I am a newly registered member of the forum. I have haunted this site for years prior though. Slipping in and out like a ghost when I need a quick answer or some advice to get me out of a hole or to shine enough light on my 2stroke path to help me find my next step. And, then i'd slip away. Without a thank you or respectful acknowledgement that the information you supplied was definitely spot on and sure saved my ass and probably money...sweat...and tears.
I have had the fantastic opportunity to build my tenth two stroke. It has been most enjoyable torture I can imagine. I have developed skills and wisdom regarding 2stroke motorized bicycle engines that are now precious gifts to me. I paid my dues in that hot ass garage bent over that temperamental 2stroke cussing and throwing tools. Trial and error were my shop buddies.
Somewhere along the road I encountered this site and it was a blessing from the gods. I want to give genuine thank you to all the members new and old who have contributed positive, factual, and clever information to this site. It would have been impossible to reach the level of confidence I have today in troubleshooting and repairing my engines without your help. I'd buy you all a beer, but...I'm a little short. But, please, accept my thanks.
I had some difficulty with the initial start up on this latest engine kit. I don't think it's actually the YD 100.. officially. It looks exactly like it however. When I mounted it and went through all the parts and connections, I noticed that the gap between the magnet and the coil arms was kind of large. I've used a matchbook cover to space that gap before. No problems. This time the gap stayed that way even with the spacer.
I didn't spend too much time worrying over this and figured that, you know, this being a very fine quality piece of Chinese manufacturing, I should have nothing to worry about...well, after a struggle I got the motor to fire up and set out on our maiden voyage. 1 mile out..back fire...backfire...explosion...oh my god..
The engine was GLOWING hot. It turned the banana pipe exhaust blue! Great, I thought, that motor is trash. But, I don't give up easily. I researched the forum and went through my steps to see where I failed. Evidently, I got the fuel mix wrong and this created the condition that led to the overheating. Thankfully, there was no damage and I'm back to where I should be.
I bring this up because while I was reading threads in the forum, I saw some advice a member gave to a person asking about overheating a new engine and possible consequences. This member said that overheating can lead to the magnet expanding under the intense heat and contacting the coil causing backfiring and, additionally, there is the possibility of (and this is the beautiful part) the magnet becoming de-magnetized.
Okay. I made a note of that and was sitting in front of the bike later on trying to figure out why the new engine was acting so weak and erratic. The screwdriver I was holding happened to slide past the magnet and I realized it didn't stick to it. I'll be hornswoggled!? The magnet was so weak it would barely stick to the fridge. I couldn't believe it. The overheating had caused the magnet, ultimately, to lose its most important quality. I would not have known this or even understood the possibility could exist if I had not seen that information on the forum.
I swapped out the magnet with a spare magnet with lots of "stick" and now it fires up instantly and has good strong rythmic power. I cannot say thank you enough. I am so grateful for that thread. I can't find it and don't know it's author, but it's not him alone I seek to express my thanks. Everyone contributes to the success of everybody else when you give solid, road-proven information relative to the subject under discussion. And, that is what I am grateful for the most.
