Title: £SRM?
Post by: Greybeard on 10.09. 2018 17:11
Ok, I'm ***** off with this engine and may feel better another day.

If I got my engine sorted by SRM I imagine I would ask for a crank regrind, main bearing and timing side bush, crank end feed mod and rebore. Hopefully, my steel oil pump could stay. How much would an engine overhaul at SRM cost me?

Might have to go back to work for a while or pick up a few tricks at the local gay bar. *whistle*

A rocker oil manifold and PRV unit cost me £95 from SRM. An engine rebuild must require double shifts at the gay bar...

What makes you think GB would not do well in the conventional Gigolo business? *roll*

It's only fun if we guess and then find out how wrong we were, so, for what you've named, including new shells, pistons, rings and gudgeons, my guess is 2975 GBP.

Is VAT charged on labor?

They charge it on whatever they can think of.
Make sure that you close the curtains at night or you will be getting a vat bill through the letter box for that as well.   *razz*

Are you quite sure you want to have the crank end feed conversion? IMHO it's really quite unnecessary. My well-used machines run the standard setup. Always have done, always will.

VAT on everything Richard, even on postage charges. What's more, they make the seller of anything act as unpaid and much put-upon tax collector as well, with big sanctions for not doing their job for them. I got very used to simple sales tax (like what we used to have in the UK when I were a boy) when I lived your side, even if it sometimes got added at the checkout and varied a bit between states.
I agree with Black Sheep on the main Q here. In about 50K miles my t/s main shows little wear.  Thou and three-quarters when last measured (a while back, at about 30K miles).
A mate with a Notrun has recently spent rather more than your estimate on a full job on a Commando that seized, but he had crank damage, rod damage, piston and bore damage, valve trouble and needed a camshaft too, and an oil pump and and and etc 'n all. Doesn't take long to ratchet up the £/€/$ on parts and then double it by getting a specialist to do all the work.
I'm currently fighting a minor piston seizure job on my own 650SS Notrun  . . . luckily minor by comparison as the bores honed good with no problem, so just new pistons, ex valves and a few ancillaries & odds and sods. Even so, still a few hundred of HMQ's devalued currency   . . . . and a bit of time.
Good Luck GB!

Thank you guys. I'm interested to hear opinions on the end-feed conversion.

Total waste of time & money on A 7's & 10's unless you are running them at 9000 + rpm with 15:1 pistons

Had my A10 SRM converted in 1984. Done many many miles since then including commuting. Would not want to go back to struggling with a bush, reaming and shims. Works perfectly. No crank end float to set, better oil feed to the big ends, no pressure drop when the bush wears.

It's not on my wish list, I think the conversion was developed for racing by Devimead.
The standard set up has been well proved for over sixty years.

God-knows how many thousands of A's did God knows how many miles, day in day out under often arduous conditions with crappy oil and all on the standard set up.
A couple of thousand summer miles gently ridden isn't going to over-tax it now.

Tend to agree.  Unless you're going nuts with performance and mileage, the standard set up with regular oil changes should be more than fine.
