wet pipe question

[Johnny2722]

I just put a factory wet pipe on my sxr and I love it, but I cant do tail stands anymore what gives?

 

[Johnny2722]

I forgot to say that it bogs and just loses power when I try to do them

 

[WaveDemon]

you're carb jetting is off.

 

[Johnny2722]

that sucks i put in the jets that came with the pipe

thinking that may be a pop off problem. try changing springs. think thats how i fixed the same problem on a kawi last year

I went through these probs last summer with my wet pipe. I have all my settings written down. I went with way different pop off settings and way different jetting then what FP suggested. If you need any help feel free to call me. My set up isn't perfect yet, but it it leaps and bounds better than it was with the FP settings.

Alright I'm a do it your selfer and this is my first time really playing with carbs! I know how to re-jet them and mess with the high speed and low speed screws but I have no idea what pop off is so a little help please. My friends own a dirt bike shop in town so if its something that I think I'll need help with I can go talk to them but I would like to do it myself. So any input would be much appreciated!

I used FP settings and jets with no problems, but I have a 2003. (You do need to change the pop off if you havent. I believe the numbers are in the directions)

My ski is also a 2003. I got myself a pop off pump/gauge and it was the best thing I ever did. Just getting your carbs to pop off at the same pressure makes a big diff. For my ski I found the FP setting to be a bit rich.

First step is to read and understand the Mikuni manual then it will all make sense.

thanks mike, hopefully that will make life easier. cd155mx I would still like to know what you did to solve the problem you can e-mail me at johnnyschneider2722@yahoo.com when you find the stuff you said you had written down

 

[Johnny2722]

Alright I read the manual and I understand how to change the pop off, and from what it says it sounds like my pop off is too high. So that means I should use a weaker arm spring right?

 

[brentR]

correct.

 

[Johnny2722]

So my plan is to go down one size at a time until it feels right. I checked the instructions that came with the pipe again they don't mention changing the pop off, heres the jetting specs that they give you.




2003 and 2004 SX-R 800 Wet Pipe Jetting Specifications
Main jet: 152.5 front, 152.5 rear
Pilot Jet: 80
High-speed screw: 1/2 turn out from closed

Or you can simply cut yours to your desired popoff. It doesn't take much.
