I've just replaced the ignition control module on my 2001 Blast and I'm trying to set the ignition timing. The service manual calls for the engine to be at 1200 RPM, however the bike does not have a tach. Is there a way to check the engine speed? Maybe a standalone tach?

The service manual also calls for a "TIMING MARK VIEW PLUG". Do you know what it does and if I can get away without one?

Welcome Vyelevich!
Do you have a service/repair manual? Set the static (engine not running) timing as it suggests. A 'standalone' tach can be purchased or on some better timing lights, it includes the tach. If you've static timed it right, the timing should be right on, it usually is unless you have other problems.

You'll need the "TIMING MARK VIEW PLUG" if you want to check the Dynamic (engine running) timing without getting oil all over you and the garage. It can be done but its messy. The clear plastic timing hole plug is the same one they've used on all Harley's for years and should be readily available from any supplier of Harley parts. *It screws in lightly finger tight*

"In terms of timing, this is extremely easy on the Blast. If you have a manual use the instructions for static timing. If you don't here goes. Remove the timing plug found on the right side behind the pushrod tower, also remove the timing cover also found on the right side. Place bike in fifth gear and rotate engine until the timing mark is in the middle of the timing plug hole. Loosen the ignition module screws and turn on the ignition. Do not start the bike as it will puke large quantities of oil from the open timing hole. Slowly rotate the ignition module until the LED lights up I usually do this 2-3 times to make sure I don't over shoot the mark. Tighten and replace plugs screws etc. and go riding."

I've forgotten to put the timing plug in a few times. Usually it's when I'm swapping ignition modules and I set the static timing, and do a quick check. I do a lot of that! Anyway, after about 5 or 6 times of getting oil sprayed 10 feet across the garage and all over my wiring, I've gotten good at remembering to check the plug.
