Can my rev limiter be adjusted

[Orange Guzzi]

Is there anyway or a replacement for the stock ignition modual that will soften the blow or the rev limiter?

[GuzziMoto]

On what bike?

I believe the ECU kits Cliff sells offer the ability to adjust that, but since I have yet to build mine I am not sure.

96 carb sport.

 

Quite surprised there is so few choices on such a bike. May try to fit a ignition from another bike that is 90 degree v twin. the vaccum advance is the real problem. few choices outside of the stock setup. On wildguzzi there are several discussions on the digiplex. no one discussed the rev limiter side. just various timing curves of various bikes. even that is some what vague. only a couple of charts with resistance values.

 

I subscribe to cycleworld mag and I thing this would be a good question for their expert.

Cliff does/was doing an ignition module for non EFI bikes called "Rec-Ignition Module",it took a bit of finding but it is mentioned on his site under Latest Developments (18th June 2005).

Orange,

 

At what RPM would you like your rev limiter to cut in?

 

I don't recall ever bumping mine, and I ride it pretty hard.

I've only run into mine once, on a long stretch of highway in top cog. It definitley hits hard enough to scare you...

[GuzziMoto]

The original question was is there something that would soften the hit of the rev limiter. That is not the same as moving it. While I prefer to NOT hit the rev limiter, I do understand why you might want to do that. A hard rev limiter as most bikes have is abrupt and not kind on the engine. A soft rev limiter cuts power gradually and is easier on the engine and the rider.

As mentioned before, Cliff might have something that could work for that. First thing I would do would be to contact him, not some idiot answering questions sent in to a magazine.

Hard limiters typically cut ignition, soft typically cut fuel [to one or more cylinders] or retard the timing.

 

Hard to cut fuel on a carbed Sport, a programmable ignition would give the user the option to adjust the timing on an rpm basis. Don't know if the carb Sport EI black box is in any way programmable...

[GuzziMoto]

I doubt it is but I would think the unit from Cliff is programmable. You might be able to tell it to retard the ignition smoothly instead of cutting it abruptly.

I found a cure for my rev limiter. I replaced the tachometer. It had been bouncing and final quit. When I replaced it, the bike started running better and the rev's past 7,450 rpm's.

HUH? if you guys are hitting the rev limiter then ya not riding that well... by the time the limiter kicks in ya way past max power, ya wasteing ya time

[helicopterjim R.I.P.]

ya way past max power

 

You mean max torque - power is different and it peaks at the top of the rev limits ....

[fotoguzzi]

I thought max HP was around 6500 and max torq just under that.. that's what my seat of pants feels like..

[Orange Guzzi]

I was blaming one problem on another apparently. The replacement tachometer cured the intial problem.

Have a look at the dyno runs HERE and you will see that max HP is normally achieved at or just shy of maximum rpm.
