Stumble Bumper?

[baylensman]

So Ive had a few of these bikes now (three is a few right?) I find that the Stumble Bumper (rev limiter) is in exactly the wrong place (rpm range) for first gear.

I mean for me personally If i hit it hard (chuckle head next to me at the light) I generally keep up with or smoke most others, until i go to make the shift, just as i start to move for the shifter and clutch, the rev limiter kicks in. Now on my '96 I had put in a DYNA box and moved the shift point up ( not much from like 41 mph to 47mph, or a couple hundred RPM) it made all the difference.

Now i've been looking I don't see the old dip switch programable DYNA kits anymore. Just the ones that have a USB dongle and are programed from a laptop( and cost well over $400.00). is there any other way to move the rev limiter up a bit? I know on the mid 90's Z-28s the rule was don't cut the green wire. On some of the fords you just had to pull a plug. (although I'd never do anything to defeat an EPA device)

I'm not sure with the RSV/TD ECM. But the FJ 1200 I use to race (the engines are used in 600 racing legends cars) the "old" oem black box rev limiters were @ about 11k. What happened in fact was the limiter was 11k, but if you banged off it several times the next time it was a bit lower say by 2-300. They would drop as much as 900 rpm or so. 40 plus mph seems a bit much, but I guess it keeps the cob webs out. I didnt have a tach on my RSV so I have no idea what I shifted at, but I can tell you I wasnt banging off the chip.

Oh i hit the chip in first gear three or four times a week!! it just seems like the power comes on quicker than i can move my size 13's to the shifter
