Mini Bike & Go-Kart Parts

Ok i just got a chance to talk to the man in the know bout the Card Troll Pumps in Kimball, NE. Bout a mile North of I-80 on Hwy 71. It's on the Westside of Hwy 71 @ the Stop Light (only one in town) they have minimum 91, sometimes it may go as high as 93/94. Just depends on whats available out of North Platte. Was told it'll always be 91 min or better. It's also filled regularly, for it's only a 1000 gallon tank.

The East of the Stoplight has 85 octane ethanol free...

had little down time to work on epoxy the intake runner. i am using a product made by goodson made just for this.

the bottom floor is terrible on these 5hp's. not to mentioned the weird outer intake design has it enters the intake and bounces up and over and around the valve stem and crashes on the flat back side wall and up.

filling in the floor and back side and making it ramp up and out. also going to change the intake port to more of a round design to match up with my new intake manifold/carb i will be using.

stuff is easy to work with. i will be able to go back scuff up the epoxy surface and leave more of a textured surface if need too.

Can't wait to see the finished port, and the hp results!

that would be a full 5.5 hp .....lol
i don't think the power gain will be crazy. it should just run real good for a stock/cam engine with some mods done to it and pull up to 4700+5000 max rpm's.
going to be a slow build with my other stuff coming up. i just finish up two race engines. 225cc and the other one i can't talk about....lol
also the bike i want this flathead to go on will need the rims re-chrome and they go out in two weeks to get plated and when they come back?
that will slow the project way down and my racing. but i will keep posting when i can .... thumb1.PNG
