TDC adjustment

[bikerphil]

Take the shim out, look at the number printed on the bottom, put one in with a number that is less, take your measurement and determine the correct number needed.

Valves

When replacing the shims and valve adjustment, how do I do it if the shims are tight. All the threads I find mention I measure the space between but my thinnest shim won't even go in.

As the valve seats wear, the valves go UP in the cylinder head.
This closes the lash gap. That is why the lash gets smaller. We are programed to think just the opposite.

A special tool and a selection of shims is needed to perform the valve adjustments. When performing this repair, always turn the engine by hand. Do NOT use the starter to turn engine while adjusting valves.

Here is a link to the procedure:

Some enthusiasts say to remove the cams to adjust valves - a totally incorrect procedure.

Can I still drive my xs if the valves are tight? I drive 14 miles to and from work and won't be able to work on the valves into Sunday.

That's a good question...If I remember correctly...I would say you shouldn't drive it...But I never own a inline 4 engine before...Doesn't the engine run hotter if they are tight...I have always been told a little valve chatter noise is far better than them being tight...Your Call

Are you measuring them correctly? 180º opposite the highest point on the lobe where it contacts the shim?

[coolbikr4684]

I'm pretty sure I measured correctly. Well than I will keep it parked until Sunday

If they are all that tight you could burn a valve.

When measuring for the shims all my valves are tight so ho do I measure for the correct size? I'm guessing I have to remove the shim and than measure with no shim installed and do the math from there. I just want to make sure I'm measuring correctly before I dive into it and start it.

Back to the fuel filters... If your in tank filter towers are in good condition, the paper filters do nothing. Bikes have been run decades and decades and decades with the filter towers in the tank. If stuff is getting through the tank filters, assuming they are in good condition, you have bigger problems!

I run some little lawn mower filters anyway. Peace of mind.

So my shims weren't as tight as I originally thought there was clearance but minimally.
E1 .008 Y285
E2 .008 Y285
E3 .008 Y285
E4 .008 Y280

I1 .005 Y280
I2 .006 Y275
I3 .006 Y275
I4 .005 Y275

If I follow the chart that I have on some of the threads I would need to change to
1 E275
2 E275
3 E275
4 E270

1 I265
2 I265
3 I265
4 I270

Just want to confirm before I go and buy/exchange some

So I messed up the numbers on the previous post. I mixed up mm and inches, good thing I always measure twice and cut once.

So my shims weren't as tight as I originally thought there was clearance but minimally. Measurements were done in inches.
