Husqvarna 266xp - Stihl MS440

[wrsni]

Does the 440 have a port out the front of the muffler?

 

No it doesn't. Working just fine with the 24in bar at the minute but I'll certainly keep that in mind.

 

The choosing between them thing is just that I've a little Dolmar 109 which I've had from new so I'm not parting with it, and I don't REALLY need three saws at present, and I only bought both with the intention of choosing and keeping one. However.....

 

wouldnt part with either.

 

I believe this actually is the answer!

 

Thanks for all replies.

have both it and your bike ported.

 

Not necessary, HRC card in the ignition, HRC wiring loom, and Dogfight exhausts (all three of which I have), do the job.

 

But thanks anyway.

All of which would make that thing fly if ported correctly.

 

As for your 440 - do not just 'think about' the dual port muffler - do it. The saw was originally designed to run with the dual port(which is available from the factory affordably and is a simple bolt on). It was choked by the EPA afterwards. Your 440 is basically a neutered 044 mag. The dual port muff and a retune will make a huge difference. You spent maybe a few hundred to get 20% more horse power out of your bike? On that 440, you could spend 50 bob and get 20% more power.

With respect, you don't seem to know what a Honda MC28 is?

 

As for saw, if or when lack of power becomes an issue I will certainly look to replace the silencer as you suggest, but at this time there is no issue. Although interestingly I was setting the carb on it today and it needs quite a lot more fuel than the factory setting so maybe there's something done internal already.

 

Thanks again for the tip.

And they were ported to race. What ya have is a 'detuned' version of what the tracks saw. Same with your saw. It's a detuned version of what was once available to professionals. That's OK, if it works for you, it works for you. After using the real deal, I just can't go back.

Not absolutely sure ( just butting in here ) But is it an nsr 250 , originally about 45ish HP tweeked to give around 60HP ? An nippy package if I recall ...

That was the case with the previous 16, 18, and 21 models, but Honda knew this would probably be their last two stroke road bike, and badly wanted to put one over on Yamaha and Suzuki once and for all in the Japanese 250 "production" championship so for the 28 Honda decided to do things a bit differently.

 

Instead of building a 45bhp road bike (maximum hp allowed under the Japanese licensing system) and tweaking it for racing, Honda built a small number of road legal RS 250 race bikes and then restricted them for licensing purposes. So you've "road" settings and exhausts for 45hp and then the HRC card in the computer combined with race exhausts lifts you to it's proper capability, somewhere in the region of 75 to 80. The guy I got it from has owned it from new and he also races a full blown RS 250 and says with the HRC card, race exhausts and jetted right, there's little between them.

 

So far I've only run it in 45hp mode but sometime I'll put the kit on it and do a track day with it just for the hell!
