i've never heard of anybody using anyhting bigger tahn a 34 or 35 mm but if you say a 39 works, then sweet
 
hmm i wouldnt know how far i go, i measure in time....i dont have a meter....lol
 
that carb is way over 100, i tried 115, and was outbid....too rich for me....i dont have that much money right now....
 
Well the carb is finaly here and yes...... its fuc***ng huge, but have enough space to install, and already have an idea on how to build a big enough boot :D
Will let u guys know if a 38mm pwk works... bigger isnt always better ? hummm lets see... ya I know, I'm stubborn as a donkey :D

hey my kx runs that same carb. and ive used it on my blaster. I got a SMS intake, wich i think they said is only for 33-35mm carbs, but i got the 38mm to sqeeze in.
 
Can you tell me what main jet youre using? (just so i can start close, and then fine tune it)
Also did you use a spacer when instaling the +4 crank, if you did how tick is it?

i think with the 38mm carb i was at or right around a 160. I do use a spacer plate for my crank, however im also running a 115mm long rod in addition to a 4mm crank, so my setup will be differernt from yours.
