Oh no! Death Rattle!

Get in, result!!!!!!!

Well done dude Im glad to hear it. You can now join my club,welcome to the we got away with it club.
Or the CCT Unwound No Trouble club (Ill not abbreviate that one ) C@*T club

I have to say that as you already have it stripped that far, you might just as well pull the head off to make sure.
It'll cost you a head gasket, but then it'll save you a compression test....

Well - Tonymon, you were right, AGAIN! Popped the head off and I think I've got away with it!
WooHOOOO
No sign of the valves touching the piston at all - no marks in the carbon at least.
No evidence of metal mashing anywhere in fact.
Need to look closer at the cam sprockets & chain but, manual CCt's, new head gasket and away we go!

Rop,rop,roppity rop!

A/G, that all certainly sounds good I agree but before you re-fit the cylinder head I would suggest turning it upside down and filling it with petrol just to double check the valves are sealing.

Is rop, rop, roppity rop rhyming slang for what Tony suggested ?

Hah! Showing my age now - that's the noise Ogri's bike used to make in bike magazine when I were a lad....

Jazz, I'm already a fully paid up member of your club - lots of people use the acronym as my name

and Chris thanx for the suggestion, that's tonight's project along with wiring a gear indicator onto the instrument panel. Sad I know, but so used to riding inline fours I keep forgetting to change up...

The Acumen was another fleabay bargain. Along with the genuine head gasket winging it's way in the post.
Just need the sun to hang around a bit longer

when programming the gear indicator the better you hold it at 2000rpm the more accurate it will be

[tony.mon]

Result indeed, it's not often you get the noise but not the expense......

Re the Acumen, I posted a wiring post in the Workshop Knowledgebase to save you trying to reinvent the wheel.
Mine is the one with the voltmeter built in, but should be the same.

[Arfur_Guiness]

Hmmm 2000rpm - in top, on a paddock stand?
Sounds a bit daunting. Anyone tried programming on a nice bit of dual carriageway instead?

Gaskets arrived today. Shame I'm so knackered after work - had one of those days today and have got a customer inspection tomorrow.
Think I might just throw a sickie and fix the Storm. Especially if the postie delivers the new ROAS CCTs....

OOer. Perhaps I should have read this first?

I've made all my connections at the back of the instrument cluster by popping out the brass blades in the multipin blocks and soldering the Acumen wires on, piggy-back stylee.
Figured all the requisite supplies were there to hand and it keeps the wiring runs short, reducing the chance of noise interference.
Obviously, as the front pot is decapitated at the mo, I can't program or test the set-up but with the ignition on it displays zero.
Do you think this will work? (Mine doesn't have the voltmeter - just the GI.)

[cliveyandrews]

Where you at, Arfur?

Hi Tonymon
Recognise your name - kudos to you.
I'm on the sunny south coast - not far from Bournemouth, out in the sticks where the roads call me to go and play!

Not too far from me then - I'm in Gosport - I was in Bournemouth last Thursday picking up a trailer actually....

[Arfur_Guiness]

hey clive. You're a Hampshire Hog then? I'm on the Dorchester side of Bournemouth so not quite so close but do like to ride the New Forest now and then.
Was reading about some cafe on the A272 - Loomies?, just a bit North of you.Was thinking of riding out there when the Storm's fixed. Lighter evenings are on their way, YAY! So gonna suggest a ride out to the Dorset Bike Club. I'll give you a shout if it's a goer?

hey Chris, printed out your excellent, step by step instructions re: valve timing in preparation for fitting ROAS CCTs, now the front cylinder head is refitted.
Just one query I'd appreciate your comments on. With the RT mark correctly aligned, and cam lobes of rear cylinder facing each other, timing marks on the sprocets are not exactly inline with the head, they're both slightly high.

Is this due to chain stretch do you think?
Or is it posible the bike would run ok with both cams one tooth out?

I'm guessing that when the front CCT went it wouldn't cause the rear chain to jump? Haven't checked the rear CCt but assume it's ok - gonna be replaced anyway.

Maybe, if you're reading this, tonymon, you would have a comment.
Or anyone else in the know for that matter, would appreciate some clarification. Thanx

[benny hedges]

dont forget you want tension on the non tensioner side of the chain, ie not the side where the cct takes up the slack.
this may be why you are seeing the marks slightly out.
if you are not 100% confident, spin it round again and recheck.
see what it looks like stepping it back one tooth - you will see it's miles out.

chances are it's just a bit of chain stretch which really isnt a problem.
get them as close as possible, nip it all up and turn it ower by hand a few times checking the marks as you go so you know it's right.

if it's 1 tooth out front back or both, it will not run right and you will end up doing it again.

you need to replace both tensioners.

the rear will not have jumped a tooth if the front has failed - it has jumped the top cam gear, not the bottom drive gear.
take your time & get it right & if you arent sure, post. with pics

[tony.mon]

Nearest tooth is good enough.
It will (with tension on the tensioner side of the chain) show a little bit past where it should be; that's chain stretch.
Don't worry, it won't make a difference.

To get it exactly right and compensate for chain stretch you'd either have to fit new chains (and then THEY'd stretch, too, after a while) or slot the cam sprocket mounting holes and time it using a dial test indicator and set the cam lobe centres to exactly the right degrees of crankshaft- a huge amount of faffing about and probably wouldn't get you a noticeable gain.

So don't bother, and don't worry.

Coolio - sounds like you're my kind of engineer!
Re-checked & checked again after posting last night, figured that near enough was good enough so have put the front cams back on the head.
Just need those CCTs now.

[Arfur_Guiness]

....chances are it's just a bit of chain stretch which really isnt a problem.

many thanx for your words of encouragement.
I'm just a soft, southern, nervous nellie, jessie

but I do miss my Storm and want it back pronto.

Had to spank me D9 on Sunday morning. Thought I'd nip to work and "borrow" the works digital camera to take pics when disassembling the Storm motor.
In the week to get to work for 8am I have to leave my gaff at 7.20. But as it was Sunday morning with no traffic about, I left at 7.19 & managed to get there AND BACK by 8am.........all the while observing the speed limits of course
She might be a bit lardy but can still pick her skirts up and shake her tail feathers when spanked

Where's my CCTs!

hello mate, ref cct's mine took a week to get here to kent, something to do with them coming from northern ireland, it is worth the wait though ROAS makes a brilliant job of the polishing and manufacture
