and did a 1/4 throttle plug chop and the plug was wet, it doesnt even hardly hit the powerband in 1st and 2nd gear, but when i hit third it runs like a molested monkey. It wont idle for very long either, I was just wondering if maybe thats because its a new motor.
