Gearing up- the best way?

[Danger]

Std gearing is 14/48 which is what I run but don't compare apples with oranges as different bikes have different internal gearing.

true, hadn't thought about the internal gearing. Have you tried a few different options and settled on 14/48, or did you just like it std?

Sorry for stealing the thread courts.

Never found reason to change with the six speed box providing a gear for every occasion. I've heard of people gearing them up with a 47 or 46 or even 45 rear to tame the hit, but I tuned mine with a straight taper needle rather than trying to tame it with gearing.

sweet as think i will tweak with the intake and exhaust before adjusting gearing - we shall see-- in search of that hidden extra POWER

You coming out this weekend then mate?

at the end of the day, 250 4t's arent rocketships. this is exactly the reason why they make 450s. or if your after fun and power, this is what a 250 2 stroke is for.

once again depends on your usage, body size etc.

LOL his last 2 stroke was a old KX that he would start and ring the shit out of to heat it up.

i know a guy who used to do that. he learnt one day when it siezed.....

[cheese]

I'm running the straight taper needle (per your suggestion, thanks ) but I've also changed the gearing to 14/46. Conditions down here are faster than I remember in Woodhill etc. Bugger-all tight single track and lots of flat straight runs in amongst the killer hills. I hardly ever use lower than 3rd. At the beach racing and flat-track I was running 14/44 and still topping it out, a few km faster than the 14/46 was hitting.

Now that the jetting is sorted I might go back to 14/48 for general use, as I miss the extra snap of the lower gearing.

[Danger]

Sweet, wondered how you had got on with that jetting.

Your CEK-based settings were a huge improvement and basically sorted it, but now I'm used to the bike I find it a bit soft. I've been adjusting the powervalve for more hit at times, so later I will go through the process of trying to jet it accurately using a more aggressive (DDK?) needle - as much for my own education as anything.
