New member, long time lurker here. I finally bought a computer and moved into the 20th century (although I do realize it's now the 21st).
Anyway... I own a 2000 400EX in which I have just installed a new Weisco 11:1 piston (86mm = .040 over, or 406 cc), and a Hotcams Stage 2 cam, in addition to my Pro Circuit T-4 and K&N.
As a fairly adept but somewhat fumblefingered (is that a word?)mechanic, but by all means no expert (first bike was a used 1984 200X, when I was 13 in 1986). Times have changed and I certainly have a lot more money invested in this, but thinking this would be no problem, I shot from the hip without a manual. Things have gone pretty good so far, but I do have a couple questions.
1st - cam chain tensioner..... when reinstalling, I loosened the middle bolt, set the adjustor at its most loose setting, tightened the top and bottom bolts, and then let the adjustor out until I felt it hit the timing chain. Is this the correct procedure?
2nd - At TDC, lobes down, the cam sprocket shows one mark perpendicular to the cases, and two parallel. Am I in time?
3rd - Hotcams says to use plenty of lube. How much is too much (I creamed it on pretty good.... If I were having intercourse it would be a little sloppy :-) ?
Finally, I am starting it up on Valvoline 20W50 raceing (switch to my regular Mobil 1 15W50 after break in), VP C12 race gas, valves set at .005 Intake and .006 exhaust (stock is .004I and .005E, Hotcams says just a little looser than stock), is this in the ballpark?
Any INFORMED replies would be appreciated (although speculation is also welcome... as long as you don't feel guilty about keeping me awake when I have to be at work at 0700).
Thanks for your help,
cerberus
