For you guys that want to know if this works – here’s my experience. I sent out my igniter earlier this year and with regular shipping took about a week each way with super fast turnaround. No time worries as outside was below 40º at the time. Email communication was excellent beforehand as well as on the return shipping.
Got the advance change along with a slight bump up in the rev limiter, and really think this is the best performance mod I’ve made to the engine. I’d previously done the typical external mods many of us have done: AI & snorkel removed, K&N air filter, 2 of 4 baffles removed from stock mufflers & remaining 2 baffles have 1/2 inch holes drilled, carbs rejetted (Pat's jetting calculator was right on). The bike pulls stronger and if my ears don’t deceive me, the exhaust note is a bit different too – sharper, almost like higher compression. My testing was rather simple: looking for any change in acceleration getting up to an indicated 90 mph. The bike would go past this speed in the past (it’s pushing a rather large 19” Memphis Shades) but would best be described as sluggish up there. Now it easily reaches this speed, I mean easily. Overall acceleration is just snappier, livelier – any way you want to say it - it’s just better than before with NO other mods made. If I had to describe the change in only one word, it would be: responsive. And if you don’t know exactly what I mean by that, let’s just say: faster. Oh, for the record – this is on an ‘05 SM with 10K miles on it.
