“What you could do is close your eyes and blow in it”
Next line: “you probably don’t want to do that”
Had me weak🤣
I’m happy I didn’t get any in my eyes 😆
iv never seen anyone drill out the valve guides ? let me know how that works out.
+1 on that
It works great I do it often, you can also leave them if you want
It Bubba from Mesa Mini’s by the way! I’ll be posting hella mini bike videos soon!
I gotta check you out man
I don’t think the Christmas music was loud enough
Did you have to rejet your carb after this ?
Re jet no, i was already on a 125
And after enlarging that exh port that much your gonna bolt on some small diameter header. it doesnt make much sense to open up the runner that much.
You need to port match the header as well
Do you recommend doing this on a tillotson hemi head?
It’s free power! Yes I recommend it
Just don't hog it, make channels with a rasp. Take the sharp edges and hard turns down and port match it. That's the best you are going to get without a dyno or flow bench.
@@thewhiteeazye2728how do you port match
U need a flow bench, then u,ll see how u killed ur flow on porting,took out too much Bud,
I gained 300rpm and 3mph
More air flow but less velocity
But yeah a flow bench would help
