Change it from the very start BEFORE riding as many have crappy shipping oil . Also change the gear lube . Most use 10w40 in the engine and 80w90 aka GL5 in the gears . Simply let the engine warm up and get a oil catch pan at any autoparts store to catch the old oil . Some have two drain plugs . Most use 750mls or almost 3/4 a quart . To check the level one filled and started up then shut down , remove the dipstick , wipe it and insert it WITHOUT screwing it in . Now my Echarm the dipstick needs to be screwed in . The oil catch pan is great way to not make a mess as it has a wide open mouth on a side with a spout to pour it out . Any oil change place has to take your used oil as they resell it to refineries .
New and after initial oil change change at 250 or so miles . Will have ring dust in it and on the second time too . Amounts will vary on break in method . I change mine at every 1,000 miles but you can go by the color as its golden when new and will blackened when it needs to be changed . All black it is past due for changing . Make sure to clean the oil screen everytime since these scooters do not have a oil filter like a car does

Yes I had a 50mm cylinder and used the stock 40mm head . Compression is high with that setup

The valves being too tight baffle most shadetree mechanics minds as it gets fire , fuel and compression but no start . This is one resson you find em used for 100 bucks . Mine got loose and it would stall just before coming to a stop but start right up . An adjustment and it was new again . All 4Ts will need this at least once . Some need adjusting out of the crate according to my scooter dealer

Wider tires will not make you any faster . Taller tires can in some cases . Most can only use one size where some may go up 10mm wider providing you have enough clearance . I like to have matching tire sizes myself as my 2T uses 130/60/13s which I call "doughnuts " This place has it the easiest to look for tires by size and has many good brands www.motorcycletire.com/merchant2/merchant.mvc? Here is a visual calculator so you can compare two diff sizes www.tacomaworld.com/forum/tirecalc.php I would look into Shinko or Kenda is on a budget but its well worth the extra to get Pirelli , Michelin , Dunlop or Avon brand . The cheap tires are hard and do not grip as good but last a while . Some performance tires like Avon Viperstrykes are softer and do not last as long as others so its best to stay in the middle . I will be going with Pirelli SL26s once my tires are worn out . I strongly suggest you get them balanced ether with a static bubble balancer or at a MC shop like CycleGear . CG charges 20 to mount and balance if you buy tires from them and 30 if you bring your own tires . Note they do not R&R the wheels from the scooter or motorcycle so you would have to take them off and take to them . Some scooter shops in town offer tire balancing . If no place does near you Harbor Freight has two models www.harborfreight.com/catalogsearch/result?q=balance mine was done with the stand model . To me it is dumb that they are not balanced and this is why they bounce and shake . Once mine were balanced it was smooth riding . Also it is a good idea to replace the valve stem with a  degree type as some are known to leak from the factory |

Take off the pipe and blow through it . Sometimes the baffle cone can break and turn into chunks I like Motul 710 as it is injector safe . Bel Ray is another great brand . Make sure it says itf for injector if your not premixing I get mine from www.cyclegear.com |

LOL there is full synthetic and synthetic blends at any store . I worked at Jiffy Lube and I think it was the ZR1 Corvette that partnered with Mercury outboard called for Mobil1 synthetic oil in the manual .
You can put in synthetic gear lube at any time and I use Mobil1 in my 2T as my Echarm calls for 15w40 in the gears instead of 80w90 GL5

Also check the float valves as it is easy to bend it while taking it apart

Many come with a 17.5mm or 19mm . A 2T powerkit with a 70cc BBK uses a 21mm carb so yes its too big . A Suzuki RM80 uses a 28mm and a scooter does not make anywhere as much power or RPMs as that can . With a 49cc engine , airbox and stock pipe it will never have enough flow to use a large carb like that . A lil bigger works compares to a stock but too big will hurt performance and tuneability

Try lighter rollers and a larger main jet

I have put over 300 miles in a day on my 2T when it was a 50 . My Echarm I can ride all day with no worries as long as I have enough gas . Make sure everything is tight and have plenty of tools under the seat just in case you need em
