Can anybody confirm that the valve clearance for a 2010 TW200 is as follows

Intake 0.05-0.09 mm (0.002-0.004 inch)

Exhaust 0.11-0.15mm (0.004-0.006 inch)

Found these numbers for an older model, not sure if there were any changes for the 2010 model.



Since we are at that, anybody aware of ANY changes from older models to a 2010? I have the '87-'90 manual which I found on this site

The manual you have is from '87-'00. The place you found that manual on this site will also have a 'supplement' manual for 2001 and newer bikes.



Yes, there are changes...

Same clearances for the years.
Checked the "main manual" which I found on this site, it states '87-'90. Supplement manual made not reference to the valve clearance.

Am I correct to assume that your remark "same clearance for years" means that it is still the same?

Yep, same clearances for all years.



My mistake on the manual years (I see that on the manual now too), but get the supplement as that covers newer TW's CV carb, disc brake, and electrical.



I hate to speak in absolutes, but everything will be covered in the main manual (spec's, procedures, quantities, etc.) except for what has changed on the 2001+ TW's, and that will be covered in the supplement. In other words, if its not listed in the supplement then use the main manual for reference. If a discrepancy shows its face then best to ask.

Thanks for the tips. This site is really, really helpful.

On the left side panel of your bike (the opposite) side of your tool kit. Remove the left side panel and all the specs are on the sticker on the back side. At least on my 2009 they are.

But the sticker lies about the idle mixture adjustment.

When adjusting valves, which measurement should be used? eg Intake is 0.002 - 0.004. Should I set valves at 0.002, somewhere in between, or 0.004? Is there a benefit by setting to the lower number or is there a benefit setting to the higher number? Which number makes the valves tighter, the lower number or the higher number? I ask these questions because I don't know the answers and I haven't been able to find the answers in any search that I've done.



Thank you for your patience and answers.

I don't think it makes any difference.. Maybe at WOT with the engine hooked up to a dynamometer might show a minute difference but hardly one you could feel.



I have two feeler blades out when I adjust valves. For example when doing the intake the .002 and the .004. If the .002 is loose and the .004 is tight I am done. I don't try to hit an exact number.

Valves tighten with wear.



Be honest with yourself, and if you're not gunna be very anal about valve adjustments keep them on the high side.



Tony's "go, no-go" method works just as well at the exact settings as it does for ballpark settings. If an .004 will go and an .005" won't, you're golden.

That makes good sense. Thank you for your prompt reply.

Great. Thank you for your reply also.

I adjust mine to the lowest end of the specs because I'm a freak about tending to maintenance and tighter clearance makes a quieter engine. Lizrdbrth said it best though, most folks who aren't obsessed with minutia should probably go a little looser and forget about them for longer durations.
