    Need a really good exhaust and some general advice.

    I have purchased a new Honda. His name is "Gary" He is a MC22 CBR250RR 1992 model.

    I would like to put a really good exhaust on him to make him sound really good. Anyone would recommend a good light weight 4into1 full performance system? I do not want a cheap Chinese one, but a good quality one, I am looking at around $800 maybe a little more if its worth it.

    Having never owned a high performance engine like the one in "Gary" I am unsure how to really use the RPM band to make the most of its 29kw. I have been told the engine doesn't like to be "labored" (Can someone explain what is meant by labored?) I am worried about going through town at 14,000-18,000rpm and annoying everyone, yet I have been told going lower around 8,000-10,000 can hurt the engine. I have been warned the plugs can fowl and cause a misfire and internal engine damage. What i am asking is does anyone have any advice on how I should use "Gary"?

    I was thinking....not the best choice naming your bike a male name. Then realised it's you, battleship girl

    Re: Need a really good exhaust and some general advice.

    Ahhh good bike. Near to the last of the powerful 250cc Hondas I think.

    A couple of my mates have had them and they're a great bike.

    Just service it with some top quality full synthetic oil like Motul and it will look after you.

    My mates seemed to think there wasn't much power to be gained from the exhaust system as Honda did a pretty good job from factory. One of them just changed the muffler to a carbon one for a bit of bling and noise and thought it made the bike a bit sluggish down low.

    Dont be afraid to rev the bike and keep the revs high when just cruising. The RPM is high but its all relative to the revlimit (much like your B16A Civic which cruises around at +3,000 rpm but has a 8,500 revlimit). Your plugs certainly wont foul up if you ride around under 10,000rpm though.

    Kiwibiker is a really good forum with good people and alot of helpful information.

    Enjoy your bike, take it easy and dont be afraid to spent a TRUCK load of money on good riding gear - it makes riding more comfortable and fun + could easily save your life.

    Re: Need a really good exhaust and some general advice.

    ^^ Thank you very much.
    I really appreciate the answer.

    I have some good pants and a jacket. Safety is very important.
    When i test ride Gary i was amazed at the 19,000rpm redline. I admit i was afraid to take him all the way up there. I have joined kiwi-rider forums.

    He is having a full service, new plugs and a new battery today.

    Nice! Yup the first time you go above 11,000rpm it feels really strange and anything above 16,000rpm feels like you're destroying the poor engine haha.

    Re: Need a really good exhaust and some general advice.

    I was going onto the motorway from Te atau on ramp, came around the bend and then gunned it, MY GOD the noise and the needle, 13,000 , 14,000 , 15,000 and honestly i was scared but it kept going all the way to 18,500 when i changed gear.

    what would your advise be on driving Gary around town, i don't think people would like me been at 14,000rpm with in the city.

    Re: Need a really good exhaust and some general advice.

    Just have the RPM where ever it feels comfortable for the motor. A stock one isn't THAT loud riding past. You wont be full throttle or doing massive down shifts around town so you'll be fine .

    Just ride and enjoy .

    Re: Need a really good exhaust and some general advice.

    Just going a little off topic here, what's the reliability like for a 20 year old 250cc engine? how do they handle the mileage? Are they shot by 50,000km or are they ok because everything's so small in the engine the forces involved are minimal?

    Re: Need a really good exhaust and some general advice.

    I have very limited experience, but I am going to comment anyway - I have owned a Honda XL75 from since I was about 6 years old, and that thing have been seized solid from heat on more than one occasion, yet it starts first pop the very next day - i would consider them dam near indestructable! but yea, that is the extent of my opinion

    Re: Need a really good exhaust and some general advice.

    I just saw this thread.

    You aren't going to get much gain from the exhaust unless you do some work to the jets in the carb.

    If you just want a bit more noise, just drill a few holes in the end of the muffler.

    I have a MC19 which shares the same engine. I dont really rev it over 15-16k as the power starts to drop off.
    Around town at 50kms i put around in 5th and 6th gear and its sweet.

    These engines are pretty bullet proof even though they are getting on in age. But 45hp at the crank is pretty good.

    Re: Need a really good exhaust and some general advice.

    And a dry weight of 142kg so yeah not bad.

    But by the time you add a 80kg rider the specs look a lot more poo.

    Re: Need a really good exhaust and some general advice.

    Re the labored aspects, I assume if the bike is trying to perform "under load" in the wrong gear or too far down the rev range, it will need to work harder to maintain and or gain momentum which may place strain on the engine, but you need to remember bikes are not cars and they rev very high, I had the same feeling at first when I had mine, it felt weird riding at such a high rev range, but you need to as bikes are not cars and you don't have a second chance. You always want to be able to accelerate away if a car or truck pulled out and didnt see you ,if you're in the wrong gear not much is going to happen on 250cc bike - unless you can hit the brakes and not slide.
