probably not an easy mod to make a slipper clutch for the mc22. why do you want one?

yoshi no longer do a pipe for the cbr250, but you can get ones from china with yoshi stickers...

or get a roo racing, or megacycle, or racetune etc. pipe that is made for the cbr250.

you can do a bit of cutting and welding to get another pipe to fit also if you want to go down that road.

back wheels locked up on me couple of times downshifting going hard, of course could learn to time down shift better but seen em in magasines and stuff on all the bigger bikes thought might be worth gettin depending on price of course.

id prefer get pipe that fits rather than cuttin or welding il have a look at them ones nice one

well if that's the case, +1 to Glenn, learn to blip.

Rev matching, when done properly, not only sounds cool but it makes riding even more fun than it already was and feels good and makes you look like a pro...

Plus it's free.

I remember reading that racers back in the early 90's used to use the "hop" when down shifting hard to set up the bike for a corner.
Dunno how true that is cause I would have thought it would unsettle the bike and maybe cause a high side.

Anyway +1 to blipping the throttle.
It's a case of technology vs technique.

blip your throttle dude as you downshift...

takes abit of practice, but essentially you're locking up your rear wheel cause you're not matching the engine speed to the speed that your drivetrain and wheel is going. When you pull in the clutch to downgear, obviously your engine speed will drop right? but your wheel and gears are still going at whatever speed they already are; so when you click down a gear and re-engage the clutch, you're immediately putting the engine back into the higher RPM range that your drivetrain and wheel is going at. in a manual car you'd feel it as engine braking..in a bike if severe enough, it'd cause your wheel to lock up..the remedy? below VV

to do so, as you downshift you pull your clutch in, click down a gear, then before you release the clutch, quickly rev the engine (doesn't need to be all out, just a quick flick of the wrist hence the term 'blip') This will decrease the chance of your rear locking up because you're revving your engine to an RPM range that is as close as possible to your actual drivetrain and wheel speed.

once you get good at that you can learn to downgear/blip/brake at the same time :D plus it has the added bonus of sounding leet :D

anyone feel free to correct me if I'm off, but im 99.99% sure

Ah fuck, you're right. There's a correlation between blipping and yellow socks cbrdave, according to a statistic that is 60% of the time, right everytime; the action of downshifting/blipping the throttle is made smoother with a pair of yellow socks on. though there has been no quantifiable evidence of this, my assdyno has proven so. I'm sure the same can be said of Mr. Logic.

i got one of these on mine, although i only paid $99 for mine but its identical to this, stickers went on the tool box though. it surprised me how nice it sounds, very deep compared to just about all other cbrs i've heard. not tinny at all.

crazylegs, though they look and sound alright, the actual quality and longevity of those cheapo chinese ones aren't highly rated...there was a thread on the old forum where someone actually took the packing out of a egay pipe and it was just absolute shit.rubbish.literally. the sound quality of the pipe i think you will see will soon deteriorate. quality pipes normally have a stainless steel wool kinda packing in it.not paper. :X

I also got a chinese carbon pipe. I agree with sound. My old stainless sounded like an F1 car, this is alot quieter and deeper.

i find it much smoother to do it without the clutch. you wont break it, when u can get it smooth/ seemless everytime you wont use ya clutch.


proamateur: bahhh just stuff some steel wool or something in there, its only cheap shit anyway. :)
