View Full Version : The Kat's not well



dangerous
14th May 2006, 19:04
well I have been working on the new Kat over the weekend and something just isn't right... seems to take a while to warm up and has a mag drop at a certain rev, ya cant feel a miss but it does not sound right.

Checked the tappit clearances out and all seems ok, cams are good apart from exhaust lobe 2, which dosent look as shiny as the others.

Now check out the state of the plugs in the attached pic... #2 not looking good aye? why is that? heres the compression results

rounded up to the nearest 5psi
165
145
160
165
actual reading
165
148
162
168

My 1st thought is burnt valve as the exhaust sound is the same as I have heard before when this has been the case.
However it has been pointed out that if a valve was burnt out then the compression reading would be 0psi.

What do you guys reckon? I havent had a chance to strip the carbs yet...

Not knowing enough but at a guess (going through the options)
Cacked head?
Rings?
Stripped plug thread?
Burnt valve?

Burnt valve is apparently out, so process of elimination....

(Not much help eh?)

You have been told how to diagnose if its rings or valves... why dont you start there?:confused:

Doesn't look like the plug has been firing. Try a new/replacement one. Could be duff HD lead connection or cap. Where all 4 headers getting hot? Could explain the strange exhaust note if one cylinder wasn't firing.

This happened with Gerty. Turned out one contact on the coil had erroded away and not supplying ergs to the sparktplug.

Redo your comp test with a teaspoon of oil into each the plug hole. If the compression goes up then rings if stays roughtly the same then valves. As a rule the highest comp pot will have the least rise and use this as a base. So if pot 4 goes up by say 5psi and pot 2 goes up by 20 then pretty safe to assume rings. If pot 2 also goes up by about 5psi then rings.

A burnt exhaust valve will still have compression in the early stages.

For the the sooty plug, is it wet and oily soot, particularly in right deep in the plug (rings), or a dry fluffy soot (carb)?

Have you run your finger nail on the cam lobe?

Still it could be both at the same time!

Mate I've had a few of them thar bikes.They still seem to keep on keeping on even with burnt valves. Pull the head off and Ill betcha one of the zorst valves has a bit burnt off of it.
I'd pull all the valves out and give em a lap in

Well, I would know if it was not firing on all 4, but theres something in the exhaust not that isn't right.... it is, just not producing all the power.

From a wee magic book :sherlock:

Compression range is : 9 - 12 kg/cm2 which is 128 - 170psi

and heres a plug diagnosis chart for you so you know what your looking at :bleh:

Bonez
14th May 2006, 20:33
Well, I would know if it was not firing on all 4, Prey tell how? The slow to warm up description you made sounded very similar to what happened with Gerty. Once warmed up she'd fire on all 4 but not on every firing stroke. Replacing the coil sorted it out.

That chart indicates it could be weak voltage also.

He's already been told to do that


Redo your comp test with a teaspoon of oil into each the plug hole. If the compression goes up then rings if stays roughtly the same then valves. I told him to that earlier today after he did the initial compression test


Have you run your finger nail on the cam lobe?
Did that yesterday when he was checking the clearances, the lobe is a different colour but it isn't marked or worn

Gave him that to, if he spent as much time on his bike as he does attention seeking on here it'd already be fixed


as I said to W I will do the old oil down the plug hole when I get the chance you've already had a chance to do it well before you posted this :bleh:

I had a GSX1100 years ago and it had a cracked head with low comp on 1 cyl. I couldn't afford to fix it so bunged it back togeather and rode it hard for another 10k before selling it to a unsuspecting punter. Dont worry about the comp you are looking for a electrical or fuel fault. Good old trademe strikes again, yellow paint anybody. Go the cb250, the Kat will look good in the pits:laugh: .

14th May 2006, 21:45
I'd be working from the plugs back firstly, guaranteed with the age of the Kat if the plug caps aren't getting worn, then the leads will be stiff & most likely breaking down internally which would be causing the misfire.
If its a coil it may also effect #4 cyl as well but it doesn't look like it is.

Also the Plugs are one grade colder than should be in there (D8EA)

The compression issue could be a result of the misfire anyhow with carbon build-up on the exhaust valve seat, so a lap & re set could be useful too.

Very high probability that the diaphram in the fuel tap is rooted. I had exactly the same thing on my GSX1100. What happens is that when the diaphragm is rooted is that the fuel overlows carb 2 (Fuel overflows carb 2 by getting drawn through the vacuum line [vacuum line to feul tap originates from carb 2]), resulting in a plug that is black and sooty. I tried a rebuild kit from Colemans without success (with a try first $25 IIRC) then scored a new tap from Don at Cycle treads ($180 I think). There is a test for it but I cannot remember what it is - check www.thegsresources.com

Edit - Disconnect the vacuum line, plug carb and feul tap, switch to "prime" and ride (switch to run or reserve at end of ride so as not overflow carbs). Plug colour should return to normal. If it does its the diaphram thats rooted.

Hmm, if it was an H-D I would say swap leads over and see if the other plug fouls BUT seeing as you're hell-bent on messing with multi cylinder Devils toys I would swap the plug with another cylinder and see if the same cylinder fouls - then at least you would know if it was the plug or not.

Get somebody with one of those magic 'lectric gizmos to check coil for output and lead for breakdown.
ARE all exhaust valves opening the same amount?
And don't forget ZZRs advice.

. . . If its a coil it may also effect #4 cyl as well but it doesn't look like it is. . .

You mean cyl 3. -2 & 3 are same coil, typo I'm sure.

I'd suspect fuel & would have thought tap was leaking & some crap under the float jet needle of carb 2. But ZZRs idea I wouldn't have thought of, sounds reasonable. I'll try to remember that one cheers. Check float height as well & tiny chance some how the choke was stuck on only on that cylinder, but that is totally unlikely.
If the plug cleans up try running it for a good thrash & the comp may come up in that cylinder, but I wouldn't worry about it if there is another explanation for the plug fouling.

When I got my GS11 the comp was all less than 90, bit of a lap & some miles & it came up ok.

terbang
15th May 2006, 11:00
If its # 2 cylinder then its the fuel cock diaphragm. Is a common problem on GSes..Find the rubber pipe that runs from the cock to the inlet side in front of the Cyl 2 carb (thinner than the fuel line) disconnect it at the cock end and block it with something. Turn the cock to PRI (watch out for any serious leaks) start it up and if the diagphragm is at fault then you should notice an instant difference.

:doh: My bad :shit: I'm full of the flu so i've got an excuse.

I'd still replace the leads though if their even slightly stiff (had 3 bikes do exactly the same thing over the years).
FTW: i'd recommend, Eagle 8mm LPG series hi-temp silicone spiral-core cable. slighlty heavier than stock 7mm M/C plug leads but excellent in conductivity (could almost weld with the spark produced).

And I've got a good idea of who/what the culprit is to have caused the problem to start with but I'm keeping the mouth shut otherwise i'll get scorned, but its clearly visible in the pics in the other thread.

Remember reading somewhere that the highest and lowest pressure reading should be within 10% of each other. The Kat is just outside of that. All the best with your fault finding.

Thanks to those that have P/Med to ask how the Kat is doing :Punk:

Now managed to get out to the garage today and after another spin into town for a rear tyre... they got the wrong tyre in again, but I did sort the rear brakes out.
Now when I got home I figered lets do the comp test again with oil... 1st did a dry test and FUK ME #2 was reading higher than previously... but #3 was down WTF... anyway heres the results
168
159
132
158
#3 was down 30 odd psi from last w/e whats that about?
anyway 5ml of oil down the hole and it came up to 180

And at this point the batt went dead so that roots that idea... so I blocked the diaphram hose off and turned it to prim.
went for a blast gave the bitch arseholes and have not as yet checked the plugs, I'll do that in the morning and re try the comp test.

The blast I just did on the Kat went like this, if I open the taps up slow it pulls through the revs ok... but if I dump the taps open it puls well at low revs then between 5.5-6.5 it goes dead and misses a bit... hits 7k and hauls arse like nothing touches 8.5 k and the tacho goes directly to the red (clutch slip maybe?)

so apart from the 5-6 dead zone it is very smooth... but... aint 80's brakes crap :woohoo:

yes K&N fitted and fuel line is sweet not a scaret of shit even on the tank filter.

Now... today after the batt was on charge over night I did another comp test and all 4 pots were withen 12psi so I didnt worry about the oil thing
170
158
158
170
I have no idea why the 1st 3 tests had #2 at a lower comp but all seems well now.

Ok sooty pulg, well after putting cleaned plugs back in and having a wee spin around the hills I wiped the plugs out and what ya know #2 is sotty again... now the fuel tap is on prime and the dia hose is blocked off so thats that theroy of #2 running rich out the door.

Ok so ring about Repcos for the correct plugs 8 not 9 temp and man... why the hell do they only stock ONE plug at each store.
New plugs in and still 5-6rpm it wont pull.

Figgered fuk it had enugh so I put it all back togeather including the filter air box lid on for the 1st time.
One last blast and yeeeeeeeeeehaaaaaaaa, it runs sweet as, pulling right through the rev range.

SO if it aint broke dont fix it... well in this case put the bloody air box lid back on :blip:

Wet black sooty or dry fluffy? Dry and fluff is normaly the carb, wet black is normaly caused by oil. It can get past the rings or valve guides. There are little black cap things that go on the top of the valve guide that some times shag out.


Ok so ring about Repcos

Repco is the most expensive place for plugs anywhere. I use a place in New Lynn that is half the price (yes half!)

I didnt do the 4 pod filters just the replacmet filter in the 2nd air box, remember this was doing the 5-6rpm thing before the filter was replaced... as it was so dirty (spiders and all kinds a shit in it) I left the lid off to help it breath.

When I got my GS it ran like shite and was super rich on low throttle on pots 1 & 3. I checked the pilots and air screws and they were all over the place. I farked around with 1.5 out on both and then just did air screws - no difference. 1 & 3 always ran super rich.

I then pulled the carbs out (I'd like to meet the wanker at suzi who designed the gap between the carbs and airbox on a GS - guess he left there about 25 years ago!).

Anyway stock main jets, slide heights roughtly the same (gave them a tweak), and same pilots.

I then checked the floats and the tangs on the floats 1 & 3 were visually "bent" cf 2 & 4. I then bent them the same as 2 & 4 and hey presto! Took a bit of tweaking to get the same measurment of float height to the carb.

Ok just a quick update, after last weekends racing the Kat has droped #2 again, well it comes and goes... so carbs out and looked at this week.

NOW I have had a problem with the starter of late... get this the starter sticks on... but if you turn the key off or kill switch it keeps on cranking... thers nothing I can do but wait till the batt dies as it takes too long to get at the battery to disconect it.

WTF do ya reckon thats about???

13th June 2006, 22:26
Faulty solenoid, or faulty starter button. Possibly the wiring in between, but seeing as those are mechanical, I'd look at them first.

There's always the potential of water in the electrics.

Hey D, is the Kat old enough to be fortunate enough to have a kick start option?

Ixion
14th June 2006, 09:17
Starter "stuck" will be solenoid. Switch would stop on turning the key off.

The main terminals of the starter solenoid connect the battery direct to the starter. If the spring which disengages the contacts once the armature is non energised fails, or the contacts themself become damaged the solenoid may stick.

This can be caused by using the starter for too long a period at a time. The prolonged use causes the contacts to overheat and become rough and pitted due to the surfaces partially welding together. Thenceforth, they do not make good contact because of the rough surface - which means the surrent has a smaller area to pass through, which means local oveheating, and so the cycle continues.

Ixion
14th June 2006, 18:40
Yep. Look at the battery. There will be a thick wire that goes direct to the solenoid. And a thin wire also at the solenoid. And a thick wire from the solenoid to the starter. In the solenoid are two big copper contacts. And a electromagnet. The thin wire is supplied with electricity through the ignition switch ,kill switch and starter switch. When all of those are on, electricity flows through that thin wire to the solenoid, energising the electromagnet. That magnet shoves the two big contacts together. They connect the two big wires together. One big wire direct to battery , no switches in there , other big wire direct to starter motor.

Normally , you turn one of those switches off, no electricty to little wire, no magnet, contacts are pushed apart by a spring, no connection through the thick wires.
But -- if those contacts stay stuck together? They don't care now if there's any current int he little wire. They're going to connect the thick wires come what may. Battery direct to starter motor.

Have you ever removed a starter motor from a car with the battery still connected, start motor still wired up and the ignition key located far away on the kitchen table?

Produces a massive spinster moment in your hands and your pants when it suddenly comes alive after accidently touching something metal on the solenoid points!

The Kats purring again
Well, the Kats out of ICU and back home in a comfortable position in the garage.
Now the findings were as we know rooted solanoid, next was a shaged fork seal due to rust and pitted holes on the fork leg... fixed for the mean time thanks to the old trick of sanding the shit out of it and epoxy.

Now #2 pot... carbs, full of water as were the other carbs, but #2 the diaframe had collapsed and the emulsion tube was corroded, the carb also had a different sized jet in it to the other three.
I scored a set of 1100 carbs but it turned out that they were the same size as what the bike already had.

Next w/e is rd3 BEARs so time will tell, but its sounding different and starting sweet.
