Definitely lasted longer than that Knut...
Oil pressure I assume is good ? Oil pressure light is off ? How long did it take for the noise to clear up ? Maybe oil too thick for pumping well ? It was cold out you said. Maybe you can hear more noise because of the quieter Thiels mufflers?
Yes oil light off etc.
Yes it was cold, so thick oil is a possibility.
But so is thin oil. The factory use Silkoline / Fuchs and I have had bad experiences with their oil breaking down before. I thought my BSA R3 engine was shot cos the oil light was on, long-story-short the Silkolene oil had lost its viscosity, after one weekend on the track in hot weather. New oil, problem solved. So it is not beyond all possibility that similar has happened in mine, after all we had a very hot summer here and I had it on the track in hot temps.
The Thiel pipes are NOT that quiet Tony, far from it! I had the noise issue with the old pipes.
I started it up today with the Theil pipes and got it good and warm and probed around with my electronic stethoscope, to try and ID the noise... but guess what... no noise (above the usual clatter that is)!
So, my current thinking it was just the hydraulic tappets. I’ll be getting it serviced, so new oil, before getting it out on the road again and will, of course, be keeping my ears open !
Sorry, without a video this simply can't be believed.
We'll need to hear it, and see it.
Talk to Ollie about his rocker arms. They are a great improvement to the Norton ones. There is a known issue with the OEM ones sticking. You could pull your cover and do a quick check. Couple bolts. I have a manual to help. Definitely pull them out not just a peak under the cover.
Hello Richard , Does Ollie do whole new rocker arm plus bushings plus new shafts ? Does anything get reused like the adjusters and lock nuts ? Nice.
Do they make it faster...?
