Hi everyone,
As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.
When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.
Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.
Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.
Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.
Thanks for your patience and support!

1. Remove the tank. I have a 2008 with FI, so I don't drain the tank. I pull the plastic hoses and quickly plug the gas outlets with vacuum plugs.
2. You can remove the radiators or simply pull them back and hold them back with zip ties or bungie cord.
3. Pull off the various bits that get in the way, breather lines, etc. -- remove the small valve window covers.
4. Remove the spark plug -- put a long straw into the cylinder through the spark plug hole. Do NOT use a piece of wood or anything else brittle. It can break off in the cylinder and then you are looking at tearing the bike down. I have seen this happen twice on the Supermotojunkie forum.
5. You should have the bike on a rear stand, and in 6th gear.
6. Finding TDC -- looking at the straw, rotate the rear wheel until the intake and exhaust valves are in the up (closed) position, and the straw is at its highest point. Some people will do something to lock the rear wheel in place so that it does not accidentally rotate.
7. Place your Motion Pro feeler gage (0.002 inch) as shown in the photo. The 0.002 should be a little snug. If the 0.003 side can pass then the valves are too loose.
8. To adjust the valves, loosen the lock nut (in the photo, the lock nut is the one locking down the screw with the slot). Using a flat tipped screw driver, and leaving the 0.002 feeler gage in place, tighten the adjuster. You will not need to turn the adjuster very far. I don't know the pitch, but let's assume it is 1mm. So to get 0.001, you would rotate 9 degrees.
9. Holding the adjuster screw with the screwriver, tighten the lock nut. The tightening process, unfortunately, can change the clearance, so check the clearance again with the feeler gage. You may have to loosen and readjust, and iterate a few times to get it right.
