TSB = technical service bulletin

Hey Eric! Glad to see you here and have fellow brazilian rider around. Hope you enjoy the forum as well as I do.

Do you mean that the 939 clutch assembly fits the 821? If that's the case let us know how it went.

A bike repair shop with Texa's diag tool can read the current sensor values that the ECU is reading.

Bad sensors do not always throw a code. If the stalling happens during hot weather and hot engine it should be something sensor related. Do the air and coolant temperature sensors read the right temperature? The ECU sends less fuel on hot days to compensate for the decrease in air density. Did...

Did you check the sidestand switch? It can cut off the engine randomly if it has a problem. You can bypass it and test it.

I fixed the dash lines in the odometer a while back at approx 20.000km, now at 36.000km my odometer turned to dashes again... here the dealer charges an hour labor just ti fix it. I didn't find any DIY way to fix this issue.

Well, I'm about to do this job and all bolts are seized to the point it won't move before damaging the allen hole. Do you guys have any suggestions to loosen those bolts? I was thinking of using a manual impact tool.

Second update, Alessandro from UpMap has uploaded a second version of the H821_13_D133_FD_box and H821_13_D133_FR_box maps. I have tested the H821_13_D133_FD_box and the lambda sensor removal problem has been fixed. The bike now runs without them and is smoother than before. They did take a...

Hi guys, Just a follow-up. No answer from Termignoni UpMap. I can say that my experience with UpMap support has been terrible. It's been at least a month an no reply. So, I've bough a map that was supposed to disable the lambda sensors, but it's not. I'll keep them plugged and look for another...

I could reset oil and desmo service with the Melcodiag connected to the 4 pin port. That’s all. Until now Melcodiag doesn’t support resetting the TPS for the 7sm ECU. Using the right FTDI chipset is a must for this procedure. I use the one from Lonelec. Download the latest version of Melcodiag...

The picture comes from my UpMap account page. The map upload process finished with success. I see this in the UpMap page:

So purchased and uploaded the map "H821 13 D133FD BOX", same version and same ECU as Stefan (2014 HYM SP). Disconnected the lambda sensors. Started the bike and once it warmed up it started farting fireballs and shaking. Connected the lambda sensors back and it came back to normal. So, I'm...

Thanks Stefan. I've sent a message to UpMap about my issue. I'll post their reply so anyone who come across this post will be informed.

Hi there Stefan, I have also the T800 Upmap with the "H821 13 D133FR BOX" map. I've been happy with it until a couple of weeks ago when my bike started acting up. The idle was erratic, low power in lower RPM, and I could rear pops from the exhaust while driving and during idle. Well, the rear O2...

These are the first gen gecko racing rearsets.

There’s one in your tool bag under your seat. You can buy a 14mm plug socket (they’re longer with a rubber insert that grabs the plug when it’s loose) + socket extension. I’ve never set gap on new plugs but AFAIK the gap is already set (compared owners manual and ngk docs)

An spinning push rod can cause slave cylinder failure. Does yours have the anti-spin pin on the slave cylinder end?

Hi Saken, Don’t need to pay for personal use. If I recall correctly there’s a button in the main screen that’s sends you to a page to request the license file. It will forward your VIN to JP and send you the license file to your email.

Yes. This is the same harness I have for the Hypermotard. You're right. You can see/clean error codes, but not the service warnings. The Melcodiag developer didn't figured how to do it on iaw7sm Marelli ECU. Many has had issues with O2 sensors burning. I got rid of them with the T800 map (full...
