4 mil questions

[blueovalboy50]

I am thinking getting a 4 mill stroker kit and bigger pistons and a cool head. I have the chance to buy some Keihin 38mm pwk. will these work with a port job or are they too big? also is it hard to find chokes for these? both carbs are missing them.

thanks

order the chokes from keihen's website. and for carbs, it depends on the type of riding you do. i run 35's on my 4mil cub but its a duner....

depends on who does what and sets ure motor up. but 35's most the time is enough. bigger pistons dont do much , unless you really get a big bore... but in a stock motor cyl that will make ure tranfer sizes smaller... overall you need to ask yourself what you want to do with the bike.

If you are going to be running stock ported cylinders I would run Keihin PWK33's. If your going with drag ported stock 4mill cylinders or a duner 421cub then I would go with PWK35's. I wouldn't run 38's or 39's unless I was strickly drag racing with a cub.
