oil light

Hav you looked at th oil window how full is it?

 

I agree totally with the other guys. Just don't hit the rev limitter. Max power is at 16k rpm. You should have no need to go above 18k before you change gears - if you do then you're actually accelerating slower than you would if you shifted earlier. If you're able to redline it in 6th then you're already doing 180km/h + and would want to be on a race track.

 

Firstly, we need to establish the fact the bike is telling you something; you're killing it. You are constantly reving it to 19 RPM? You're probably bouncing the redline which is really really (REALLY) bad for any engine.

You should also be shifting earlier because by the time you pull the clutch, select gear then engage with the throttle still on, the rpm would've rose even more (throttle should still be on because you want to smooth out the revs to make for a better shift).

Also, riding like that is really not safe and don't do it on public roads (we all do it sometimes I know). But yea, you know what I mean, I'm not taking the piss out of you.

Yes, the Fizzers are power restricted to 40hp. <!-- m --><a class="postlink" href="http://www.wikipedia.com/">http://www.wikipedia.com/</a><!-- m --> has more information.

The oil light wouldn't indicate this restriction though. There's obviously an underlying issue. Don't forget the bike is 16 years old now and was probably sitting somewhere for a good 10 years (minimum) doing nothing from about 1993 until it was imported.

Anyway, I shift gears before I get to 6k and if I feel like giving it 8k. This is sufficient for me and gives me a blast (well not REALLY but yea). The only time I rev it more is when I give someone a go at the lights. Can't help it. I happily sit on 4.8k at 60km/hr in 6th gear. Just to give you an idea of what you should be revving to

Look after your bike Mate, end of the day if anything does go wrong while you're in a corner etc it could be dangerous. Check your oil levels etc again and report it to a mechanic to get it checked properly.

 

katatonic, if you're shifting at 6k rpm then you're actually doing your bike harm. These bikes are designed to rev and rev hard. There has been a fair bit of discussion on this board previously about how constant short shifting can lead to carbon build-up on the valves, etc.

You really want to shift at least above 9k rpm (open that EXUP completely). Personally I wouldn't recomend riding below 7k rpm, and there's certainly nothing wrong with revving it out to 12k rpm in every day riding.

 

Is riding at such low revs good for the botom end on thes bikes me thinks not.

 

As Casso said shift latter. Carbon build up is one concern but another is your safety. If you are crusing at 60kph in 6th and snap the throttle back you might as well get off and push. I have been in situations where a quick burst of acceleration has saved my arse. Most of these situations have been crusing down suburban streets (at posted speeds) only to have a car / 4WD pull out of a side street and try its best to take me out.

I don’t like to bounce off the limiter and rarely get that high anyway.

I just thought people should read that again. I will normally cruse at 7500 - 9000rpm higher out in the hills.

 

Hmmmmm I'll have a think about this and get back to you.

Need to get the thinking of cars out my head too. Not saying as in 6k on a bike is the same as a car but it's around 3k in a car that revs out to 5 or 6.

I'm also trying to save fuel

I'll analyse my riding and see what happens.

 

You may actually find that optimal efficiency of gas flow through the fizzer’s engine (and most other engines for that matter) isn’t at low revs. You will probably get worse fuel economy riding in a straight line for 10k's in 6th @ 60kph than doing the same distance in 4th @7~8k rpm.

 

I always remember being stumped as to why i was getting the best fuel economy whilst giving it an absolute screaming through the hills chasing litre bikes - then i realised it had alot to do with needle wear on a 15 year old bike.

I always suggest riding FZR250s with an even use of the rev range. Your only going to make issues like carbon buildup worse if your tootling the bike around at less than 6k rpm the entire time.

 

Well that explains a lot. Especially my bad fuel economy.

I don't want to get pinged by the cops for "too loud" either. Even though it's been dB tested etc and is stock. Also don't wanna get caught speeding <!-- s --><img src="{SMILIES_PATH}/icon_biggrin.gif" alt="" title="Very Happy" /><!-- s -->

 

Wow this topic has changed O_o

But going with the flow of the thread, I'll admit I always keep the bike at midrange. I almost always shift at about 10-12krpm

And boy am I shockin at changing gears at the redline -_-
I'll get it down pat, sure..
