the mod has performed reasonably well. it idles well. has great low rpm torque which i enjoy. I am a cruiser not a racer so good low speed response is more important than high end horsepower. the motor wraps out just fine pulling hard through the power band to within 1k of redline. i dont beat on the old girl any harder than that. I am still tweaking the idle mix a little. i also suspect a cracked coil due to intermittent bumbling. I have ordered a Neon coil i will attempt to adapt. more mods. fun fun.
i do notice condensation on the outside of the carb and my metal plate flange. this concerns me and is the reason for considering heat. in looking at the two rubber hoses in the coolant system there is hardly room on the lower to fit a t with a barb. i am going to attempt the mod next week anyway if i dont hear a better idea. I hope to do that at the same time as the coil.
i have noticed that the auto choke does not seem to be opening all the way. i am thinking of converting it to a manual one by attaching the choke cable to it to force it open and closed. i have power and ground to the carb but it takes a half hour of riding before it opens up and even then is not in the full open position. this is causing bad gas mileage.
i did order 3of the 5 way pieces for further mods in case this one didnt work out. was there a reason you didn't just run flex straight from he 5way to the intakes? I am also curious as to why 1 inch would work better. my flange is a 1inch hole. It mated up better, so the throat i am using is 1inch size but the runners are all 1 1/4.
The hose is on its own air filter separated from the fuel intake system. another thought I had was that the choke not opening is causing excess cooling due to continual vacuum above the throttle butterfly. I am going to do a little research on the dune buggy site as suggested and see what I can find.Where is your crankcase breather hose attached? Could that be the cause of the condensation? When I blew a fuse I lost my electric choke resulting in a rich fuel mixture and lots of water vapor coming from the breather hose.
