[nodrog:Me]

I wouldn't say I'm an enormously experienced rider but don't mind pushing the limits if I have to (and within reason) but found that am always losing valuable ground when dropping gears and slowing down around corners and want to ride fast out of them...unless I'm doing it completely wrong...

you should be entering the corner in the correct gear you want to come out of the corner in (ie in the powerband), not fucking around changing down mid (or after) corner trying to find the correct acceleration.

if you arent doing this, all more horsepower is going to do is allow you to fuck up the corners faster.

remember its a rs250, you will always lose ground to a more powerful bike in a straight line.

..unless I'm doing it completely wrong...

You are. The only limitation on an RS250 corner exit speed would be the need to keep the front wheel on the ground.

Quite seriously , there is NO bike on the roads that would be faster than an RS250 through the corners.

Over 200kph on the straights, litre bikes will overhaul you. But you should easily be able to retake them in the corners.

Brake brake brake, bang bang bang, scream bang scream bang scream. That's the way to do it.

sounds like friday night in south auckland

You should be able to pick one up quite cheaply, Ixion, when the learner laws change and all the n00bs have sold them for fifty notes because there's a hole in one of the pistons

I know. I am waiting in eager anticipation.

Correct me if I am wrong. I always tend to enter corners in second or first gear as to allow me to speed out of them as soon as I can.

That's one of the reason I don't redline it as I exit a corner. I rev it high enough to let me speed out of the corner. Not sure if that's still wrong...

I wouldn't say I have HP issues however would be nice to get a little more performance out of it at the lower revs. Already have a set of iridium plugs. Now when you say a full rebuild, what do you mean exactly? Tend to average around 140 kph with the occasional 180 and 200.

get a four stroke then

Given that the RS250 is probably one of the half dozen fastest bikes of ANY size, point to point, on the roads (and on some roads, the fastest), one feels that the OP must either be an enormously experienced rider with balls the size of watermelons, or does not understand how a two stroke must be ridden.

sorry timati, but i think the latter is the case

that bike needs to be thrashed and kept high in the revs

revving her out will do more for performance than a lot of mods

Am always keeping it in high revs. Funnily enough the mechanic told me that if I keep it in high revs long enough, it's a good way to blow up the engine. Which is the case and hence my confusion???

Listen to IXION really but just coz I'm bored...

Keeping it really screming is going to shorten its life a bit but thats the way it was designed, If you are worried about that you own the wrong bike.

Do some research on the oiling system and make sure you understand it, if it is going to see racetrack leves of full throttle It may be a good idea to add a wee bit of oil in the petrol to bring the oil/fuel ratio for track use but I'm not sure about this bike you own it so find out.

Keep it well maintained.
Make sure the powervalves are set correctly, the exhaust is clean and all that, if you don't know how buy a manual and if you don't want to bother buy a fourstroke.

There are things you can do like making sure the squish is set correctly when you do this top end rebuild, that will help you alot in the midrange but only if it isn't correct to begin with.



If you really wan't to pointlessly throw money at it look here:
http://www.thetuningworks.co.uk/
http://www.rgvspares.com/

Most added power will create a compromise in another area but billet powervalves could be a good idea.

But as long as the bike is running well it is almost always going to be the rider limiting the bike performace so $$ is better spend on developing skill on the track.

Then If you start racing you probably will stop caring about big man speed and power on the road because you will realise its mostly a load of shit anyway.


Mostly random thoughts there, some may help but because its just my opinion its probably mostly wrong anyway.

it's a two stroke - blowing up the engine is part of the experience


you rev it it wears out faster, you don't and it gums averything up with unburnt oil

either way it's meant to be a rebuild every 20,000km(?)

sure there's less parts to replace, but (along with appaling fuel economy, oil costs, hot seizures, cold siezures, holed pistons etc etc) having to do five rebuilds before you'd even look at some fourstroke motors kinda negates the myth that a fourstroke is more expensive

i'm a fan of two strokes but myself don't recommend them unless you've got big balls, a big wallet, and know how to operate a screwdriver

Enter the corner in the highest gear that will keep the engine in the powerband. If you are not familiar with the corner, and thus may have to slow further midcorner, drop an extra gear on entry. The thing to avoid at all costs is dropping out of the powerband in the corner.

On exit redline and bang, redline and bang, until you reach the next corner


If you don't redline it (or pretty near) you're abusing it. You'll probably have all sorts of mechanical problems, and more importantly, you risk a serious crash. Remember , you NEVER want to drop out of the powerband in a corner.

It's a tuned two smoker. You need to thrash its nuts off. Rape it, and it'll come back and ask for more.

Two-strokes do that.

But if they blow it's about $300 to rebuild the top-end.

[Squiggles]

I got dibs on a couple of RGV's


I always believed on the two smokers, its not a good idea to hold it at the same rev's for extended periods of time...gases stabilising etc, cant remember what the final conclusion was, theres a thread here on it

You're meant to redline it... thats why i "abused" your bike when cleaning it out, riding it at the peak power... rebuilds will come when they come, whether you ride the shit out of it like you're supposed to or not...

Took your advice and been redlining it and you are right, I am getting more performance out of it...only problem is keeping within the speed limit...

Two-strokes do that.

Cool.

You did more than abuse it haha. Don't hold on the throttle continuously. Am always closing it and opening it and find am getting more of a bang when it starts to hit the powerband.

Don't intend on blowing anything up haha. Hopefully I can rebuild the engine the next few weeks. Am trying to source piston rings and base gaskets.
