Just fired my sled up and took it for a short ride after rebuild...

So I jetted per SLP's recommendations and I just had a quick question.

My EGT guage was showing 8 on the left side and 4 on the right side. Is it normal for these twins to be unbalanced on the EGT guage? Sled rips, but just want to make sure I don't mess anything up since I just rebuild it last year and this is the first time I have been able to really ride the machine since it was rebuilt. I didn't really ride it hard or WOT, just around the block for about 10 minutes or so. Seemed around 400-600 at idle.

2001 RMK, SLP twins, ported and polished.

Thanks!

It feels a little sluggish down low too... I know with twins they can do that, but just wanted to make sure I don't need to switch jets up another size since one side is showing a lower EGT which I assume means it's running lean.

My sled does have staggered main jetting per SLP's recommendation. One side is 20 higher than the other.

I think I got it fellas. I was running 470 mains. Switched them to 500's and the sled is running MUCH better. No more bog down low.

I used that as a guide. I run around 300-500 elevation and 0-14 degrees on average for temp.

higher EGT number is lean, lower or cold number is rich .
keep it below 1200 and you should be ok
mid throttle cruse @ 900 to 1000 deg is good .
always DBL check your plug reading ..
