sorry for the late reply..I was on vacation in Utah:). Thanks Superpacman13, I'll be ordering one.:cool:

I need a manual cam chain tensioner for my 2017 RC390 and I can't seem to find one anywhere. Anyone know where I can order one?

I've been running one one my RC390 and it works fine:rolleyes:

It's a bit of a hassle, but I would disconnect the PCV and hook the oem connectors back up just to see if it throws any codes...then you'd know if it was a PCV issue or not.

Yah it's the driven side. It didn't actually seize to the shaft but the bushing seized to the gear. I'm thinking some kind of assembly error or oil hole alignment issue. I'll have to dig in to it further. I didn't talk to my dealer about it because the 2 yr. warrunty expired in december. I've...

My 2017 rc390 seized the first gear bushing! Motor had 900 miles on it. Followed break in procedure. Plenty of oil in it. Not sure why it seized? Wondering if anyone else has had this issue and if there is a fix before I put it back together.

Had the same problem with my 2017. Turned out the water pump seals were put in backwards from the factory. They would leak at high rpms only.

I'm looking for a puller as well...just need the thread size and will get one from motion pro...but can't find the info anywhere!

I had a bearing go bad on my 2017 rc390. Seems to be on the output shaft. It squeals when in gear but sounds fine in neutral. I was wondering if anyone else has heard of this. The bike only has 1000 miles on it cause something is always broken on it.

A little water mixed in with the oil isn't going to hurt the bearings ...there's still an oil film on engine parts. I've had several motors loose water pump seals over the years and never had to rebuild the motor. Just flush it good ...I use WD40 to help disipate the water inside the motor...

thanks...I hate bringing my bike to a shop but I'll have to take it in to get it scanned. Hopefully they can pin point the problem and I can fix it myself.

Still no luck. I even replaced the battery with one off my DRZ400. I checked all the connections as well. What would cause the starter to continue to spin after letting off the button? I'm wondering if the short is in the starter switch.

Yah...I only saw the message for a couple seconds and my memory isn't that good lol. I replaced the battery last month...maybe it's a bad one. I'll look in to it...thanks for pointing me in the right direction!

My2017 rc390 ran fine when I parked it. Went to start it after a few weeks and it turned over...coughed...then died. After that it just turns over and the starter keeps running until I hit the kill switch??? I thought I fouled the plug but after replacing that and charging the battery (even...

Good point. The handle on the tool I made actually fits into the 6mm pin hole. I didn't want to risk deforming the upper by clamping too tight.

separating the upper from the lower is the hard part...but get it hot enough and it comes apart pretty easy with the right tools... I made my own.

The r6 ...hands down. With equal riders the r6 will smoke a rc on the track as well. The rc is a fun bike and is quick in the corners but way too slow on straights. (I have both bikes) That being said...A good rider on an rc can beat not so good riders on 600's and even 1000's .... street or track.

Thanks for the confirmation.
