98 sx 700 power inc pipe jetting question

[srxman72]

Hi, I found in the tech section that for this sled with PI pipes the main jets should be 145 across. Is that for end or center dumps? I need the info for the end dumps. Also is it simply changing the main jet, I would think some pilot jet and air screw changes would be needed as well. Conditions are 0 to 2000ft and temps -10 to 40f. Thanks

I found this setup from a gytr setup page. It was photocopied by turk and its hard to read but this is what I found. I still don't know if this is for end or center dumps however this set up page was made in 97 or 98 so I think its the end dumps. If someone can confirm this that would be great. Thanks

pilot-55
fuel screw- 1.5
main jet- 150
clip position- pto#3, center#4, mag#3

This is for 0 to 3000ft

That sounds right for the end dumps, I ran something close to that on my old sx 700. I had a 50 pilot though but I did have some idle hang.

Well I read further into the thread and those specs are for the gytr pipes made by bender. Im sure they are close to the power inc's though.
