just leave him alone guys the motor will be fine at 4700. that sounds like a sweet cam bro :thumbsup:

U should do rod and flywheel

Im getting ready to use a 388a on my blue clone in a couple weeks it was an extra that came with my f200 ill make post if i remember!!!!!!

cant use the cam because the rpm limit but 1.3 stamped rockes and guide plate will help u can bypass tje govenor like i did look at my thread about is it safe to bypass govenor i put directions on how i did it and itl worked real well, its fast!!!!!!!!!!!

but is 1/2 good enough? :confused:

i have an all stock predator on a many bike still have govenor i put a 1/2 inch echaust on it will it hurt the engine i just want sound not performance!!!!!!

mini makes 15 with stock carb and small cam

Any one im making it out of pipe

i have a stock briggs with no govenor i rev pretty high do these motors run better with a long pipe or short i have a screw on muffler at the end

can anyone answer my last question?

good idea get some good mods air filter header spring e tube jet

new 14 pound valve springs wounld be good and a cam would make it really fast or some stamped rockers

o yeah i have a yf200 r1 that makes 19-22hp and it is so fast

it should haul butt my 8hp clone hauls butt

also get heavy duty valve springs off of nr-racing.com go to performance parts on chinese 13hp and it will take u to were u need to be

if u want to mod the engine a little and really make it wake up get a gx390 air filter adapter and exhaust u will need to rejet the carb

not unless you remove the govenor and twist a little more rpm not too much though i wouldnt twist more than 5500

did anyone buy the azusa mini bike kit from OldMiniBikes.com? is it good bad? was thinking about buying it

that duromax 16hp engine looks about the best your going to get as far as price! get the onw with electric start its much butter! :thumbsup:

thanks thats an awesome idea ill just get 16 pound springs :thumbsup: what are better the 1.3 or 1.2 for my set up?
