I did the valve lash inspection/adjustment on my girlfriend's 2012 V-Star 950 this afternoon.
It, the Bolt family and the SCR950 all share the same basic engine with just cosmetic differences..
Tool gathering, actual work with a throttle body synchronization afterward AND washing the bike took 3.5 hours.
It's nice having all the right tools on hand!
The bad first.
I had to take a ton of stuff off the bike just to get at the valve inspection caps and ruined a rubber wel-nut in the process. Not an issue as I keep a small supply on hand. The SCR950 doesn't have one to ruin. Her bike sips gas and despite the fact we rode 100+ miles yesterday, it still had a bunch of fuel in the tank. It's a lot bigger than the SCR's and cumbersome.
The good:
The inspection caps are held on with five 5mm hex head bolts each and have o-ring seals.
Be careful not to break one and they are reusable. The rear exhaust seal stuck 1/2 on the head, 1/2 on the inspection cap.
The inspection caps weren't terribly hard get at and are nice and big, allowing lots of room to work around the valves.
All four exhaust valves were in spec, favoring loose from the middle of the specified range. Happy! The intakes on the front cylinder were at the limit toward tight and the rears were a hair past loose.
I set all four in the middle at 0.10mm and buttoned things up.
When I went to check the throttle body synchronization, they were a gnat's eyelash from perfect. I tweaked the adjustment screw a tiny bit and the electronic balancer said it was dead-on.
The best part:
It was free.
I already had all the tools and with screw & locknut adjusters, no expensive shims required.
Tools: Needle nosed pliers, 4 & 5mm hex wrenches.
12mm box end wrench. 10mm, 12mm & 19mm sockets.
Small standard screwdriver. Brake cleaner. WD-40, silicone protectant (Armor -all, etc...) paper towels, feeler gauge set,
Familiarity with a f.i. fuel line quick connector.
Rags and a carb balancer if you want to do the synchronization when done.
Optional for me only because we just changed them:
2 NGK CPR7EA-9 spark plugs.
Bonus photo: My pit crew - Sherlock the cat.
