i built a 196cc with ss valves
14cc head 10.8-1CR
32 degree flywheel timing
jets are 038 main 020 pilot
runs on 94 octane
gov is removed and block vented to valve cover, then to catchcan
motor idles fine and runs half throttle but full throttle it will bog down it seems and die
im assuming this is due to too large of a main jet? but from what ive read 038 main is what is common to be used with open header and air filter kits
so i was thinking maybe its starving for fuel and i need a fuel pump?
maybe i have a compression leak somehow or its magneto gap related no clue
i tried cleaning the jets, and messing with air ratio screw
i cant recall if i tried running it with choke or not
im going to order smaller jets to try
but before i did i thought id make a post n see what others think
i wasent running a pcv valve between valve cover and catchcan and just installed one but havent started the bike yet not sure if it will change anything, and i have a fuel pump that just came in mail to try if its starving for fuel, i also have a brand new coil ill throw on and see what happens incase its the coil
another thought i have as im writing this is i wonder if its valvefloat? would that cause it to seem like its bogging and cause motor to die, rpm gauge says max recorded rpm was 3090 but im not sure how accurate it is it dosent seem that accurate while idleing
i dont recall it being high rpm when it seemed to bog and die though
what are your thoughts what should i try and thanks for any info
edit, so another thing i realized is the tank is barly a quarter full, but should be enough in there to keep fuel in the lines but maybe not while riding, if thats the issue im gonna feel stupid, gonna try with half a tank full see if thats the issue, still would be great to hear any of your guys ideas though thanks
