Welcome to the board mike! If you wanna take a spin on a 250R i'll let you ride mine

HondaATC,

The "powervalve" or "ATAC" system if I remember correctly, was a chamber located on the left side of the cylinder. The system did not operate as designed for the CR, but the cylinder was still a giant improvement over the stock ATC cylinder and anything I was getting from Paul Turner at that time.

Like I mentioned in the previous post, Paul "ported" the cylinder and it made LESS power! Steve Carter then reassembled the top end using ATC rings which were chrome against this cylinder which was also chrome plated or nikasil. It self destructed during a National at Liberal Kansas in 1985.

If these cylinders are run "as is" the port timing is very good. They do not need to be modified if the correct pipe is used. This set-up was very fast when I originally used it.

This sounds like a really good mod to do with the waterpumper Rs. I'm gonna guess since the cylinder was from an mx bike it shifted the power more to the top of the RPM range then the stock cylinder, is that true? Also you mentioned a pipe for that cylinder, did you use a modified ATC/CR pipe combination was an all new cone style pipe constructed? Thanks for your time Mike.

The cylinder didn't really move the power band up. It made more power at all RPM's. Of course it made more peak as well, so I would say it made for a wider than stock power band.

After my engine went south during the National at Kansas that year while running the CR top-end, I was never allowed to use it again. ONLY Paul Turner modified top ends were allowed. They were all junk except for the "one that got away" that we had for the San Jose National at the end of the year. That one ripped..........

Mike,

I read a post by Dean Kirsten that talked about how uptight Wes McCoy was.
You mentioned that Wes was present at San Jose (at the teardown of your "good" engine.) Was this the way he was or was he this way due to Honda management?

[3WW Star-CoeShow]

mad_max,

I raced for the ATC team for nearly 5 seasons. In the beginning Wes was much more likeable and easier going. It wasn't until Kawasaki formed a team to race did he start to get irritable. The hiring of Bruce Ogilvie was also a HUGE mistake, along with bringing Paul Turner on board.

I heard from an excellent source that Paul Turner was actually FIRED from the MX team!! I don't recall what the reasons were, (nor do I care) but the politics and "TEAM" really started to fall apart starting in late 1984.

Wes did many honorable things and was clearly a mover and shaker at Honda. I hear he has recently retired from Honda. he must have been there for 30+ years in many different capacities.

I always respected him as a person, but he also did some "odd" things at the races and at the office. I wish him a happy retirement.

Like many things in life, hindsight is 20/20. Wes (like myself) may have done things entirely different if he had the chance to do them over.

The things that Bruce Ogilvie did were unforgivable. I have 0 respect for that man.

[Dammit!]

Tell us how you really feel, Mike.

By the way, I believe quite a few of us are going to be at Glamis for Thanksgiving weekend. You should come out (even if it's on a quad or something... we won't laugh... really).

[3WW Star-CoeShow]

!,

I put so many miles riding at Glamis back in the eighties that I am STILL burned out on that area. I used to take my pre-runner with the dual oscars down to Glamis with a 55 gallon drum of premix in my pickup.

We/I would ride almost non stop, day and night until the fuel was gone. Would do that on many a weekend. Now I understand theres no such thing as an "off" weekend.

With so many more dunebuggies and quads sold since I was last there in 88, I can imagine it's pretty crowded these days.

In the mid eighties you could ride sometimes for days and never see anyone else in the whole dune system!! From Gordon's to Glamis!!

Anyway, I don't have much interest to go back to the sand, especially on a holiday weekend, sorry.

I hope you have fun though! Ride safe.

Mike,
This is great having you here on this site!
Thats alot of great reading!


One question....Do you Remember this guy?

[3WW Star-CoeShow]

Ido not recognize the person in the picture, but because of the words around the link to the picture I am going to guess that it is Micky Dunlap.

Am I correct??

[R Nutt]

LOL...........Yes its Mickeys face photoshopped onto someone else.

Mickey is a regular poster at Kawieriders.com , He's .....shall i say "different" people over there either like him or cant stand him, theres no in between....

Anyway, i read through the posts and maybe i missed it but what are you doing now, as far as work? are you still involved in the offroad business somewhere?

Dunlap and sparks do motor work, I saw jimmy white this past feburary in indiana at the dealer show.....how about you?

[R Nutt]

One more question for you....
Back in 85, Dirtwheels had a rider of the year poll, 10 riders---

(Coe,Dunlap,Hart,Luce,Sparks,Sundahl,Tokay,Wax,Whi te, and Wright)

And it was up to the readers to vote who will win the Nissan 4x4 king cab.

Who Got it?

[3WW Star-CoeShow]

R Nutt,

I have been working for Solar Turbines Inc. for almost 15 years. Solar is the leading manufacturer of mid size land based turbine engines and compressors.

Our equipment is primarily used as the means of pumping oil and gas through miles of pipeline in the *.S., Middle East, Europe, Alaska, and everywhere else Oil is being drawn out of the ground.

The company grossed over 2 billion last year. I work in the R&D section of the company primarily in the surface engineering department.

If I remember correctly, Jimmy White won the Nissan truck in the contest.

Who will ever know how biased or accurate the results were??

I figured Dean Sundahl was going to win it hands down.

Mike, speaking of Sundahl how did you two get along?

[3WW Star-CoeShow]

Mad Max,

Dean Sundahl and I got along very well. We were neighbors in ElCajon and were also team mates in many off-road races. Dean was one of the first riders to have been selected to be a rider for the ATC team. He had already been with Honda for some time before I was selected to join.

We did many things together besides riding ATC's. I would say that we were pretty good friends for some time. Our desire to win races began to strain our relationship as we ourselves became each others main competition. He wanted to win and so did I.

After I won the 1983 National Championship, we became more distant, and eventually stopped being team mates for off-road races as well. Starting in 1984, Curtis Sparks and I became team mates for all off-road events.

If ever there was one person that deserved to be called "The Best" ATC/ATV rider of all time, Dean would be the person I feel should be selected. He was VERY successful as a racer and amazingly talented on the 3 wheeler. He was instrumental in raising the bar in ATC racing. I learned a lot from him as did many others.

Dean was the "Fast Guy", winning most of the races when I first started racing ATC's. EVERYBODY looked up to Dean Subdahl in the early days of ATC racing.

"KING DEAN" is a perfect salute to this man. He earned this name and I am honored to have known him well. I also am proud to have been one of his riding team mates and main competitors.

....Starting in 1984, Curtis Sparks and I became team mates for all off-road events...

When you say "team mates for all off-road events" do you mean that you trade off riding certain sections of the course?

I remember Dean getting a lot of press for his desert racing, nice to know that he is a good guy.

Thanks
