GS500 is restricted how to make it "normal"?

[Graugaard]

Hi! So my bikes got 2 metal rings between the engine and the carbs... (one for each cyllinder), if i want it to have full power since that is legal for me to ride, can i just remove these to rings and then all will be fine? or should i buy diffrent jets and all kind of stuff?

[The Buddha]

They restricted it with a sort of restrictor plate ?
OK if you know what jets are in the carb post it here - manual for your country will have that.
Cool.

Yea rings just like on this picture:

Well they mix the air/fuel, one is for idle, other is for mid rev and main jet is for the larger ammount of throttle. I THINK :X

but could i just pull them out and then it would run fine without adjusting anything?

That washer - yea yank it, I think it needs the carbs to be jetted properly and it just lets it never get to the highest flow it is capable of.
Look for jet numbers in the manual, I suspect it is done same with the rest of the bikes in your country.
In the US spec bikes, they are jetted lean to start with ... We re-jet original stock bikes.
Cool.

Several ways to restrict a GS5. Intake plates, slide limiters, modified slides, different jetting, sometimes on their own and sometimes as a combination.

There was also a restricted model that came straight from the factory, the GS500E-U. Its rumoured that this one uses a different ignition module but I have never been able to find out for sure.

Take the plates out and see how it runs, if its still not full fat you need to look at other parts.

Tell me what country you are in The VIN no and the ID no of the carb including the E no and I might be able to tell you if the bike is the factory restricted model and what the stock jet sizes for your bike should be.

I'd agree with sledge pull the washers and see how it is, while the carbs are off note the jet sizes and how many holes are in the bottom of the throttle slide, I also have a restricted gs from the previously restriction laws in the uk, mine unfortunately was the throttle slide and jets, tbh I can't tell it's restricted it runs fine, is smooth till 7k then sort of hits powerband till 9-9.5k, I've managed just over 95mph on the motorway(highway) but started to get a slight front end wobble so backed off.
Hopefully yours is just the washers as it's the easiest and cheapest way to restrict the bike but it can leave the power abit lumpy and less mpg than a stock bike

I don't understand the need to restrict a GS500?  It's not a very powerful bike.

Some countries have different levels for motorcycle licenses. Along with that, in certain classes of license you are restricted as to the horsepower of the bike. Some from Europe or elsewhere can elaborate on the licensing system.

I have a pair of restrictors one member in Europe sent me for my collection. They limit the air going in which effectively limits the power. They are similar to the ones shown but go between the carb boots and the head.

Limiting the horsepower of a GS500 lets you ride a GS500 on a restricted license. When you graduate to the next level, you can remove the restrictors.

It could be good here where newbies get a liter bike and crash it because they can't handle the power. Like you get your first car license and get a race car before you learn how to properly drive.

I'm riding a UK restricted GS500F and have not bothered with getting the restrictions taken off as it would make very little difference.  It is a slow bike, not much is going to change that!  Having been used to a FJ1200 and Triumph 955i triple, the power is rather soft and very limited!  But, it is the perfect commuting weapon and is still fine for riding up to South Yorkshire when I visit my brother there.  Lovely bike as it stands, so not going to change it. Also returns an honest 60+mpg every time.

[The Buddha]

It was restricted with a 5 degree static advance over 12 degree in the CA bikes. However Not igntion box - those are hard to mod for country to country.

Cool.

I understand what you mean because in Australia we have a similar licensing scheme, although the GS500 is a learner approved model. I completely forgot that some other countries have tougher restrictions!

IMHO though, the only thing that could make the GS500 not a learner approved bike is the wet weight of the F model, 200kg can be a bit hefty for someone just starting off. The power is pretty reasonable, but oh well.

Now that I think about it, the Japanese licensing scheme would put the GS500 in the upper end of the system, you'd need to pass a motorcycle test on a 400cc+ bike.

Out of interest, what other bikes have you ridden through your riding career adidasguy?

Don't most euro countries have a 33bhp beginners license? GS has 48bhp stock, so not a huge step but it'd definitely make a difference.

Most Asian countries have ridiculous laws on limiting beginners. They have a few classes of licenses you have to move up, I think it's mostly engine size there though, not power bhp ratings.

People restrict GS500s? They barely put out enough power to get to 80 mph in a light breeze without struggling. They're so underwhelming it's almost embarrassing. Don't get me wrong, I love my GS500 for what it is - a commuter that's good on gas and easy on the insurance. It just blows me away that the gs500 puts out enough power to be restricted.

There is absolutely no way any stock GS500 puts out that much hp at the wheel. No way at all.

Which?

Bone stock I got mine up to an indicated 95 mph and it was only running 7.5K RPM; granted it wasn't the best on acceleration, but a rejet has vastly improved that.

[GS500F2004]

The top speed I have achieved on mine was 180km/h which is over 111mph, and it wasn't that difficult. It was in the dead dark of night, and I throttled off because I wasn't sure how straight the road was, I think I could I have pushed it past 185km/h. I was very tucked in and I only weigh 75kg.

If you're struggling to go past 120km/h, there is something wrong with your bike. It will very easily pull past that.

After around 140km/h is where it starts to lose its pull, but it will still keep going, after 160km/h the acceleration is slower, but it will get to 180km/h in a few seconds.

I was watching Blokes World on TV and they said Vietnam has a 175cc limit for everyone.

That's not most...

In fact, I'm willing to bet good money that most Asian countries do not have any kind of restriction or even a graduated licencing scheme for that matter, and in the cases of the very few that do, it's not really enforced. I'm not blindly saying this either, I have lived in various places across Asia whilst growing up.

Whether you need a Hayabusa on Asian roads is a different argument altogether though

Hate to bring up an old thread - Does anyone know if the Australian GS500F's are restricted at all?

The GS500/F's are not restricted in Australia, they are approved for novice riders.
