1/8 mile probably 7.2 7.4 with your weight with a 1.8 60 ft

Mid to low 7's if you've got average drag race skills.

High 6's if you're GOOD.

took the bike to the track last week and mustard a 1.79 60ft and pulled off a 7.44 @101mph, wantin to get my 60ft in the low 1.7's or high 1.6's, and be able to run low 7's or high 6's before i do any more power mods or extend the arm, also i was leavin at 8rpm

1.7x 60's are pretty respectable on a stock wb bike. Not bad at all.

With that 60ft though, you ought to be getting a little better et. I'm 60 ft-ing 1.95+'s, and running 7.5x's. Granted, it's two completely different bikes, but from my experience, my SV1k is running right on par with the current 600's.

whats your weight and gearing, i feel like i need more gearing, what do u guys think

[396d1ss]

6'' extensions and strap your bike and practice that 60 ft and i see 6.9's -7.1's

[396d1ss]

also your mph seems a bit low are you letting off the throttle during shifts?? if you havent yet look into the reverse shifter 1 up 5 down it helps your balance leaving t he line alot being able to hold your left leg out longer

i have a front end strap and i strap it when im at the track with the rear lowered 2 inches, runnin a dunlop street tire on the rear for now, have looked at extensions for my bike but would like to get in the 7.0 -7.2 bracket before i extend the arm, also do u think a airshifter will do me more good than extensions or 1 is good as the other

whats a reverse shifter, that might be what i need to get or do to get better times at the track, im clutchless shifting from 1st thru 3rd and blippin the throttle when shifting

[768-Ryda]

do u think if i raise my rpm up to 10k and try leavin the line that will help my 60ft, mph & ET.

on a stock shifter after you leave the line you have to tuck your foot under the shifter and pull up, which only gives you limited time and can throw your balance off from leaving HARD because you need to get your foot tucked in. On a reverse shifter after you leave the line all of your gears are down so you put your foot on top of the shifter and you can hold your left leg out and leave harder. Personally I recommend after you launch do not let off the throttle PERIOD...... powershift with the clutch fast DO NOT let off the throttle... 10k sounds to high.... even at a 10k launch how long will you be slipping your clutch versus leaving at 6500 with not alot of slip.... you just dont want it to bog.... IMO dunlops are decent only if you are not spinning...I have had alot better 60fts with power pilots.... I would get extensions and learn how to leave hard before i got an air shifter.
