Title: Tight valves question, need answer fast!
Post by: Octarine on April 06, 2013, 10:42:25 PM
Ok, 85 K100 with 31k showing but most likely more.

Went to Motoworks this morning to pick up maintenance supplies. Whenever I buy a new bike I assume nothing has been done and the molasses in lieu of brake fluid is proving me right.

Checked valves and found intakes are at (1-4 left to right)
1).203mm  2) .127!! 3) .178 4) .178 but prob a hair tighter

Exhausts:
1) .203  2) .203  3) .229  4) .229

Those are mm.

So obviously I got some shimming to do in my future!

I am ordering the tool from Ken, he is close to me unless someone in Chicago can lend me one.

Here's the $64,000 question: can I ride her with those clearances?  I work retail and after tomorrow im basically working two weeks straight with no chance to get to Motoworks:(.

I was planning on heading to the Full Moon in the morning after I flush the brakes.

Thanks!

I don't think you're going to hurt anything riding it for a couple weeks like that.  I've seen tighter exhaust valves that once reshimmed held their clearance for another 40,000 miles.

Cool. My experience with air cooled bikes makes me cautious.  I gather the water cooled K has more stable operating temperatures than the old GS1100!

Good to know. In my non bmw experience, driving it till it wont move ends up with me parting out a bike on craigslist. Not my idea of a good time!
