If you run the snot out of it in high R's you'll be doing it a few times
More fun than soldering your lip's together!!!

Thanks for the heads up. Something like that could take the smile off a persons face real fast.

Good Job!

Way to go on the valve clearance adjustment Austin. I know it felt good after I did mine. I recently had to change out six buckets (all intake). All were in spec after the change. I have yet to start mine back up due to still working on getting the new throttle cables installed. I will be back to work on it tomorrow though.

Ride safe,

James

ajs An update on my valve check and adjustment project. Rec'd 7 new followers from dealer, installed same, reinstalled cams, and all related parts, everything lined up according to info from this site, and Clymer, rechecked for clearances as follows; All intakes are now at .007 and all exhausts at .010. These checks were made 3 separate times and all 3 times the readings were the same.

I am very happy with the results. They are certainly a lot better than the clearances I got initially. I have completed the reassembly of the top end of the engine, and except for final test, (but WILL IT START) I am completely satisfied with the way it turned out. Not bad for a first timer on a K12 engine. Many thanks from all on this site who helped me out in one way or another.

P.S. I haven't started the engine yet because I am in the middle of an oil change and other routine maintenance checks and repairs, but that will come in time.

Thanks again
Austin S.

Valve adjustments are not a warranty item, but a standard maintenance procedure. Warranty does not cover standard maintenance adjustments.

Warranty repairs for an adjustment thats part of a service interval? Good luck...more than likely a bill if you want the valves adjusted.

ajs Rechecked the readings this morning with loose gages. For the most part yesterdays readings were verified. Three additional exhaust valves showed up as needing adjustment. Two were down from readings of .010 to .009 and one was down from .011 to .009. I rechecked them a number of times to be absolutely sure and am satisfied with todays readings.

ajs On the question of feeler guages. I used two sets of guages none of which were loose. One was the typical 'jack knife' type. The other was a 12" long 'jack knife' type. I checked first with the shorter ones and rechecked my findings with the longer 12" ones. They, for the most part confirmed my findings with the short ones. In a couple of cases they were a better fit between the lobes and the buckets. I agree this is a critical measurement and therefore I will recheck in the am with loose guages just to be absolutely sure. Thanks for the heads-up on this one.

Austin, I would echo John's statement and to make SURE you are checking the clearances properly. I know I checked mine at least 4-5 times before I felt comfortable I was checking them properly and getting the same reading. I have not had a whole lot of experience with using feeler gauges and after removing the feeler gauges from the tool (using a loose gauge), my valve clearance numbers changed (for the better).

I ended up changing 6 intake buckets, and no exhaust.

Another bit of advice would be to make certain that if/when you do change buckets, to make sure you properly relieve the tension in the chain to allow easy placement of the sprockets onto the end of the cams. This was a big learning step for me in this process.

Best of luck to you.

Valve clearance checks

Have just checked the valve clearances on my '05 LT. They are as follows;

Cyl. #1.. In (a) .005 In (b) .006 Exh (a) .009 Exh (b) .009

Cyl. #2.. In (a) .007 In (b) .006 Exh (a) .010 Exh (b) .010

Cyl. #3.. In (a) .007 In (b) .007 Exh (a) .010 Exh (b) .010

Cyl. #4.. In (a) .005 In (b) .004 Exh (a) .011 Exh (b) .011

The bike has 23,750 miles on it.

I have not disassembled anything yet to check shim thickness but at this point intake (a) and exhaust (a) and (b) on cylinder #1 are in need of replacement along with intake (a) and (b) on cylinder #4

Any comments, helpful hints, or other insight on this would be appreciated from any and all you experienced in such matters.

Regards,
Austin S
