engine

btw i do however have on a very nice reflective vest! keep the negative comments - only positive input needed - thank you - I built this and feel very accomplished dont try and take that away!

I have an upgraded 212cc engine that didn't pan out with a motorbike project. I have no idea what to do with it. Anyone have any ideas what I should do with this thing? Its one **** of a paper weight... (Mod 2 cam, 18lbs springs, cnc connecting rod, cnc fly wheel, governor removal, bored carb)...

So i have the Chinese 49cc and its killing me. every day i feel like the motor hates reving less and less. it started to like to run around 2900 rpm and now it dosent go past 2400 without vibrating everywhere. Like the title says, i wanna buy a new motor. I dont care about cc specifically...

haven't heard back from the guy i bought it from yet, wonder if anybody on here might know what specific brand this motor might be. it has 3 wires coming from the magneto, a curved clutch arm, short intake, and flat head case screws that would make it "unique" to who manufactured it. My other 2...

I've run almost 5 tanks of gas and it's well broken in and been running great. I was about 15 mles into a trip going around 30mph and the bike lost power (full throttle got me 20 mph). I tried to shut it off but nothing happened so i braked to a stop which cut the motor off. It then smoked (from...

So I'm replacing the 66cc chinagirl on my bike with a 79cc predator because I got tired of the chinagirl breaking down every 3 weeks. Some people said they want to follow this build so I'm making a new thread in the proper location on it. Here's the pics so far, as you can see, the engine barely...

So yea, my 66cc chinagirl engine breaks like clockwork every 3 weeks or so, never the same thing twice, but always something new to fix, and I'm sick of it. Plus it's really underpowered and has no hill climbing power and (at least in my opinion) pretty mediocre speed. So, I want to swap it out...

Hi everyone, I've been having some strange engine issues and would appreciate any insight from some more experienced engine people. For the last 2-3 months, my bike has gradually gotten slower - lost pickup on the low end and lower top speed on the high end. I haven't changed any major...

I saw this post where a guy just briefly mentioned about how a guy made panels to go on the side of his bike frame to cover the engine and everything to make it look neater... I am not going to quote it or give you a link because he just said what it typed above. But, how do I do this? I haven't...

Where and what kit/engine should I buy for the fairest price? I already have a cheap ebay kit that costed me 130 dollars, and it was labeled as being 80cc... which i know really means 66cc. Is it actually 66cc though or is it 48/49cc???? I need to know. Anyways, I am having trouble getting my...

hello I am a new motor bicycler and I am very interested in buying/selling/trading these parts and accessories. currently looking for some gas engine kits email me with any detailsdance1dance1

So my spark plug fires just fine when I hold it against something, but when I try to get it to fire in the cylinder it wont fire no matter what I do to it. Any ideas? The engine is a grubee skyhawk raw racer 66cc and I assembled it last night and now can't get it to start cause of this.

Forgive laziness and grammar I did this once already and the site deleted. So my patience is limited now. So to begin my problem. The bike has 640 miles on this 7g kit. I was riding today and went through some roughish terrain. After that the bike idled down sharply. It didn't shut off but...

is it safe to ride my bike after only 1 hour of waiting for permatex super copper to dry?

My kit is new, and the engine's never been run. I wasn't getting spark, so I replaced the stock spark plug with a Champion one. I still didn't see a spark, but this time, I just touched the end of the plug while cranking, and it gave me some good consistent shocks. The only thing is that I...

So I've read a few threads on here about how terrible gasbike seems to be. But I've also heard from several people that they're decent kits. I'm curious. They're having a "sale" right now (which I know isn't a deal really) for a 66cc kit for $188 (after calif. taxes). I'm interested, as I'm not...

Hi, let me start by saying that I am not too savvy with mechanical parts. That said, I've tried my best to make my HT engine work but even so I really need your guy's help. Engine Mount Firstly, the engine has never fit onto my bike (front tube is WAY too fat). I removed the front mount...

Hello all - I saw one of these bicycle engine kits online and knew that I had to put one together. I had a couple of bikes in the garage, but this 1991 Miyata 914 SE was the only one that could accomodate the engine in the frame. I ordered a cheap kit from eBay knowing that it would be ripe...
