CRX HF reverse trike project

That gas tank should take you about 1,000 miles or so

Double check with others for precise angles and whatnot, but I'm thinking this is about what you'd want to do..



Angle your "horizontal" flat piece up at the back, from bottom of car seats to about 2/3rds up the back of the tire. Approx 12*?

Then for the bike, 'channel' out about 1' wide, and build vertical walls down. The idea is to flow the air smoothly under the back end, while channeling air around the tire that sticks out.

That would be easy to switch over have the clutch pedal to engage both clutches at the same time. Turn one off turn one on heck turn them both on for fun

Thanks I will use this info when the time comes.

I wouldn't worry about using both the motorcycle engine and the CRX engine. That would create extra chain drag or driveline drag when the other isn't engaged. And besides, burning gas is still burning gas. A bike pushing around a CRX&motor wouldn't do much for mileage.

However, if you consider adapting a golf cart motor into the motorcycle frame, adding some batteries strategically for weight distribution, and jackshaft it appropriately, you could use the electric drive for up to ~25mph, then CRX on long drives. When the electric is engaged, keep the CRX idling to keep power brakes, etc and to charge batteries. There's the box, then there's thinking outside of it..

Play around using this Calculator, it's based on gas motors and go-karts, but figure approximately 3000RPM from a golf cart motor, and figure out your actual wheel circumference. Just goofing around, I tried a 24/64 and 24/64 jackshaft ratio at 3000RPM and it gave 25.97MPH.

Bad idea. You don't need power brakes on a CRX as it is, and they already don't (mostly) have power steering.

The net effect won't be a weight reduction, but it will be less brakes overall, and less tire contact surface, which means you want less leveraged force on the brakes to compensate.

Plus, burning a bunch of fuel to recharge the batteries is probably one of the least efficient ways to do that. If you're only using it for speeds up to 25MPH, you're probably also using it only around town... in the event that your (deep cycle) batteries get low, you can always start the engine and let it charge the batteries to get you home, or better yet, keep them out of that circuit altogether and drive home on gas, then grid charge the batteries like you should.

That 350ci reverse trike would be a great starter idea for a MPG build. Instead of a Toronado V8, use a Metro 1.0L. Stretch the frame back another 18" so you sit down in front of the rear wheel instead of over it, get out of the air flow. And I don't know about a single-sided swingarm, that sounds dangerous in a 2F1R.

Good video, makes my mind wander

If you've seen how that SSSA is designed, you'd probably rescind that statement.

In general, the SSSA is just as strong as, if not stronger than traditional "grapple" style swingers. They're usually over-engineered to deal with non-standard and non-linear stresses.

Little update
light seats 60.00

Have a old header I will try for the getting it on the road thing. Any input on a better exhaust? I know the pipe is big on it and the stock system would be better Any thoughts? 1.75 dia so not to far off of the 1.5 exhaust for the HF
