Michaels Second Race in Kid Kart

Image
  Getting everything prepared to load in the Infiniti for the next day Michael's second race with Tri- C Karters was on August 7th, 2021.  I had some problems with the kart and clutch, so even though it was a night race, we went a bit early to do some testing before racing.  We did one test session, and then decided to just chill until the evening racing.  The track format was slightly different than the configuration we normally use.  The Ryobi 18 volt cooler/blower. It moves a little bit of air, but you have to be sitting right next to it to really feel it.  Michaels kart now decorated with stickers Our setup in the upper paddock. I would rather be in the lower paddock. It can be a bit of a walk pushing the kart Michael at Marlees Taqueria The kart kept tossing the springs out of the clutch. I had the engine/clutch off the kart three times, trying to get it to work. I really struggled with it. One time I worked to get it fixed. Tested it in the pits, then it failed on the grid. I

July 18 at Adams Motorsports Park

Image
  July 18th, Sunday seemed like a good day to go back to Adams.  I did a little bit of work to the kart, and it was a time to try it out again.  Mike, Chuck and Odi all came out with their kids.  Michaels kart also has the sticker upgrades. It was going to be another hot day, 99 is what it said, so we knew it was probably going to be an early day.  Michaels kart didn't seem to be that happy. I ended up cleaning the carb, and it was better, but still seemed a bit off. That carb is irritating me. Its the 2nd carb, I am leaving it drained. I tried some pure 92 no ethanol fuel. It still seems to be getting clogged up. Mike also speculated that I might have the oil level too high, and so that is acting as a bit of a governor. I drained some oil out of it, and it seemed to get some revs, but I still think its off.  It seemed to be missing a few mph in a straight line.  So Michael and Kai did come together at one point.  Michael was passing on the front straight section, basically right i

July 2nd at Adams Motorsports Park - Topkart

Image
Michael sitting in front of the Ryobi 18v cooler fan Decided to go to the kart track before the 4th of July trip.  I just installed the Aim Mychron 5 dash onto the kart, and I wanted to try that out. Michael seems to be enjoying driving the kart, so we need to get some data to see where we are.   I knew it was going to be hot. Adams is running night practice on Tuesday and Thursday, but honestly the temperature difference night to early in the morning is about the same.  So decided to go to the track on July 2nd, Friday.  Stay until we melted.  Some learning moments in that video.  Our setup at the track. You need a tent/shade out in Riverside.  We were the only ones at the track for a few hours. Michael went out and drove around for a bit.  Then after a few hours, Ivan and Adam came to the track. Adams kart just got a Honda 50 on it, and it was pretty healthy and quick.  Best lap was a 1:12.1 AIM Racestudio Analysis However, the kart kept tossing the chain.  Fun with use

5th Birthday Weekend

Image
  Eating cupcakes at his 5th Birthday Michaels 5th Birthday was on June 4th. Officially he is old enough to race his kart, although he may have already done one race.  We went out to Adams Kart Track again. Back to back weekends may be a bit much, but it was a good fun, full weekend.  This time I ran the GoPro Hero 7 without the waterproof case, so you can hear the engine, and throttle pickup. 

Adams Kart Track May 29, 2021

  Michael getting ready to go on track On May 29th 2021, we went to Adams Kart Track, and met up with several friends. This time, Mike Kojima brought out a spare kart, so I got a chance to drive on track.  The kids had a lot of fun driving around.    I had the GoPro Hero 7   in a waterproof case, but I should have just had it in an open case. You can't hear the engine, just the noise from the track transmitted through the chassis.  Waving Checkered Flag. Kai beside Michael Getting closer 33 mph Just a bumper now Passed at the line The Topkart with the Honda GHX50 engine isn't as fast in a straight line as the Comer 2 stroke engine. I don't know how many hours are on Michaels engine, but at some point, I will have to get a new one. They don't reseal/rebuild the engines through HPD, you just buy a new one.   

Duneracer and Testing the GoPro Hero 7 Black

Image
  The Duneracer is a Power Wheels alley find that didn't work. After messing around with the shifter, adding a battery connector, and eventually changing the motors and gearboxes, Michael has some fun in it.  It has the ability to run the 19.2 volt Craftsman batteries , or the 40 volt Ryobi battery .  The Duneracer has plastic wheels, so it mostly just spins the tires. Spinning the tires saves the gearboxes.  The GoPro Hero 7 can show speed and g forces, so also testing that out here. Will be interesting to get it on the Topkart.  According to GoPro and Dragy, the Duneracer does about 7-8 mph. Although downhill maybe 9 mph.  I used a Deutsch connector, but I will probably change it to an Anderson connector 40 volt Ryobi setup.  This was an old charger for the Craftsman 19.2 batteries . This doesn't positively lock on, but it works ok. Not great, just OK
