550 F2 started!
mickwinf:
could it be the starter clutch mechanism?
Laverdaroo:
OK, so under investsigation yet again, the starter is doing the 'parp' as I hold it in my hand and power up so new end caps sorted and a fix on the way. Under inspection yesterday I saw and heard no issue but session 2 has thrown up the full fault and I can replicate it so 99.9%, that's the offending issue.

BUT............... and you knew there was going to be a but, this brings me to a point brought up whilst talking to a fellow miserable, sarcastic northerner this evening who righty says or questioned. why does it do the 'parp' when you swich the engine off, it shouldn't be spinning?
Technically, as soon as you've let go of the start button, the starter isn't powered up and stops spinning. Other wise if it kept going it would be the same speed as the engine and would probably blow up at 9k on the tacho with yer chin on the tank?.
So it obviously makes the 'parp' as the motor is spinning up to speed, ok, and when the motor is turned off, presumably at a similar speed as it slows?
If I poke my finger into the hole onto the idler gear I can turn it only one way but not the other as its against the turn of the internals indicating it's maybe the balbearings in the cush assembly in the drum, one on the wonk or something and its taking up the slack ....................Bas*ard!!
I'll take the pan off tomorrow night and poke about and see if anything is visible but also we discussed there being a thread on folk getting to all the internals somehow through the pan......anyone read/seen anything or indeed carried out the operation? It will be a pig I should think but its game on and needs doing so before I fire the parts cannon, just checking to see if anybody has any experience.
thanks all, shit happen's I'll sort it ;D

The starter clutch can make some clattering if worn. Did you replace all the parts in the starter clutch and did you check the cog surface ?
Trigger:
There is a picture of a bad ring gear cog half way down this page >> http://www.sohc.co.uk/index.php/topic,20419.120.html
Start striping and check every part as you remove and double check on reassembly ;)
Laverdaroo:
Yes and yes, new rubbers the lot hence why I might have buggered up putting in the nall bearings. I didn't think so and thought it was all good, but it fits the symptoms as a possible so I need to look and trying not to split the cases as I'm sure you can understand ;)
