I'll check out the TC while the engine is running, I also feel like that's what it has to be. Maybe I over tightened the driver pulley causing engagement at 0rpm? Because I'm pretty sure I assembled it in the right order. Maybe they sent a belt that's too small for the pulley distance? As for...

Pedals spun a dual-sprocket hub attached to the frame, which acted as a coaster-brake freewheel, which then connected to the sprocket on the axle (which is fixed itself). So you could pedal forward, coast, coaster brake by pedaling backwards. Axle bolts to the right drive wheel with a square...

Hey guys, I wanted to update you all. The trike is complete, just took it downstairs and locked it up outside. I am facing some issues though and I would love some input. Any help is appreciated!!! The trike is right wheel drive only, and the right wheel refuses to move unless the engine is...

Nice, and it's definitely the method that requires less work and money. I think I'll build it like that and keep an eye on it at first to see how the platform is holding up. If I see bending/deforming, I'll cut it and mount to the tubing. I doubt it'd just fail without warning. Thanks!

Some pics of how the engine placement will look. I need some advice about where to mount it to though. The engine mount/jackshaft body is 1/8", 0.125" (3mm) thick steel, so 11 gauge. The platform of the tricycle is only 0.09" (2.3mm), 13 gauge thick steel. The tricycle is rated to support...

Haha sounds like I've been overthinking it. Thanks! How about additives? Any to fuel or to oil? Stickers all over the engine said to use fuel additives? But I almost feel like that's for storage? I plan to use it daily, do I need any break in or fuel additives?

Hey guys, I ended up ordering everything and it's slowly trickling in. Final parts should come in end of this week, start of next week. I'm gonna start assembling everything this week. I just had some questions about oil and gas. I did some research so this is what I'm planning, please correct...

Nice, I'll start looking for one. Thanks so much for all the help guys =). I really appreciate it, I was really lost before this lol. I feel like next step is to start buying parts and building. I'll shoot an update as things get moving =) Plamen

Awesome, thanks! I'll definitely save those videos for a few months from now when I do that =). Ah =/ I had assumed the extra length would quiet things. In that case is there any way to make the stock muffler quieter??

So adding an exhaust/muffler also increases the air intake? :huh: I'm not looking to add anything to the engine except an exhaust and muffler. All the other performance stuff like filter/intake, springs, and jets I plan to do later once I have more monies =p. For now I just want it to be quiet...

Are you saying that if I install only an exhaust header and muffler (no air filter,l or springs), i would need to re-jet the carb?

All 3 tires are the 26 x 1.75 solid, airless tires that Worksman carries. Worksman have a 26 front, 24 rear unless you go for the airless tire or mag wheel upgrade, then all are 26. Currently it's a bumpy ride and that's only at 5-10mph. I'm cutting them off soon and switching to 26 x 2.35...

Gotcha, so the TC I'm getting comes with a 12t #35 and 10t #40. I'm also getting a 12t #40 5/8" bore sprocket that I want to put on the TC instead of the 10t. Then off ebay I'm getting a 36t and 12t 3/4" bore #40 for the jackshaft, and finally the 36t #40 7/8" for my trike axle. Does that sound ok?

Your replies have been awesome, thanks guys. I used the calculator. With a 12 engine to 36 jack in / 12 jack out to 36 axle I get 9.0. With what you guys are saying that should be a safe bet? It would also allow for cruising 21mph @ 2400rpm (peak torque @ 2500) and maxing out at 33mph @ 3800. I...

Mckutzy thanks so much for the responses. Can you please tell me if I'm off base or if this is realistic? I was thinking I could avoid using a massive 72t by throwing a jackshaft into the mix. Could I run the drive sprocket from the torque converter to a dual sprocket on a jackshaft, then run...

Measured the axle to be 22.2mm or 7/8". This video has a great undershot of the axle/drivetrain at the 1:00 mark https://www.youtube.com/watch?v=C4Yyt3u9kkY&t=1m Crankset seems to connect to a coaster hub, with a fixed cog on the non-drive side. Then the fixed cog on the hub connects to the...

Hey guys, I'm building a Worksman Adaptable tricycle into a motorized trike using a 212cc Predator 6.5hp engine I have a very thorough knowledge of bicycles, but pretty much haven't got a clue about engines apart from the basic mechanics of how they function. I'm getting a Predator from...
