I wanted to see if anyone has a clue what could be worng with my bike.
Here's the story...
1992, Stage 7 (175 mains, needles on second notch), Kerker 2.5"
When I dyno my bike it makes great power up to about 100 mph, sorry didn't
hook the tach lead up for RPM. That's where things go to hell, it completly
falls on it's face. I have tried and dynoed about 15 different needle and
jet combinations with the same results. The bike always does the same thing
at about 100mph it flat lines. Stan ran his bike the same time with the
identical setup and our curves were identical until the time mine stopped
pulling. I tend to think this eliminates compression problems but I am going
to do a comp check and leakdown in a couple days. I am thinking something in
the ignition. Possibly a weak coil is killing one cylinder. How would you
load test a coil? Can anyone think of anything else that could cause this.
The bike has tons of midrange and runs great it just falls on it's face on
top. Any ideas would be great. I have battled this monster for a year now.
Thanks
Scott Thompson
