, 1st CCS Weekend at Loudon
Coming off the Moto-ST race one of the things we needed to improve
on was vehicle weight. We started off looking at each section of
the bike and for the time being we decided to focus on the bike’s
primary and tail section. First off we decided to remove the starter
from the bike (8 lbs), which required coming up with a way to get
the motor going. To solve the problem, we took a control stock go
kart motor from our old karting days and developed a Moto-GP style
starting kart. (See a short video of the J.E.T.
In addition to removing the starter,
we did some research and got hooked up with two companies Pickarski
Racing Components and Evolution Industries USA. Pickarski Racing
Components makes high performance light weight low output charging
systems for Buells and Evolution Industries USA makes aluminum crankshaft
sprockets and clutch baskets for Buells and Sportsters. Pickarski’s
stator and rotor weighs aprx. 5 pounds less than the stock components.
Evolution’s aluminum crankshaft sprocket weighs 1 pound and
the clutch basket without the ring gear weighs aprx. 8 pounds. With
the change in these components we have been able to shave off 11
pounds in the primary alone. We are trying to help both companies
as much as we can with the development of their products.
In the tail section, we removed the stock plastic trunk kit (under-fender
guard). We chopped the sub frame in half and welded in a brace for
the tail section. We also re-welded the battery box for a YUASA
YTX-07A battery (4 lb weight reduction in battery change). Total
tail section weight savings was 3 1⁄2 lbs and the bike now
weighs 382 lbs dry.
For the sake of time and desire to
improve as a rider we decided to leave the same engine in the bike
that we ran at the Moto-ST race in Daytona. We were confident that
the J.E.T. modified XB9R motor would still be race-able even though
it had over 5 hrs of race/practice time
on it, and we were right.
We arrived at Loudon for Thursday afternoon practice. We were only
able to get three sessions in because a Jap bike puked oil all throughout
the entire track. We were able to get within 2 1⁄2 seconds
of our last years best time which was with an XB12 engine (J.E.T.
modified of course) and old practice/race tires from Daytona.
Race Day #1:
Our first race of the day was an Expert GTL race. We were still
on an old set of Pirelli DOTs, we got a good start to the race,
I was running in the top ten, I was holding my own and then the
race was red flagged half way in. On the re-start I didn’t
get a good launch off the line and probably ended the first lap
in about fifteenth. I ended up finishing 11th with a fastest lap
The next race was the Expert Thunderbike race. I got a good start
for the race and finished 5th for the first two laps and then was
red flagged again. On the re-start again I didn’t get a good
start. The Evolution Industries USA clutch works great, but it has
taken me a little while to get over how grabby the stock clutch
was. I ended up finishing 7th. We mounted up Pirelli DOTs for this
The next race was the Expert Light Weight Grand Prix race. I got
a really good start and was in the top 5 for probably the first
4 laps of the race and I ended up finishing 6th. Saturday I was
able to do a little thinking about what areas of the track I needed
to work on and I woke up Sunday morning ready to ride hard in Expert
Supertwins and the Expert Light Weight Superbike race.
Race Day #2:
Sunday morning I woke up to a wet, but drying track. Our practice
session was not fully wet so I went out on DOTs just to get the
feel of them on a slick track. My first race of the day was Expert
Supertwins. I practiced the starts a couple of times, had them nailed
and got a great start for the race. I got into the first corner
in 5th place after starting 8th. An Aprilia Mile crashed in turn
three and bumped me up to fourth behind a 1098 and an SV650. I made
quick work of the SV650 and made off for the 1098. I was able to
catch the guy on the 1098 and pass him coming onto of the front
straightaway a couple of times, but his 45 HP advantage would get
him right back by me coming into the first turn. A different guy
on another Aprilia Mile also passed me due to his HP advantage and
I ended up finishing the race in 4th. The race to follow was Expert
Light Weight Superbike. I started on the inside third row behind
Rick Doucette, nailed the start and come out of turn 2 in fourth
place. I was able to pass Doucette coming into turn three for 3rd
place. As the race progressed I was able
to make good use of lapped traffic and finished the race in third
place, attaining my first podium finish as an Expert.
The Evolution Industries clutch and sprocket worked perfect. With
the weight reduction on the primary components I noticed an improvement
in acceleration. The clutch is a very smooth unit. The Pickarski
charging system worked flawlessly. It was able to maintain battery
voltage all weekend. It is a real charging system for real race
bikes not like the overweight TC/Sportster unit.
All in all, it was a great first
weekend at Loudon and after a few adjustments we are looking forward
to the next weekend at the track (5/12-13).
