Days ago, I successfully installed the shift light. I tried the crank position wire in the past, but it never works. Finally, I connected the shift light to the black wire of ignition coil, and it works! It finally picked up the rpm signal. If you want to install the shift light, you can...

Yes, you're right. Changed the oil pressure sensor. Problem solved! Many thanks.

Hello Guys, Recently, I have a problem with the oil pressure. Last week, I rode my RC390 (2015) for 150 km, and went to the gas station to fill up the tank. After filling, I rode for 1~2 minutes, and the low oil pressure showed. (My bike's odo is 19000 km) I turned off, and re-started the...

Yes, that's true. I got a SPAL fan from e-bay, and took to dealer to change. Fan runs pretty well without any problem and it's quiet and efficient. It's far better than OEM fan. But my engine gasket was still broken. Dealer said the cause was the failed OEM fan which caused my bike...

Thanks a lot for your help! I will try to find out that wire. But the information about the wire of RC 390 is very little. It's very hard to know where the wires, connectors are. Fasteddy, do you have the photo of that connector or wire? If not, it's OK, thank you very much for telling...

Good day everyone. I'm trying to install the shift light pro on my RC390. I think I found where the crank position sensor connector is. But I'm not sure which wire is the right one which transmit the rpm. Is it the green wire or black/yellow wire? Could anyone let me know or take a photo to...

Actually, the shift rod wasn't knocked off. But the shift lever was. That reminds me I must confirm all the bolts are tightened up!! Mirror work is a Taiwanese brand. They produce rearset, brake lever, engine case cover, some CNC products. (But they has only rearset and brake lever for RC390)...

OK, thanks a lot for sharing. I just want to try add some contact patch at the front.I use Heidenau K80 tire, the 110/70 front tire has no extra contact patch, but the 150/60 rear tire still has some contact patch.Thus, I'd like to try the 120/70 front.

Has anyone tried 120/70 front tire on RC 390? Will it touch anything like fender or anything else? Hope someone can share the experience. Thanks!

No problem. Wow! Your dealer was so efficient! The vibration of RC 390 is so strong, I even lost my side stand fixing bolt! I waited for the bolt for 2 weeks to get a new one!!!

Yes, there should be a bolt with a black thick washer there. Yours is missing....

Yep, but my dealer just waited for the problem happening, he never checks the fan. And the fan problem for now never happened there. That makes me really unhappy.

Thanks a lot for your reply Vyzorr! I'll talk to my dealer and see how he will do for me. Anyway thank you very much for telling me. At least now I know the problem comes from the fan itself.:o But I still wonder how your dealer found the problem came from fan itself? How did they test it? My...

Hello Vyzorr, how did your dealer fix the fan problem? My RC 390 has the exact problem the same as yours. The fan sometimes runs, sometimes doesn't. I really want to know how to solve this problem. The same as you. Every time I went to the dealer, the fan works well. After leaving there, the...

OK, Fasteddy. Many thanks for your help. I'll check it! Thanks a lot.
