For what it’s worth, these Predator engines are fantastic! The Baja Doodle Bug doesn’t get the riding attention it once did and will sit for months at a time in our shed at our cabin. The bike will ALWAYS start within 3 pulls and performs exceptionally well every time. I would recommend gas stabilizer if your engine will sit for extended periods but after a lot years, my bike still performs like new. Thanks for the continued positive feedback and I hope that others are enjoying their mini-bike like I have. It’s pretty cool to be #1 when searching Baja Doodle Bug on TH-cam. Thanks to all my followers!!
Predator motors are a direct copy of the Honda GX engine design, that’s why they are so awesome.
I LOVE THIS VIDEO!!! No many how many others I watch, this one is still the most in-depth and helpful I've watched!! I go back to this every time I need some help because you explain everything SO WELL!!
Great Video I wish most how to vids were as informative as this one I realy enjoyed it and learned alot from it Great Job and thank you for takeing the time to share your experiance with us .
I got the same minibike for my son with the same lil gutless motor. I got the 212 hemi and put stage 3 mods. And did some sprocket changing. 52 mph according to GPS. I also took out the governor. Oh and put on shocked forks for a smoother ride. On the front only that is. Lol. But it keeps tbe front tire on the ground better like a strut s does for ur car. Nice vid bro. Plz be safe. But HAVE FUN DOING IT..!!
did you have to change out the “ rear “ sprocket to a different size ?
Just slowly watched your video😊 Awesome Video on the "How To" Very Informative and step by step makes it easy for anyone to follow and replay over and over throughout the whole step. Big Thanks, as I will getting to work on my sons Baha Racer and 212cc engine swap and a new militarized look and theme with headlights and tail lights.. Thanks Again😄
I have been looking for this EXACT video!!! Thank you sooo much!
great video! i just picked one up and im excited to do this!
I’m glad you showed how to install the shutoff switch on the handle bar , I am doing it now , also I’m upgrading the pipe and air filter and Possibly the valve springs
Awesome video! Great information too. Well done sir...
nice work man
That turned out SWEEEEEET. I have an oldschool DBug, red, & a newer Motovox MBX 10 ... all stock though. I don't feel the need for an engine swap because it IS a minibike afterall. The paint and other changes though, now that is something I may do to the old DBug. Great vid!
Kick ass, Great job and thank you for posting..
Looks very nice!!
Good video I just purchased a doodoo bug three weeks ago ima buy a predator 212cc with all the mods
awesome job man very cool you gave me an idea thanks brother
Awesome Video! This helped so much!
thanks for this video it helped out alot for linking the kill switch when I got my new preditor engine!
Great video. Thanks for the details.
Nice and informative! Great vid!!!
nicely done 👍
Great video, a lot of information!
Great video helped a lot on my doodle bug project :)
I redid the Coleman ct200u with the 212cc ten tooth clutch and 50 tooth rear, it only does 22 mph but I built mine for off trail. I live in Oregon so I need more torque then speed. Looks great.
Looks good. Wish I had one.
this video really helped me build my bike it almost looks identical to urs the only problem im having is the clucth tearing my shoes and pants up i guess i will have to fabricate a cover at work but nice job on ur build can't wait to post my vid!
I'm glad to hear your project went well! It's way too hot in AZ to even wear pants, so I can't say I've ever had the issue of pants getting torn up by the clutch. Just to verify, you have the sprocket portion of the clutch facing toward the motor, right? I'm not sure the chain can line up correctly if you had it turned around but that might explain the issue you are having.
For simple options, They make straps that attach to your pants and go under your shoes to keep your pants from getting caught for regular motorcycle riders. You could also get a Velcro strap to wrap around your ankle area to keep the pant legs secure.
Drive safe and have fun!
Yea i have the sprocket on just the way u have urs and believe me im from Houston TX and it gets pretty hot over here but i work at a fab shop so ill figure something out to cover that i will pass on ur video to other mini bike builders greetings from H-Town!
Great job
Okay - using the speed trap systems to measure your speed was brilliant! I'm still laughing about that!!!
Lots of information! Great video - just started my Baja Doodlebug/Dirt bug project - Uploaded the first video today
Nice I'm doing the street bug on my other channel
I just got one myself. The only thing I didn't no was a lot of the parts are discontinued , and they stop making them. I'm really upset about that. I've been looking for places of where I could go to get some part, Nothing! Very nice work you put into it.
SUBBED!! thanks for posting!
Good job!
Very Detailing video 📹
Awesome video bud 👍🏼 Thank you for your time and advice it is much appreciated!! oh hey what kind of bike is that in the garage?
Best how to video
Outside of California, use Harbor Freight engine #69730.
i love the makeshift radar guns lol
That's looking pretty sweet, but just a word of caution on your grip installation technique from a bicycle mechanic, use rubbing alcohol or hairspray instead of soapy water. If the grip gets wet again it can cause the dried soapy water to unstick and your grips will slide right off.
I had a Baja warrior 200 cc and I converted it from chane drive to a belt drive and after that I could do 60 65 perfect trail bike I'm 5" 6 5" 7 160 lbs
Sweet doodle
Generally, a chain will only come off if there is too much slack or the sprockets aren't aligned well. Have you adjusted the chain tensioner at all?
nice video
Although it's a pretty tight fit, there is room to remove the gas cap and fill the tank with gas. If you have a gas can with a longer, flexible spout it makes it easier.
nice job doing the same at the moment
The mounting plate was smart I was about to buy a drill to make it fit but ima but the plate so I don’t have to drill
great video.. i would like to make this mini bike
Great job nice build I have the same frame and im going to buy a motor for it the same motor you have, where did you get the centrifugal clutch and brakes & rotor... Nice work
What a great video.. Thanks for uploading... Any links for parts on this bike.. Just started a project of this bike...
I had something that looked like that in the 70s.i think the brand was called taco.
It was purple and had a white seat.
Wish there was a gas filler cap mod. I did this a few years back but still find it difficult to refill the tank.
Looking at the fuel cap being so close to the frame and seat, how do you remove the cap and fuel the tank?
Did you have to drill new holes for the adjustable mounting plate ?
What gearing is on this bike? Im doing this to my db30 and the engine is hopefully getting here this week
I leave me rear tire low it acts like suspension😂 lol
+Tony Hughes - search google for PMR MOUNTING PLATE. It's the 1st listing.
Might use a heat gun to remove the stickers off the fenders. The heat softens them and they just peel off by hand.
What clutch are you running? I'm 220lbs and mine shakes like hell on acceleration, I feel like it's the clutch struggling to lock up, but it's also a cheap clutch.
I put a hydraulic caliper on the brake on mine. Really worth doing.
I've always wondered whether the single disc brake in the rear is enough to handle the 212. Can you tell me more of what you did and how? A video would be awesome.
Awesome build! i just got a DB30 myself givin to me, unfortunately the engine and clutch are beat up pretty bad. i want to do the predator swap aswell.. i went on harbour freight website and theres 2 different model #'s for the 6.5 212cc engine. do you know which engine you got specifically. was it the part #60363 or #69730? thank you in advance.
That guy - If you don't live in California use engine 69730. Enjoy!
i live in so cal , i guess i need the 60363
Is that similar to the Coleman u100 or 200, I am having trouble fitting my 212cc gas tank
Great video ,nice job ,but please don't let your kids ride in flip flops.
I still have the original 97cc and the bike rarely gets used. I'm wondering if, after upgrading to the 212cc Predator, if the single disc brake is sufficient for the additional speed?
I kept the original brake installed without any issues. I’m sure there’s upgrades but I never did one.
That engine should have sae-30 (somewhere around there)
GREAT VIDEO BY THE WAY , I looked through all the comments but didn't see my question , looking for a factory replacement seat cover , I heard you say you put one on , please , where did you buy it ,I'm having a hard time finding one. by the way , I'm just starting the same project , motor plate seems like a good idea , thanks in advance.
Scott F I bought the replacement seat cover from Etsy.com (I have my full parts list in my description). Thanks for the video feedback.
thank you for the fast reply
Does anyone know where i can get chrome fenders for the doodle bug?
Is a engine mounting plate needed for this swap?
Can you mount a 212cc directly to the doodlebug without the plate? What are the reasons for the plate?
Pyro Nurse You do not need the mounting plate but it is highly recommended. The doodlebug comes with a very thin bottom plate attached to the frame and an additional thicker plate that is also installed for support. The holes on the thicker plate do not line up with the 212cc motor so it cannot be re-used. In addition to the stability that is greatly increased with the PMR mountain plate, it also provides bolt placement adjustments which helps to make aligning the sprockets much easier.
what size mounting plate did you use ?
I have the same set up but I didn't get the mount plate I drilled my own holes the chain is straight to the sprocket and clutch but the chain keeps coming off when full throttle at first or while riding. Any ideas why ?
K20xOG x check chain aligment or give it a bit of slack..
Will a 3/4 bore and 12 tooth for 35 chain clutch work with the stock rear doodle big sprocket?
SeanFilm Yes, no need to replace the rear sprocket.
I had to put another cable spring on to get better back rpm..20:30.
+ELVISRN1 put a torque converter if you have a few hrs. you will be impressed. great vid!
Flip flops and shorts...
Lol a must for testing purposes
Wer Where did you buy the clutch where you order it
Great video but how hard is it to get that gas cap off?
Muhammad87 Others have asked the same question. It is less complicated than it would seem. Filling the tank requires a longer flexible gas spout to avoid spilling excess gas on the engine. Thankfully you get a lot of riding before needing to fill the tank again.
Great work!!! Where did you order the engine mount plate and the clutch?
Bill Gordon The parts list is located in the description. It has the info you are looking for.
@@zach_wolfe Thank you Zach! I'm in Phoenix and just found a doodle on craigslist. I'm going to do the same thing you did. Thank you for the great video! and its very helpful
Ah yo can i gets that old 97cc motor
plz ask me which company engine????
I just restores mine to it's kinda original color
Will the original chain work or have to get a different one?
You will need the new chain. Original is too short with new motor.
Do you know where i can find tires? The one i have is completely bald, i can't even see the markings.
The stock tires are 15x6. I replaced my worn knobby tires with smooth lawn & garden tires from walmart.com for around $18 ea since my riding was exclusively on pavement. If you still want knobby tires for dirt and off-road, then search for knobby 15x6 tires online. Happy riding.
Can you use a toruq converter on it I have a Baja DB30 D bug
Yes but you have to cut the tensioner off and if you wanted to you can put it back on but back farther
Could you please provide the info on the mounting bracket you used? Model and where you got it. Thanks.
+Tony Hughes - All my parts are listed in my description: PMR motor mount plate, drive shaft spacer w/clutch mounting bolt and throttle linkage kit = $66 shipped (hotrodminibikes.com)
+Zach Wolfe Is there only 1 size/model of the PMR motor mount plate?
I have a raceor and it is fun to use but the engine is messed up, if you have a enggine could i have it. My engine is pretty much shot by this point.
I don't have any extra parts, Trevor. If possible, save up and upgrade by following my video for guidance. Turns a fun toy into a beast of a machine!
you still have mini bike
Does anyone know where I can get that mounting plate? The website the he mentions is no longer working. Does anyone know the name or size or link?

Where can i buy chain tensioner for 97cc Baja doodlebug ? Any help ? Please & thanx.
Rick Osborne Amazon 97cc use the same as motovox and 80cc monster motto
where can i order the clutch from the required clutch for that engine please help
Richie Da Topshotta, All of the parts are listed in the description including where I bought them. Enjoy.
I live in arizona too, can you ride mini bikes around in your neighbor hood?
Snubz30 Motor vehicle laws apply to neighborhoods as well. That being said, if you ride around your neighborhood without being a nuisance to your neighbors, MOST people will not have an issue with it. In my experience, most people (usually kids) that have motor driven toys (mini-bikes or Go-Karts) drive way too fast, make too much noise and have no regard for neighbors. Me and my boys would ride this Doodle Bug for miles throughout our neighborhood on a regular basis without a single issue. Again, HOW you ride and how often you pass the same neighbor’s house will most likely determine if anyone has a problem with it.
Zach Wolfe ok thanks for the info
Where’s part 2
5:22 I see that engine plate it was in other vids too do you reuse it ? what is it used for?
1digitalwatcher The small engine mounting plate that comes with the original engine does not work with the Predator engine upgrade. You’ll want to order the PMR mounting plate as listed in my description with parts. It adds stability and easy frame mounting for the new engine.
@@zach_wolfe Ok THANK YOU I got to order a lot of stuff been reading and reading on here !!
I found every thing but the stuff in the hotrodminibike website I don't understand what to get could you put down links or something?
PMR mounting plate:

Throttle linkage kit: (As noted in my video, this part is unnecessary. The Predator motor has all the necessary hardware to attache the throttle. However, I did hammer the 2 angled pieces flat in order to raise the chain guard)

Zach Wolfe thank you so much
looks like it would be hard to get to the gas lid to add gas. is it?
It's really not bad. Using a gas can with a flexible spout makes it easier, but the gas cap is not difficult to get on & off.
+Zach Wolfe thanks for the reply. I'm working on the same bike and you did a great job on your. hope mine turn out just as good.
Did you use the same chain that came with orginal motor, plz let me know asap thank you.
No. The description has all the parts I bought, including a new chain from eBay.
Oh ok thank you very much
As long as it's a #35 chain I should be good right?
Make sure it's a 140 link chain. It may not fit if it's smaller.
+Zach Wolfe ah ok thanks
did you need to drill holes through the bottom of the bike to get the bolt to go through the engine for the motor mounts???
Yes. The mounting plate comes with instructions but you will need to drill holes.
Zach Wolfe oh do you need the mount plate or can you do it without it?
+Jacob Kenyon You don't need the mounting plate but it makes aligning the sprockets very easy. The mounting plate allows for engine placement tweaking. If you mount the motor directly to the frame, there are no adjustments that can be made.
ok so is it worth it to buy one??? like if i put a 212 would the chain always be poping becouse my doodle bug i have adjusted so would the chain just pop off without it? or would the clutch and sprocket not be aligned
+Jacob Kenyon For the $40 or so, the mounting plate is worth it. Provides engine stability and alignment benefits.
How many teeth on the clutch sprocket? 11 or 12?
3/4 inch, 12 tooth, #35 chain Max Torque clutch
Okay thank you
100th sub!
That's what I did
does the clutch come with the new engine?
The clutch does not come with the engine. You need to buy it separately.
Hey can u tell me what size chain is that
Paul Burnside All my parts are listed in the description. It's a #35 140-link chain. Got from eBay for about $12.
Where did you buy that frame
Der Kritiker: As mentioned in the video, the Doodle Bug was a gift from a friend. They can be purchased new from stores like Pep Boys. However, I recommend looking for a used one at garage sales or "for sale" sites online.
Where did you buy the motor?
Harbor freight.. You can get coupons on their website and get the engines around 100 bucks
