Greetings,

Recently, I encountered an issue with my FZS 600 (98'). Despite investing a significant amount of time exploring and following recommendations from my mechanics, I find myself questioning several aspects of the incident.

In brief, while riding, my bike suddenly experienced a loss of power, forcing me to pull over. Subsequently, the bike shut off, and all attempts to restart it failed. Upon inspection, I observed a substantial fuel leak originating from the air filter box and the drain hose. As a novice rider who had recently embarked on this journey, I was ill-prepared for such an unforeseen circumstance, especially considering that I had recently undertaken comprehensive maintenance, including carburetor cleaning and general servicing. As I waited for assistance to arrive and transport me to the mechanic, the fuel continued to overflow, mixing with oil, saturating the spark plugs, and ultimately depleting the fuel tank entirely.

Upon assessment, my mechanic drained the system, replaced the oil, oil filter, and spark plugs. According to their diagnosis, the malfunction stemmed from a faulty fuel pump, specifically a component responsible for regulating pressure. To elaborate in my own words, it seems that the mechanism within the fuel pump designed to control pressure, thus dictating when the pump should cease operation upon reaching maximum pressure, had become defective. Consequently, the pump continued to operate beyond its intended limits, resulting in the fuel overflow. The absence of a relay exacerbates the issue, as it could have preemptively prevented such a scenario.

Has anyone experienced a similar situation, and can you confirm the validity of my mechanic's explanation? Additionally, my mechanic suggested the installation of a vacuum valve as an additional safeguard against future occurrences.

Regarding the replacement of the fuel pump, what factors should I consider to ensure I acquire a reliable one, given the prevalence of substandard options on the market?

Thank you for your attention and assistance.

Best regards,
AJ

The time has come where my rear brake is now longer functioning as it should.  To my knowledge it's never needed any remedial work so it's time to have it serviced.
Lacking the skills to do it myself I'm entrusting my local garage with it.  The said it would be cheaper to get a kit myself.


Question is....do I need the full kit with bleed nipple etc... or just a kit with the seals?  I'm going to have the pistons changed too.
Been advised to avoid Ebay ones as they aren't the best but I'll be guided by yourselves on that front?


And advice on kits would be most welcome.  And pads whilst I'm there.....

Quick question, what chain and sprocket sets do you all use/favour for a Gen 1 thou??

Hello

I have an issue, I have damaged the sticker???? chassis identifier.  First I sprayed over it, then tried wiping the spray off and the whole thing just wiped clean, no text left what so ever.

How do I put a new one on?  Where do I get them from?

Any help will be great.

Thanks

I bought my '03 from the 2nd owner. He actually bought it from a shop. The first unknown owner installed a Yosh slip on. I've put almost 20,000 miles on the bike and it has always run perfect. Fires up instantly, idles perfect, butter smooth all the way up to redline. No popping or anything. Probably the best running bike I've ever owned.


Does it sound like it was jetted for the pipe? I ask because I'm going to call and see if Dale at Holeshot still has a set of headers for it and I'm not sure if I'm going to have to address the carbs. I know he runs a stage one jet kit with slip ons and full exhausts so if mine is already jetted I should be good to go. And yes it has the stock airbox.


What do yall think?
