Doodlebug minibike sprocket adapter install and top speed 

Nice!! I’ve been looking for a doodle bug for a while now. Gonna scoop one up as soon as I find one that the price is right. Great video brother

You save a lot of people an enormous amount of time with all your detailed mods and testing. Thanks for all the work you share

Great Mod using the split sprocket and adapter! I've always liked them for quick gearing adjustments. Certainly a 'must have' item for straight axle karts. I never thought about using them on a mini-bike. Great video as always sir!

I completely restored an old, blown-up and ragged-out Doodle Bug a few years back as a father/son project. It came out great. We also shoehorned in a 212cc Predator engine and went with the split sprocket set-up just like yours. I'm not sure I caught what engine you used, but I was surprised to see you didn't need an adapter plate. What size chain did you use? I can't tell from the video, but we decided to use the beefier, 420 chain size over the stock one, which I believe was size 35, so counting the teeth might not be an accurate comparison of our gear ratios as the distance between each tooth could be different. I can't remember the number of teeth we used, but the diameter of the sprocket was slightly smaller than the stock 35 one and would probably be comparable to your 66 tooth one. The front sprocket would have a bearing on this too of course. I'm not certain you didn't run out of road before the bike could reach top speed on the second run. I wouldn't mind the slight loss in 0-30 time with the smaller sprocket, but I would hope for a bit better than a 1 MPH gain in top speed for the sacrifice. The smaller sprocket does have other advantages that might tip the scale though, such as slightly better ground clearance for sharp bumps and spirited left-hand turns. Anyway, good luck, have fun, and thanks for the video!

Great job.I always enjoy watching your videos.I bought a new back rim for my mini dirt bike but I just need to order the sprocket.

That split sprocket is the only way to go .

just fixed my chain snapping issue on my doodle bug, after going through 10+ masterlinks i just removed the tensioner all together and moved the engine and bam no issues, minus hitting a ramp and getting road rash-

This is insane

Mine has a 5.4-1 ratio, the issue I'm running into is that I want too do what you did adding the split-sprocket, but my hub is a 5 hole instead of a 6 hole 🤔 can't find a 5 hole adapter or even a newer 6 hole rim.🙄 do you have any ideas or point me in a direction that might solve my dilemma?

I’m working on a Doodlebug right now!

Nice comparison!

Where can I get that exact adapter? I have that same back rim and tire. Please help

That was quick

What app are you using? I have a doodle bug that was given to me and I'm getting it spruced up. Friend I got it from said it would do 35mph plus, so I want too put it to the test! Great videos!

Can i use my old existing axle sprocket as an adapter and drill holes in it and bolt a split sprocket to it? Its on my yerf dog

is that a 12 tooth max toque clutch 🤔

@black66 I have the same minibike and just ordered the exact adapter. What’s the biggest sprocket you can put on it ? And I’m using a 12 tooth clutch and just bought a 62 tooth sprocket with a ratio of 5 to 1 is that going to be hard on my clutch?

Another great video sir, and as far as the sprocket goes, does it to be mounted a certain way? I noticed you had the numbers facing outward, thanks for posting ride safe.

What mini bike frame is this and wheel size

What size of chain you have on?

Hey, what half-sprocket did you put onto the universal sprocket adapter? And what size/ thread of bolts did you use for the sprocket? The funny thing is I have the same Doodle Bug mini bike as you do! And where did you get the chain holder at the bottom of your mini bike?

Where can I get that chain breaker

Hey love the clips what's the app ur using to record ur speeds

What's done to the engine?

What app are you using to get your times and speeds? Or if anyone else has any suggestions?

what chain breaker is that? ive been looking for a solid one that doesnt destroy the link

Luv your video! what is your favorite bike setup?

Hey man I had a question, would a stinger exhaust pipe fit a doodle bug blitz mini bike?

looking to purchase a tilly 212 for my doodlebug now with stage 1 upgrades and gov removal. what do you suggest for a good gear ratio?

I just got a yellow doodle bug

I still need to know what pilot jet you have in the nibbi.

I got this exact adapter, but when I tried to bolt it on, the core screws dug into the frame, so I put a washer in, but now my brake is unaligned! Any idea how or why mine won't fit or how to fix it? Yours appears to have fit just fine with plenty of clearance for the bolts, and I have the exact same bike as you as well!

Where did you get the sprocket and bolts

What header pipe is this? Thanks

Putting a predator on my big now, what I’d the best way to line up the clutch and sprocket?

Damn!

What chainer spliter is that? I seems to work better than the chain molester i have

35 or 40 chain

What engine do you have on that

A lot of people are thinking that you can make your bike do this without having that same engine that you have not going to happen unless they have something like it or maybe bigger my five horse Brigs isn't going to do it
