Re: 30 psi compression on hot pink G1
This is a 2-stroke engine correct ? oil in gas mixed right ? piston looks like one that has been run without oil mix. I do think this is the 215cc two stroke oil injected engine and no way would I trust oil injection on something this old.
I may be wrong but always good to ask. Here is a link that Slo posted several years ago that might help you learn more about this classic. https://www.buggiesgonewild.com/showthread.php?t=76176 |

Re: 30 psi compression on hot pink G1

Re: 30 psi compression on hot pink G1
Leon seriously just stop. Nobody thinks you’re funny and I’m not sure what you’re trying to accomplish.
I can’t think of a better way to ruin a rod or the needle bearings on the bottom Of the rod seriously stop giving “advice”. I’ve said it before, take that advice to Facebook. Not here. We do things differently here to avoid it turning into Facebook arguments and competitions and etc. I will just say this so if someone searches this later they have something to reference. Its better to Use a bolt, nut, and a deep socket big enough to fit the wrist pin inside it and tighten the nut/bolt to press out stuck wrist pins. But alyle already has it removed from the engine. He’s got pictures of the piston in his hand Remind me never to buy anything Leon Willis touched. You’ll have a jacked up rod, melted piston, and a clutch full of oil |

Re: 30 psi compression on hot pink G1
For as scored as that piston is, I don't know how the cylinder can't be as well. Personally, I would just go ahead and do the entire top end. The one time spend and work should last you 20 years or so.
Regarding the needle bearing, I have never found the need to replace them when doing a top end, not that I have done a ton of them. |

Re: 30 psi compression on hot pink G1
Yeah, I have restored a lot of vintage carts now and have found that, invariably, people either don't know what's wrong with their cart or flat out lie about what is wrong. "It just needs it's carb cleaned." Well, why didn't you clean it so that you can sell a good running cart rather than a non-running one? Now that I know what I am doing a little bit it's a lot easier for me to see through the BS.
Regarding your top end, there are a lot of kits out there that contain all of the rings and gaskets and stuff. I would bet that virtually all of them are made in China at this point so there may not be a big difference from one to another. Getting something from a site sponsor is preferable, of course. I have never had to buy anything from him, yet, but everyone here swears by Plowman's for their G1 needs. |
