I say get a bigger carb for that 240 kit then jet it !

if i could afford it right now i would but for now its a no go...

That stock pipe is going to hold you back.

If money is tight investigate a used aftermarket pipe, not a DG, before you purchase a carby.

The stock carb will work better with a 240 and pipe, than a 240, stock pipe and large carb.

As to jetting, #280 to #300 main with the needle in the middle slot.

If you premix at 32:1 up the main one more size.

Start big and when broken in plug chop.

If it boggs during the inital break in, lift the needle, .

Do not exceed 3/4 throttle for 2 tanks of gas and then plug chop the main.

[alexdockery]

For sure dude! I want to get a carb to!

 

[alexdockery]

where do you guys think my pilot should be at?

 

[Blaaster]

Stock carb, stock pilot #32.5

Adjust idle after making sure that the float level is correct.

So I decided to go with a stock bore cylinder cause my big bore was too damaged to repair, but I'm going with a higher comp weisco piston, and im keeping the stroker crank. what should my jetting be now? I'm thinking 230-250?

Let me know if you find a high compression piston, because as far as I can remember they do not exist..

 

[alexdockery]

Oh sorry I know that most if not all wesicos are higher compression ratios in my four strokes, comon man I'm new at this 2 stroke thing!!!! Lol

But narmura makes hi compression pistons apparently: Namura Hi Comp 060 Over Bore Piston Kit 1988 2006 Yamaha Blaster 200 67 50mm | eBay
