Hello from the phillipines

hi there im niky from the philippines i recently bought an ht china engine 49cc, almost done with the build, fabricated reinforced cruiser low rider style bike with springer fork, i havent got a closer shot at the engine i forgot to took some yesterday, uhm iwas just wondering can i port polish my exhaust/intake trim my piston in the intake area, and put some ramp on the piston crown, lapp the cylinder head to 0.5mm and change the head gasket to a thinner 1 and some simple mods before i break in my ht engine? any other suggestions would be super much appreciated, thanks in advance happy riding

here's an fb link on my bike:cant seem to upload it properly here

maybe later il post how poorly they built the engine im seeing lots of possible oil leaks with my ht, thats why if ever while i tore it down i might as well do some mods, any suggestions oh great ones. thanks in advance

me and my friend broke down the engine and found bits and pieces of metal inside my ht so we washed it re greased re oiled it because there aint much of grease/oil inside the bearings and pin bearing took of some burrs from the casting,the magneto had tons of metal grindings on it also then i put the head on my moms granite bar flashed a light under it and found that it wasnt really flat even with the ring, so i lapped it,so far thats what ive done just lapped and regreased cleaned the innards of the engine, also we found out that pin bearing is similar to a yamaha jog or honda tact i think, gonna go to the local scooter shop and check there bearings if they have the shelled ones so before i broke it in i wont have any piston play,and also we found that the black wire is the neg and white is positive hheheheh so id be able to puts some lights and horns if ever,

yeah i bought it brand new around 196.46 USD, even inside the engine got tons of bits and pieces of grinding i was like mining for silver inside the engine. XD what bearings? the large ones on both side of the crank? i also notice the black oil seal i think imma change that to,later im gonna go to the local scooter shop and see if they have some piston kit available for ht engines im pretty sure this ht engines have the same size of honda tact and yamaha jog, coz around my area there are tons of paperless 50cc scooters so they chop it up and sell em for parts, btw what oil should i spray inside the engine coz it sorta have some type of oil inside when we opened coz we washed all the engine with gasoline to remove the grease and blew it out with air compressor, we did have a hard time opening that engine we had you tube it, while we were breakinng the engine down we had a crowd of audience asking questions where do you put the gear oil?XD even my mechanic was wondering where does the gear oil go here? ehheheheh, also imma change to an ngk iridium plug if ever my friends motorcycle shop can get one, didnt like the iridium denso it only lasted me 6 months or so in my suzuki raider r 150, but the ngk iridium took almost 1 and half a year before it died, does any one use other cdi other than jaguar cdi on these ht engines, coz i see that the jaguar cdi had 4 pin and i was looking around sulit.com.ph the philippines ebay, and cant find a 4 pin cdi, any ways thank you so much almighty UVsaturated and oh great maniac57 for the tips, imma update later and took some pics if ever.

cleaning the engine again this time gonna sand those un even surfaces if ever i get to borrow my friends dremel XD

almost done with the build, i forgot about the rear sprocket alignment wobbled like **** said my mechanic, we had troubles at first starting it, but it was just the magneto, just a few more things to do before break in re elbowing the muffler coz i assume im gonna fry my leg with that muffler on that set up then just porting the intake and exhaust of the muffler so it will match up the ports, havent got a hold of my friend with a dremel and a carbide for it,
