skimmer....

I used their list as a basis for my worksheet... theirs' wasn't specific enough, nor did it list prices... or get into the options of carbs, coils, petcocks, etc...

I got the link to the outlaws from them too...

I have a compu-fire ignition system ...... it has, like all these after market ignition systems, adjustable advance curves, and rev limiter

I put mine in in June this year and have about 10K miles on it. As of right now, I wouldn't part with it or swap it for another brand.

Compu-fire is also less expensive than some of the other brand names mentioned

my 2$ worth

you're welcome

this should be a rather interesting thread to follow to say the least. At this point I almost wanna ask why not sell the bike and buy a carbed bike a bit older?

Thanks man...!!!

Mike - I could easily be in over my head, as you know I have an EVO ...... so for what this is worth

The speedo is picked up off the tranny, has nothing to do with ignition. I would suspect that yours is also. This reduces the mechanical components in the speedo system as it is a magnetic pickup sig off the tranny that is sent up the cable to the speedo


if you have a tach on your bike, or plan to add one, you will need to make sure that your ignition wiring (coil hookup) has the correct feed for your tach.

On the EVO, the stock sys uses a dual fire system (both cylinders get a spark every cycle). So the signal that is sent to the tach has to be such that it only reads HALF of the firing sequence in order to correctly indicate the RPMs of the engine.

Conversion to single fire (only one cylinder fires on each cycle) so you are now only getting HALF the pulsed from your coil and you need to feed the tach from the center post of the single fire coil


or something like that

I ran my tach (rk) off the pink wire on the harness.

Thanks for the input, Mikey... I don't think anything translates over to the '04 and later twin cams though...

I check Compu-Fire... nothing... the '04 and later twin cam uses the speed sensor to run the speedo, signals, and other crap I haven't figured out yet... basically, a mini ECM inside the ignition to do basic housekeeping stuff...

I'd think about an FXR except for that pesky bolt problem... a guy shouldn't have to travel thousands of miles to find someone who can remove it... too similar to finding a guy who can tune an EFI...

With over 40 grand invested, he's trying to make it an even 50.

re.

So do FI tanks really hold 5 gallons? The fuel pump is small, but would throw it off a little.
