"PRODUCING WHAT OTHERS JUST PROMISE"
| TECH UPDATES |
New for Predator 1100 & 1108 Triple - Gas Pressurized Piston w/ Rings!
We have found 3-6HP Gains by adding a series of .040 Holes around the circumference
of the piston dome to improve ring seal on these single ring pistons. If your pistons are in
good condition we can modify them accordingly for $20ea.
All New 1100 & 1108 Pistons now come with this update.
Predator 1035 - We have found that some of the 800 + 900 ignitions have less timing
than others and may require a larger offset key for best performance. If your 1035 will not
pull 76 gram arms to at least 7900 R.P.M. this may be the problem.
*To check (have your dealer do this) - Using a dial indicator, put a mark on the flywheel
when piston is .050 before T.D.C., then check with timing light at full throttle, this can be
done on a jack-stand with brief full throttle bursts. If timing is less than .045 at full throttle,
then a larger offset key should be installed. (each .007 of key offset = approx .010 more
timing advance, measured in piston travel)
**Example: If your engine has .030 timing (instead of .050) when checked and you have
a .020 offset key installed, then you need to install a .035key, which should give you
approx. .050 timing advance, measured in piston travel.
*Important - Whenever you change the flywheel key you MUST use your dial indicator
again and remark the flywheel.
Any Engine: Please don't bother to ask us about your Exhaust Temperature Gauge.
We have not found any use for using such an instrument in tuning for performance. If the
engine is running and 1 pipe is iced over and 1 will cook hotdogs nicely... you've got a
problem.
