FZS600 Fazer / Grinding noise/feeling around 6000rpm
« on: 06 May 2013, 11:11:55 pm »
Hi guys,
I have some strange behaviour that I'm not sure is normal.
When I pull through the revs and gears, it feels like the engine (I assume) starts grinding at around 6000rpm give or take. I can feel it through the handlebars and it tends to go after about 7000rpm or when I push it way up into the power band its fine too. This occurs worst when im going about 60 mph and keeping the revs in the trouble zone.
I also found that if I potter along at just over 5000rpm it feels really smooth, no vibration or grinding and almost no negative engine sensation at all.
I have a new chain and sprockets (600 miles ago) and a new oil filter and oil change then too (when I bought the bike). In an attempt to improve it, I tightened my chain very slightly today and lubed it and realigned my back wheel because I notcied that the adjustments on the chain tensioner didnt completely match and managed to get them to be almost the same now.
I took the bike out 2 hours after making the adjustments to allow the lube to dry a bit and I feel like it has improved and the rpm range of grinding is narrower now, but still centered on 6k. I will check the engine oil level in the morning just to make sure too.
I have tried to search for this but havent seen anything that exactly matches what I feel. As an engineer, it makes me cringe because i'm running all kinds of imagination adventures where I visualise too big metal plates grinding swarf into my gearbox haha
Is this well known to you? Any tips?
Many thanks!
James
