Hi all,

I have a 02 model GS500 (E?), with a 04 registration, I'm the 2nd owner apparently.  I just changed the oil (not the filter yet as they sent me the wrong one!), air filter, sprockets and chain (stock DIDs) and thought that this would solve my problems:

1.  It would not go beyond 8/9000RPM - the new air filter solved this - the old one was from a 250 I was told by the guy who changed it.

2. It will not accelerate beyond 120Kmh - now it does 130kph down hill.

It accelerates mighty fast to 100 / 110 but after that it's pointless twisting the throttle or changing gears, it will not really do anything beyond 120kph.

I've read the forums and people have said they can get this bike to 180+ - now I don't want to do that speed but I would like to be able to overtake people doing 100/110kph on my commute to work.  I like to get back on my side of the road as soon as possible, not hang around beside the driver of the other car.

Any ideas?

Thanks,

Alan

Man, not sure.  I know my bike easily hits 140+ but I stopped her at 145,hehe.  She is new and I must break my lady in easy and with love and not just take her like an animal!

How many miles does the bike have?

Has it sat for any length of time without being attended to?  My guess is that the carbs are gummed up, preventing normal fuel flow.  A thorough carb cleaning would fix this

It's definitely not the year or model.  I've got a 2002 GS500K2 and it will EASILY surpass 120 km/h.  If your registration says '04 and the bike is actually an '02 you may want to match up the VIN with the registration.  It's not uncommon for stolen / wrecker yard bikes to get the year of the bike switched up.  Then I would go to your Transport Ministry and get a history on the VIN which is stamped on the engine block and/or forks. 

Hi,

QuoteHow many miles does the bike have?

~ 20k: 50% of which are mine

QuoteHas it sat for any length of time without being attended to?  My guess is that the carbs are gummed up, preventing normal fuel flow.  A thorough carb cleaning would fix this

I've used it every day for the last two years, since I got it really.  I do about 30k per day on average and the odd trip across the country (which is at most 200k where I live ))

I got the carbs rebalanced lately, the guy who did it is no suszuki mechanic but he seems to know bikes.  That made a differnce to the low end, i.e. it got to 100/110kph much faster.

Do you still think it could be the carbs gummed up if I use it reguarly (in heavy rain)

Thanks,
Alan

If you've always had the problem, the carbs may have been gummed up ever since you got it.

Riding in the rain should not make a difference.  If the carbs were already dirty, even riding it everyday probably would not reverse the problem, only taking them off and cleaning them would fix it.

It's not often I get a chance to ride at that speed but it wasn't, if my memory serves me correctly, always like this.  I got it to 160 when I bought it.  I do know that a lot of my problems started after my 'dealer' had it re-shimmed.  I'll  give the carb cleaning suggestion a go and see how that works out.

Excuse my ignorance here but: would the old air-filter that was in it (for a 250cc) have rendered a segment of the carbs idle and allowed them to become gummed up through not utilising the extremes of their ranges?  If that makes sense to anyone!!

Thanks
Al

This may be the problem too.  In fact I would check the carb settings first and clean the carbs while you're at it.  If everything is stock on your bike (exhaust, air filter)  I would go back to the stock carb settings, at least to start with.  Make sure the person doing this knows what they're doing (i.e. what should be stock).  You can do it if you feel comfortable with it, and there are lots of people here who know the GS carbs in and out that could help you along the way. 

I don't think a different air filter would underutilized areas of the carbs, just reduce airflow.  What kind of a 250 filter was it anyway?  Did it slide into the airbox like stock or was it K&N style clamp-on filter(s)?

I'll get someone to take a look at it for me, I wouldn't be comfortable dabbling with it at that level.

It slid into the airbox like the new one does, but the bore (if that's the term) was only half the diameter of the replacement.  It hit 10/11k rpms no problem after that.  He reckoned it could have been from a bandit or something like that.

you have had it two years .. have you checked the plugs or any thing like that on the bike lately ? this is probly not the problem but it would not hurt to check and its easy

hi.,

yeah put in two new brand new ones last week!

I have 2000 model GS and i did 200km/h top speed 4 week ago. I think u need to little trust your bike.

One more thing to check, is are the sprockets stock?  If the previous owner has changed the sprockets, it might not be able to reach that speed anymore, but it should get there faster...

Hi Yip, 16/39 - the chain needs a link removed alright but that shouldn't be the cause?

you didn't state what country you are in.
does the gov. have bike HP restrictions for learners?
you are using KMH....i'm guessing europe....

maybe you have a 22hp learner GS
the reg/year mismatch is another problem.....but if your ok with it....

Hi,

I'm in Ireland, no the bike is not restricted in any way that I know of - the reg / year things seems to be that the bike sat in the suzuki import yard for a year or so before a dealer purchased it.  That's all  I've been able to find out about it anyhow.
