REV Limiter's ?

[Sand_fiend]

Ok, so i am putting this motor back together again. New shims, Shim buckets and the cam is being fixed after eating two shim's.

A Question of Possible over revving was asked by members here.
Mega cycles says these cams are good up to 9,800 rpm's with this set up i have.

I still believe the E-bay shims gave up but..
.
Is there a aftermarket rev limiter for these bike's. i know it is a cable driven tach.
So it must be some kind of electrical coil limiter off the pick up ?
Or what do you guys do to make one of some sort ?

just putting this out there.. Thanks..

Dynatek makes a rev limiter. I hope you aren't using stock valve springs!

Some stock GSes will go over to 10,000, so 9800 is nothing "special". :-k

It would really help to know what bike you are talking about.

Yes Dynatec make a very good rev limiter. And it' adjustable. Can't never tell when you miss a gear, or round out a trans dog. Excessive tire spin,I Back cut trans now since then. . I blew a clutch basket one time and wish I had a limiter at that time caused catastrophic damaged, Clutch basket backing plate, Oil pump gears. I was in third gear heavy load with a stock basket and it flexed taking out a lot of parts, Damaged the bearing retainer also. Cracked the ring gear and shattered the Hi Volume pump gears I think a rev limited might have saved some of it if not all. Got one (limiter) now and only turn it up when in race mode lol.

The cam is only a 380 lift with a 260 duration. the cam calls for .004". and with the new CR 31 carbs, it will rev over 10K if i pushed it, but i don't want to go that high because im told it could pitch a shim. that is why i want to limit it.

the closest i could get was 005" and .006" it did not run good at .003" or .002"

But the Bad news today is, after removing the valve i found that the Guide is cracked
