Derestricting...

[LustyLew]

Hi,

I bought my ER-5 back in August last year when I passed my test, I had the restriction kit installed, as my licence is restricted to 33bhp. At the time I would have never have thought about removing it, but now I'm wanting more power

I guess me first question should be, on a bike such as an ER-5 would removing the restriction kit make much difference to fuel economy? There are days when I ride it pretty hard and can watch the (rather inaccurate) fuel needle drop, would running it at full power mean its going to not work so hard at higher speeds, thus saving fuel?

Also, if this is the case, how difficult would it be? I have my trusty Haynes manual, and have been quite happy working on cars in the past. I understand that bikes are a lot smaller and bit more fiddly, so perhaps this would be best left to a garage?

Cheers

meachanical restrictor kits normallly come int the shape of washers that fit in the manifold, so I would think its a case of just taking them out. On an er5, I wouldn't think the fuel consumption would be much different.

They normally fit washers in the carbs simple to remove.

I'm guessing 2-3hours with the manual? I know it didn't take them long to fit, but they screw you because you need the kit (b*stards!).

on an er5 should be an hours job at most I would reckon

[McJamweasel]

It should just be a case of tenk off, airbox off, carbs off, washers out, then carbs, airbox and tank back on.

Barring any problems it shouldn't take you too long.

Has anyone tried to remove the manifold restrictors on a ZZR600? If so does the fuel tank need to be emptied and removed to get at the carbs? Ta

have actually removed carbs of my old zzr600. You should be able to take off tank without empting it if you are careful.

Hi

Will probably take 1~2 hours.

The ER500 engine is quite upright with the carbs immediatly behind it. Same engine as the GPZ500 (basically). With the GPZ it is a bit of a pain getting enough backwards movement in the airbox to get the carbs off.

Not sure about fuel consumption. It may well improve.

All the best

It will take longer than you expect, when you take the carbs off for the first time, simply because you are not sure what to do...

The first time, on my cbr it took ages, i dunno half a day, i was working on and off though. Not saying it will take that long, but be prepared for a good few hours. After the first time it takes 1/2 hour. No probs. Its a good learing experience.

Oh yer and it really helps if you have another set of hands with you. Even if they know nothing about bikes...

If you need help doing it your welcome to come round and I will help you do it.
