Manco dingo 285 build help

[Jackshaft01]

Hello everyone. I have been reading these forums for a couple years now but recently joined. So thank you all for the knowledge you have given me.
My question is regarding my new to me manco dingo. I’m torn between buying a ghost or pulling the motor out of my mini bike.
I have 301cc predator with pod air filter, jet upgrade, aluminum flywheel and torque converter (30 series)
I’m not sure what this motor is pushing but it’s fairly fast.
From watching red beards garage the ghost is pushing 9ish hp and 10ftp torque.
From what I can tell the ghost and my 301 should be close. Looking for input would the 301 Be better. Or would ghost and juggernaut tc smoke my 301?
Thanks In advance

Welcome! Speculation is for spectators. Just do it and find out.

How did you get a 30 series on a 301?

I have a hot 301 on my manco dingo with a 40 series.
It puts smiles on the face of who ever is pusing the go pedal.

I wouldn't waste my time with a ghost.
You can put parts in a 212 and make more power for less money.

Same with the juggernaut. Unless your making big HP its just not necessary.
Dont fall for the marketing hype.

The 212 is a small block and a 301 is a big block.
Different mounting plate size.

Im not sure on your exact model but the bigger dingos came with big blocks from the factory.

Thank you for the input! They sell a 1” diameter driver for the 30
Series. It’s not the best, I can tell the motor has more power then the driver can handle but it does fairly well. I have it on a bt200x right now. It is a wheelie machine.
only reason I’m considering ghost is because torque and hp are on par with a stock 301, smaller and lighter build and I don’t have to tear down my mini bike.
I considered the 420 but im trying to keep weight down. I travel a lot so it will be loaded into pickup truck bed mostly by myself.

Not exactly sure what you have but beware of the pod or cone filters that are sold with the “Stage 1, 2 and 3” kits. They are woefully inadequate we have come to learn. They filter so little real dust and particulates that they’re essentially a bug filter. They must’ve been intended for track use where most of the debris is shot sized bits of rubber or for the most sterile of environments (rain soaked streets or ice racing?).

That being said, the 286/286 Dingo frame transforms well into a parking lot racer.

We have a stickied thread somewhere about using a good filter and the hard lesson of not doing so.

Thank you for the reply. I had no idea those filters were junk. I’ll try to find the thread. Side question it seams like I lost a lot of torque after installing a slip on muffler, is that normal? It’s a quality muffler for gps (301cc)

Use a good air filter

@Hellion mentions it all the time, as do other members BUT make sure you research and find a sufficient filter for the environment you drive in. Those "stage 1" filters are literally useless. Here's the filter that comes with the "stage 1" kit from Gopowersports. It's maybe 10 hours in a pretty...

…but the bigger dingos came with big blocks from the factory.

He’s right you know.

The larger Dingoes (389, 390 series) came with big block engines but the frames were designed around those bigger engines. Back in those days though, they were flathead engines which have a smaller footprint than a modern OHV engine of the same HP or displacement rating. Part of it is due to the flathead’s vertical cylinder orientation. Modern OHV engines have their cylinders canted over, nearly horizontal, so they take up more room on the mount plate but I think the main culprit is the Predator fuel tank. You’ll see re-engined Dingoes with the fuel tank removed and mounted on engine risers or up on the brush guard (aka “roll cage”). I’ve seen worse, with much larger aluminum “beer keg” tanks mounted well above the engine. A (full) 5 gallon tank mounted 2 feet above the engine gives me the willies. That’s a lot of weight high up…

I have a 286 Dingo and the good old Derp 212cc just fits with about a thumb’s width of space between the seat and the engine. I don’t know the exact “geometry” but there’s fitment options if you use a factory-style jackshaft mount since it can raise the engine up about 2-3” and then you can move the engine around a little, fore and aft so you don’t necessarily have to break out the Sawzall and customize the frame. I think that!s what you’re looking at here, a jackshaft assembly.


Thanks E.S. for the link. Doing a forum search through the sheer number of posts here plus the multiple subforums is a bit daunting. The search function isn’t foolproof either.

Excellent information thank you!
I will be working on the dingo this Easter break ( got 4 days off work) playing on installing my stage one 301cc already ordered new motor mount bought some steel and have the welding machine ready. Hopefully it goes smooth and fits well. If not I’ll just pick up a 212 and slap it in there for now.
I’ll get some pics when I do the build and post them for ya. Thanks for all the help!

Your 301cc motor is already plenty fast. The Ghost might be a bit more reliable but if your 301 is tuned well, it should perform just fine.

 

[Jackshaft01]

Got motor mounted today!!! Still need a few extra bracers just to make me feel better but she’s on! Took her for a short Ride around the rv park and I can tell you that the 301 is perfect. Even with both back tires flat she was spinning wheels. Gonna switch out tires and put new tubes in the back tomorrow and tweak the breaks. Will update.

 

[Jackshaft01]

Finally got her road worthy today. Took her to the beach. Roughly a two hour ride down the beach. It did amazing went thru loose sand, did doughnuts on hard sand and performed amazingly. The 301 is perfect for this build. Enough torque to spin tiresand get sideways at about 15-20 miles an hour. I hit around 36mph on the strait away. It had more but rpm’s were pretty high already didn’t wanna push the ol girl. Massive amount of torque. I might switch out the 10tooth for a 12 see how she does.
Thanks to everyone who helped along the way.

And you barely even got dirty! Love a good success story.

Alright boys need some advice again…
Same 301cc runs great, kinda. If I push the throttle like a normal person it runs fine. If I stomp the throttle it bogs and dies (from idle). I’m thinking pilot/low rpm jet. I’ve tried switching main jet to larger size but has a negative affect(bogging/dieing). Second hand motor so not sure what if anything has been done to idle jet. Any thoughts?
