ok thanks cam. I'll fix that up and i was looking at getting a big bore kit. is there anything overly hard to changing a piston and cycl to a 49cc kit?.
Theres nothing too overly hard but just know that in order to get any performance theyll need to be refined/blueprinted.......Any kit you buy will need to be except Sams kits because he refines them..............
The engines were designed for long term use lawn equipment tool engines...None of the internals flow together smoothly to gain velocity to make true actual performance,, power and revs until theyre modded to deliver the goods.........In 2 stroke;-high velocity and high compression makes power...In 4 strokes its high compression,,tight camlobe overlap and high flow volume........
Just know if you just buy a BBK from someone except Sam that when you assemble that engine its not gonna give the true performance it should and wont last very long...........Either buy one of same kits and raceport the lowerend for high velocity flow or do some research here and bust out the dremel and have fun...............Good Luck
The flow has to be smooth to get velocity.....It takes time but the power is incredible in all 3 powerbands............LOL
The corners of the cylinder are the biggest restriction of true velocity...Not on my cylinders....Between the lowerend and the lower enginecase the flow is smooth sailing all the way to the top........LOL
Heres what a stock lowercase looks like with just a FCC installed and the way most keep their engine lowerends..mp in the middle hinders flow
Heres what a raceported lowerend with FCC looks like...The speedbump in the middle is turned into a ramp to aid uninterrupted velocity and the case in the center is dremeled out so the 3rd port on thid build-up isnt being hindered to flow fuel into it..The difference in performance is like night and day......
