Not new

Hello everyone, I’ve been gone for about 6 years ( I couldn’t remember my old password). I had an 04 919, she was my baby. I got her down to a 10.98 out at the strip. Well traded it and my shadow in on a 2010 Sabre. Hated that bike and sold it off. After about 6 years I had the itch an picked up a 2011 speed triple. I put 600mi on her going up to Milwaukee for the 115th Harley anniversary. Nobody spit on it and had a blast, glad to be back on two wheels.

It’s been a while, but they’re pretty comparable. We’ll see what I can get out of her in a few weeks on the strip. My 919 had 120whp after tuning, the 1050 stock is about 116whp.

Can you tell me what you did to achieve the time you did? I'm taking my stock 919 (17/44 conversion) with 50k miles to the strip for the first time and hoping to break into the 10s.

Man, that was about 7 years ago. Let’s see:

Something called the “air box mod”
Flapper mod
Baffle removed stock exhaust
K&N
PC3
15psi rear tire pressure
Front end tie down strap
Hotter spark plugs
Full Barnett clutch kit (blew out my old one on the track)
Launched @5k slipped the clutch carrying the front past 60’.
I only made 1 pass after the clutch 10.98.

My very first time out was a 11.78, I got it down to 11.5’s before I did everything. Ran consistent 11.1s on cool nights. That 10 was a perfect scenario for me.

That was a slow run. No wheel up.

I wonder how much difference each of those made. I thought colder plugs were better for performance engines.

I can see the PCIII, K&N and maybe the baffles.

I wonder how much tire spin you were getting and did the 15psi help.

Nice to know you can hit the 10's without digging into the engine or even replacing the exhaust.

Anyone have one of those calculators that can tell how much HP you have based on weight and time?

Edit: According to this site: https://www.ajdesigner.com/fl_horsep...apsed_time.php

If you weigh 215 (700 total) it would be 104.5 HP
If you weigh 165 (650 total) it would be 97 HP


That seems about right, if not a bit low. I thought they were 105 ish in stock trim, I guess not.

Before tuning I believe I made 89 or 98whp, after it was done I made 120whp. No spinning the tire. If you want a good launch I found slipping the clutch and keeping it in the sweat spot worked for me. Was I doing it wrong? Probably, but it’s better than flipping it over ( can’t ride wheelies for sh!t). That run was also at night with a sticky track and 67 degrees. I remember seeing on here some guy lay down a 10 on a bone stock bike, but I don’t remember seeing a time slip.

Also I remember letting out the clutch just enough to get the slack out of the chain so as to not shock the driveline. I beat up my old clutch at the track. Probably had close to 100 runs before it went. The bike had about 10k miles on it before I started racing.

I've got easily more than 100 WOT launches on it, a bunch of track days and 50k miles on it and i'm shocked the clutch is doing fine so far. I feel like my bike is a little bit down on power from when it was new but I'm still hoping for a good run. I'm curious to know how you got to 120 WHP, being that I only heard of one guy getting there with a bunch of mods, including custom ported heads and different cams. I'll probably keep street pressures since I doubt traction would ever be an issue in the dry. Do you think that low fuel vs full tank makes a big difference? I think running an empty tank nets roughly a 5% gain in power to weight for someone at my weight. I wonder if dropping all the preload out of the forks to drop the nose of the bike down would help it get off the line without doing a wheelie.

As far as horsepower, that’s what the dyno said. Could be right, could be wrong. I’ve seen guys at my local track use atv ratchet straps to hold the front end down. It’s all trial and error. I raced for a season and a half before I got my 10. If a person was smaller and got off the line perfectly, consistent 10’s could be achievable. I’m 6’ 220 and always tried to have a full tank of 93 when I went out. Weather that helped or hindered I knew I wasn’t going to run out of gas. (Made 17 passes one night). I thought I was king shit until I had my butt handed to me by a 600, it was humbling.
