Ok about two years ago I bought a Trinity
240 Big bore kit sent the cylinder and head out to them
had it bore honed, Trinity head mod done, Port and polished stage III
with a weisco piston all sent back to me. I installed everything with the
jet that they sent to me started first kick. But I could hear some slight
piston slap I pulled it apart and after measuring it seems they sent me
the wrong sized piston. They re-honed it sent a ne piston and that was
about a year and a half ago. Fastforward to now I finally finishing some
of my car projects and I want to get this thing going so I can trade it in
for a Raptor 700 or 660. Basically my question is does anyone have
experience with this kit? And do you think the stock carb with a 310
jet can flow enough for this 240+cc Trinity says yes but I'm not sure.

If I ever get it finished correctly I bet it would be fast as hell I was pretty
close with my buddy's 400 before with all the basic bolt-ons I had then.

 

The stock carb will work on it but it will probably gain some more horsepower with a larger carb though.

 

Go get an 85 carb, used, A lot of easy horsepower [img]i/expressions/face-icon-small-smile.gif[/img]

 

the stock 26mm Blaster carb is too small for a stock motor let alone your 240. I went from a stock carb to a 30mm on our Blaster after porting the cylinder on stock bore with pipe, and it was a gigantic difference. Now I'm running a 3mm stroker and bored out only 20 thousandths so it's a 208cc or so, and running a 34mm carb off a Honda 250R, and it works very well. You can use some more carb. The 30MM flat slides will work with your stock intake so that's the most economical way to step up.
