Part throttle sounds very lean. Or misfire. Or both. But full beans sounds pretty dang rowdy.

[@Fix_It_Again_Tony]

It's looking good. A couple heat shields on the exhaust to keep the mastery cylinder and oil cooler cool and maybe some tuning would both be good ideas.

Brake master/fluid might get a little toasty there!

The 2 strokes are hard to build in a power wheels because of the expansion chamber but I'm sure we will see one eventually on GHP!!!

[@Ameritude]

The first one ever, the barbie mustang was a 2 stroke 80, good times. It would be cool to see a newer one made though Edit: I guess I'm incorrect. I looked back and it was a crf 230... I could have sworn there was an 80 in there somewhere, owell

best use of a rotary ive seen in a long while!!! kudos

[@markdyck6852]

Grind Hard need to build a sweet golf cart with long travel suspension to actually use golf cart tires as intended

[@JV_214]

You don't need a oil cooler for the short runs that you do, they actually become oil heaters, lose that old 2 barrel carburetor and get a 4 barrel Holley set up for a rotary to wake it up, that 2 barrel has a small float bowl and is too small for that engine, a megaphone after that muffler will give it a different sound and fit well with the motorcycle theme

[@mattsez2879]

with the exhaust so open, id say up the jet size......might fix that popping and miss

"It's running better today for sure!" proceeds to have some of the worst cut out you can imagine. If I had to guess it's fuel. And if not fuel then spark. I doubt it's struggling for air. I'd still bet both our lunch money on carb jets.

[@garthpaul6216]

@@racerex340 Totally agree, I mentioned it a few video's back. I owned and raced a RX2 Coupe for 18 years, listening to this makes me cringe.

[@racerex340]

@@garthpaul6216 yeah, you can't hack your way through a rotary, especially when not fuel injected. Besides getting timing and fuel right, they're also super sensitive to intake runner length and exhaust tuning, more like a 2 stroke. Given that it looks like someone ported the irons, it's going to take that much more fiddling to get it running right. They should move to fuel injection regardless, that carb is going taunt them, no amount of jetting is ever going to come close to what they'd get with even a shitty failsafe map going EFI.

[@Onewheelordeal]

Seems like a good way to get caught on brush if this thing ever rips up a trail, tho I guess the rear wheels already do

[@bradleyober6196]

I thought the same thing. The outside of the forks seem like they could be beneficial to the steering.

[@damageincorporatedmetal43v73]

Awesome build man, you should wrap the exhaust. It adds to the performance of the engine & you can get it an array of colors. Good luck I enjoyed your video.

[@faran-]

Love because how unconventional it is, what a joy to watch you do such crazy/cool projects :D

[@davelowets]

Maybe building a collector on the header before the muffler, then running a single pipe back to a different muffler might give it some more power. I can't imagine there is much scavenging with the way it is now.

[@Gcrilla]

They may be unaware of the concept, now that I think about it. Is scavenging a thing on a wankel? Isn't each compartment isolated? So the exhaust drawing out wouldn't pull a vacuum through the cylinder.

[@davelowets]

@@Gcrilla Yes, they do have overlap between the exhaust and intake strokes in each chamber. Quite a bit actually, which contributed to their poor economy, and inability to meet current emissions standards. If the engine has any porting work done to it, the overlap becomes worse, just like putting a large cam in a normal 4-stroke engine. Proper exhaust scavenging will yield a big benefit on a Wankel.

[@Gcrilla]

@@davelowets that's awesome! I know very little about wankels honestly. If the overlap is like you say it, then a proper exhaust system would be hugely beneficial, also like you said.

[@davelowets]

@@Gcrilla Maybe they are unaware of it. I would like to see them rebuild the header, and see the power difference. I'm not a guru of Wankels, but I've built some nasty V-8's. I think with a better header design, it would definitely make a "seat of the pants" difference in power. With a typical built V-8, an open header collector with about 18" of pipe attached to it seems to be the sweet spot for the best average power production. There is an old trick of putting a longer pipe on the collector, then painting a white line on it, and then make a good pull with the engine. Where the white line quits burning off, you cut the pipe off there for best performance. That's where the "Slug" of hot exhaust starts to cool and the scavenging effect stops being effective, so any extra pipe after that would be a hindrance to scavenging. I've never done it on a Wankel, but I would expect it to work the same.

[@davelowets]

Have you considered if the exhaust heat will be intense enough to heat the brake fluid too much? So far it looks awesome!

[@myturkishlife1777]

It could be nothing but at 8:04 right after Eathen says "there we go" and you Rev the engine if you look right at the screen left of the old manifold something is arching.

[@patrickveal5435]

Something I think you guys might find cool for this trike is that they make a conversion kit for the H-pattern shifters that makes it a sequential gearbox. I can't remember the name of it right now but one company makes them to mounted remotely that you could modify to be used as a foot shifter.
