RZ/RD 350 & Misc. 2-Stroke Tech BBS

Thanks to Jon and Waltmilt for your input. You guys are correct. I have also heard that idiom and have had it happen to me personally. So, after running this motor for 8000 miles on the street, and then making over 200 runs down the track, the compression dropped 1 psi on the Left cylinder, and 3 ps...

It was a long, rather somber trip home, and I had plenty of time to reflect on the past race season. I assumed that I didn’t hurt the motor. And I assumed that the RZ had a charging issue. After getting the RZ back to the shop and charging the battery, I started the bike and discovered that the cha...

Thanks to Ken and Jon, and the other folks out there, for following along on the adventure. It was a somewhat disappointing season, because I’m pretty competitive, maybe overly competitive. When I enter a competition, I want to win, and show everyone that I can do this better than them. I have no pr...

Crank winding is when the ignition timing on the right cylinder is firing to early due to there being a delay induced by crank twist under load. Hi Kenny. Thanks for the information. I'm running the Zeeltronic PDCI-D22 race ignition and it does not allow me to advance or retard idividual cylinders ...

It was a long, rather somber trip home, and I had plenty of time to reflect on the past race season. I’ll give you the quick recap, and then I’ll stfu, and quit wasting your time. I assumed that I didn’t hurt the motor. And I assumed that the RZ had a charging issue. I was upset that, for the first ...

After showing my time slip to everybody within shouting distance, I put 3 liters of fuel in the bike, so that it was ready for the Elimination rounds. Then I sat down in the shade, and went back to the task of picking a Dial-in Time. And this last run was not as helpful as I had hoped it would be. O...

While I was thinking about the dilemma, I heard the track officials call all bikes to the staging lanes, for an open Test and Tune session. When I heard the announcement, I was confused, because the bikes only had 1 Test and Tune scheduled, and I had already participated. As I thought about it, it o...

So, getting back to where I was, evaluating my runs and picking a Dial-in Time. I made 4 decent/average runs, and had times of 12.62, 12.68, 12.73, and 12.62 seconds. My 2 quickest times were in the morning, and early afternoon. My 2 slowest times were in the late afternoon, when the air was hotter....

Test and Tune was over, it was time to pick a Dial-in Time for the Elimination rounds, and it appears that this thread is heading off on a short tangent. I’ll start this digression by giving you my opinion and, please remember, it’s worth exactly what you paid for it. The main objective in Bracket R...

Hey folks, I apologize for the delay in getting to the conclusion of this saga. But, life has a way of interfering with my plans and I’ve had places to go, people to see, and thing to do. When I got home from work today, my social director informed me that I had no plans for tonight, so I sat down t...

With the EGT it sounds like you have crank winding which can be compensated for in some programmable ignitions like the Ignitech Kenny. Thanks for the input. It may be because I live on the opposite side of the pond, but I haven’t heard the term crank winding, and I’m not sure I understand what you...

After Qualifying was over, and the timing lights were shut down, I actually did grab a beer and sit down in the shade. It had been a long, hot, eventful, 10 hour day. I needed some time to unwind and let it all sink in. I did check the EGT’s after my second Street run and they were lower than the EG...

Saturday, Sept. 16/23 – CMDRA Race #6 – Medicine Hat, AB (cont.) As I recall, when I last posted, and left everyone hanging, I was hell bent on trying to seize an RZ engine, at 100 mph. ...I get to the front of the staging line, and they wave me onto the track. ...Don’t do this ... This is a bad id...

[smilie=dunno.gif] [smilie=dunno.gif] I discovered the intake leak at noon, and I pulled into the staging lanes at 3:00 pm. ... I already had a ‘plan’ on how to prevent the engine from melting down. :smt005 I’ve made 40+ runs on the 1/8 mile track in Rimby (elevation 930 meters, 3050 feet), and my m...

To begin with, I need to correct an error that I made in my last post. For now, I’ll just say that the RZ seems pretty happy when the maximum EGT is between 650*C and 660*C, at the end of the 1/4 mile. It usually runs in this range at most of the tracks. And those numbers were wrong. The previously ...
