thanks and the pic of your DB30 is bad ass
it looks way cooler than it is. it's got a wicked mid-range vibration right now. it's either the crank (putting my money on that, have a good GX160 one to try in it) or flywheel (from ARC, doubt that's it) and i'll be swapping parts soon to figure it out. the carb also isn't tuned quite right which isn't helping either (i'm 99.8% sure that has nothing to do with it).
it still hauls ass but will knock your fillings out (which is why it's parked for now, that vibration isn't good for it).
it pulls on my friend's 110cc/4sp DB like crazy after 25mph. i have to fully let off the throttle to not run into the back of him. the low end on my 5.5 sucks.
it sucks spending a bunch building a motor and then having problems. everything is within spec on it too. the only stock clone parts left are the case, crank and head. i'll figure it out but at least i get to learn from it.
i almost have more fun trying to build stuff than i do actually riding it. :laugh:
