Not to make this whole thing harder but.... whether you have the lash checked before you go or not, I would recommend getting it done as soon as possible if you are going to do it beforehand. The worst thing you could do in this case would be to have major work done just before leaving on a long distance trip. If you have it done at least three weeks before leaving, you might have time to have some type of problem with the work, such as an oil leak, fixed before the trip starts. Otherwise you will find any problems generated by the lash check itself while on the road and a long way from home and any technical support.
I try not to have any signficant work done on my bike immediately before taking it out of state, just in case there are problems caused by the work being done. Put another way, it would be nasty to change tires the day before a trip only to find out 500 miles from home there is a bead leak on one of the wheels.

OK I know that this is a can of worms. I am sort of behind the 8ball here. I am leaving for Alaska on the 24th. Will be gone 5 weeks and figuring on around 12K-15K miles. My 08 has just under 15K on the clock. I had intended to have the valve service done before I left, but time got away. I was fighting accessory installation and getting my autocomm to work.
So I ask the masses, do I try to squeeze in the check up, or do it when I get back?
