picking up a new 250sx tomorrow and its going to need more top end, im happy to lose bottom end coming from my yz250, I hate midrange motors, no im not racing I dont care bout benefits, I like a 125-150 all top end power band and want the 250 to have the same feel of "wham its on all the way to the top" and have a gnarly hit. Wham it's on.
What kind of pipe to change? not lookin to put tons of money into it just the basics, pipe, silencer, jetting airbox mods and race gas? MR12 is big in my Superbike racing scene but thats for 4 strokes... Im fine paying 15$/gallon to pour in 10% hp....
Only play riding as a vet and want a "fun exciting" bike instead of a "fast" bike
cheers

I'm going to build my 250 , a lot like I did my 125. The stock exhaust sucks , so that's getting replaced with another Scalvini pipe and FMF 2.1 power core ( non-shorty ). The reed's will either get the pedal's replaced or pick up a Gforce 4. A possible head mill from .065" stock , down to about .045"-.042". The Mikuni carb is going away as well , and I'm going with another PWK 38 , along with Derrick's STIC mod. I believe after these changes , the bike should be running pretty strong , and I should be able to swap down to a 40:1 , 927 mix with race gas , instead of this synthetic shit at 60:1.
If you build your's thew right way , you won't need to ride it like a 125 , where it's wide open every where.....unless you plan on lining up for a national. And if you can?......then good for you. But a well built 250 2 stroke , can go faster than what 99.9% of the rider's out there can handle wide open around a track.
Just my $0.02.
Im just looking to make the thing NOT want to short shift as it does now and every other (250 ive rode) but rewarding to rev all the way to the top.
Pit Row
If this is what you gents are recommending..... then consider it on order.

Also looking at the RK head.
Also I desperately need a quick turn throttle for this, I have wrist issues and need quicker rotation, dont need a cam system just something much faster. Please advise.
