So I've been working with my longtime friend and ex Superkart racing champ Dave Martin for over years- Dave's a JPL engineer who was responsible for rebuilding all the Space Fuel pumps in between launches with '"0" failures throughout his entire 30+ career- pretty impressive, right ?? this particular kart is an RD400 powered laydown- the original ignition system finally failed- (a total loss battery trigger system), so his only other option was converting to either another total loss system, OR finding a TZ250 ignition which we originally thought would be next to IMPOSSIBLE to find, so after over WEEKS of searching, we located a used but operational stator assembly from Germany and a matching ignition box from England- I never thought in my WILDEST DREAMS that I/we would EVER find these parts !! so NOW that's missing is the ignition rotor which we located in Miami Florida- u NEVER give up - so now it's just the task of connecting and routing all the wires and it OFF to BUTTONWILLOW for a day at the kart track!! YIPPEE!

So my buddy Scott Holden says his '82 Honda XL500 has a head gasket leak, he then sends me a pic of the "reed valve"?? I told he should probably get off the SAUCE, they're CAN'T be 4 stroke out there that was EVER MANUFACTURED with a frigging REED VALVE, but man was I WRONG!! there it IS in plain view- A 4 STROKE with a REED VALVE- I'm wondering what type of air flow engineering that's behind this design?? ANYBODY out there KNOW ??.

Still chasing our tails throughout Fridays practice at Willow Springs trying to figure out the engine issues on Shawn's TZ250 - the new CHASSIS setup was easy, no worries there, but getting it to run correctly was another issue completely - we tried NUMEROUS jetting changes- the bike just REFUSED to run above 12,000 rpm's, but anyone who knows me knows that I NEVER give up, so we leaned towards something mechanical, and found out that the upper cylinder Power valve bracket had loosened allowing the opening cable to pop off, which kept P/V closed - so after adjusting the cables on both cylinders properly, the bike came alive - Shawn P3, Dylan P5 In open 2-stroke - Thanks for hanging in Shawn-
