Well i finally got my redbird back on the road and it was handling beautifully, a joy to ride, really felt nimble and quick to turn, leaned lovely.
I heard a knocking noise..
Which is only there when it comes on power about 3.5 - 4,000 rpm
Seems to be coming from mid/top end, rather than big end knocking.
Its present regardless of clutch and only under load.
Whipped the fairings off again and rechecked the balance shafts and the cam chain tensioner (fitted new by previous owner and basically zero milage.
So looks like a rebuild.
This sucks big time, i have sorted soo many issues with this recently acquired machine I've hardly managed to ride it and just as thought I'd finally sorted EVERYTHING "boooom" first good test ride and this happens.
Just prior to this knocking, i heard a loud squealing noise which changed pitch. It went above 2k rpm and was only present for a short time, which led me to check the balance shafts. But the balance shafts was a totally different noise. This noise was LOUD and squealy.
Maybe the prelude to what sounds like a 'small end' failure?
Anyone had an experience similar to this?
Thank god i didn't sell the Triumph (ST955i) Good old dependable Triumph, on 66,000 miles and still pulls as strongly as the day it was built. I was totally prepared to sell it as soon as this beautiful sexy red bird came along 😁
