Decide to do a service today,only because I am not drinking (can you believe it? )
Thanks to my modification, six bolts unscrewed and air filter can be changed.Easy.Change ignition coils to "plasma"coils from "ignition project" company. Can't say I notice significant improvement.May be I need ignition amplifier.Later will try to wrap exhaust manifold Change all bulbs to LED.Cannot think of any improvements,or mods. If someone have any idea please share.
