Re: KR> CHT probes

[Robert Dunleavy via KRnet]

 Be very careful using a ring terminal under the spark plug. In my experience 
in my volkspane it was very difficult to prevent them from leaking, which lets 
the cylinder suck in air and run lean, ie hot. In conversations with Steve 
Bennett, this was why he had moved the probe to a cylinder stud. I like the way 
that the aero vee mounts the probe but never tried it myself, i moved mine to a 
cylinder stud as Steve recommended and never had any more issuesrobert

I agree with Donald, buy the spring loaded pushrod tubes that can be installed 
after you put the heads on. If you use the stock pushrod tubes it is to easy to 
have a head on a little crooked and damage the head, trust me I did it and had 
to buy a new head. I used the spring loaded pushrod tubes  after that and never

KR> glassing procedure for wings

[Robert Dunleavy via KRnet]

There was a brief discussion a few weeks ago, but I want to make certain I have 
this correct so please bear with me.
The KR2s manual I have is dated Jan, 1990 and was acquired last year from 
NVaero.
Stub wing procedure is as follows ( and so I don't have to restate it each time 
glass is cut and laid on a 45 degree bias).
para 10.11 first layup from front of forward spar to rear of wing (top side).
para 10.12 second layup at least two inches onto first layup (over front spar) 
then around leading edge approx 3 inches past cordline.
para 10.16 (bottom of wing)  same as 10.11 and 10.12.

outboard wing sections are basically the same except para 10.32 calls for nose 
layup to overlap spar caps top and bottom.
In summary it takes four layups: 1. leading edge of front spar to rear of wing 
(top). one layer of glass. 2. front spar (with appropriate overlap) around nose 
rib to form leading edge layer one. two layers of glass.3. same as step one on 
bottom of wing. one layer of glass.4. same as step two forming leading edge 
layer two, using two more layers of glass. four layers total.
 sorry this got so long but it's a lot easier to make certain I get this 
correct rather than having to redo it...thanks...robert

KR> Broke Brake

[Robert Dunleavy]

i agree with the use of a small oil pump forcing the brake fluid in from the 
bottom. I tried using gravity to bleed my clevelands from the top and never 
could get them to work. used a small oil pump and bled them from the bottom 
with no problem...robert

Are the brake cylinders fed fluid by a remote reservoir that's mounted
higher than the cylinders, or are the reservoirs built into the
cylinders? If there's no reservoir mounted higher and filled with fluid,
air bubbles in the cylinders are a real possibility.

My experience has been that bleeding the brakes is best done with a
simple mechanical oil pump, think oil squirting gun with a plastic tube
on the end, or even a pressurized garden sprayer, filling from the brake
bleeder and up through the rest of the system. This way, air bubbles
are carried up (their natural direction), and if there's a leak
somewhere it becomes apparent. If pulling a vacuum from the top of the
system, if you have a leak it will suck in air bubbles, and it will not
be obvious if it's a small leak.

Exactly the same as I recommend.? I find that a small pump oil squirt can is 
more than enough to completely fill one side including the reservoir.

In an effort to learn something about the Suzuki GSXR 750 brake cylinders, I 
did a google search and found a large recall of those master cylinders due to 
an incorrectly placed port between the master cylinder and built in reservoir 
causing the master cylinder to trap air.? I don't suppose you happened to get a 
screaming good deal in a set of recalled master cylinders

KR> customer service at nvaero

[Robert Dunleavy]

It seems to be human nature to only report the bad so I thought I would try to 
break that trend. I have been getting more serious about building a KR2s and 
have been studying the plans in detail. I realized last week I was missing a 
drawing. I sent Steve an email about this and had barely hit the send key when 
my phone rang. It was Steve at NVaero, I told him what was missing, he said he 
would mail it to me in a week or so and we had a very nice talk about kr's in 
general. Went to the mailbox today and there was my missing drawing as promised 
(thanks Steve). I know there has been some negative reports posted about 
NVaero's customer service but ?this is my second dealing with Steve and I have 
had only good experiences. I think Steve is doing a great jobthanks

KR> Cylinder Heads Again

[Robert Dunleavy]

Roger, I'm running a great plains 1835 on a vp-1. just wanted to respond to 
your comment about valves leaking. In my experience with vw's I have found it's 
next to impossible to keep the exhaust valves from leaking. I've had leaks on 
new heads that have never been run. If you look at the guidance that's coming 
out for A&P's lately a small leak is nothing to get to excited about. I have 
400 hrs on my engine and it's still running strong. I do use the synthetic oil 
as i also have seen reports that this helps lower cht. I have seen reports that 
you should not use synthetic oil if you are using leaded gas but Haven't seen 
anything on this in a few years so not sure if its still accurate. ...robert

degree temp yesterday, and after idling to the runway and a quick runup,
it was at 400F as I turned crosswind, and I wasn't even at pattern
altitude yet!<

I spent some time looking through my engine log book for my first KR and the 
CHTs were always in the 400 to 425 degree range on climb out and then around 
375-400 in cruise. The last set of heads on that engine were CBP 044s. I 
purchased then 1990, and had 150 hours on them when I crashed in 2009. When 
I tore them down the exhaust valves had a lot of wear in the seating area 
and all the valve spring retainer groves were really worn, along with the 
valve guides. I had done many different things to get them to run cooler 
including installing adjustable cowl flaps. I gained the most by smoothing 
out the cowling exits and changing to full synthetic oil. I remember reading 
some people reporting a? higher CHT using synthetic, but I did get a 
consistent 25 degree drop in CHT. Of course, the oil temp went up from 170 
to 190 in cruise. Not enough to worry me.

I have rebuilt the old 044 heads with new valve guides and new 214NSS 
stainless valves from CBP and recut the valve seats with a Neway cutter. I 
currently have about 75 hours on them. I Flew on a 100F degree day over the 
weekend and here are the temps I got.

Climb:? 330F, taken under a cylinder head stud and 410F under a spark plug. 
(I think I got hotter than that).
Cruise at 6500 ft. 3200 RPM, 145 MPHI:? 300F under the stud, and 350F under 
the spark plug.

The engine is a 2180 with the compression ratio set at 7.2:1

I always pull the prop through four blades to make sure the valves have not 
developed a leak. I have 75 hours on the heads and the engine is still 
running strong and smooth, but now after shut down and pulling the prop 
through I have a slight hiss coming from one cylinder out the exhaust pipe. 
If I let the engine cool for 10 minutes or more the leak goes away. Maybe a 
sticky valve guide?

It will be interesting to see how your DPD heads hold up.
