Thread hijack alert to emphasise the o-ring issue.
Finally got round to pulling the carbs on my FZS1000 due to a slight low down misfire and a running a bit ‘wooly’ low down. They were very clean internally (almost perfect) but the original o-rings were not in good condition. The fuel valve o-rings were cracking and 2 snapped when trying to get them off. Main jet o-rings were rock hard and more like washers.
Back together today and instantly sounded better. Yet to test ride but for all the carb bike owners, consider doing these o-rings sooner rather than later. Thanks to unfazed for the sizes of replacement Viton type.
