It has been awhile since i have raced a motorcycle, but i think i am going to start again, nothing pro or anything, just for fun.
My main motivation for this was visiting the warrior forum and it so happens one of the guys races at what used to be my local track . any pointers from you pros that have been racing the V-rod ?
Here are his best times, so he claims
"My best run yet 1.008 R/T
1.849 60 ft
5.202 330 ft
8.064 1/8 th mile @ 86.27 mph
10.42 1000 ft @ 94.95 mph
1000 ft track"

Ya start of by Practicing Your Reaction Times!I run a Pro".400" Tree so I'm no Help for You,but Kevin is a Sportsman".500"tree Pro!Start there before you want to race anybody! ;)

Thanks Kaz, maybe kev will chime in. I have a old drag bike and a pro street car but it has been a long time for me to hit the track..i think i am going to go out there sat night and practice on the Rod...i think my main concern is launching.

I know that most cruisers have more torque than me and that really counts on such a short track ,i think i will start off with some soft launches and go from there till i can get the feel for it.

Start soft... keep working it and you'll be hard pulling in no time!

er... um.... yeah, that's it! ROFL!

GET YOUR TIRE PRESSURE FIGURED OUT FIRST!Do a Good second gear Burn out just pass the water"So Tire is not in the water"!Try 7000 rpm a agressively Feed the Clutch.Don't Pop it but let it out Fast!If the Tracks good you should Bog on the Launch so be as High RPM as possible with out Spinning!Work up or down on your RPM Launch till you start repeating or going Slower then you have a Good Base Line.Only change 1 thing at a Time now"Shift RPM,Tire Pressure,Air Box Lid On/Off,etc,etc....


P.S Take Notes !I USE A RACERS LOG BOOK! :thumb:

Sorry... I couldn't resist ;)

Seriously tho... I have a launch question, too:

For a roadrace start, I have found that feathering the throttle within a given RPM range has given me a better (smoother) launch than just holding steady at X grand and feeding the clutch. I'm guessing that the downside of this is the possibility of "leaving" while the throttle is momentarily in a position of deceleration. I'm hoping to try this technique at the dragstrip tomorrow (providing it doesn't rain out AGAIN).

Your thoughts?

My guess is that feathering the throttle on launch is causing more clutch slip, which will be smoother, just at the expense of the clutch.

Best thing to do is get the clutch to fully engage as fast as possible. I would rather spin the tire a little (likely with street tires) than burn out my clutch.

Yeah, Goatman... the more I think about it, I realize that the situations are really "apples-to-oranges". The added wheelbase, weight and available traction allow for a lot quicker delivery of power to the rear wheel.

BIG DIFFERENCE between the two! ;)

Aye... if I was to run the Tiller up to 7 grand and dump the clutch, she'd be flyin' backwards over my head!

So much for THAT idea!

Good link - I am running between mtgs but I will get back
Set up - 28 tooth plus shift light and teather kill switch - can be bought at Pingel.com
Not necassary to race but pretty much required to win.
Tire set up 30lbs @ back - I do first gear burn outs as opposed to Kaz's style in second.
Launch 6,000 RPM and slide/dump clutch - on third yellow - No slack in clutch - held right at the point that it is not dragging - I actually have a bolt in my hand grip that works like a set screw for exact position. Shift light @ 8625 w/Rev limiter @ 9,400 for head room - Rev limiter encounters lose races. I was power shifting - set screw makes it real fast - electric shift currently makes faster - I am using for 2-3-4 - First to second still power shift. 1.80 60s common - best 1.75 w/7.5 in the eigths @ 95mph - best 1/4 @ 11.59 @ 114.89 about 3,000 adj altitude - must go - IU will do better later.

1000' is about 2.0 seconds shy of quarter mile time - @12.00 seconds and 1.96 or 1.97
towards mid eleven ET therefore 9.7 second 1000' times

OK - a few more comments- VROD clutch is damn near impossible to feather because it has no feel - at least not to my hand - so launch tends to be a fairly aggressive dropping of the clutch - stock bike sets into a a bit of a bogg - nice feeling on a Saturday night - almost impossible to break a heated up stock donlop loose and slim and none that it picks up front wheel. Roll on to full throttle as clutch is being released - enjoy the moment and prepare for fairly aggressive acceletration. - Shifting in about 2.7 seconds. I set up with my feet forward near pegs - and just lift up on launch - feet are up almost immediately (at least in the pictures - it all happens kind of quick - not thinking about it. KB - those crouct rockets with tiny wheel bases are like fly swatters - but your previous start soft comment still confusing me -

Hey shawn - I am glad to hear that you are interested in racing - sorry for the abrubt descriptions above - I was just trying to do a fast brain dump within a short time window that I had to write. I think that you will have a great time racing - The VROD ois a great bracket/ET race bike, very consistant, reliable and easy to ride - and exciting. Now you know that if you go back to the track it is a bit addictive....KSP

From one to another... be careful, it's addicting as all heck :-) I went out to the track a couple of times and caught the bug fast! It also gets expensive really fast too! From my first time out, here was my best time out of 4.

R/T - .112
60' - 1.869
330 - 4.961
1/8 - 7.616
mph - 92.03
1000 - 10.004
1/4 - 12.066
mph - 108.33

I've just been chomping at the bit to go back out there again. Just had to wait until I had all my upgrades completed. Yeah, I'm a warrior but that doesn't stop me from talking to you! lol You're in for one heck of a ride brother!

By the look of your avatar you have a serious torque problem. Thats why most of us like to keep ours in the 80-90 ft.lb. range. :rolleyes: Seriously, I do kinda miss those wheelies from my Buell.

That was actually my very first run ever on a track and I was extremely nervous/anxious/excited at the same time and over-revved at the line. I ended up launching somewhere around 4K and that was the result. Still won the race though lol

Hey chris i have a drag bike (honda RC ) but i have not raced it in a LONG time...i also have a pro street bird ..but i have not been to the track in years...any pointers?

I appreciate all input from a racers standpoint.

Find the book "When the light turns green" by Tom Murphy. :-) It has a lot of good tips in there for preparing yourself to race and also how to build your bike up as well.
I've just started racing myself and in no way do I feel qualified to give advice! I ask a lot of questions and read everything I can find. I focus more on getting myself ready to race rather than the bike. The bike is mechanical - the mind is another animal itself. lol I truly wish I could be more help to you.
Kevin is giving some great tips and especially since it is more focused on your bike. Our bikes react differently and my launch rpm is a whole lot different from yours. You have to remember the Warrior rev limiter (with a modded bike) kicks in around 55-56K rpm where I'm pretty sure yours goes much higher. I have to launch around 3K otherwise I go vertical.
