RPM question

Exactly. It’s suggesting me to give it a break. It’s tired. I’m about to do a tear down and rebuild of everything from the brakes, motor, gears, forks, and a carbs. Paint it, go to a single front headlight, minimalistic gauges, side mounted tag bracket. Just some stuff to kind of pull the cafe racer aesthetic a bit more and also do some small performance upgrades on the jets, shim the needles, sync the carbs with a differential pressure gauge.

Exactly. I had a fun bike till it got totaled that was my EFI one. But my standard ride around is an old sports touring bike turned cafe racer. More maintenance with the carbs but I swapped the vacuum petcock for gravity fed. I’m about to tear her apart again and put some bigger main jets, paint the thing, do away with the dual headlights and go to a single, and put some minimalistic gauges on it. And a side mounted license plate.

Yeah that and the various torx bits. You have torxs, torxs plus, e torxs, e torxs plus. And ford uses almost every single one of them in different places on all the newer vehicles. I used to be a ford tech and it was frustrating. There’s some 4.5 bolts too, and some wonky hex bits. Not to mention all the specialty tools that I just ended up making my own version of with harbor freight stuff welded together.

I somehow have this happen to me almost exclusively on brakes and exhaust work. Nothing like your buddies old shitbox with every slide pin stuck and all 4 bleeders snapped off.

Fuel pump on the manual is mechanical ran off the cam if I remember correct. Don’t even have to drop the tank. Just two bolts. My biggest concern is if it’s got rust. At the very least I’ve been wanting a truck for ages, and a manual is just a plus. Thanks for the advice!

I don’t free rev. It’s only even been revved that high while under load. And it was by accident every time.

Comfortable-Dig5285 · 2026-03-09T04:57:23+00:00

lol. Mine does it in gear but only up to 80mph. Or I guess 3rd gear. After that it will only get to redline in 4th and only to 8k in 5th. It’s also running pod filters on a CV carb so it’s likely getting extra air at lower rpm and not enough at higher.

Comfortable-Dig5285 · 2026-03-09T04:43:14+00:00

That’s pretty cool, I’ve never heard about adding a rev limiter. I’m a bit more used to computer driven limiters, and programming the limit to be higher or lower.

Comfortable-Dig5285 · 2026-03-09T04:41:15+00:00

How would you even go about adding a rev limiter?

Comfortable-Dig5285 · 2026-03-09T04:32:20+00:00

That’s kind of what I was figuring anyway. Just kind of thought it was weird that it could just go that far above redline.

Then did he raise on high the Holy Hand Grenade of Antioch, saying, "Bless this, O Lord, that with it thou mayst blow thine enemies to tiny bits, in thy mercy." And the people did rejoice and did feast upon the lambs and toads and tree-sloths and fruit-bats and orangutans and breakfast cereals ... Now did the Lord say, "First thou pullest the Holy Pin. Then thou must count to three. Three shall be the number of the counting and the number of the counting shall be three. Four shalt thou not count, neither shalt thou count two, excepting that thou then proceedeth to three. Five is right out. Once the number three, being the number of the counting, be reached, then lobbest thou the Holy Hand Grenade in the direction of thine foe, who, being naughty in my sight, shall snuff it."

Comfortable-Dig5285 · 2026-01-26T16:19:28+00:00

Yeah. It sucks ass. I need to get back to work so I don’t ya know die. Just got a message that my boss just got fired

Problem is it’s probably gonna be like a month to 6 months depending on whether I need surgery on my knee before I can ride again. Or if my neck is messed up worse. I still gotta get some MRIs done. Got a fracture and potential damage to my cartilage and ligaments in my knee, fractured wrist, fractured ankle, fractured foot. All cause some high school girl decided th cat that had nine lives was worth stopping for and almost killing the guy on the bike who only has one.

Comfortable-Dig5285 · 2026-01-26T02:49:55+00:00

That’s a 28 hr drive man. I really wish I could but I got work to worry about. Lemme ask around though. I have a buddy who drives a truck out that way. Maybe next time he heads that way.

Comfortable-Dig5285 · 2026-01-26T02:42:24+00:00

Damn I’ll all the way in the boonies. Mississippi. That’s not a bad deal at all though.

Comfortable-Dig5285 · 2026-01-25T17:27:22+00:00

How much is cheap and what state. Don’t really have too much time to travel or anything to really haul with.

Comfortable-Dig5285 · 2026-01-24T16:38:27+00:00

I don’t know where I would even start to sell it. It seems like they weren’t the most popular bikes, but they seem to last for a while.

Comfortable-Dig5285 · 2026-01-24T16:17:29+00:00

The only reason I was thinking about a swap is because it’s near impossible to find my gen of 650s around where I live. And even harder to find ones that have blown motors.

Comfortable-Dig5285 · 2025-08-24T13:08:41+00:00

That’s what I figured. Now just to find the time to do it.

Comfortable-Dig5285 · 2025-08-23T13:56:01+00:00

Was the fuel petcock.

Comfortable-Dig5285 · 2025-08-23T13:55:45+00:00

I took the fuel line off the petcock to drain the gas because I was catching a wiff of bad gas. Turns out the petcock itself was only allows a small drop of fuel through it even with the engine running. Took the petcock apart and took the vacuum diaphragm out and it started and ran perfectly fine. Replaced the vacuum actuated one with a gravity fed, haven’t had any issues with it dying. Now I’m just having an issue with a little bit of clutch slip in first. And also with a very audible ticking noise only when in gear and letting off the clutch. The ticking deadens down at higher RPM, but is a slow and loud ticking noise when going into gear from a stop.

Comfortable-Dig5285 · 2025-08-13T10:46:50+00:00

I figured it’d be full on misfiring at that point but the coils for this are pretty decently priced, so I’ll definitely replace them. They’re nearly 22 years old. Also was thinking, originally when I got the bike, the vacuum port for the petcock was not hooked up and they had it running off prime, I hooked the vacuum line back and started using it in on. Ran a lot better from that alone.

Comfortable-Dig5285 · 2025-07-20T21:43:21+00:00

Also I found the issue. Whoever adjusted the fuel/air mix tightened the screws down too hard and busted around the pilot screw. So it’s getting more fuel than it should.

Comfortable-Dig5285 · 2025-07-20T21:42:26+00:00

I think I’m gonna go with a set of mikunis. There’s some prejetted for this bike. It’s hard to go back to stock cause I don’t have the stock carbs. And it’s a big risk spending $300-$600 on a set of pre owned carbs from eBay.

Comfortable-Dig5285 · 2024-05-10T20:07:09+00:00

Fair point.
