Took the TR4 out in an HPDE3 Session to test how she=E2=80=99s handling. I =
like how she handles but we have developed a lean condition.=C2=A0 Revs fal=

that did not really help. Neither did hotted plugs. Lyman checked valve adj=

Lyman figures we are running about 90 hp at the wheel. Hopefully putting it=
 on a dyno next month will help find the lean issue and maybe some more hp =
from this low compression engine.=C2=A0 This is the motor (and 5 speed Toyo=
ta) that was in the Baja Car which needs low compression to deal with low q=
uality fuel in Mexico.=C2=A0 This fall a rebuilt high compression engine al=
ong with a 4 speed Triumph box will be installed.
