so were positive cutouts . solid block tyres and  carb throat restrictors . how long did any of those compulsory items last ? . I'm guessing from your eagerness to promote them ,Briggs is involved somewwhere along the way ,

Rev limiters were tested a few years ago by a couple of riders at a couple of tracks & initial reports were favourable. D Howe was 1 of the said riders.

I don't doubt that on certain tracks etc they would be favourable, namely slick tyre shredders but were the limiters tested adjustable? Which of course would offer riders a choice rather than the newly proposed limiters at the top of any usable rev limits and therefore rendered largely useless.

the best way to limit revs is with your right hand ,  if you get that right you become a great rider like hans neilsen ,  I saw him break a couple of track records never heard his engines screaming for mercy at any time though . on the slick or knee deep in dirt

STUPID remark. I am not promoting them, wouldn't know a rev limiter from a banana and don't have a view either way. Just stating the facts which includes that several riders and tuners are in favour, believing that they will considerably reduce wear and tear (at the starting gate) and reduce costs.

tuners of course ,££££££££££££££££,.  care to name any riders Or in fact any ex riders who are in favour ?

WILL do so in SS before long ...

I wonder if the reason they are being brought in, is not necessarily to reduce the cost to riders, although a rev limiter may help with wear costs, but the main reason could be to try and level the 'playing field'.

very much doubt it , rev limiters work ok  with petrol and on tarmac ,  methanol is  whole different ball game ,  and riding on a loose surface where a consistent level of spin means you can safely steer .  how many times have you seen riders with the front wheel off the floor mid turn , yanking on the throttle to get the back wheel spinning and the front wheel back down , try doing that when a  rev limiter kicks in !!

APPARENTLY Freddie Lindgren won an SGP with a rev limiter fitted...

Yes, at Scunny.

Also Josh Auty has been using them.

Will you also name those (if any) that are against them (genuine, unbiased question!!)?

Not going to trawl through the regs but is there anything in place at the moment that states rev limiters are currently allowed? Could they not fall under traction control which is not permitted at present?

[StevePark]

I (kind of) remember a few years ago at Exeter, when Newcastle were there, that one of the Falcons riders was using a rev limiter and the Diamonds management complained and he was told not to use it as it was "giving him an unfair advantage."  I think the rider was Seemond Stephens, but don't hold me to that.

there is a rule that ignition must be from a single source  and  static ,  rev limiter could fall into that category , about 3 years back Martin smolinski had a Polish button fitted , (advances the ignition ) and Holder and another whining aussie  reported him for cheating , several of the Poles had been using them for a while unnoticed   ,remember those blasts around the fence from Gollob   and everybody wondering where the extra speed came from !!

The static means the ignition timing can't be adjusted on the fly, only manually  at  standstill. The single source bit I think is pretty much the same as the static rule in that it stops the rider switching from 1 ignition to a secondary ignition on the fly. So not technically adjusting the ignition, but switching between 2. Much the same thing.

As adonis said in a previous post, rev limiters work fine on tarmac when the wheel isn't spinning. On my road bike all it does it makes it feel like the bike is misfiring and the bike won't pull anymore. But a speedway bike needs to be spinning to turn the thing, so if it did cut in mid corner, in theory the bike would grip/stop spinning for a split second, but in that time will it be enough to launch the bike ?  I've only rode a speedway bike on a field, badly, so it would be good to hear from someone with more knowledge on the limiter thing .

The soft limiter cutting in first would be like a fairly minor misfire so you should have plenty of warning. Every other off road bike has rev limiters including our flat track bikes, because we have less tyre grip though it's a fair bit different and we would usually gear to hit the limiter twice a lap at the ends of the straights on Speedway tracks. As pointed out though the Speedway limiter is to be set so high that it won't come into play once away from the gate.
