There are certainly some great karting products out there but for the budget conscious karter sometimes you need to be innovative.  The biggest issue I found was mastering the technique of changing tires with your bare hands.  I always needed that 3rd hand or more leverage.  Our temperature during racing season in Canada is rarely hot and a warm tire is always easier to change.  What I use is a length of 3/8″ ready rod, 2 flange nuts and 2 pieces of 1″ square aluminum tubing cut to about 4″ long.  I use this contraption to mount the wheel to the work bench via a hole in the work bench.  This way I can get enough leverage to use the techniques you see on most of the tire changing videos.  I have been using this tool I built for over 20 years now.  It is simple, cheap and easy to haul in my toolbox.

For myself, I don’t like using water when mounting a tire as it will cause the tire to heat differently when being used because of the water left inside.  I use Gojo smooth hand cleaner (non-grit) as a tire lube as it evaporates inside the tire.

Sorry for the delayed response. My other computer wouldn’t let me log into the forum.

I found the short intake to add a noticeable amount of power.  I also did the flat top piston and the appropriate head insert.

The front leaning angle that the short intake puts the carb at is awkward and is probably affecting the float height setting and dumping fuel where it can.

I am using the round fuel pump that is seen on most Euro shifter motors.  It has two fuel outlets but I just block one and run one fuel line to the carb.

I run a TM K9B and have switched to the short intake.  The TM K9’s that I have seen had a collar that went on the carburator which then fit into the big carb boot that you describe.  The short intake that I have from Green Flag Racing does not use this collar so I guess yours is missing.  I also run mine with no return line or restriction in the main line but I do put a fuel filter just before the carb that acts also as a reservoir for extra fuel.  The karts that I have used with a return line, we used the screw off top from the top of a spark plug inside the return line to create enough resistance so that more fuel pressure will go to the carb instead of the return line to the tank.

Here is my experience with transmission fluid levels.  I did a rebuild this past winter on my K9B and used this thread as a resource for the amount of transmission fluid to use.  I put in the 500ml and the motor didn’t seem to have the same over rev or mid and top end power.  Spoke to another competitor and Joey from Overdrive and dropped that transmission fluid down to 300ml.  The motor has now come alive on the top end and is very snappy.

Hi Tom,

A Mom in my club bought one of these for her 10 year old son.  When it arrived the sizing was off for him as it was too large.  I ended up buying it from her.  I am 5’9″ 180 lbs and it fit me.  I have been happy with the suit for the most part.  One strange thing with it was the waist belt, which was installed too high on the waistline.  I was able to alter it and the suit has been fine ever since.  These cheap suits work fine but there definitely is a difference for the price that you pay compared to a name brand suit like Sparco or MIR.

The Motard bike club that uses our track has had to quieten their bike exhausts and has used sections of inner tube hose clamped on the end of the exhaust silencer to break up the sound wave.  They have it extended about 6 to 8 inches off the end.  Not pretty but cheap and effective.

Hi Chad,

You can use a set of pin gauges to check all of your jets.  Here is an eBay auction for those:

Sorry, I only need: FC0.01840 – Gear Lever Plate Chrome (picture #14). I already have the shift lever assembly.  Thanks anyway.</span>

They only had the brake hub in stock and only in magnesium.

[John Kwong]

I am on Ebay all the time.  I have seen complete rotors occasionally but never the gear lever mount.  I have a 40mm brake hub now but need the 50mm.  Just seeing if anything comes of this.  Thanks for your input.

We only have a few days left(Oct. 31) to go for this free money.  Any funds generated are much needed.   Here is a pic of our freshly completed track.

Facebook link should work now.  Thanks for the support.  All we are asking for is a simple vote, nothing else.
