Sounds like its making progress 
£500 is a fair chunk of money, but having said that he is doing a lot of work on it. Grinding the valves in is a time consuming job - I would know, I'm only half way through and its taken me nearly 6 months :lol
Sounds like the valves had a load of crap stuck to them - mine was like this as well but attributed it to the furnace like situation it was exposed to (carbs were removed so everything fell into the cylinders)
Did he give any reasons as to why it got so bad? It must have been running very rich. Maybe get him to take a look at the carbs
Dead eye/Dude.
The bike had been stood outside for at least six months, so he recons that damp air might possibly have made it's way into no3 cylinder, which probably had the valves in the open position, from when it was last run.
Also bear in mind, we are right by the sea here in Caernarfon, so the salt/damp air wouldn't have been helping matters.
I was led to believe on the forum somewhere, that the pre-injection models are prone to running a touch on the rich side?
The previous owner wasn't what i would call a serious biker, he only used it occasionally, so i doubt it got as much high speed riding as i gave it when i first got it, that also could explain the excessive carbon build-up?
Kev also mentioned that the two offside plugs were a begger to get out, although the other two weren't much better, the offside two were also very rusty on the outside, so maybe the fact it had been parked on the sidestand could have had something to do with that, i dunno.
Yes, it's been an expensive lesson, although we can also add two new Bridgestone tyres at £160, the inlet rubbers at £96 and the chain and sprocket kit at £89, so the actual cost will be getting on for nearly a grand, so all in all, the bike will stand me at around £2,500 by the time i get it back!!
We live and we learn eh?

mmmmmmmmmmmm bikes are like women !!
if they run rich they`ll empty your wallet quickly :b
treat them well and they`ll be good in return
either way you need to give them a good screwing now n then :lol :lol :lol :lol
waters wet, shit stinks !
At least you're getting somewhere with it now, it'll be interesting to see what you think of the performance when you get it back on the road. Good to see you too, pop in anytime you're over this way.

He's already stripped and cleaned the carbs, he said they weren't too bad really.

Had a call from Kev and the bike is back together and he's had her up to 150mph on the rolling road, at the redline.
The problem now seems to be that he's getting two traces on the readings, there seems to be an interference between the charging and ignition systems, with a higher than normal DC reading.
His advice is to replace the regulator/rectifier and see if that cures the problem, although he can't guarantee that it will, the problem is intermittent.
The readings from the alternator appear to be ok, so the problem is further up the charging chain.

Red98 - War & Peace, page 1.........i won't tell you the ending :lol
More people are born because of alcohol than will ever die from it.
Hmm... could this be a breakthrough in proving that the Regulator / Rectifier's are beginning to fail on the 600's :O
oh no...what have i started...looks like "stutter after service"is going the same way :eek
One, is never going to be enough.....

Yeah Paul, it's all YOUR fault! :lol
The bike is ready to pick up today, so now i need to find someone to take me to get it.
Looking forward to getting it back.

My mate picked the bike up from Kevs in his van the other day and took it to his workshop, because it was slashing down.
He has a tyre fitting machine and the new Bridgestones needed fitting.
He phoned me to let me know that when he removed the rear wheel, the rear pads fell in bits, so new front and rear pads were ordered and they have arrived today.
So all being well, i should be going over to pick the bike up tomorrow at some point.
Anyway, i got the info off Kev yesterday and for those of you who may be interested, here are the results.
Fault find: No 3 cylinder not sealing (valve seat rough). Remove head, grind in, clean and re-shim all 16 valves to correct clearances. New head gasket fitted.
As came in, leak rates were: 1 2 3 4.
4% 6% 35% 4%
After work, No 3 --------------------------6%
All bores tested by vac [Max on day 12" Hg] All same at 8" Hg now.
(Pump blocked)
No 3 plug had not been seated in head, or been changed for some time (rusty).
This caused hours of extra work to get new plug to seat down to bottom of thread. CR9E fitted with copper grease.
Coolant: This type of coolant was suspect, IE; unknown, so flushed and re-filled with with Good oat alloy maximum protection grade.
Valve clearances: Finished clearances and shims: 21/30.
EX.
164 - 170 - 172 - 169 - 166 - 170 - 168 - 170.
.29 - .22 - .22 - .22 - . 23 - .23 - .22 - .22.
11/20.
IN.
182 - 185 - 181 - 178 - 182 - 182 - 181 - 186.
.17 - .11 - .11 - .15 - .13 - .14 - .15 - .16.
New valve seals fitted.
New inlet rubbers fitted. All needed work to match head.
Work done with air grinder air tool.
Carbs stripped and cleaned, re-jetted to modified air box and high flow foam air filter.
This can be washed in warm soapy water each 4000 miles, dried and re-used.
Pilot at rest: 13.4 Air/fuel ratio.
30 mph: 13.5
50 mph: 13.6
70 mph: 13.6
77 mph: 13.7
90 mph: 13.7
110 mph: 13.4 *
130 mph: 13.1
150 mph: 12.8
* To obtain Max fuel economy, remove air corrector tube in airbox mouth.
Do NOT run over this speed(*) without the corrector.
It is safe to have the corrector in all the time if you wish.
Ignition:
1+4 2+3
15.11k sec. 14.80k
Coils ok.
Found to have distorted scope waveform (AC) while setting.
Also missfire at high speed.
This was cured with replacement Reg/Rec control box.
Note: Battery has one cell "bulge" due to this fault.
THE BILL!
Tune to suit + filter + jetting: £150.
Grind in all valves: £160.
Head gasket and post: £52.
Valve stem seals x 16: £40.
Shims (exchange) x 10: £40.
New coolant + flush: £8.
Reg/Rec cont box: £56.
Remove and replace head + clean: £80.
Match head to inlet rubbers: £20.
Fuel: £5.
Plugs x 4: £20.
TOTAL: £631.
EDIT:
Cam chain tensioner was found to have ball bearing at rear of spring.
This i thought was standard, however it would be unwise to remove this now without changing cam chain + spring, so re-fitted.
G ; )
Life's a long song....
Glad to hear it's been sorted - just need the test ride now ^^
Considering the work done and the parts needed, that doesn't seem like an extortionate price from a mechanic which is good I know from experience that those jobs can be quite long
Cheers Dead Eye.
One thing i forgot to mention, it seems that the bike (2002) has had a set of 1999 carbs fitted at some point, why so?...i do not know!
G ; )
Life's a long song....
You're welcome ^^
What's the difference between the '99 and '02 carbs? Thought they were identical :/
Could be for any number of reasons - previous set could have been playing up? Maybe chewed up some of the bolts on a service?
Hefty bill but it seems a reasonable price for the work done. Pretty sure the tensioner should have two ball bearings, one at either end of the springs. Hopefully all your woes are sorted now.
Dead Eye: I'm not sure if there's any difference in the year of carbs either, i'll try and remember to ask Kev the next time i see him.
I forgot to take my USB key over the other day, so didn't get the pics off his 'puter, will try and get them also, some interesting (scary?) stuff on there.
Dude: Yep, i was indeedy an expensive job but at least i can rest assured that the bike is likely to be at the best it can be, engine wise now.
G ; )
Life's a long song....
How do you know your current set is from a '99? Or is that just what Kev said? Be interested to find out
