Poor man's carb mods?

Recommended Posts

Okay so a new jet kit is $75, a new jet (singular) is $6. I really don't have the money to spend on a jet kit nor the $500+ for a carb.

Since individual jets are $6-8 I was thinking of just getting a 155 or 160 main, any thoughts?

include a 25 pilot? 27.5 pilot?

needle required?

My shop said we can trade at no cost if wrong jetting.

06 sm

current mods:

2 1/4 hole in airbox (will widen when jet decision is made)

spark arrestor opened, and 2 half inch holes in 1st baffle

right now bike runs good but needs to be in 4th gear at anything less than 45mph and similar for other gears (needs for the gas to be on)

Getting individual jets and an appropriate needle is fine and can save you some $$. However, if you're talking about a specific jet kit, what you're paying for is a custom needle (a pair, actually) that you can't buy from a dealer, a reasonable selection of jets that you're going to need anyway since the air temp, pressure, and humidity changes seasonally, if not daily, and perhaps most importanly, the vendor-researched matrix of what needle/clip/jet combinations to use as the weather changes. For me, saving maybe $40 isn't worth the pain of buying individual parts.

replacing jets wont fix the issue.

tape the hole back up and ride. thats the cheapest mod.

Bike comes stock in lean condition, add more air and less back pressure = extra lean. Add a bigger jet...get more fuel....and vwhala no more lean condition = more power.

What am I missing?

your missing understanding how a carb works,,and reading morwe about it i think...

the main jet only offers fuel to 3/4 to wot throttle. you still need to fix the middle range of the throttle position which is done with the aftermarket needle as previously explained why you need a different needle..,the stock pilot jet will have to be changed to a 25 if your going to keep the stock fuel screw, if you get the extende fuel screw the stock pilot will do,

The needle and the spring to name just a couple. As far as I know you can only buy them from a kit for the Minkuni.

just a thought, but i did my cvk40 swap for just a little over what a jet kit costs. more bang for the buck (i feel) than jetting the stocker.

your missing that "Bike comes stock in lean condition" is the needle.
