Re: 70 degree valve check/adjustment

Ok, I finally worked up the courage to check my valves on my 2011 FE570S. I have had problems with this bike and it has never been reliable. The dealer changed the camshaft under warranty but it has never started properly cold. It also has the nasty habit of not wanting to start after sitting for 10-15 minutes like when stopping to rest on trail.

Here are the reading I got. WARNING: MATURE AUDIENCES ONLY!

Intake: 0.076/.051
Exhaust: .0102/.0102

How could my valves be that far out of spec? Bike has about 50 hours on it.

Fine sand in airfilter?

Do you often hose your bike under high pressure but afterwards do not swap out the wet airfilter?

I know I am a bit anal, but I will never start my bike after washing with a wet airfilter. I did this also not with my RMZ nor DRZ and I never had valves out of spec.

Re: 70 degree valve check/adjustment

I have ridden in some dusty conditions but seemed to have a good seal on the air filter and serviced it regularly. Whenever I wash the bike, I put the blue air filter cover to prevent water getting into the air filter and don't typically start it wet but I couldn't swear that I haven't at one time or another.

So I guess I just replace the shims with some smaller shims to get it in spec and see how she goes?

Checked my valves after 90h (3700km): still in the middle of the specs. Managed to do it without removing the tank only loosening the radiators.

Hi all,

Valve check @ 80 hours on FE390 @ 20 degree temp.

TDC lined up with dots perfectly together

(one question, if I go slightly past TDC, I can 'knock' the rear wheel backwards to line up the dots - is this valid?)

My issue is my feeler gauges only go as small as .008 and I can not get this into either of the 4 valves.

The bike runs great, only apart as I was getting ready to wrap the pipe and it's well due for the check.

any thoughts?

And if this is correct, what shims would I need to get this within spec?

thx!

so more reading has me now believing that i'm simply using incorrect gauges

The smallest I have is .008 and goes up from there

My mis-understanding is/was thinking that 0.12 = .012 for my feelers... which is WRONG!

Temperature: 20 C degrees (68 F degrees)
Exhaust valve clearance: 0.12 -- 0.17 mm (0.0047 -- 0.0067 in.)
Intake valve clearance: 0.10 -- 0.15 mm (0.0039 -- 0.0059 in.)


Based on this proper way of thinking, it's GOOD that my 0.008 didn't not fit, as that would mean the gap is .20 and far to large!

So now i'm off to get a proper set of feelers and check this correctly!

(damn i feel dumb!)

I Ride: 2011 FE390
Bike: 2011 FE390
KM: 3006
Hours: 83.6
Riding Notes: a mixture of trails and street riding with 17" supermoto setup

Intake R: 0.10mm - slightly hard @ .10 - 0.08 is super easy, 0.13 would not fit
Intake L: 0.10mm - slightly easy, could be 0.11? 0.13 would not fit
Exhaust R: 0.15mm - slides in with light pressure - 0.18mm would not fit
Exhaust L: 0.13mm - slides in with light pressure - 0.15 would not fit

These look great to me with the possible exception of the right intake. It's slightly tight but i'll leave it for now and be sure to see how it changes on the next check.

I still have to put everything back together, but overall this wasn't that difficult and i'm glad I managed vs. bringing it somewhere to have it done!

Huge thanks to Davo for the write up and pictures (and to everyone that reports back, more info the better!)

Also, as the pictures currently are not showing up, i just wanna repost the great pdf link that DeeG posted and is hosting on his dropbox: https://dl.dropboxusercontent.com/u/...ve%20Check.pdf

If by some chance this link ever dies, I have a copy saved and if someone wants it, just pm me and I can send it.


(I'll leave my previous comments just in case someone is as dumb as I and happens to run into a similar issue, hehe)
Thanks from bushmechanic, tourist and zimi
