Stock carb mod

ya I like it when the hole comes out where the slide seats.My yellow bike siezed at the race my friend Tory was rid'n it,he said he had 2 peddle it back off the track,I thought it was the clutch but when I tore it down,the main bearing on the crank is like gummed up I'll pull it apart n see, I had a new motor 2 put in and it seems fine,low compreshion though even with the slant head,I took the new one apart before I ran it the cylinder looked good,I ran the hone through it the ports looked good we'll c how it likes that big carb it seeme to run fine.I'm guna try that slide modif.on the blue one.
