what do you make of this?

[UltraNutZ]

2011 Road Glide 103" - returning to "semi" stock to sell
cc-d stock heads prior to installing - 85.7 front and 85.2 rear (cleaned the chambers very well.  all nice and shiny)
stock pistons
.030 Cometic HG
SE-204 cam
75' above sea level
System relay pulled and throttle blade open


cold measurement
226.0 front
218.0 rear


hot measurement
217.5 front
208.3 rear


This is a far cry over what BB site states

maybe try a different gauge.
...that seems awfully high to me.

Nothing.

 I'd thought it should of been right around 200 ccp's @ 75' elevation.

me too.

I have a 103 / SE204 build with no headwork and as close as I can calculate BB says mine should crank 158, but mine tested at 170 cold

One thing to remember is the motor does not see altitude it sees pressure. The altitude correction is for standard pressure at sea level. If you have a barometric high pressure the day you test, things will be different then if you are under a low pressure system.

[UltraNutZ]

29.93 here currently.

What was your motor temp for the hot test?
What did you set your ring gap at?

[UltraNutZ]

pistons/rings are stock

temp was 226°

Do a cylinder leak down test and if they are within 5 to 10% its good to go. I wouldn't be to worried about it I see 20 lbs difference between cylinders on v8s all the time.

[UltraNutZ]

yes sir, did a leak down test.. all is good there..

was just more surprised to see such high CCP numbers cold and hot on both cylinders, not so much the difference between the 2 cylinders.

My bike cranked 210/210 with 204's and the .030 Cometic, I verified it on 2 gauges.

Edit: I'm at 400ft

Nice!  Didn't even think of that..   

[kd]

They must have been pumped up for the hot test?   

[UltraNutZ]

i kinda assumed BVHOG was referring to the cold measurements.

[kd]

Yeah, I should have reread the post with the #'s.

I'll recheck mine warm and see how much it changes
