Hey (lil-Vulky)

[Westy_mate]

How are you getting these speed figures?

Fanny.

Had a mate beside me in his car, got him to make note of the speed.

This is all getting a bit silly. Young bucks always like to boast about their 12" cocks, but the reality is always different.

1. A dyno reading will not give you an accurate top road speed. Without the weight of the rider, and more importantly without any wind resistance, any reading is meaningless. You can probably deduct 40-50kph from any theoretical reading. Taking a dyno reading and adding a bit is farcical.
   
2. Motorcycle speedos are notoriously unaccurate, particularly on small bikes, and particularly at higher speeds. You can quite safely assume an over-read of around 10%, or around 15-20kph.
   
3. If your speedo only goes up to 180, you have no idea at all what any speed over that truly is.

As others have said, put up a GPS confirmed speed run, not dyno-bullshit. Until then, we can safely assume that the only way you'll get your 250cc bikes to 240-250kph is to throw them out of an aeroplane from a great height.

Im not boasting.. im just trying to clear something up.
Totally aggree with you there, not denying anything and as i said before Speedoes are horrible on MC's, i beleive i had an accurate reading due to a friend following beside me, his read 220, and could prob do more but ran out of straight road (not too keen to take a corner at that speed on a pidly 250 hahaha)

But all that said totally agree with you there. Quite frankly i couldnt care my bikes top speed, its a 250, my bikes built for corners, not straight lines. goodluck with the top speed tests mate!!

Ride safe

Car speedos also become wildy innaccurae after about 130km/hr, tending to also read high. Bikes are renowned for being worse though.

I dont really care about a top speed, Im more a corners lunatic, but if youre gunna say your 250 can do 250, and keep up with a GSXR750, then youre going to called called out.

Im a corner freak too! Pity i got my hands on a MC19 rather than a MC22, my pegs are constantly scraping. sigh...

Take them off. Save you a bit of weight too.

[over5tayer]

surely you'd hit the rev limiter (assuming it has one) before you get to 250. Ive had my MC19 up to 180 (on a slight incline) at just over 17,000rpm with about 1500 revs left before it'd hit the limiter. I know MC22 gears are slightly longer and they have a few more revs at their disposal but i still dont think you'd get to 250... its a nice bike, hope you can afford to fix it up soon

EDIT: other than the 'jetted out carbs', what else has been done?

[Blackshear]

My bike does 160 indicated.

Also my dad is a rocket surgeon.

[DrunkenMistake]

I had my MC19 up to 180, took forever to get there, but thats 180 on the dial so most likely something like 160 - 155 but it wasnt limited I still had a gear left and was at about 17grand, Now in saying that, I just dont understand why people go on about their 250's doing more than 100, it takes roughly 6 and a half seconds to get to 100 depending on your weight, the road, the weather, your tyres, your fat ass ego ect, buy a bigger bike, Argument ended what would take a 250 to overtake a car, would take the likes of a 90's 600 to do twice.

I have no rev limiter....
i took my bike to a couple of mechanic friends that have worked at red baron etc, they had it for a few days and i didnt really get charged a whole lot either.

new jets,
new airfilter
carbs overhauled
new sparkplugs
new cdi
new bulbs (all LED now)
new battery (around 5 months ago)
hmmmm.... theres some more on paper somewere but you get the jist of it.

Also i might add the greenhithe bridge is on a nice incline...

didnt take too long for mine to hit 180 on the dial? but as you'll see on my dyno (when i get around to putting it up) its running really good, been well looked after, garaged, serviced etc..

mate, i would buy a bigger bike but,

1. cant legally ride it
2. cant skillfully ride it
3. cant afford it

:P but i agree with you! it is just a 250! who cares! case closed?? (please say yes)

Ohhh! i forgot to add,

new HRC racing sprockets and chain which help make the gear that little bit longer.

[nodrog:Me]

How much faster do those new bulbs make it go?

not sure! but i know that a CBR runs a lot better when the battery is fresh and not in strain hence using LED's to reduce the watts. PLus LED look cooler
