does that cab have to be apart to adj it?

 

sorry for the posts i got help..... i have lots of spear parts so feel free to call and see if i got any thing you need..(719)650-5850

 

on the 2008's you need to pull the bowl off the carb and remove a plug to change it out for an external adjusting one like the R&D Flex A/F screw.

Otherwise just remove the bowl and you'll see it towards the front of the carb.

 

thanks villain

 

my wife bike has a flat spot it the gas from idle... if you try to floor it from low rpm it will bog and die if you dont let out of it or get past that spot the get after it. you dont realy notice when riding. it has gytr full Exhaust and gytr intake with the box cut out so you can just look under the seat and see the filter hanging there and 160 main jet and rev box.

 

That has nothing to do with the fuel, it's the accelerator pump that is the problem.

To fix that you need to do the fallowing mod.

Take that black cover off the side of your carb
the black arm and the arm with the screw/spring put a ziptie or safety wire around the point that those 2 arms touch.

You're getting the bog and if you push the throttle in while you have that cover off you'll see that the silver arm comes off the back one then the black arm plays catchup that space is the bog.

Putting the wire around those 2 arms you'll no longer have that gap and the bog will be gone.

The photos are from the spring mod another way to fix the bog but don't loosen the throttle wire. Just pull the cover off and put the ziptie or safety wire in there. I did safety wire and it works better some people have had problems with zipties braking after a while.

 

villain thanks alot man i will try that and let you know how it goes.. it sounds like its a prob youve delt with......

 

do you thank a 160 jet it to big not sure of the ele of lamar colorado

 

that looks a little lean. You might want to go up to a 170 and get the NCVQ needle, and put that on the 3rd clip from the top.

The bog is something every YFZ owner has messed with. It's a known problem but there is an easy fix.

 

any on looking to buy some fox shocks or gytr heel guards

 

so villain put the wire around the accel pump arms and the bog got alittle better but was still there so i took the open tip off and put the three hole tip on and with the more restricted tip the bogs gone......??? with the restricted tip, less air flow means more fuel right so with the open tip im to lean?
look at how they cut my air box out...

 

yeah, I suggested going to a 170 main and the NCVQ needle will richen you up to the right area to start fine tuning with your a/f screw. I personally wouldn't want to have a "air box" like that. I just took the lid off and that is more than enough. But I don't ride dunes. But even then you'd want a foam filter not the GYTR- K&N style filter

 

any one got a air box for sale.....lol
