WB E-series ?

[400EXPILOT]

Just put on the E- series slipon on a few days ago and what a nice power change but I did not re-jet and it seems to run great.
Is that normal to run that good with out rejeting ?

PS : 12 disks and a K/N Filter

You need to do a plug check to see if your jetting is ok. Cause it will run it's arse off when the jetting is lean until it burns it up:ermm:

155 will be very close!

i just put one on a few weeks ago - it says it comes with the right amount of disks installed to work best with stock jetting and aftermarket arifilter in the booklet. i did not re-jet and it has been running fine for me and have two races on it so far.

I run a 165 but I have an open airbox and a modded head pipe.

Depends how the machine was running before. If it ran rich before it should be fine now. When I installed new reeds and pipe/silencer on my 125, I actually had to lean it out.
