2nd Gen Hayabusa
Last Updated : 13 November 2011
There are heaps of problems
that may occur to any motorcycle not just the Hayabusa. Many problems
are the result of poor maintenance and/or performance related modifications.
However there are those that occur from wear and tear. Here's a list and some successful problems/solutions tried by various owners and
results good or otherwise of their solutions!
Index of Problems
Inaccurate Speedo reading
Spot and Fog lights
Oxygen Sensor Issues
Solve the Grabby
Clutch Prob if you have one
High altitude stuttering.
FI light and rough running.
Clutch Fluid leaking
Clunk noise on standing start.
How to fix the vibey screen (From Sept 1999 Archives)
Gear changing or gearbox problems.
Excessive Tyre/Tire wear.
Engine running and electrical problems.
After market pipes/exhausts
As with all bikes, there is a high possibility that the fitting of aftermarket pipes will effect performance. This was particularly true when most bikes still had Carbs.
Bikes in particular those like the Hayabusa
are extreme performance machines.
Hence engine tuning to meeting all the planets different pollution regulation you'd expect the tuning of the bike to be pretty much complicated. Changing any one of the components eg. exhausts which play a large part in the performance equation you'd expect certain problems to occur.
Some of the common problems include :
Spot and Fog
Some include whining from the fuel tank, fuel pump, brake buzzes etc... The solutions to these are not easy to determine as some can be relative in nature and dependent on modifications done to your bike. Eg. You may be more sensitive to fuel smells or hearing. The best solution to these problems to to contact your servicing mechanic. If you're servicing mechanic does not acknowledge the noise get them to compare your bike with another this will usually enable them to tell the difference. If not I guess the only solution would be to try another mechanic or specialist outfit.
If you have any and know the solutions pls email them ! - Thanks
- Some 2001 riders have reported that the
bike has trouble re-starting after hot running.

Stuttering problems 3.
Clutch fluid leaking.
The screen is secured to the fairing by 2 screws near the mirror. Taking the securing nut out was easy, using the standard toolkit but the rubber bit is another story. The rubber bit is NOT a washer. It's a plastic tube that has a lump in the middle. The holding nut is moulded inside this tube. You must pull out the tube washer before taking the screen off, its about 1.5 cm long. When the nut is tightened the rubber compresses hence tightening the screen.
Anyway, once the tube washer is taken out, the screen can be pulled off by sitting on the seat and pulling it towards you. Once out of the fairing you will see the recessed edges of the screen that slots into the fairing. I used electrical tape to over ALL the edges (at least 2 layers). Don't use too much or you'll be able to see the tape when the screen is inserted back and the fit will be really tight and the securing nut will not be able to be screwed back in. Make sure ALL the edges have been covered or the screen will vibrate in a different place.
Once completed insert the screen back into the fairing aligning the securing holes. The tube washer can then be inserted back in. You may find this difficult because when you try to push the tube in the lump expands making the tube wider hence too big. The secret is to loosely put the bolt into the tube and nut place it into the fairing hole and with the hex-tool from the top and push the tube in. If aligned correctly the tube goes in without any effort. Why, put placing the bolt in and pushing from the top expands the tube, making it thinner, the lump in the middle flattens out ! Tighten the screen and go for a test spin. hopefully if you've taped the right areas on the screen the vibration should disappear. Well, it worked for me!
The only reports I've heard of Hayabusa gearbox especially breaking is due to heavy modification to the gearbox itself. Personally - I can't see the point of changing the gear ratios (actual cog) as that is one one of the reasons it can go as fast as it does.
Excessive tire/tyre wear ?
Engine running and electrical problems ?
As motorcycle electrics gets more advanced so too the number of problems that can occur. However over the years thanks to car developments it is unlikely that the ECU that controls a motorcycle's engine, eg. spark plugs, fuel injection and so forth would the cause. So if you encounter strange problems like miss-fires, cut outs and so forth it is usually caused by something else.
Assuming your bike has remained in standard trim here's a quick guide to diagnose or fix what could be electrical problems. Remember to always check the obvious especially on older models.
Miss-firing can be caused by kinked fuel hoses. (I should know mine had one) When you do check the hoses it may not look it but consider replacing various hoses anyway. Consider replacing the spark plugs and leads as a preventative measure. So check that operation of the engine kill switch it could just be a faulty or corroded contact here. (I should know I had a similar problem - how embarrassing). Spray the internals with WD40 or similar.
Another thing to consider is the battery. After 3 years it will deteriorate, after 4 - well I consider replacement. Sure not essential by could be the cause of your problems. Check the battery contacts and also the various grounding cables while your there.
Other obvious things to check is the fuse box! Sure you may not have ridden in the rain or left it outside but because it is a dry location you may find that ants or other insects have decided to call it home.
If you don't ride often or ride short distances the fuel in you tank may go off - it's not an urban myth. Drain the tank and start again. The instructions are in the manual. I've had an email this year saying that they had to replace the fuel injectors. Deterioration caused by fuel... Then again modern petrol has cleaning additives...
So give things try if you think you have running or electrical problems.
