If all you did was replace the clutch pads, why would you think you need to adjust the timing?I need help i changed the clutch pads on my bike motor now the bike will not start i have spark i was wondering if there is a way to set timing. 49cc
It sounds like i am your next door neighbor, because i just bought a pk80 and it is a pooch.Its realy my friends engine he lives next door, he was so disapointed with his PK 80 that he dont care if it blows, bu now he glad hes got a bike that runs anyway. He says SkyHawks are the best. I had a PK 80 ran strong, cops had it towed, anyway I'll tell him about if he goes to far with the timingl I hope we can tell by the plug chop. He blue one engine, plug looked lean and he ran it wot for about - miles, antway we got a Ace hardware, thanks for keeping me informed, Thanks Alvin
Hey Biknut, can you verify this, please?Turn the magnet counter clockwise to advance the timing. Don't go more than one keyway width. Try half a key way width first.
It is very confusing, but that's correct. Looking at the rotor, the motor turns clockwise. Adjusting the rotor counter clockwise advances the timing. It's counter intuitive.Hey Biknut, can you verify this, please?
It seems that the crank turns clockwise? and if you turn the magnet counter clockwise wouldn't that retard the timing? Just asking?
(Some of Jim's pictures at the beginning of this topic it looks like the magnet was turned clockwise?)
With that being said....
I took my key out and moved the magnet counterclockwise on the crank, about the width of the key-way, and it did make a noticeable difference!! I just don't know if I advanced or retarded it.
LOLHey Bikenut and gokart25 --
I don't get it. If your rotor magnet is spinning clockwise it seems obvious that turning it several degrees in a clockwise direction would be ADVANCING the timing of the spark (as shown by Jim's pictures on page 1 of this thread). How can moving the rotor magnet counterclockwise be doing anything but RETARDING the spark timing? I hope someone out there can clearly explain that mystery to me.
In the meantime I am going to experiment with the magnet position by first removing the keyfrom the keyway, then turning the magnet slightly clockwise from its original position, then tightening it down firmly using a star nut (hopefully it won't slip) and see if it is better. After that I will move it slightly counterclockwise from its original position and check the result. I will then report my findings on this thread.
