Hello, been doing some searching on here and keep reading about ported sx motor with piston mod, anyone have any info or pics of this? I haven’t seen an actual pic of what is done to the piston. Thanks
Did this to a lot of 700s back in the day.
Aaen had a stage tuning in an old American snowmobile magazine. Was good info.
I have a spec somewhere. Would have to dig through my old binders.
