ERM... Actually I have stellar scores on the surveys, and every year students tell me that my classes are the best ones they’ve ever taken.

Can anyone identify these pipes? They came with the bike when I bought it, and I haven't seen any like them in my quest for less obnoxious exhaust. I'm looking for either the manufacturer, or even what this style is called.



Around here we call those "open headers" and lol you weren't kidding when you said your bike was ridiculously loud. You probably won't find a manufacturer because those aren't something that is manufactured as an exhaust system -- it's just the pipes that would normally lead to a muffler but with the muffler and everything south of it lopped off. It's a resonant open-ended tube connected directly to the exhaust port. It is impossible to make a louder exhaust.

What state are you in? In any state with a noise limit that's going to be illegal.

I ended up buying a Nighthawk 750 with dry rotted tires. I want to order new tires ASAP. I was thinking of getting radial Michelin Pilot tires for it. Is it okay to get radial front and back tires for the bike when they had OEM Bias tires?

I prefer the feel of radial tires and I don't mind spending the extra money on them.

Someone got you a obnoxiously racist av.
They're some variant of straight shots / 'big-radius'. Sagebrush is wrong, there are a -lot- of manufactured versions, just GIS 'harley short pipes' or something similar.

Not only are they going to be noisy as poo poo but inadequate exhaust length = inadequate scavenging means you're losing a lot of power, especially on the low end. Lord only knows if it's jetted and mapped for them.

Ah yeah, short pipes seems to be the keyword for these. I'm sure they are illegal, but I though most aftermarket exhaust was technically illegal, either because of noise or emissions. Either way, these are coming off asap.

People seriously manufacture open headers and sell them as anything other than headers?? When if you want the same effect you can, you know, just leave the headers open, or hacksaw off your muffler in 10 minutes?

I guess I'm not surprised, in retrospect.

A lot of them are, but it's usually not quite as blatant as those things. It's completely possible to make an aftermarket exhaust that's nearly as quiet as the stock one at idle and still meets the noise regulations at other speeds but flows more gas. The legal problems come more from a "this is an unapproved part of the emissions system, only approved parts are allowed" regulation than anything else.

I dunno about emissions. I don't think the US standards even require bikes to have catalytic converters yet -- even in California, the most restrictive state in the country, you don't have to have the emissions tested.

Get ya some Pilot Power Road 2, 3, or 4s. They're solid all-around tires, and they'll be nice on your Nighthawk. There's no reason not to get radial tires unless you like it when your tires disassemble themselves at speed.

According to this, your tire sizes are:

I have a semi-related question. My 919 has honda's H.I.S.S. immobiliser key system. I want another key because the bike only came with one and it's so knackered that every time I open the fuel flap or seat lock I feel like I'm going to break the thing. Is there some way of getting around the immobiliser system so I can just use a plain normal key, or something? This issue is important enough for me to complain about and look for a fix for, but not important enough to lay down $300 for another HISS key.

Can you remove the immobilizer, or is it far too ingrained into the bike to even consider doing that?

From what I can tell it works like a car immo. Transponder in the key triggers an antenna around the ignition barrel. This sends the key code signal to either an immo unit, which signals the ecu, or to the ecu itself. I'm not sure which it is but the immo unit and ecu will both be coded to the key so just bypassing the immo module wouldn't make a difference, I don't think. I'm kind of hoping that there's some kind of factory disabling system or something.

I have a sport bike question.

I am not a knee-dragger by any means. I may have a slight need for speed, but I'm old and kind of a chicken, so I'm not looking to do corners at 100mph.

However, I'm wondering if there's something I can do to improve my posture/position on my bike. I've seen people ride where their toes are pointed at the ground, and I don't know if that's just a personal preference thing, or a legit real thing that's done for a good reason. When I'm sitting in a tuck, the balls of my feet are on the pegs, my knees are up around the tank somewhat high, and my crotch is not pushed right up against the tank. I find that I have a lot better "suspension" that way by using my knees and back to post very slightly. On the other hand, my knees get sore pretty quick like that, and I feel like maybe I could adjust my pegs in such a way as to make it easier/more comfortable.

The other thing I notice is that I have to move my legs a little if I want to shift or brake, if I've been crusing in a tuck for a while. Is that pretty normal, or should I look into moving my pegs?

Someone suggested I look into rearsets, but then someone else said that was for knee-draggers only. Help me, moto-friends.

You are doing the right things. Don't let weight onto your wrists, especially under braking. Also get some grippy things on the sides of your tank, it makes riding a sportbike properly a million times easier because your legs actually grip the tank instead of sliding forward uselessly. Another good tip is to try keep your torso parallel to the bike, instead of having just your shoulders or just your arse dangling off awkwardly. If your bike allows it, hooking your outermost elbow on the tank is helpful, sometimes. I try to keep most of my weight on my feet/legs instead of my arse when I'm going around corners. In a similar vein, I've found that deliberately moving my inner foot so that the toe is pointing downward at the tip of the peg, and my ankle/heel are up by the heel guard is helpful for posture. Along with this, I move my outer foot forward so my heel is hooked on the peg, this seems to help drive my outer knee hard into the tank and lets me hang a good part of my weight off that leg, with the inner leg supporting the rest.

A lot of this stuff is personal and subjective and altered/limited by the shape of the bike, the riding gear, the proportions of the rider and so on.

Most people can't ride for poo poo so don't take your cues from random cunts you see in the street, chances are they are utterly useless and having a literbike does not make them a good rider, or even an average rider.

Rearsets will help you if you find you're having to lift your knees too much to grip the tank effectively. Your feet to shins angle should be roughly 90 degrees. You can customise a bike to the nth degree to fit you perfectly but you need to master fundamentals first before any of it really matters.

I say all of this as someone who thinks of themselves as having only moderate ability.

Cut a key up and tape the chip to the cylinder? Tape the chip to your burly key? I honestly have no clue. These things can't be too terribly smart. My experience was that the key was fine until my gas cap hosed me. Then came pliers, hammers, and blocks of wood so I could get a blank cut to replace my OE keys as those poor bastards had been work hardened from constant bending.

Mostly. Most sport bikes have a bar diameter of 7/8", including the R1/R6. You may need to modify inside the throttle housing (grinding off random plastic bits) if the cam is significantly bigger than the stock one.

Also there are 2 variations of the R6 throttle tube. Up to 05 was 1/5 turn (36.9 mm), 06 and up are 1/6 (40.76mm).

In their defence, an immobiliser system that's easily bypassed/removed is not a particularly useful immobiliser system.

I've seen remote start setups (on cars) where they will take a spare key and hide it near the immobilizer antenna, usually under the steering column cover. If there is a good place to hide your old key then you should be able to do the same thing. Shove it in the hiding spot, get a regular key cut and see what happens.

This is an idea that's worth investigating. I've also considered just carrying two keys and using the plain one to open the gas cap and seat.

Hey FedEx, how dare you deliver something before your "delivered by" time.
It's a pretty safe bet that enough UV can gently caress pretty much anything up. I'd guess that picking up water and letting air bubbles in degrades performance faster than letting some sun hit it though.

I've had those clear reservoirs get all chalky and start to disintegrate from being in the sun too. I'm guessing it wouldn't be too big of a deal for a bike that lives indoors or one that stays in the PNW where there is no sun but it's always sunny here and my bike is always in it so whatever is UV sensitive gets disintegrated quickly. I even have to change those sweat band things every year or so when they fade and the elastic fails.

So I got a used cbr250 a few months ago, only had 1800km on the clock. Pretty much every time on startup with a cold engine the clutch tends to be grabby and squeek a bit (when I'm letting go of the lever), but only in first gear. Once the engine warms up (literally 2-3 mins) the problem disappears completely. Is this anything I should be worried about? Might a general service/oil change help? The oil level and clearness seem ok to me.
