Re: 70 degree valve check/adjustment

A couple of TDC questions for valve clearance measurement:

(i) Re using the crankshaft locking bolt when you find TDC, is it necessary to buy special part #113080802, or is it sufficient to just remove the existing bolt and thick copper washer (at 8 o'clock to the oil filler cap) and replace the bolt only without the thick copper washer (so its longer)?

(ii) when crank marks are aligned re finding TDC on the COMPRESSION stroke, (so you arn't 180 degrees out) I assume that is guaranteed by putting a drinking straw down the spark plug hole and when it stops rising up, thats TDC of the compression stroke thats used to measure valve clearances? Or is it just guaranteed when all valves are loose?

Thanx in advance

(i) Yup. You only need to remove the thick, copper washer ... and re-insert the bolt. *GENTLY* hand tighten and your crank will be locked in place.

(ii) Not sure what bike we're talking about here. But if you're and '08 and on KTM 450/530 ... or an '09 or later Husaberg ... simply lining up the dots on the cam gear and the cam tower is sufficient. You don't need to worry about being 180 degrees out like on the older RFS motors.

Cheers! E-Ticket

Re: 70 degree valve check/adjustment

Hi Fizz,
I agree with E-Ticket, line the dot up on the Camshaft with the Drill mark on the Head and the piston will always be at TDC. I think you are getting confused with lining up Crankshaft marks on engines. It is possible to get TDC on engines with Crankshaft marks but your Camshaft can be at 2 different places when lining up Crankshaft marks because the Camshaft spins twice as slow as the Crankshaft. So when a Crankshaft is at TDC it could be the top of the Exhaust Stroke for the Camshaft or top of the Compression Stroke for the Camshaft. When the Drill mark and the Camshaft mark line up on the Husaberg it is at TDC Crankshaft wise and top of the Compression Stroke Camshaft wise.


E-Ticket, DOH! I just ordered that Crankshaft locking bolt yesterday for next time I work on the engine and by the sounds of it I donít need it.
Anyway, I will post up what it actually is when I get it.

Re: 70 degree valve check/adjustment

With all the pics on this thread I decided to do my valve check today. I am just heating up my garage to 20 degrees celcius and will take a reading and report findings.

In the process however I noticed (FE390 2010 bike at 36hrs):
- my spark plug was VERY black (hasnt been changed before); and,

- I installed the dirt tricks cam chain tensioner 2 days ago (to see if it solved ticking engine noises - which it didnt - so thats why I am doing a valve check) and looking down the head at it internally, the dirt tricks tensioner is already extended somewhat and the cam chain looks VERY tight (I did install the tensioner with the bike lying down so it doesnt extend when installing via gravity).

Is this normal?

...
1 hr later now and garage at 20 degrees celcius; readings measured several times and are:

Inlet Valve In Spec Range 0.10-0.15
==============================
Inlet Valve (top of cylinder): Left 0.10 =====> borderline OK
Inlet Valve (top of cylinder): Right 0.10 =====> borderline OK

Exhaust Valve In Spec Range 0.12-0.17
=================================
Exhaust Valve (bottom of cylinder): Left 0.15=====>OK
Exhaust Valve (bottom of cylinder): Right 0.13=====>OK

The additional questions I also have now are:

- So now the bike is all undone, I assume its best for me to order thinner Inlet Valve shims so I am in the middle of the range and not on the lower limit; does this sound logical, or is it a case now of its not going to change now for many hrs so dont bother changing to thinner shims?

- my bike (even with Dirt Tricks Cam Tensioner) ticks alot on rhs of the engine, even when warm, so if the valves are proven in spec - is this ticking 'normal'?

- my inlet valves at .10 ; does this confirm the theory that valves tighten over time?

Thanx in advance.


Regards

Re: 70 degree valve check/adjustment

So my intake valve clearance is in spec at .10 and .10 on the 20110 FE390; I asked earlier if I should bother changing shims, but I've just realised that if they only have shims in .05 increments then there is no point I guess.

My bike valves are in spec and I replaced CCT with Dirt Tricks one, but the bike still ticks like a bomb - can anyone confirm that this ticking is 'normal'' ? I only use high grade 98 RON fuels (BP Ultimate in Australia).

Thanx

Re: 70 degree valve check/adjustment

My 7 hour 390 ticks, and the valves are in spec. Pretty sure it did before I adjusted the valves!

Harley does shims in smaller increments if you want to get it closer to the spec mid-range. However, then you'll have Harley parts in your bike. You might find the urge to wear chaps, your bike will only get out on sunny days, all rides will end up at a dumpy bar, any ride longer than 100km will be considered long, and you'll start referring to your riding buddies as `bros'.

Re: 70 degree valve check/adjustment

I am off to the HD shop before work to buy my shims - I will be dressed in business attire so may be denied entry

I assume I just smother the new shims in fresh oil and press them in to place with a feeler guage?? Can someone please confirm. Easy/hard to get in?

Thanx in advance

Hey Fizz, that is all I did, just oil and sit them in there.
I then put everything back together in the head, wound the engine over 3 or 4 times and then checked the valves. I could have done with one of those 2.875 Harley Shims.

Re: 70 degree valve check/adjustment

I checked my valve clearances last week. I currently have 140 hours on my '10 FE450. They were all in spec.!!!!!
