Sally's woes! Locked up SRX600.

Clearly you need to run it harder!!

More concerted turning of the loud handle is necessary!

Aye Andy,

Plenty of 'Bombholes' up here, but no 'Revett's' and I doubt if I have the nuts!
Maybe have to shorten the gearing, or trade in for something softer! Then I can erect the screen, don the deer stalker, stuff the meerschum in the gob and chuff around a 5 mile circuit and that would be sad!
Look after yursel' and I'll sound a tootle next time I'm over the Kilpatricks or the Dukes ringpiece!

My regards, Bill.

Like one of these you mean Bill?

Aye Smudge,

A fine piece of cranial protection, in the best traditions of a 'sporting gentleman' from air they pairts!

Thank you for clarification of the intention!

My regards, Bill.

Further update to the saga.

Dismantled valves today and found that all 4 valve seals which are normally 'difficult'  to remove from the top of the valve guide had been behaving like YoYO's! None were attached to their respective guide and were free on the valve stems.

Have mic'd up the springs, valves etc and think that new valve seals, exhaust gaskets, cylinder head gasket and cam chain tensioner gasket are all that are required! Now removing thick deposits of 'gloopy' soft carbon over the baked on stuff, see link to inlet valves!

Inlet valves

Has anybody else had this problem, of detached seals? I can only think that the inner spring may have fouled the outer metal body and 'pinged' them off! There is enough inuendo scope in there to keep the Stalwart happy for days! 

My regards, Bill.

Bill,

Presumably the gloop is due to oil getting down the stems.

I know that the V6 form motors have valve stem seals which are like the carnival horses and go up and down with the valve.  But never noticed this on a SRX motor!  In fact, they are always tight when I find em (got to screwdriver them off...)

Were they pattern stem seals??  I have previously tried a number of different ones.  Some were too small, some too shallow, I was told that Vmax ones may be the way to go, in the end I used Genuine Yam ones for that application.

Aye Andy,

Yep, the gloop is definitely the oil going down the stems.

My experience with the SRX motor up until now, is the same as yours. Seals on tighter than a.....!

The seals weren't 'pattern' jobs, genuine ones from Yamaha. What makes me wonder about the inner spring pinging them off, was the thin rings of rubber left under the lip at the top of the valve guide, where they are supposed to be held! 

John's head gaskets have arrived and I am about to order the other seals and gaskets required from either Linsdell's or Fowlers. Not tossed the coin yet!

Watching the MGP? Link MGP

Go safe, Bill.

Lier,Lier, yur pants r on fire!

My apologies Andy and others whom may have read the above. Found the receipt today (sad) pattern jobs from Weemoto at £1-80 something a shot! Genuine ones from Fowlers, now on order at £5-60 something a shot!

Just a little something for the weekend Sir? I think I might prefer the sealing potential of the genuine articles rather than the 'pattern' parts after this incedent. Time will tell and it may be 'You gets what you pay for!' etc etc etc yawn!

A chastened numpty!

[andy230]

A-ha!

Too Scottish Bill!! Head-job for a few quids worth of parts.

(agreed tho, price of Yam seals is daft)

Someone told me today that a mate of his had spent £6,000 recently on a head job for his Manx Norton.

eek!

Was going to make some comment about a head job for a Manx Norton and then remembered that this is a family friendly site.
