valve shim question
Gentlemen,
I need to know if I figured the difference on my valve shims
correctly. I pulled out the following shims with the existing
clearances: left intake - 230 at .004 clearance, right intake - 230
at .003, left exhaust - 235 at .005 and right exhaust - 235 at .005
From what I understand (I'm smart, I can handle things. It's not
like what other people say! as said by curly of the three stooges) I
need to leave left intake alone, pop in a 225 for the right intake
and my 230's for the left and right exhausts in order to meet the
high side of .004-.008 for the intake and .006-.010 for the exhaust.
Is this right? And these valves would be on the tight side, right?
Would my .003 reading for the right intake be small enough not to
replace with the next smaller shim (225)? And please don't tell me
to wait for the Julian Tech Session next Saturday 'cause I already
have it all opened........

You're better off with more clearance (more miles between valve
checks).
Replacing the 235's in the exhaust side with 230's will give you a
clearance of .007. I'd go with the 225 in there to up it to .009.
On the intake side, 220's on both sides will give you plenty of room.
Those clearances seem pretty tight, how old is your bike? Also, I
seem to remember 250's, 255's, etc. being more common in the stock
configuration.
I came up with those values using Shimcalc.eve, but I'd feel more
comfortable giving pointers after seeing it with my own eyes.
If you do make it to Julian, it only takes 45 minutes or less to rip
the bike apart and eyeball the clearances...
Cheers

Hit the software link on the left and d/l ShimCalc.
I think without paying for it, it will display 3 of 4.

I'd put 220s into the intake side and 225s into the exhaust side. That should leave you at 008 and 007, intake and 009 and 009 exhaust. Warning, no shim calc here. Just used my addled brain.

valve shim question
I checked my shims and the right intake was right at the narrow end of
the spec at .102 mm (.004'') with a 265 shim. I wanted to bring the
clearance to the wide end of the spec with a 255 but the local dealer
didn't have one and I didn't feel like waiting so I'm going to button it
back up.
My question is: given a bike with 2100 miles on it and 'normal' riding
conditions (around town, some highway, some off road), how long should I
wait to recheck the clearance again?
Also, I bought this bike used and don't know if the clearance was ever
checked before. The left and right intake shims are 260 and 265,
respectively. Are the engines always set up from the factory with the
same shims on both sides, in which case different shims would indicate
the bike has been serviced already, or is it normal for them to come
from the factory with different shims?
Thanks, Mike

Thanks to all who replied. I ordered some shims from Arrowhead and buttoned it up for now, since it is still within spec. I'll go back inside and put in the new shims in 1K miles. --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

valve shim question
Today I decided to check my valves on my A18 with 1400km I had no
problems getting to them except a tight fit on the valve cover. the
exahst was in the upper limits around .007 for both, but the intake was
tight 'round .004-.005.
Question one. Is going from .005 to .010 w/shim O.k? Or is too much?
Question two. Is there any way to know If there is a starting range on
shims from the factory? or am I going to have to stop halfway through
to go buy shims
Last question. Is there anything that I should do while I'm without
tank and bodywork?
Thankyou so much for being so intresting, informative and enthusiastic
towards such a cool motorcycle. without this group I think I would
enjoy owning mine alittle less.
thanks
A.

Nice time to check the spark plug since you can really see in there and make sure nothing falls in when you take the plug out. -- Doug Herr doug@...> Last question. Is there anything that I should do while I'm without > tank and bodywork?

Going to the next smaller shim opens up the clearance about .002". While the tank is off it just takes a couple of seconds to check/replace the plug.
