Regulator/Rectifier fitting

[smudge]

How easy or otherwise is it to fit a replacement regulator/rectifier to a '92 CB400 Superfour?
Is it just a bolt-on clip fitment?

Is Wemoto the best place to source one or would Dave Silvers be a better option?
Also going to replace the battery at the same time, any suggestions as to best/most cost effective type?
Advice welcome...

It's a piece of cake; behind the nearside panel below the seat, two bolts hold it (and an earth lead) to the frame. There's a multiplug connector to disconnect, then "reassembly is the reverse of removal" as the saying goes!

I bough mine off ebay:

£40 inc shipping IIRC. It was the cheapest I could find anywhere. If the quality of the potting and finish is anything to go by, it should be fine!

HTH.

has your battery failed?

if not then i would just keep it,unless it has suffered damage when your reg/rec has packed up!!!!

It's a mate's bike. It's not been run for 5 years when the regulator packed up. Silly fella has left it in his garage with the battery still on. Not on Optimate, so I'm guessing it's completely dead by now! Brakes are not seized on, so I'm guessing new reg and battery, fresh fuel and she should burst into life. A quick service and should be OK? Anything else to look out for? I can't imagine the engine would seize up just from nor being run?

If the engine hasn't turned over in all that time, I would suggest putting some fresh oil in first; then whip the plugs out and crank the engine over by hand so that the fresh oil is fully circulated, so that engine wear is minimised during starting.

If hand cranking is difficult, knock the bike into top gear and walk it around for a bit with the clutch out to turn the engine.

Failing that, you could use the starter motor but you'll be using up precious amp hours of juice!

Excuse my ignorance, but how do you turn the engine by hand?
Honestly didn't know you could push a bike when not started in top gear either. You must think I'm a complete dipstick!

As always big thanks for the tips - might be back for some more help yet!

how do you turn the engine by hand?

Er, I'm not sure! That's why I suggested another method

On a car it's easy; you get a socket on the crankshaft pulley bolt and turn that with a bar or ratchet or whatever. Bikes don't have pulleys, so I'd guess that the only suitable method is to turn the rear wheel when the bike's in gear. Top gear is easiest as a large movement at the rear wheel translates into a small movement at the flywheel (high road speed = low rpms). Conversely, first gear is hardest (low road speed = high rpms).

HTH.

there should be on one side of the engine a timing inspection cover,once you remove the cover there should be a nut which you can fit a suitable socket to.you will be able to turn the engine whilst turning this nut.

it's actual purpose is for setting the camshafts to certain points for doing the valve clearances.....alternatively you can use a stand and put the bike in a high gear and rotate the rear wheel.

Ta boys, I'll put it on a paddock stand and give it a whirl!
