Race Seven 2010 - Simple Things
Track F
Following the last practice session where I could not turn right, I went back and had a thought about it, decided best way is to align the front of the kart. So the first thing when I reached the track is to get Jason to align the front using the Sniper Alignment Tool. Found that the camber and toe is completely out for the left of the kart.
With that done, I changed the front tires to a pair of lightly used MG Yellow bought off Jon, but found out I did not have a race at all.
During qualifying, found the kart was bogging down at all the low speed corners, but it was kind of on and off and knowing my spark plugs are getting old, I changed that once back into the pit. As qualifying was on a wet track, and it started raining more, I did not go out for more testing. My best timing of 1:05 was nearly 6 seconds off pole.
Come Heat 1, I went out and suffered the same situation, but I did finish the heat. Back to the pit, I mentioned it to Jason, and we checked the Power Valve. Found that the gasket is covering the small hole which is meant for exhausting the gases from the Power Valve. That must have happened as I had cleaned the Power Valve just before Qualifying. With the hole covered, the PV is not able to close, and my low end suffered. Graeme mentioned, simple things, and very true. A simple gasket installed wrongly ruined my race. And why did I not realize it sooner? Anyway, with the rain pouring down and no wet tires, I skipped Heat 2. So it turned out I did not have a race at all.
Just in case any reader is wondering why this is race 7. This is race 7 on the calendar, just that I don't have enough funds to join all of the races.

Turning Right
Today, had to pick up Jon at 6:30 am in the morning, that means waking up at 6am to drive from Jurong to his place. But at least I have company this time going to JB rather than the radio for a change.
This practice, I have bought along the repaired cable for the magnetic sensor used for timing. It was ripped out during my bad shunt a while back. The previous trip, the cable did not work due to it not being grounded, this time, it WORKS! Now I have timing, and I can see how I am doing. Thanks to Karen for getting the cable repaired! That saved me around SGD35 before shipping.
It started raining lightly just as I was putting my helmet on. But it was very brief, and I waited only 10minutes for it to clear and the sky remained overcast and the temperature cool for the remaining session.
My timing as ok for the first session, I am not sure how the cool temperature is affecting my engine as I do not have a temperature sensor. That sensor is out of order for a year now.
On the second session, I found turning right a problem, especially on the downhill and the corner before the pit. I guess after the timing i posted on the first session above, the tires is starting to give me issues. Talking to Jason, he suggested that I narrow the front wheels. That I did, and I found it has gotten worst instead. So he next suggested that I remove the front torsion bar, which was removed, but I did not test as I decided to call it a day as we were running out of petrol.
There is a post on this on Jon's blog titled Wrong Can Be Good. Where he suggested that I have hardly done any setup changes to my kart. I have rebutted this before, saying I need to be consistent with my driving first, then setup change second. Also, I am starting to realize I am a driver that forces the kart to work, so much so that I am insensitive to the kart not behaving as it should. This I have to improve, else I will never get the maximum out of the kart.
Recently, in an article, there is a comparison between Senna and Mansel when they were teammates and Button and Lewis where they are now teammates. The comparison was their driving style, one likes the car to be setup nicely where the other do not mind the car sliding round a little. We are not world champions, but i think the comparison may be the same for me and Jon.

Race Five 2010
Track B
Installed the new MG Yellow I bought off Benz and qualified 6th.
Before the start of Heat 1, I visualized how I am going to start and I did exactly that, just that it was a false start, the green flag did not drop. On the second try, I bumped into the kart in front just at the last hairpin before the start and finish line and my kart stalled. Since my starter is not working, I was stranded, by the time my kart was started using the external starter, I was already 1 lap behind.
Heat 2, I started from the back and had the best race of my life so far. At the first corner, I was up two position, then I left just enough room for Leo to squeeze through on the right, and found myself trapped between 2 karts, and Leo came in and hit my front right tire, causing me to lose speed and drop 1 position.
After that, it was a blur, I was overtaking karts after karts, and not even knowing who i was overtaking, I was just concentrating very hard on overtaking. Once a space is created, I just went for it, no hesitation at all. Out of 13 racers on that day, I finished the heat 6th. I have already caught up with Jon who is 5th, but found my tires have overheated and just could no longer find the pace to overtake. Setting the kart up with very high tire pressure to have early performance, I am paying for it near the end of the race. Talking to Jon, he is right in a sense, I could have easily overtaken the guys at the back with a less aggressive pressure setting. But its a great experience, just wished I could have overtaken Jon, heehee.

It Rains!
Got my magnetic sensor cable back from a friend, and was really hoping that it works so that I can start to do some practicing. But it did work at all. Louis troubleshoot it and found that the cables are not grounded. Hopefully, it is still a cable issue and not a head unit problem. I really need to know my timing, else practising is quite useless.
Luckily, it rained.
Once the rain stopped and the sun popped out, I was already in my kart and headed straight out. Have not drove in the wet for ages. Really had fun, and only spun once. Maybe I was being too careful with the throttling, braking was find as I was braking earlier to prevent the rear wheels from locking. But with the sun being that strong and puddles of water in most sections, the track turned into a dry, semi-dry and water-logged track. At my corner(180R), you can even see the mist from the evaporating water. Trully appreciate the difficulties in driving in such conditions, with the conditions changing with every single lap.
Front tires was peeling off in this session, once I could not get the front to turn in without wrestling the kart, I decided to stop.

Impromptu Race
Supposed to be practise day. But turned into a 2 Heats impromtu race of 10 laps each and I dont feel I accomplished much except to get some race craft experience.
First Heat started from pole as it was decided by birthday months. Finished 2nd after being overtaken by Leo and he pulled away easily.
Took out my magnetic sensor cable to see if I can make a new one in SG rather than buy one which is quite expensive.
And the kart cannot be started from the push button. Need to be cranked up. Looks like I would need to spend more $ again.
