Would like to crack a 9

[Streeter.]

Hey guys, I have an 08 Busa with a yoshi R-77 full system and a K&N filter as the only mods.

I managed a 9.79@150mph out of my K8 mate with the same two mods as yours at stock height, except I was using the M4 system and not the yoshi.

With 2 up on rear (45), BTL modded and a quickshifter added I got a best of 9.69@152mph at stock height.

I weigh 86kgs race ready.

A heavier person at "stock height" has no real less advantage. Maybe some disadvantage to a degree slammed.

They are definately capable with some practice for sure.

Good luck with it.
