I got a new Whizzer and a bunch of questions

Since I want a bike that I can ride around the state not just the block I did send my cylinder and head off to Quenton to detail. I am pleased with the work and it was done quickly and for a modest cost. I got the parts to Quenton on Thanksgiving Day After(Friday). The work was done and parts delivered to me the next Thursday.
We are slowly getting the bike back together. I hope to get it running again tomorrow on my first day off in a couple of weeks. I am working with Walt a local Whizzer dealer who also compliments Quenton's work. We got side tracked today when he received a couple of the new 2009 Whizzer NE-R Classic in and started putting it together.
I can't wait for it to run again. The heat treatment seems to have helped the threads in the cylinder. I am waiting on a local machinist to lighten the lifter rods. I'll report back when it is running.

Did you get the cylinder painted black too? I love the look and it does reduce the engine temp too but I'm not sure why.

I wonder why there is the thought that if you paint the cylinder or any other part of the engine it would run cooler! Paint is an insulator. The reason that the first engine cylinders were painted is because they were iron and would rust. On all the Honda's, the ones with iron cylinders were painted and the same engine with the Aluminum part was left bare. I like the look of the painted black engine but only for nostalgia, and I worry about mine getting hot with it. Have fun, Dave

Hi Egor,
Lots of opinions about paint & heat, but here are the facts. I have tested this theory about 25 times with a heat sensor, and the average is 50 to 75 degrees cooler using "black" heat paint. I have even tried different colors including orange, blue & white. I will let everyone else try to figure why this works and is true, but white didn't reduce the operating tempature, in fact on a couple of tests it increased the tempature about 10 degrees. I have seen many explainations, but when I raced for HD they painted the original XR750 aluminum test cylinders black.

Have fun,

GOOD MORNING EGOR, AND QUENTON; LIKE YOU, I NEVER THOUGHT IT MADE SENSE TO PAINT CYC BLK EITHER. YRS AGO HARLEY D DID SAY TO DO IT, AND THAT THEY WOULD RUN COOLER. ITS COOL THAT QUENTEN RAN THE TESTS. WAS HE A GUEST ON MYTH BUSTERS!

Mine is now BLACK!!! I am sold that Quenton has done me right at every turn so I trust him here too.

Hey Lenny
Have you run the engine yet? Wait till you hear the difference in the exhaust note. With the higher compression it has a much beefier sound. (at least to me it does) You will notice the better overall feel of the engine.
Enjoy the ride
Jim

Quinton - I think you are correct in your readings, but think about it you are reading the outside of the paint, if it is doing its job you are reading the paint and not the engine. I wonder if you would bare off a spot next to the paint and take a reading I wonder if it would be the same. There are instances when you want to retain heat, I never understood how in the fuel mileage runs they insulate the engine to keep the heat in, go figure. Have fun, Dave

Hi Egor,
99% of the time I use head temperature [no paint]as the reference. I have checked carburetor temperature, exhaust temperature, crankcase temperature, and cylinder temperature, both fixed sensors and infrared. For a short time I even checked vacuum, oil pressure [crankcase] and oil temperature. I have had Whizzer motors run above 650 degrees and some that run under 475 degrees. I have seen pistons raise or lower the operating temperature. I have seen different brands of oil run different temperatures. I have tested spark plugs that raise or lower the temperature [all NE motors using the NGK C7E sparkplug run hotter than a head fixed to use the NGK C7HSA]. Please don't think I suggest heat ranges control temperature, just plugs that are too long cause problems.



Let me start more puzzles for you. Which is better a smooth intake port or a rough version. Which produces more usable power a short fat intake or a long skinny version?
What are the advantages of an oversquare motor compared to a square or under square motor.
The preceeding questions are the main reason my Whizzer motors exceed 8000 RPMs and do it rather quickly. The answers to the questions also explain why my 4 stroke Ducati Desmo singles could out rev most 2 strokes on the race track.
Over the 15 years I raced I watched many theories fall by the side because of proven results. For years I couldn't understand why my XR750 was able to win so much against large sums of money and multi cylinder motors. One day I discovered how important USABLE power really is. A 450 Ducati Desmo was dropped off for me to test, and after spending almost all day at the track, and every bike there was "dusting me off", in anger I quickly shifted all 5 gears, and discovered the problem. I hadn't yet learned about usable power, however when I discovered I wasn't going to make the corner because I was well above 100 MPH, I soon learned the true meaning.
The real magic is in the details, not what someone thinks is better on a computer or someones theory. In 2005 I was told a Whizzer motor won't produce enough vacuum to lift the fuel from the main jet on a 26 MM carburetor [btw I have already used a 29 MM Ducati carburetor on one of my Whizzer test motors and it works great]. In 2006 I was told the exhaust pipe on a single cylinder flat head motor won't make much difference in power [I went 3 MPH faster by just changing the pipe], in 2007 I was told no flathead Whizzer could outperform a OHV Whizzer [want to see my thropies?], in 2008 I was told a Whizzer flat head motor couldn't turn any where near 8000 RPMs [try 8820 in 150 feet].
Have fun trying to figure which side of theory really works and which side doesn't.
