Thanks alot guys I really appreciate it. On another note I have caught the pocket bike addiction and picked up another 2 stroke stock Chinese bike that runs well and want to upgrade myself to learn. Is this Amazon big bore kit a good starter to learn on? I don't want to spend alot yet until I get some skill but for $69 bucks it seems not too risky and I might get a little more power. It says 3 groove cylinder? Are those boost ports? Thanks again for any advice
I beleive theres no rehabilitation center for such an addiction....It must be slowly weened from your system and if the addiction is strong it may take pretty long..
Aslong as you remember these are tool based engines and follow the rules in hopping up a tool based engine youll be a lot better off..Tool engines are built in a retarded fashion to promote longevity.Back when I was racing karts as a kid my dad didn't have $$ to throw at expensive racing engines at first seeings I have 4 other siblings for him to support aswell..He had a machine shop though and we used to convert McCulloch chainsaw engines into 75-85mph capable powerhouses a lot cheaper...In fact for the price of 1 racing engine I had 1 to race with plus 5 backup McCulloch's at the ready and I won quite a few races with them too.....LOL
No matter which 2pc head kit you pick whether 2 port 3 port 4 port or 5 port the kit isn't ready to rock n roll .Refinements must be made and another thing to note is if you don't lap the cylinder and headcap chances are youll lose compression in under 10 hours of running time..The hardened copper sealing ring would be a lot better if it was a lot softer too..
Just simply removing the basegasket to decrease squish and raise compression on what you have now will net you almost an extra 1/2 hp and some extra torque to boot too......
Just know with a dremel and a lil time you can easily add the extra power to what you already have and throw the cash at the more important stuff like pumper carb with V-stack n hp airfilter ,reeds , exhaust , gearing and some added bling...
Beleive when I say a cheap lil pocket bike can turn into a pretty expensive ordeal in a fast way and that theres tricks of the trade that saves money and maximizes fun..
If youre doing it to fix up and flip bikes believe when I say youre gonna be in for quite an experience especially when youre trying to explain to somebody all the stuff you did to the bike and them looking at you like youre talking a foreign language...Ive been through some pretty intense encounters and even had to throw quite a few off my property so now I meet buyers at the Home Depot up the block because its easier to chuck the bike in the truck and drive off when they go into lowballer mode........LOL
Have a ton of fun RPB.....I know I did....LOL
