I ordered and paid for a set of Boge shocks from the US in the evening of the 11th, they arrived in Australia on the 13th in the morning. Took 3 days to clear customs and get despatched from Mascot Au on the 16th. Hopefully be here tomorrow or Friday. Doesn't grind my gears, but just amuses the hell out of me that they took only a day and half to get to AU, yet sat for twice the time over here before moving on into our local postage system.

Nice effort Teddy, that box is awesome. I really love the guys vid with his experience of trying Vegemite for the first time. :y:

Cool vid that. :blush: Love the sound of a ballsy NA motor, nothing like it. Really into watching vids of Marc Fleury and his 300 odd HP S14 (BMW motor) powered E30 drift car atm.... Not really a fan of drift, but that guy is great to watch doing demo runs on hillclimb circuits, plus his car sounds so good.

Waiting for my new laptop to turn up. I feel like a kid at xmas. I was under the impression that it would be here today, but I misunderstood. :blush: If I had of got an off the shelf model rather than an optioned up one it would have been. Oh well, should be worth the wait.

Yea I'm in Gatton Shire. You'd think so, but there are a lot of dumb ignorant idiots out there. I'm not in town but live on a housing estate where everyone is on acreage. Can't quite tell where the source of the fire is, over the other side of the hill. It stinks real bad, give you a bad headache in a few minutes kinda smell. :)

Mozzies: The little f@$kers were out in force this evening after having a shitload of rain last week. Haven't had a problem with them in ages as it has been so dry. I must admit it is nice having green grass for a change. People burning shit off: Someone is burning some crap off locally atm. It sux as it has been so hot today and now would be an ideal time to open up the house and get some fresh cool airflow through the joint to clear out the days heat. There is a nice cool breeze now outside, but we've had to close the whole house up as the smoke smell outside is very plasticy and stinks something shocking.

I found this Mikuni PHH manual. Looks like your carbs are a bit different, but that manual gives an explanation of how the starter disks work. Hopefully it can be of some use.

Cutting compound is what I should have said. Many manufacturers sell it. It is pretty coarse. Used for putting the initial shine on fresh paint, or restoring heavily weathered paint. Great on stainless and chrome trim which is a lot harder than paint.

stevejw, that's not good. :) I bought a set of those rubbers from lilavadee a while back that are still in the box. I intended to replace the 40+ yo crap looking rubbers on my ke15 when I get around to painting it. After seeing your pics it looks like I shouldn't bother, the originals look better than your one year old ones. Not good at all.

I've got a ke10 that looks very similar to that (except has the holes for the chrome side trim filled). It has been painted in a tacky straight tinter white and has paint peeling off it due to lack of preparation. I was thinking I should take it for a drive at high speed and blow all the paint off of it. :) I've found the coarse green buffing compound you use on fresh paint is excellent for cleaning up chrome (trim, bumpers, hubcaps etc.) with very little armwork required.

Yea, I guess it comes down to the compressed head gasket thickness. Having a look around it seems .030" is the recognised minimum safe piston to head distance. Some have run lower, but everything needs to be spot on.

How far do they protrude? As previously stated, measure with a steel ruler and feeler guage. I think your main problem was the firing rings of the old head gasket overlapping the bores and the pistons hitting them.

If his pistons protrude above the block deck height, this won't work, and the motor will not turn over. Piston protrusion is a tuning trick to increase squish and provide added detonation resistance.

That's the way they were designed. Ticking time bomb. Be thankful it happened at home while stationery. Out on the road it could easily cost you a motor.

There is nothing wrong with the pistons slightly protuding from the deck of the block. So long as at high revs any rod stretch isn't allowing piston to head contact. Personally I'm thinking the old headgasket was a 3/4k item and the piston was contacting the firing ring of the HG.

I've had a welschplug pop out on an old 3k bigport head before. Crap setup, overated heads. If you are going to run one, ensure the welschplug is epoxied and staked in place.

No, that's from Autohausaz. $44US cheaper than Pelican Parts for the pair. :S Have been ordered and should be here in a week or so. Ended up costing $310 AU delivered to my door (well my local post office) with paypals conversion rate. Shitloads cheaper than sourcing locally. :o

Good stuff. Have you CC'd the combustion chambers? I'd do that to verify the CR before bolting it all back together. Not hard to do with a bit of clear perspex with a hole drilled in the center and a syringe. Turn head upside down and level. Some grease around the outside of the combustion chamber, stick perspex down. Fill syringe with water and proceed to fill combustion chamber. Keep track of how many ml (1 ml = 1 cc) you pump in to get level with bottom of center hole in perspex. Work out compression ratio. Off the top of my head the head gasket volume is about 5 cc. Won't be quite spot on with the valve cutouts in your pistons, but better than later on discovering you have a hot running motor that pings its' head off, due to too much compression. Oh yea, if you don't want suss looks when you go to the chemist, just tell them you don't want the needles to go with the syringes. A syringe with a bit of vacuum hose on the end of it is a great tool to keep in your toolbox. Great for sucking water out of those sparkplug tubes after degreasing a K series motor. Also good for sucking some fuel out of a fuelcan and squirting it down the throat of a carb to start a motor that has been sitting around a while.

Just wanted to know so I could work out whether or not it was a 3/4k headgasket or a 5k one.

Got the part number of that gasket you used?

What head you using? 5k now? Does it have the protrusions under no1 and no4 spark plug holes? If so it should be used with 16cc dished pistions. I suggest you CC the head and check the compression ratio. Valve-piston clearance can be measured with some plasticine on the piston crown... oil the valves, dummy up the head and turn over the motor. You take the head off, slice the plasticine at the thinnest point and measure the valve/piston clearance.

I don't know.... To me it looks like the distance between the bores is narrower on the bottom end than that of the head gasket. I kinda think the pistons are hitting the firing ring of the headgasket from what I can make out from the pics. Do you have a vernier caliper? I'd be measuring the distance between the bores of the block, and comparing to that of the headgasket.

The one I posted wouldn't have any lag. You could have full boost at idle if you wanted to. They need to run brushless motors. Anyone who's played with rc stuff in recent times will know that brushless is the way to go, you can make 3 times the power of a brushed motor for a given size with 90% efficiency compared to something like 60-70% for a brushed motor. Yea you'd need some serious wiring and a good reserve of grunty batteries, plus a decent alternator to recharge the batteries between bursts with that electric supercharger. They do work though, which is more to be said for the cheap ebay fans. LOL.

At TDC are the pistons level with the top of the block or a tad lower? Alternatively do they protude slightly above the deck of the block and have possibly been hitting the firing ring of the headgasket? It is a 5k headgasket and not a 4k item? I know it may seem a stupid question, but once I bought an ex-turbo 5k and the guy had problems with blown head gaskets... He was running a 4k head gasket. Just trying to cover all bases.
