Hey all, has anyone found or used replacement spark advancer springs?

Not sure what the spring rate is supposed to be but mine are not returning the little arms very fast. It's almost a damped return, and one of them was definitely slower than the other. I twisted the spring a bit and it looks to return at the same rate as the other, but it now doesn't look very straight.

Is it supposed to be a "snappy" return? Or maybe the grease I've used is to thick?

They can hang a it if lubrication is thicker than ideal.

You could use silicone "plumbing" supplied grease as it will be OK at both extremes of temperature range on the spindle.

Check live timing once running with a strobe to see if it settles down to minimum ok.

Yeah good shout. Its relatively easy to pull out if thngs arent working as they should. Got a long way to go before I check live timing though!

Hey all, picked up a set of Vesrah gaskets for my engine rebuild.

Can I just confirm that I don't need to use Hondabond in this situation?

Hondabond is only used for sticking top and bottom crank cases together as they are machined surfaces and use no gasket. Only the lightest, lightest smear of Hondabond is needed though. All gaskets are fitted dry or with a very light smear of grease (ie, clutch casing, sump pan etc etc) we fit them dry though. No grease on head gasket though.

Thanks Julie. One more thing, I purchased Hondabond HT, is this OK? Or should I be using Hondabond 4?

Either is fine to use.

Having split my 400 crank case 3 times I became more skilled at applying a nice thin layer of Hondabond each time.
Following advice from Julie the secret appears to be - don't squeeze  it onto the crankcase directly out of the tube - obviously apply to the inverted upper case only
I wore surgical type gloves - applied a small amount less than half an inch directly onto my fore finger then spread it onto the crankcase starting at one end repeating once the finger full had spread as far as it could. Repeat until all applied. I actually put the Hondabond on my left  finger then dipped my right fore finger and spread it nice and thinly.I then removed any excess that had spilled over the inside edges. It spreads so thin I found using this method. Sorry if I'm being over descriptive & stating the obvious.

Then assembled making sure I bolted up in correct sequence as per manual keeping my eye on the primary drive assembly etc.

It's all great advice Ted. Id much rather be told how to do something 10times rather than not know and muck it up.

I've lost the thrust washer that sits on the outside of the kickstarter shaft - any idea what thickness this one is supposed to be? It's listed as an 18mm Koyo washer.

It's 1mm thick, check the clutch case as they sometimes stick to the inside of the case.

Cheers.

I did take a photo when I was stripping down the engine and noted back then it was missing. Didn't notice anything in the case though at the time.
