engine swap

I'm a beginner to minibikes and generally have limited mechanical knowledge of engines (but youtube and google are a great resource as well as this site and i learn more every day). I was thinking in the future to do an engine swap on my Coleman B200R (or even an RT100, although its probably not...

Hello! My grandparents gifted me and my siblings 2 Manco Thunderbirds, when we were smaller. While visiting them, we always had problems with the engine (TECUMSEH). After one year of no usage, we always had to bring them to the next workshop. Today, we are 19/20 years old and though about...

Hi, new comer to the mini bikes world here. I just was fortunate enough to pick up a Super Bronc 2 VT-1040 lately. Played with it a bit and not sure I'll keep the tecumseh (HM100) around for long. Ideally I'd go for a used honda engine, if I can find one, but I heard there are some good...

Replace engine.

Happy to have stumbled across the OldMiniBikes Forum, on a hunch I purchased my 1st DB on Craigslist and am blown away by all the things/ways I can go with my DB. It was a great find, everything seems to be in great working order. As you can see in the pictures, and from what I've read numerous...

Just need to know what parts I will need to make the switch. I will be installing it on a Murray Track 2 Minibike, which currently has the stock 3.5hp Tecumseh power sport engine and stock twist throttle. If there are any helpful links out there that will also explain how to go about doing...

I have the stock engine with the governor being disabled and it gives good power, just looking for a little bit more. What engine would you recommend for a swap? Do not want a predator, maybe something smaller and what other prices besides the engine will I need?

I am going to swap my DB30 engine with a predator 212cc engine. How can I mount the motor without the plate?:shrug:

Has anyone ever used/thought of using a router for woodworking as a milling machine? I’m doing a engine swap on my Doodlebug and I’m planning on drilling out the slots instead of using an adapter plate. Then using a wood-router with a milling bit to clean out the slots. Has anyone ever done...

Hi, I think that at christmas this year I am going to get a new engine for my db30 and I have a few questions. First off what is the shaft size on the stock db30 clutch? I have heard that it is a 5/8" clutch but I saw on one website that it was 3/4" but I thought that was generally larger...

Hello all, I am looking for a couple things for a DB30 that I just picked up... I need to know where I can get a torque converter for it (and what model for the 97cc engine) I also would like to know where a good place to get a 6.5hp clone motor Thanks for the help!
