- Doodlebug minibike sprocket adapter install and top speed
Installed a universal sprocket adapter on the Doodlebug/Baja racer mini bike
Installed a 66-tooth sprocket and then compared it to a 70-tooth sprocket with a top-speed run.

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
Thanks! Ya, the Doodlebug is pretty sweet!
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
Thank you! Thanks for watching!
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!
Thanks! Thanks for watching
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.
Thanks! Ya, the split sprockets definitely make things easier.
Nice comparison!
I’m working on a Doodlebug right now!
This is insane
That was quick
what chain breaker is that? ive been looking for a solid one that doesnt destroy the link
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-
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
What app are you using to get your times and speeds? Or if anyone else has any suggestions?
is that a 12 tooth max toque clutch 🤔
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?
What size of chain you have on?
What mini bike frame is this and wheel size
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!
Thanks! Doodlebugs are nice bikes! I try to run RLV Gold ON Gold if I use 35 chain. I have used quite a few different combos on this bike. Check out the Doodlebug playlist. Thanks for watching! th-cam.com/video/j39zPwFQOR8/w-d-xo.html
That split sprocket is the only way to go .
Putting a predator on my big now, what I’d the best way to line up the clutch and sprocket?
The best way I know how to get sprockets perfectly aligned is using a string you tie the string tight to one side of the clutch sprocket and then pull it back just beyond the rear sprocket and when you go to lay it on the side of the rear sprocket you can see if the string hits flush at the same time or is off
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?
5 to 1 or 6 to 1 is a really common ratio .But It really depends on what you want the bike to do. If you want it quick or fast or somewhere in between. I have used many different ratios on this bike and others on the channel. Check out the playlist. Thanks for watching! th-cam.com/video/j39zPwFQOR8/w-d-xo.html
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.
There is a mark on each half of the sprocket . You line up the marks so the two halves go together the right way. You can put it on numbers in or out
Where can I get that exact adapter? I have that same back rim and tire. Please help
GoPowerSports has the exact adapter
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?
Sweet bike! It's hard to remember what I did in some of the videos that far back. Check out the Doodlebug playlist. I have since stretched the bike and have done numerous parts tests and engine swaps. th-cam.com/video/pZ3Tw27R-5A/w-d-xo.html
Where did you get the sprocket and bolts
I put the links for both in the description of the video. www.ombwarehouse.com/doodlebug-sprocket-adapter-4.html
I still need to know what pilot jet you have in the nibbi.
I'm running a 38 pilot but that could be different on yours because of the altitude I'm at and engine mods.
@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?
You can pretty much us the total range of sizes . Rider weight makes a big difference of how hard the ratio is on the clutch.
Hey love the clips what's the app ur using to record ur speeds
Thanks! I use digiHUD on the phone along with the camera GPS for top speed and a Dragy Performance meter for 0 to 30
Hey man I had a question, would a stinger exhaust pipe fit a doodle bug blitz mini bike?
It will fit on the doodlebug with an aluminum motor plate to raise the engine and bending down the hoop on the back of the frame a little.
Thanks for the quick response! I've only had my mini bike less than a month & don't really know too much about them so I had to ask an OG!
I was told that my Mini bike was a Coleman ct100 from the guy I got it from, but after doing research & seeing a lot of your videos, my mini bike is a doodle bug 70cc blitz mini bike with a predator 212.
I want to have my forks & frame candy painted do I have to heat up the metal bracket to bend it or?
Luv your video! what is your favorite bike setup?
Thanks! This bike is one of my favorites. Just the right size for me and a lot of room to work. They are all good in their own way.
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!
Thanks! I use digiHUD on the phone along with the camera GPS for top speed and a Dragy performance meter for 0 to 30
What chainer spliter is that? I seems to work better than the chain molester i have
It's from ARC racing
The ARC racing breaker isn’t cheap,but we’ll worth the $$
$30-$35 and works smooth as butter 🧈…
The one i got alway trashes a link no matter what and it was 20 bucks ... so for the xtra coin its worth it compared to the one i got ruining a good chain just once
Oh man,, DEFINITELY.. I’ve done that tons of time. I buy based on price to save a few$$ and end up buying a tool twice.. Get the ARC one, you won’t be disappointed. It’s a really well made tool and it won’t ruin a new chain..Let me know what you think if you get it.. Ride fast. Ride safe..✌🏼
What header pipe is this? Thanks
Here is the link www.ebay.com/itm/262974643153
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!
did you figure it out? mine does the same too
@555PAUB KOJ Yeah, I ended up adding a bunch of spacers until it fit. I have no idea why it wouldn't bolt on normally...
what size spacers did you use
Where can I get that chain breaker
The links for the parts used are in the description of the videos. Check out the Doodlebug playlist for more combos with this bike! th-cam.com/video/SuBNz0jH5pU/w-d-xo.html
What's done to the engine?
Check out the doodlebug playlist. It has had many different engine combos th-cam.com/video/SuBNz0jH5pU/w-d-xo.html
Damn!
Check out this one...th-cam.com/video/xV8i59aGUao/w-d-xo.html
I just got a yellow doodle bug
What engine do you have on that
The Doodlebug has had quite a few different combos and engines. Check out this playlist th-cam.com/video/JIHHuNigHy4/w-d-xo.html
@@Black66 okay I'll watch the videos I have a doodlebug db30 have had various engines on it I've ridden it over 2,000 miles in the last year and a half
@@williamedwards7315 Awesome! Doodlebug is a nice bike!
@@Black66 just had a 98 big block 7 horse Briggs on it blew up yesterday clonked out now I have a 2005 five horse Briggs still the old style engine currently I have a 12 tooth centrifugal clutch running to a 70 tooth rear sprocket I have another rear sprocket that is a 36 tooth what would happen if I put that on the back with a 12 tooth clutch?
@@williamedwards7315That is a 3 to 1 ratio. I don't think the engine will have the torque to pull that much gear, especially if you have 15 in tall tires. It will run but it will turn very low RPM.
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
35 or 40 chain
This one has 35. When I use 35 chain I usually will run RLV GOLD on GOLD Like on this bike...th-cam.com/video/xV8i59aGUao/w-d-xo.html
