Well for comparison, today I did a compression check on a GT6 (same motor,
500cc less), and the figures were 160, 161, 162, 163, 160, and 163. Very
nice for a used motor! I believe when I did a compression check on my TR6
oh, two years ago, the figures were all around 145-150.
Try adjusting the valves, see if that helps some. If no help, find a shop
who can do a leak down test and figure out where you are losing pressure
from.
