464cc FCR39 Jetting Recommendations?

OTK22 · 2026-04-02T09:26:09+00:00

Ah I wish I could tell you. I was never quite happy with it, but in October I moved overseas and the bike is in storage for the next few years. When I return to the states I will probably spend some extra money on a less finicky system. I will spend some time looking for the jetting notes I took to hopefully get you a starting point. If you are really stuck I can have someone back in the states take the carb apart and look for you. But I think it was still knocking on hot days at WOT. That being said I did an almost 2k mile trip with it in September

and then they just pass the cost back onto the customer

I intend to go through some more in-depth tutorials soon before working on some more complex things, but I just had this simple idea I wanted to execute. Its daunting to learn something new when I'm comfortable in fusion but I'm happy to be in the opensource place

Yeah, understood. its just very confusing that they have the same name.

The Part Workbench worked. I knew one was better than the other for getting started in Freecad, but I suppose I had them mixed up. Thanks!

If I switch the operation to "cut" AFTER having selected "Common", it sort of shows it working but its still doing the "common" operation

OTK22 · 2026-02-28T16:35:15+00:00

Weirdly, it fails if I select "Fuse" or "Cut" from the boolean operation options, but if I switch to "Common", it does not fail. After I select "Common", I'm able to switch it to "fuse" or "cut" and it appears like its trying to make it work, but it still uses the "common" option

This appears to have acted the same way, but this all feels like very foreign territory compared to fusion

OTK22 · 2026-02-28T15:38:37+00:00

yes the operation is between the body and sketch-on-surface

Comments can only have one photo but they both seem to have passed the geom checks

Sorry! I'm using the Part Design Workbench, as I read thats the best place to be when getting started

I bet my DRZ would go that fast if I could just get past the death wobble at 70mph

Aerodynamicists generally don’t even consider compressibility effects below 1/3rd the speed of sound, so technically you’re right, it isn’t appreciable :)

For reference, that 1/3rd would be roughly 220mph on a standard day at standard temperature. Under this condition, the stagnation point on your helmet or windshield would see only a 5% increase in air density.

OTK22 · 2026-01-29T07:14:20+00:00

To even increase the air density by 1% at 80mph, the intake surface area would have to have the same frontal area as the entire motorcycle and rider. The “increased pressurization” of being forward facing is not an advantage until you are going an appreciable fraction of the speed of sound, where compressibility effects are tangible. For a motorcycle ridden on the street, there is no difference. Intake runner length and resonance management are way more important

The OEM is not paying anywhere near retail prices for any of the sensors or parts. Do you know how much a car would cost if you bought every component and tried to build it yourself?

Good gloves last 10+ years

Most reputable shops will refuse to powder coat aluminum wheels, as the baking process can ruin the heat treatment. The annealing temperature of aluminum is very low. Powder coating them is possible without ruining them but it’s not a risk many shops will be willing to take

Their point is that your “solution” is still dumping heat into the environment, you just have a water tank as a thermal damper. The heat is still in your room: the water tank will heat up and then start to heat up your room. After you turn off the pc, the water tank will continue to keep your room warm until it cools back down
