- I scored very low on the autie test. I’m cheerful, happy, confident, like meeting new people, chatty and largely sociable. What the fuck am I doing on this forum?

That’s a proper mess. £950 sounds a lot but you’ll be enjoying the bike long after you’ve forgotten the money.

Re: Stroppy Old Tart, or the story of a Triumph Bonneville
Indeed. It'd be a bit cheaper to get a new head I think, but it'd never seem right to me. I don't like changing big bits if I can avoid it & by getting it all fixed it should last a good few years.brandersnatch wrote: ↑Sat Nov 21, 2020 8:11 pm That’s a proper mess. £950 sounds a lot but you’ll be enjoying the bike long after you’ve forgotten the money.

Further update for the day, they've fitted new exhaust valve seats as when recut they were too deep. That wasn't an expected bit, but not a great surprise on 44 year old head.

Re: Stroppy Old Tart, or the story of a Triumph Bonneville
It's nice to see an engineering so taking on something like this, most would either make a right pigs ear of it because as a big job it gets given to the apprentice to save on hours.
Looks like they know what they're doing, at least. Hopefully that new material won't fail in the same way again.

Re: Stroppy Old Tart, or the story of a Triumph Bonneville
They've been doing it for years, so I hope they do. It's a couple of old blokes in a workshop from what I can tell & they'll do anything.

Re: Stroppy Old Tart, or the story of a Triumph Bonneville
I had to buy a new head for mine after an 'engineering company' skimmed it on the piss. Was the easier and probably, the only solution.
