How much is this bad boy?
And how the hell does it increase MPG?!

 

$275 from jetsrus.com.. how does it increase mpg? No idea man, but it does produce a better venturi pressure difference, more air flow, and more power on the bottom end.. what took 3/4 throttle with the cvk now only takes a blip 1/4 throttle to acheive with the flat slide mikuni.. seems counterintuitive that a pumper gives better gas mileage but it does

 

damn.. $275
Is it worth the money?
I don't have a 351 kit yet.. I am assuming I should do that first before dumping $ into the carb.

 

Many have said the 351 is more bang for buck than the pumper carb. I don't have either yet, but plan a big bore (351)...and maybe a pumper but not sure because I like the smooooothness of a CVK carb.

 

Yeah.. I think the 351 is the next mod

 

351 is the best upgrade so far
cvk is smooth, and you get good power with cvk and 351
tm36-68 brings the 351 up to the next level - way more torque on the low end and midrange, snappy, takes alot of tinkering to make it smooooooth like the cvk down low... when you first get the carb, you will pull out your hair, take it off the bike, throw in the corner like i did .. it took me weeks to dial it in.. now its perfect... bike starts without throttle, starts out smooth, snapps your head back when you throttle it, and added 5mph to the top speed.. and lowered gas consumption

 

Final tuning of the pumper tonight.. nice roll on 2nd gear wheelies..

 

I went to the website. How did you know what carb to select? I want to upgrade to a 351 big bore next year. My bike is all stock for now.

 

Mikuni carburetor TM36 (MIKUNI # TM36-68)$277.51

 

Out of all of the carbs available, how did you know that's the one. It does not say for a klx250. I know this is a dumb question so please forgive me. I'm only trying to educate myself.
