Switchable restrictor.

[_Iain_]

Is there a suitable spark cut rev limiter on the market for said purpose.

Basicly two stage rev limiter, stage one at the redline, stage 2 (used for launch control normally on a car) at whatever point on the dyno graph the bike makes 33bhp, at a guess around 6-7k revs. If the plod pull you up, flick said switch or plug a wire in behind the headlight and instant 33bhp. Takes 90% of the risk out of riding derestricted is the thinking...only way you'd get shafted would be if you couldnt flick it between modes.

Workable?? Diddnt the RS125's have a simmilar restriction on the ignitions? More than happy to invest in dyno time/2nd hand limiters to test the system, but is the theory sound or am i missing something major??

You could achieve this with restrictable washers. A custom manifold I guess? Pull a slide and it slides the restrictors in the way of the air flow, push it and it puts them out of the way...

If not you could always try a removable throttle stop.

[_Iain_]

Power commander would require an EFI bike, and cost silly money.

Manifold would work but serious amounts of fabrication and general arse ache. Throttle stop would also work, but having done that to a car on the pedal and had it jam up and stuff it's too risky.

The reason i ask is that the rev limiters pop up on ebay for sub £40, and would be a 15min job to fit...if that. Easily transferrable between bikes.

You would have to prove (if you crashed) that you were on the 33hp map though, with no definitive restrictor in place your arse would be introduced to a cactus by the 5-0

As said by Rob, just kill the connections to two of the HT leads by ripping the leads off with a bit of thin rope or such attached to them. It's quite unlikely they would dyno the bike unless they had reason to believe it was massively over, probably coupled with a bad attitude on the part of the rider or cop. Also, don't forget, you can ask for a deferred inspection, so the police can check the BHP in say two weeks time at a police station [during which you install the restrictor]. Oh, and restrictor certificates are NOT legal documents

Messing around with removable washers will just cause loss of pressure between the carb and the head, so the engine doesn't run at all!

If your caught out you would be screwed the law are strict as fuck when it comes to the 33bhp kits, if you in a accident and the take your bike away for testing which they do sometimes and they find the switch u fubard. just put up with the restricions you will still have decent bottom end and its only last 2 years.

The police know you can get restictor kit certificates off the internet and if your involed in a accident they will check, a lady that helps out at the charity i work for is a coper and a bike she knows all the shit they do as she gave me tips trust me if u chrash in a car they will test and they aint thick if u have a little switch sum where they will find it, the tester would be a mechanic.

you could replace your cdi with a micro squirt,
they are made for doing fuel injection, but they work just as well just doing the ignition,
it would mean you'd have to set it all up, but completly possible to do,

nothing off the shelf though

If your licenese is restirted to a 33bhp and your riding something over that your breaking the law. its as simple as that. The certificate is something your insurance might ask for. my point is the police know that you can get them off the internet for 30 quid which people do incase they get pulled and asked to show that the bike there riding is "legal" but if your in a accident and the police check, uv got points on your licnese and a fine, and who wants that. ITs bes tjust to put up with the 33bhp its a gud stepping stone till your 2 years are up then u get a bigger bike. 33bhp itsnt to bad i still cud do 95 on mine and got to 60 so fast it made my eyes water.

wouldn't be too difficult to make tbh, so long as you have cdi ignition. Reckon you could make it for less than £30

[BanditMonster...]

Im just trying to give they guy warnings. If a police officer that is a biker says it i wud trust her. She oviously knows about they law or she wouldnt be a police officer, you know. Im just trying to explain to him that if hes caught driving sumat more than a 33bhp he will get in trouble. if he still wants to do it, its up to him.

What bike are you planning on getting, my hornet is restricted and still pulls like a train, and it acclerates nicely too. In my opinion its not worth the risk.

Ive gone from a GS500 with 33bhp to a Bandit 600 I notice HELL of a difference but going for a 125 4stroke the gs felt like it went like shit off a stick, buts its wat u get u have a 33bhp restictor ur going to get 33bhp, once youve servered your time on a 33bhp u can have ur fun
