when i had a DR.D slipon 11.5 wiseco piston and HRC cam i ran a 9.40 @ 71mph

after alots of changes it's around 7.50 at 85mph

stock would be around 9.60's

I wanna say Twisted's 04 ran 8.50's in the 1/8. Pretty much stock also. I will get him to post times and mods. I believe he had a pipe and like 22" rear tires

i know a HRC 450r runs 9.5 in the 1/8th. stock 400ex is 10.4 in the 1/8th
