In this thread you can post anything you have done to your kart or racing program or just want to share a hack that you have. Share, share, share as this could be an entertaining as well as informative thread for new and experienced kart racers.

Today I uploaded some racing videos from CKRC Race 3 and 4.

Great topic John, this will likely turn into a somewhat useful guide for people. I’ll post some of the tricks I’ve picked up on over the years when I can properly document them.

On the weekend, I straightened 6 steering shafts and 2 tie rods.
Today I worked on my shifter: I changed front and rear brake pads, changed the transmission fluid and modified my radiator blocker so that it had more rotation to expose the radiator. Tomorrow I have to mount new tires for the weekend and change the oil in the Briggs kart and clean it.

Got questions about race prep, let me know.

I measured things

I found a trick recently to cleaning black marks off the decals. It is not without risk!!!

If you start by removing the thick black marks with a scraper until its mostly gone, then take PVC primer and rub the applicator it on a small area at a time, then IMMEDIATELY wipe all the primer off with a clean rag. The Primer will take the black marks off super quick. If it is left on too long it will soften your decals tho. Be careful.

As good as Lane's previous comment is, lazy old men like me get tired of any form of physical work.
You've paid good money for decals and if you're tired of removing the black tire marks that cover your side pods, put on a 3M film/wrap.
It's easy to apply and quite cheap as well.
When it gets covered in black marks, simply heat it up with a heat gun and remove.
Then apply a new clear film strip where the old one was.

I 3D printed new hinges for my race cooler.

Today I worked on my shifter kart. I fixed a loose shift lever linkage by replacing a ball joint. I sourced a water leak on the motor which was a loose threaded lower insert on the transfer passage from cylinder to the case. I removed the seat from the kart in anticipation of trying a stiffer style seat and I removed the motor mount plate and cleaned the lower fins of the motor of dirt, grease and rubber build-up which should help with cooling.

I also 3d printed a flexible latch out of TPU for the cooler that broke years ago. [attachment=2]

Not to "One up" Lane or Steve on the removal of Tire marks, but I found this little tasty nugget while searching for magic erasers at Princess auto to remove the leftover decal glue on a front bumper. Worked so well on the glue I thought I would try it on the rubber. Literally an eraser for your marks, cleans grease, bug guts (assuming gopher remains as well). No Liquid cleaners, no elbow grease just a drill and 10 seconds time. Does not burn through decal and makes it look brand new. Highly recommend everybody to have one in the trailer.
