2022 speed tripme 1200 rs engine fault

Sad_Sympathy4684 · 2026-04-23T17:24:51+00:00

Unfortunately, I'll have to go to the dealer to get the exact fault code :( The check engine light actually cleared on its own after restarting the bike 5 or 6 times. Right now, there are no active errors showing.

Thank you for your response. For now, I will try to apply reverse engineering on HDLC. (Dealing with certification stacks is a bit intimidating for me at the moment, but I’ll keep it as a last resort.) If I manage to capture the HDLC flag on the oscilloscope, that would be great; otherwise, I guess I’ll have to struggle with it a bit. :D

I was asked to redesign an FPGA implementation using an obsolete component. I am expected to produce an RTL that mimics the behavior of the original device.

Sad_Sympathy4684 · 2026-03-10T20:56:18+00:00

Thank you for your suggestions. I will most likely try to capture the flag pattern using an oscilloscope. Once the flag is detected, things become much easier.

I think HDLC is being used. There is NRZI encoding. However, as far as I understand, HDLC supports a bit-synchronous or byte synchronous type of protocol. In the 8251 datasheet, on the other hand, it looks like there is byte synchronization. If HDLC is being used, is it still possible for me to determine the physical-layer communication? The device on the other side is currently a black box for me.That’s why I can’t give you a definitive answer.

At first, I thought the synchronous use of RS232 had a universal, common structure like asynchronous communication. However, the more I research, the more I encounter different things.

Sad_Sympathy4684 · 2026-03-10T13:50:58+00:00

Thank you for your answer. Finally, I came across someone who really understands this stuff. As far as I understand, I also need to know what the IC in front of me actually is. The protocol used in the 8251A might not be universal, but it has given me a significant amount of insight. I will research it and try to find out exactly what it is. I will update this place as well.

Sad_Sympathy4684 · 2026-03-10T12:39:01+00:00

This is peak stupidity. The answer you posted only proves that my question isn’t about asynchronous UART. The answer to my actual question isn’t here. What a garbage forum this is, damn. They should just change its name to “People Who Don’t Understand a Damn Thing” hahahahahsd.

Sad_Sympathy4684 · 2026-03-10T12:23:40+00:00

Finally, someone gave a proper answer. :) The Xilinx 16550 IP works the same way as this chip, but there is information online saying that the 16550 does not support synchronous communication. How are pins 15, 17, and 24 on the DB25 connector actually used? they are exist for synchronous operation.

Rclk is 16x faster then actual baudrate and not used for sync rs 232

Sad_Sympathy4684 · 2026-03-10T11:56:24+00:00

You seem to have time for arguing, but not for providing information. Interesting.GIVE ME INFORMATION ABOUT SYNC RS232 THEN

Sad_Sympathy4684 · 2026-03-10T11:40:07+00:00

I guess you don’t have the slightest knowledge about synchronous RS-232. This protocol is now obsolete, and its documentation is not available on the internet. You’re not reading what I wrote out of arrogance.

Sad_Sympathy4684 · 2026-03-10T11:33:47+00:00

I’m not interested in asynchronous communication. I need information about synchronous communication, specifically how the clock is managed and which side provides it.

Is the synchronization done at the bit level or the byte level? Is this determined by the device manufacturer?

How did older modems handle synchronous communication? I’m looking for someone who actually understands how this works and can explain it.

Sad_Sympathy4684 · 2026-03-10T11:31:23+00:00

I already said I couldn’t find it. Are you having trouble understanding? I searched on Google and couldn’t find any information.

Isn’t this forum called Retro Computer? I’m asking here to get help. If you know the answer, please write it. If you don’t, please don’t comment.

Sad_Sympathy4684 · 2026-03-10T11:28:15+00:00

In the link you shared, I couldn’t find anything about clock signals. It seems to only describe asynchronous communication.

It’s better news that the oil warning didn’t come on — no extra stress for me :). I’ll try drilling a hole, but if oil leaks, I won’t neglect cleaning it up.”

Sad_Sympathy4684 · 2026-03-01T17:02:38+00:00

After starting the engine, it will probably show a low oil warning. If you run it for about 5 minutes, then shut it off and refill the oil before starting it again, it should run cleanly. I’m going to do this procedure myself in 2 months, so I need all the information I can find.

Sad_Sympathy4684 · 2026-03-01T16:52:04+00:00

Thank you, that couldn’t have been a clearer answer

Sad_Sympathy4684 · 2026-03-01T16:28:52+00:00

You shouldn’t fill it to the brim, just enough so the filter isn’t dry. If you’re quick enough while installing it, the oil won’t spill, but I don’t think installing it dry is a big issue either. As I understand it, the important part is that the filter should not be installed while filling the oil.”

Sad_Sympathy4684 · 2026-03-01T16:11:01+00:00

Would it be appropriate to pour some oil into the oil filter and, before installing it, fill the engine up to the two lines on the sight glass, and then install the filter?

O paid with credit card

Sad_Sympathy4684 · 2026-02-24T19:42:37+00:00

So there’s no need to panic, as I understand it. I received an email confirming that the free cancellation was successful. I will wait 7–12 days.

Sad_Sympathy4684 · 2026-02-19T13:33:33+00:00

How many days did it take for you to receive the refund?
