How am I doing and what’s on your mind?

We are a few posts in I’d like to take a moment to ensure that the most important part of Moto Mind is being taken care of. That part would be you, the reader. Me filling up this blog with content that none of you need or care about would put me on the fast track to having my own online diary! I don’t need a diary for my mental health, I have plenty of fast motorcycles to ride to keep me sane.

What I do want is to create a dialogue between you, my readers, and myself so that I can better serve your needs and interests when it comes to your bikes. Over the past four posts I’ve hit on a few topics I feel should benefit all of you. Have you gotten a chance to think about or use them? Any thoughts or tips on your end concerning warming up your engine and piston ring end gap? You guys are the most important part of this dialogue and hearing from you is the ticket to making my time here on Thumper Talk worthwhile.

Along with working in some of the content you want to see, I also want to share some of the topics I’m getting pumped to post about. On the technical side, I am going to post an in-depth look at engine balance, continue to post on successful engine building practices, and discuss the importance of keeping a log of the maintenance you perform on your engine.

In addition to the technical content I am also planning on taking you through the complete design of a single cylinder two-stroke engine. As I design I am going to explain the process, creating an open door policy on how an engine is designed and why. The two-stroke engine is one of my passions and I would like to see a resurgence of it as a viable powertrain platform for sport vehicles. My aim is to teach you how the two-stroke can be produced using a more clean and efficient design.

I hope you’re excited as I am about these upcoming topics. My aim is that this knowledge can serve you as much as it has served me. Give me a holler through the comments below and fill me in on what you want to see more of and what you want to learn about. Moto Mind is merely the sum of its readers and riders.

Hey Paul,

I am a Mechanical Engineering Undergrad student at the University of Minnesota - Twin Cities and I just got my XR600R running last night. I'm a huge forum fan and have owned many RX-7's in my 5 years of having a driver's license. Because of that I'm a huge 2-stroke fan as well since the Wankel Rotary Engine is basically the most successful (in my opinion) commercialized engine used in the drivetrain of a vehicle. They are my 4-wheeled passion and I've always loved bikes as well. I'm a newer forum member and probably your newest subscriber but I do enjoy reading your entries and look forward to your future posts! I guess I'd love to hear what you get to do for a job every day as a topic - being an inspiring ME and all. That's more selfish though, and most of the time people want to be very mysterious and informal on forums which I understand. [i wrote that before reading your "Who the Heck is Paul Olesen?" post - never mind about that!]

 

I'd be curious on reading you tackle the topics of:

Non-oxy fuel in bikes - pros and cons

Picking the correct oil weight for your riding and location

Things to check for in the powertrain when purchasing a used bike

 

Those are just 3 right off the top of my head. Thanks for the posts and I look forward to reading your entries in the future!

I've put about 104 hours on the only injected two stroke in production (motorcycle).

I'll have to say it has worked extremely well.

I understand the mains are lubricated by the transmission oil- perhaps one reason they recommend 110:1 ( I run 100:1)

The light weigh (163lb) and minimal components all fit into a great package.

Hi Austin,

Thank you for your suggestions on future blog post topics!  You have some great ideas for future posts and I will try and work them in in a timely manner.  Congrats on getting your XR600R running and I hope you enjoy riding it! I have a lot of friends that love RX-7's however I've never owned one myself but I'm sure they would be a fun ride to have.

Hi Mark,

 

Thanks for sharing your experience with your injected two-stroke.  I'm curious as to which one you have as well?  Once you separate fuel and oil it is surprising how little oil it takes to lubricate the top end!  I'm glad to hear you like the bike and hope one day there will be more options out there for two-stroke fans and folks that cherish a good power/weight ratio.

Cool stuff - I am a huge 2 stroke fan myself.  I believe the future is injected 2 strokes - can't beat the lightweight/low maintenance of 2 strokes!

So you plan on bringing some Thiel/Overmars RSA love to the TT common man? I like it.

As for your engine do you still plan on a custom primary drive and driven gear? Assuming you are keeping the engine square I would think a cr500 primary would work out. Its spaced for a 79mm stroke, is already 2.5:1 and fits the 450f transmission (basket)

I'll leave the RSA love to Mr. Thiel and Mr. Overmars however I'll do what I can to share what I know about 250cc singles, designing parts, fuel injection, oil injection, and using simulation tools to design an engine.  I have the utmost respect for Mr. Thiel and Mr. Overmars and in fact consider them to be a couple of my idols. The amount of quality info they've shared is impressive and hopefully one day I can do the same.

Thanks for pointing out the CR500 primary gear situation.  I wasn't aware that it was a direct swap with the CRF450 basket.  If that is the case then it might be possible to use the existing parts.
