Engine rebuild Parts list
Athame57:
I guess it depends on what might be wrong. I've just spent £450.oo on parts and £700 for labour, price agreed beforehand, presently my bike is still in the garage. I was advised to get the rebuild because of leaking gaskets and some seals. I opted to get the cam chain, it's 'horseshoe' and tensioner blades complete changed while things are open and a broken piston ring was also found. Nothing else that really matters has come up. Mine is a 1978 CB400F with 40,000 on the clock, the last 12,000 were gentle ones with me.

How were the bores?
McCabe-Thiele (Ted):
My figure is £1200 is for parts then fitting them yourself - obviously having a rebore done by a specialist is included.
Mileage although a factor is not the whole cause. An engine that has stood for long periods in a shed or similar will deteriorate. Internal corrosion from condensation & old engine oil sticking clutch plates etc etc.
My parts from memory were Rebore & Pistons by Trigger, two Helicoils and machining for the tensioner bolt upgrade. I had to replace all the crank bearings, a couple of gearbox bearings, Primary drive rubbers, PD bearings & PD chain.All engine gaskets & seals plus camchain, one used valve, valve stem seals. Full Gasket Set plus some gaskets not included in my set. Oil filter & new sump plug. Hondabond & Locktite tubes. Clutch friction plates & clutch drive rubbers. Some replacement engine casing bolts plus zinc plating of many bolts. Replacement side casing fasteners. My bike came with new tensioner blade and some new cover gaskets. Oil pick up pipe tubing, new circlips as required I will have missed a few bits off this list like some replacement engine dowels.
Bryanj:
Have you priced a rebore recently, the last four sets of 500 i did did not clean at 0.25 as the bores were "barelled" had to go to 0.5
