Well I actually meant late this week,,estimated delivery time is weds-friday..I had a hard time getting the jug off,,had to loosen the foot board and lift it up a few inches or it wouldn't clear..getting the circlip in the piston to hold the wrist pin in is going to be the hardest part,,my eyes are not getting any better,,it was either take the motor out or take some body panels off,,I figured the body panels would be easier..but if I took the motor out the circlip would be cake too slip in...well get R done...
Hey Geh,,
What you think,,maybe try a 120-125 main first,,remember its a 24mm carb?

Well Im in the process of doing the 60MM TAIWAN BBK with A10 cam,big port 61mm head and so on..figured I would start to post some pics of the process and document my results when finished... The scooter is a 2012 Taotao ATM 150,,the first two pics are crappy flip phone quality but I will have better ones along with a video in the next few weeks as long as I don't blow anything up in the process..lol..well if I blow something up I will post that too The kit wont be here until late next week sometime... Stay tuned... Tom   |

Yeah,,
I have no scientific evidence about my theory and theory it only is,,but I would think you are correct about anything metal on the engine acting like a heat sink...

The fuel has a longer way to go to get to the intake valve,,its going downhill so wonder if it acts like a ram air,,kinda good in a way cause the mix stays cooler,,and cooler means more power.I would like to see a pic of it mounted in the scoot.

I set mine both at .004 and checked them after 2000km,,the exhaust was at .003,intake was still the same,,pretty impressed,,I really don't go over 6K RPM's to often either,,no need with 16/37's in the rear.

I've ordered from Bike Bandit before,,they are good,,but you can find anything you need for same price if not better on ebay search...I just dont understand how ebay sellers can be so competitive with all the charges on there  |

Well the tit is rounded off on the forward spinning side,,its squared off/FLAT on the back side,,so when the motor is running forward the rounded side of the tit slips past/OVER the square extruding piece on cam,,when going backwards it will lock right into place,,just like a ratchet...or fishing reel like mentioned...Im seeing it now,,thanks guys!!

Nice bro..anytime I go for a ride longer than 30 miles I try to keep my R's down around 5 or 6K thats it,,they cruise nice there,,especially with gears.
Rock on!!

Ohh..thanks Alley!,,there is only one spot that it hits,,that's why you can move the motor backwards some once in a while..I still don't like the idea behind it...I think the motor would be better off just spinning back wards than the valvetran getting slam hammered..I don't think its actually possible for a 4 stroke to run backwards..I've seen small 2 strokes run backwards,,they don't run as good as they do forwards but I've seen it on my model airplane.

It depends on how many channels there are in the cam for how often it will catch when spinning backwards,,if there is only one spot for it to catch then you can spin the motor backwards some depending on where the channel is according to the tit.But if there are many channels then it will sort of act like a ratchet and you wont be able to turn the motor as much before it catches...hmmm..well anyways thanks for the replies,,now I know what the heck its there for,,IMO another poor design of wasted engineering.
As for ACR or automatic compression release on these small motors,,Ive seen where they have a slight high spot on cam that hits the tappet where the exhaust valve will be held open a crack just at low RPM to help start the engine,,once the motor gets over 300 or so RPM's the valve will not even notice the high spot and run normal,,not sure exactly how it works (centrifugal force maybe cancels it out my guess) but the high spot must be in a different spot from the exhaust lobe..and if the valves are too loose the ACR wont even work..I have this on my 14hp Kawasaki FC-420V mower motor.The GY6 has so much compression that an ACR might not be practical.

more days or so till it will warm up..hope we have some nice days before that..
