Yeah the aftermarket pipe that I put on mine totally changed the power delivery. Had nothing below about 7,000rpm, but once you hit that, the power KICKED in - with a steel-toed boot to the gut. Front wheel got very light very quickly, and the bike shot forward. like it had a rocket stuck up its arse.
I found the stock pipe far more convenient for city work, but on open roads the aftermarket pipe was awesome.
RZs are awesome little things. Stick on some Bridgestones and decent shocks, and they can corner like theyāre on rails. Very reliable machines too.

Haha, yes, this pipe is even worseā¦ while Iām racking up 8,000-8,500rpm I get passed by scooters but then the power kicks in and it whups everything including performance cars and scooter punks up to ~110km/h*. I have a scooter for light shoppingā¦ a car for haulingā¦ and the RZX is ALL FUN Iām getting excited nowā¦ I think I need to go out for a ride and/or cold shower.
of course I advocate responsible riding at all times
I love my NSR. Yes, itās 13 years old and covered in Kymco stickers, but itās my first bike (scooters donāt count) and iāve had some great fun in the 11 months Iāve owned it. Itās taken me all over north and central Taiwan, including a slightly deranged ride over the central highway from hualien to Fuxing. and onto Wuling farm. I bought it all stock and itās still all stock, mainly because I canāt find someone to fix it properly.
Itās been reasonably reliable, but not without problems. It stutters badly in first and second between 6 and 7 thousand, and wonāt make max revs before the power drops off, which means Iām not getting full power out of it, I think. Iāve had a rebuild, which helped a little, but if anyone knows an NSR mechanic, or good tuning shop, iād be interested.
Anyone know the fines for running them non-stock? Every NSR I see in Taipei seems modified in some way, canāt believe the police let them all go.
i know a shop in taichungā¦ they know heaps about NSRsā¦ but theyāre definately not on the cheap side eitherā¦
the NSRs iāve test ridden before all seemed goodā¦ more power than i expected, but even more peaky than my hornet - which is something i wouldnāt want on my day-to-day commute~ the hornetās engine is about as peaky as i wanna get for normal street riding, though itās great for thrashingā¦ nothing like flying through the mountains, keeping it between 12-16k all the way
i had an RZ 300? 350? for a while many (many) years ago and can vouch for their bulletproof engines and the fun factor, but man, they flex and squirm. you probably should keep the stock broad power pipe, rather than any short peaky power pipe.
thereās no need to go any bigger sizes on the tires either, itād be a waste of money to change rims. the frame is limiting you there. but on the back wheel, who really cares?

Really sticky rubber just shows you how flexible the RZ* frame is. The NSR otoh is very front biased with itās weight distribution, and has a very stiff chassis. Since thereās not much weight on the rear tire, it wants the stickiest rubber you can squeeze onto the rim.
As to expansion chambers, well, it depends what the owner is going to use it for. No aftermarket exhaust is going to provide the midrange the stocker does. Having said that, the stocker is designed to show a torque spike at around 4k to make the bike feel punchier than it is. There used to be some very pipes available with much larger volume than the average, which showed good useable torque from about 4k, and then the real meat of the powerband at about 7k. The typical skinny low-volume pipe is a 7k rpm light-switch. Nothing below there. Thatās fun on the open road but a real drag in traffic.
It also possible to port the RZ* for midrange torque, which works well with the stock exhaust.

I found after climbing the hill to my house everday that my RZ was much more user friendly in day to day commuting with the stock pipe. I just moved, and discovered my speed pipe for my old bike down in the basement. Kicks in around 7k and maxes about 10.5. Free to good home. She would hit 160kph (or bury the 180kph speedo) with this bad boy hooked up to it. Also have muffler.
Off topic, but, my Ninja is finally home, with fresh bodywork from Japanā¦ :discodance:
Cāmon, itās a small-bore, two-stroke crotch-rocket. No-one expects to get 100,000km from a piston, especially when used the way they beg to be used! The OEM pistons on both bikes are very good actually. The aftermarket (oversize) pistons generally available are just garbage. With my NSR I ended up having to use a Wi$eco forged piston which a vendor in Taipei had ordered $pecially.
Neither bike is very heavy on oil when you consider their fuel consumption. Maybe yours had the oil pump jacked right up. A lot of local mechanics think (warning!) that they will improve something by increasing the amount of oil injection.
Stick on some Bridgestones and decent shocks, and they can corner like theyāre on rails. Very reliable machines too.
