Jetting Troubles

[kamp0ss]

I need help with my jetting as soon as possible, and I could use your help. Here is my information:

 

Pro Circuit Pipes

TORS Removal Kit

K & N Airfilter w/out Lid w/box

VForce 3 Reeds

 

200-500 ft above sea level

60-90 degrees

 

I currently have 250 Mains 25 Pilots, Air Screw turned out 1 turn and Needle on 3rd Clip. I have mains up to 290, and do not have any pilot screws. Please help!! I need help ASAP, as I am going riding Friday-Monday.

 

Thank you in advanced!

Sorry forgot to mention that part... It is bogging when I give it gas. When I give it gas at idle the RPMs hang briefly before they job..(My idle screws were fine prior to the air filter, would this change that?) And lastly when I pulled the choke while riding it bogged, so it seems I am riding really rich for some reason. But I doubt I need to go to 240s..

So it cleans up after the low rpm bog and pulls nice from about mid all the way to the top of the rpm range?

 

Fire the bike up and get it to operating temps. Now, back your air screws out 1 more full turn and go for a ride and see if that cleans it up. If not say so here.

 

Or are you saying it was fine until you put a new filter on and took the air lid off?

I needed to go down to 240 mains prior to the airfilter and lid removal. But instead of going to buy 240 mains just to get through the weekend I decided I will just put my new airfilter in and use the jets I already paid money for (250-290)

 

It is just boggy in general, I give it gas then bogs and kicks in but it just feels sluggish overall. I only have the airscrew out 1 turn, so I feel like either that is the problem or I need to up the jet one more.

I put 260 jets in today and it ran a little bit better than yesterday with the 250s, but while I was riding I pulled the choke and it ran for a bit, and didn't bog down so I pushed it back in and kept riding. It then started bogging down so I put it in 1st and pulled the clutch in. I went to rev it up and it bogged down and died.

 

I then started adjusting my air screws from 0 turns out to 2 turns out and nothing happened so I got my airbox lid and did the same and it started up but when I gave it gas it bogged down again. Can someone please tell me if my jets are too small or too big, and what my next steps should be to get closer to fixing this problem!?

 

Thanks

Put the 290s in, middle clip needle, 1.5 turns out.

 

Here's the results:

1. Rpms were high again, turned the air screw in .5 and it went down but is still pretty high.

2. Was bogged down at the beginning of each gear, and starting off.

3. Choke test in 1st gear and it bogged rather quickly.

4. 3rd gear Powerband was a bit delayed, I went into 4th and pulled the clutch in soon after and the rpms were staying high and slowly coming back down.

 

Overall: Much better than the 260's but not perfect. You can absolutely hear the gas just pouring into the carbs lol, it is soo much louder with the airbox lid off. It just sounds like I am going to be going to the gas station real soon everytime I give half throttle.

leave the 290s richen the needle up all the way and close the air screw see if it helps
