You do a burnout in 2nd to get speed at the tire (more 'burn' in the 'burnout').
For a race, start in first. *Feather* the clutch or you'll be on your back after the bike throws you over the license plate.
Once you're off the clutch, don't touch it again until after you hit the traps. Keep your toe pressed against the underside of the shifter. Momentarily twitch off the throttle when it's time to shift, the change in drivetrain load will let your toe shift the bike. Get back on the throttle, drop you toe to "reload" the shifter, then press up again and repeat.
If you are going to drag race a streetbike...find someone locally that will take you under his (or her) wing and go to the track and teach you. It is impossible to teach the nuances of dragging a fast stock wheelbase street bike on the internet....other than the most basic stuff....such as clutch managment is the hard part...and never, ever put a street tire in the water box...burnouts are a no-no unless you are using a drag rated tire like the Shinko 003 or the Mickey Thompson DOT tire...a couple of try hops is all you need...burnouts on most street tires only make smoke, kill the tire and actually cause it to have LESS traction.
Bottom line...find some non-squid serious sportsman racer to show you the ropes...if you lived in Central Florida, I would help...I already have a "student" for this weekend.
Oh...on the burnout thing...2nd gear should work ok....I used to do the burnout in 5th gear...but thats another story....remind me to tell you about it one day
I read somewhere here that the sequence of photos shown above are a H-D tech that took a demo bike out for a spin. I wonder if he lost his job over that?
Yeah the one time I went to the drag strip I got in trouble for doing a burnout. Didn't know I wasn't supposed to... the street cars were, so I did too.
I believe Spidey was working at the dealership at the time.
You are correct that was a porter from American Harley.
That was our second XB, so I threw a race kit on it as we had two more coming and figured that it would be one awesome Demo bike!
So that porter was a friend of the Owners son, a real trouble maker, the porter that is.
Well one Wednesday, a test an tune at that drag strip, I went to grab said XB to have a demo ride.
OK where are the keys?
Go up to the owners son. Hey where are the keys to the XB? Where is the XB?
He didn't know, no one knew.
OK let's wait it out maybe another sales person took it out or is out on a demo and another sales is out with said person....
So while we all asked around we get a call to come into the service dept office.
We head back and get the bad news.
Porter McDumbass took the keys, a dealer tag and headed to Milan with the XB. Paid his 20 bucks to run the test and tune session without asking or telling anyone. Did two runs then his 3rd run the above happened.
He thought he could go, do some runs and come back before anyone found out. SO he comes back in the truck with our driver head hung low.
He got his assed chewed by the owner and to save his job he paid for all damage to the bike.
1st gear alone is fine for the burnout, you do not have enough power to need to put a lot of heat in the tire - it is more to "clean" the tire, a dry hop works just as well but isn't as much fun.
That said, your 1st time I would ride around the water and skip the burnout if you are not used to doing them.
I strongly recommend that you buy a front end strap.
It will make the bike easier to launch, less likely to wheelie and is good for 2 tenths.
Don't worry about cutting a great light your 1st time, concentrate on the launch.
Here's the important part - treat both the clutch and the throttle like rheostats - not like switches!
You need to come in with the throttle as you slip the clutch.
As this is going on you need to get your feet on the pegs because you need 2nd gear real soon!
shift at 6200-6300, no need to go to redline - bump the rev limiter and you have killed any chance of a good number.
Use the clutch for your shifts as you would on the road, but eventually you will want to shift without the clutch by quickly easing off on the throttle, snicking the next gear and back on the throttle.
Have fun, it is addictive because you will convince yourself that you will do better on the next run and the next and the next.....
