Ahhh...I knew I sent that to someone, but couldn't remember who.
Lots of 70° action in this video from Cross Training Enduro and Traction e-rag
One of my favorites and there are a couple Bergs in it so it's legal to share here.
Totally enjoyed that, thx!
I believe Barry owned a 70° a few years ago, so might have been his in vid.
My two bent Bergs
I tweaked the GB (idle circuit) up to 3 and it made an improvement so I bumped it up to 3/4 and the decel pop is almost completely gone and, so far, no more flameouts. I'm going to leave it alone for now and get the FMF 4.1 on this weekend and go from there. I've just been buzzing around the paved streets in the neighborhood so far and am definitely looking forward to getting this thing in the dirt!
This morning was a special time. I decided it was time to cut the strings on the ol 390 and let it grow up. I documented the ceremony for your enjoyment.
Okay, I have a dreaded oil question.
I changed the oil on my 390 earlier today and the sight glass was pretty much full to the top before changing. After draining the oil, and filter change, I filled it with the recommended 1.35 liters, started it up and let it run for a few minutes while I checked for leaks (all good there). Then, after sitting for awhile and cooling off, I checked the oil level and it is approx 2/3 of the way full on the sight glass. While that is technically in the range it needs to be, I have been toying with adding another .1-.15 liters to bring it near the top of the sight glass like it was before.
So, I guess my question is; how much oil are you putting in your bike after a drain and filter change and where is it on your sight glass? FWIW, I did try searching, but didn't really come up with anything.
I do 1.5 barely a air bubble visible on sight gauge
I do 1.35L, ends up around 2/3 of glass like you said. I just leave it there.
I go almost to the top.
You'll know when you have over filled as it will spit oil into the airfilter box.
Did you clean the screens?
I fill my 450 to 3/4 of the window with cool motor ( 1 min. running after oil change ). When hot the level is to near top of the window.
SOLD the tank. Guaranteed I run outta fuel first time out.
How much fuel does that hold? It works in conjunction with the stock tank, correct?
Yes, I did. I've had a few new bikes through the years and it's always a little interesting and/or scary doing that first screen clean out. I also drained every little drop out of the bike before the drain bolt and the lower screen went back in.
2 gallons + the stock tank
about last call for the 70° rally here. get your last ditch plans in place..
I gave the 390 a proper running in today. It's such a wonderful bike in the woods. 3.3hrs on the clock now. Time for the 3hr oil change and it's ready to rip! I ended up breaking the little rubber kick stand retainer. Does anyone actually use those?
I'm having one little issue with the EFI that happens right off throttle. If I'm in tight singletrack where the throttle is fluctuating between closed and maybe 1/4 open it will cough once in awhile and it even flamed out a few times. It seems to also do it after a long downhill section with very little throttle. When you reach the bottom and ease on the throttle it'll sometimes give a little cough or hiccup. I don't have any pop on decel. It's just that right off throttle area. I forgot my little JD reference card and the only circuit I had memorized was for the idle so I didn't mess with the tuner to try to get rid of it.
All told, it was a good day. No boil overs and no boiling gas (that I could tell). I have the fan set on 195° and it came on from time to time when the going was slow, but not excessively.
I bought my 390 used with unknown miles/hours and was experiencing the occasional flame-out under the exact same conditions you described. The idle seemed low, so I bumped it up a couple of clicks and the flame-outs disappeared. Not sure if the two were related, but...
