4 stroke motorized bike 

2 strokes are okay, had one and had to carry a couple of tools becos the vibration would loosen nuts & bolts . . . now i got a 4 stroke - gotta love that that pull start 🚴‍♀

Thanks! Im really happy with it 8 months later.

Wow thanks, sounds like a good combo. I think it is just fun to build them, not expensive and you can do whatever you want 👍

Thanks!

I agree, I tried it but the cap is in the center and gets in the way.

@@goose278 its worth capping and welding on the side

Thanks

Thanks, it did really change the look. I hope we can see your project on here somewhere soon

Wow that's great! So far so good I haven't had any more chain problems at all. I put a disc on the back and I got a new hub for the front but haven't respoked it yet

Thanks! Yeah I kinda dropped off the face of the Earth here with this thing but there is good news , 🙂it runs great and I should put something else up soon!

Probably was, it did a lot of popping and snapping noises😬 no issues now.

Thanks Magpie!

@@goose278 it's my aim to have a four stroke engine. I've had the wee 49cc two stroke chinese thing for 12 years now, it still runs okay on the flats😊😉 it's lost it's power for the hilly bits😆😂😂 I tried a longer pipe which increased the power, yet the tick over had to be stupidly high to prevent it from stalling when stopped in traffic😆😅😂 plus, the clangity clang of the two stroke gets a bit much after 20 minutes🤔🥴😜 great inspiration, thank you...

Yes, I like the belt transmission for these, beware of the chain type I would say .

Thanks, I need to put out a new video.

Thanks Joe

I can't right now but I will try to gather that up to you later

OBRIGADO MEU AMIGO, PENA QUE FICA MUITO CARO IMPORTAR ESSA BIKE AQUI PARA O MEU PAÍS. AQUI A CORRUPÇÃO NÃO PERMITE QUE PESSOAS COMO EU POSSA IMPORTAR ALGO TÃO MARAVILHOSO. MAS DESDE JÁ AGRADEÇO SUA PRESTEZA. THANK YOU MY FRIEND, I'M SORRY IT'S VERY EXPENSIVE TO IMPORT THIS BIKE HERE TO MY COUNTRY. HERE CORRUPTION DOES NOT ALLOW PEOPLE LIKE ME TO IMPORT SOMETHING SO WONDERFUL. BUT THANK YOU IN NOW FOR YOUR PROMPTNESS.

I'd really like to hear how it goes! Should be quite a challenge.

Thanks John it was fun! Haven't ridden it in several months though

Update.. you inspired me to bring it out. It has been sitting for months, it started in 2 pulls. I drained the carburetor out before putting it away.

Yea these kits don’t come with a cooling system I have baught and assembled multiple engines this exact make and model they DO NOT come with a fan or anything like that it’s an air cooled 4 stroke

@@thakoalaking5022 They most definitely do :) there are fins under the cover that hosts the rope-pull start, and the cover is molded to direct the air where it needs to go. Unlike the 2 stroke kits that only get air-cooled when in motion, the 4 stroke kits are being cooled even during idle

@@vladmokrenko7834 check my videos bud i build motorized bikes for fun the last one I had was a 4 stroke shwinn whizzer that was stolen from me the motor I purchased and built did NOT come with any cooling system whatsoever ever also on 4 motorized bicycle enthusiast pages and never seen them on a 4 stroke or 2 stroke it’s a nifty idea but not one I could see catching on with a motor that won’t warp enough from heat to cause ANY significant change unless your running a shit transmission but that’s on YOU

@@vladmokrenko7834 btw I have this EXACT kit so no

If the bike is in motion, some cooling should take place, as it does with the uncooled 2 stroke engines, however on my 4 stroke engine I prefer the well engineered intact cooling system. The factory design cools the engine at all times, whether moving through the air, or not.

It is a very well designed engine

Thanks Jorge

This was a few years ago, but yes it came with the crank and sprocket. I was very impressed with what I got for the money.

Also it was a bit wider but I thought I would notice it but I really didn't.

Hey Chris! That is a rag joint it's not a very good sprocket assembly but it comes with the kit. In another video I have it shows the better route to go, it clamps around the Hub and it's not as wacky as that. that is very hard to get set perfectly. The Hub mount is not that expensive and it's definitely the way to go

Hi Dale, that was just some scrap I had laying around. And I just don't have time to do any projects . sorry

A MoPed is a bike with peddals and a motor, thus Mo Ped...how it starts has no bearing in the matter. I once had a TOMOS MoPed that started by peddaling backwards...

www.ebay.com/str/whatwears3 This should put you in a right direction🙂

So true, that would make a big difference.

@@goose278 I had a moped and I had to peddle it it was so hard

Almost easier to get off and push sometimes

I used the rubber handle off of an old umbrella on the factory kickstand. Clamped it with the old coaster brake bracket. Much more stable. It doesn't even try to fall over and it doesn't look bad.

Thanks Roger! It doesn't get used much but is still running good,I drain the carburetor when I park it.

It's been Flawless other than coming loose once or twice so you need to check those once in awhile. But it works great haven't had any issues. I think it's a lot smoother than the chain drive transmission

I have had no chain issues since that but the engine and sprocket were out of alignment a bit and the new hub mount for the rear sprocket fixed the tight and loose issue. I still have the stock front sprocket. The motor is still running great.

@@goose278 It's great motor, starts easily, throttles smoothly. I'm about to test a 41 tooth sprocket.

Just a cheap eBay motorcycle universal headlight with led's in it.

@@goose278 thanks! And Merry Christmas!

Thanks Leroy, at 8:00 on the video it shows what I did. It worked out really good.

Hey Dale, yes that kit came with a wide crankset but it's not too wide, hardly noticeable .

@@goose278 Thanks. Did you have to buy a 3 piece conversion kit? If so, can you tell me where you git it?

The kit came with a pedal set. They are a bit wider but not much

Lol yeah right

Yes I agree, it's mostly just a hobby not really a form of transportation for me, I just like to build something cheap once in awhile and have a little fun with it. Those electric bikes are addicting and quiet , really nice.

Speedometer is off and I couldn't get the tach to work with the 4 stroke. So... maybe you can make them work 😏

Yes, but it has a little drag if the motor is not running because you're pulling another chain. I guess if the motor broke down you could pull the master link off of the chain and pedal your way home

@@goose278 thanks

Yes in the video I showed it . I think its like 3 sections, made from the handlebar steel.

For sure, just idles nice and quiet..

I bought it off of E bay as a kit. In the description it should say if its chain or belt drive. I don't know about a conversion kit though.

Im using an rc type lithium 12v rechargeable pack . Lasts long with led's.

I bought the bike used for $50. But it goes for around a hundred at Walmart. Then the motor kit was about $185 all in all not too bad

Oh quesadilla!

Yeah,, I painted it black and it looks better. But Im keeping it as a cooling fan for now. It does look cool with a new flywheel and exposed magneto though.

@@goose278 so it blows air over the fins to keep the engine at a stable temp?

Yeah like a lawnmower

The original sprocket was about 26 or 27 miles an hour. But when I changed it to the 46 I think it is 43 I can't remember. It does about 35 miles an hour. But it doesn't climb hills as good.

Just checked on E Bay . it was a 32 tooth sprocket

@@goose278 thanks man!
