The Honda engine for Jr1 is a GX200 which will be using a Tillotson carb with linkage, EC Birt manifold, Mikuni fuel pump, K&N style air filter, RLV stainless exhaust with muffler, 2-Disk adjustable clutch, engine mount, Each engine is disassembled, governor removed and then they are measured and matched for cylinder to piston height, head CC. The valves are adjusted, manifold matched to head, ignition clearance set. Then they are inspected and side cover, head and valve cover bolts sealed by the tech director. You will be able to adjust the carb and clutch only with no modifications allowed on either. We have decided to use the rope start instead of the onboard electric to keep the cost down. You may add a starter nut if you wish to use a hand held starter. The gear ratio will be set for each track to keep the rpm below 6000. The lap times are comparable to the Comer 80. The price to purchase the package is $850 and will be available from most kart shops in Colorado. You will also be able to rent an engine package by the race for $35 or you can sign a contract to lease purchase a new engine package and keep it on your kart for $75 per month for 12 months. This is the same engine which we use for kart rentals with a different carb, manifold, exhaust and clutch. The engines will not have a problem with the valve train when used below 6000 rpm. We have over ten years of experience with the Honda and it is the most reliable engine for this class. We run them hard for three or four years before we work on them.
Freeze, (the original Briggs aficionado)
If Briggs really knew what they were doing they would not have to make so many changes to their engines. How many versions of the flat head and Animal are out there? They still have not figured out that the screws that hold the exhaust to the head are too small along with all of the other weaknesses like no two engines are built the same. What has Briggs ever done for Colorado racing in way of support or anything for that matter?
