"To The Store Manager,
I purchased my 2002 ZX9 from your showroom on the 15/07/2003 and have currently just completed just over 12000 kilometres. I have had my bike service by your mechanics at the scheduled maintenance period (1000, 6000, 12000)and have been pleased with their work. I however have had a problem with the clutch slipping when accelerating. This had only become evident on a ride that I was on two days before it was scheduled into your workshop for the 12000km service. I brought this up with I believe his name was Michael when booking my bike in and they removed and inspected the clutch plates.
They reported back to me that the clutch was almost worn out and was "just within specifications". This was going to be required to be replaced as soon as possible.
I am a mechanical service engineer and completed my trade at Qantas and have been in engineering for just over 8 years so I have a fair idea that although clutch plates being a "wear and tear" item should not wear out in 12000km. I am also a member of the Kawasaki sports riders club and posted a question to see what sought of service life people were getting out of their clutches being the same model, same year of bike. The answer was that people were on to the 14000-70000 km mark and had not replaced the clutch. With one of these members (36000kms) admitting that he was very prone to wheelies and burnouts with a total of 32 track days at eastern creek. Now for this sought of wear and tear that these clutches has received from various members it was a general consensus that for my clutch to be worn out at 12000km there was either a problem with the clutch (i.e. material) or that either the wrong oil had been used in the servicing or that it was not correctly adjusted. Now I tend to think that with your skilled mechanics that the wrong oil or incorrect adjustment would not of occurred.
I have however checked my invoices supplied at the end of the services and noticed that at the 6000km service that two lots of oil were used (qty 3.1 and also 3.3 of Motul:4T 5100 15W50) and at the 12000km service only 3.3 Motul 4T 3100 15w50 was used. Is there a difference in the oils used? (i.e.
Motul:4T 5100 15w50 - Motul:4T 3100 15w50) And why the 2nd charge of oil on the 6000km service?. I have the invoices for further clarification if required.
I upgraded my bike from a zzr250 to the zx9 and as you can imagine the power increase was quiet significant. It has taken me some time to get used to the power available of the bike and have been very reserved in using the throttle heavy handedly. I have been to 1 track day at eastern creek which was in "C" grade and have been on a handful of ride days. A majority of my time spent on the bike is whilst travelling to work which by no means can the bike be raced, wheelies or burnouts. I replaced the rear tyre at 11500kms after the middle section was flattened from the highway riding and not enough cornering. Most people on the Kawasaki site had a maximum tyre life of 8000kms out of the rear tyre. I am still running the original front tyre which still has more than enough life left in it for another 6000kms.
This suggests that the bike has not been "boy raced" and abused.
I find this disturbing that a major item could be worn out in 12000kms. It disturbs me even more to think what could wear out in 30000kms. I purchased this bike in good faith knowing that the Kawasaki zx9 has a great name and not many people can fault the zx9 for what it is. I purchased it thinking that i would have many years of faultless riding as long as regularly maintained and serviced. I ask that this matter be investigated and rectified as my bike is my mode of transport and don't feel that this is a normal wear and tear but more like a warranty issue. My bike will not be ridden anymore until it is required to be brought into the workshop.
I can bring the bike in anytime when most convenient for you to be fixed, contact me with time and date. Below I have included my details as per your invoices. Please don't hesitate to contact me if you require any additional information. I look forward to working this out.
So i will wait n see what they come up with.
