p-38 lightening

has anyone tried this mod?how well does it work?i have 99 wr400.

I tried it on my WR250 a couple years ago. I didn't think it did anything, but maybe other tuning was my problem.

You might just want to try putting a slug in the bottom of the recess to keep the plunger from sitting low in the stroke.
