Tx 4 racing

[atvmxr]

First race of our series was Saturday, on my 44 bday.  They have vintage and trike classes.   We had 6 Rs and a banshee.  Next race should have 3-4 more Rs that weren’t quite ready. 
4 trikes, 2 atc Rs,  a Tri z, and a 250sx

Dave Moore was out there helping guys with tunes and stuff.   Had his sponsored rider out there on a new motor they are developing.  For some reason they didn’t put a desert tank on and had to stop for fuel.  At which I passed his rider  for the lead

Dave came over to congratulate me and tell me “you rode the shot out of that R!”

4 ~six mile loops in under a hour.  I had some of the fastest lap times of all classes besides the pros

Very cool.  Thanks for sharing.  Congratulations

I'm 40 and falling apart. No way could I run a race in the shape I am in lol

Happy Birthday.  I’ve never raced.  Too old to start now lol.

Cool to see DMR out there with you guys.  I met Dave and his sponsored rider last year.

I’m curious about the new MX cylinder in development.

Croat, are you in Texas?  on any of the "R" Fb pages?

Anyway, I have a ROWDY Pro-X 310 (295cc) that was ported by Jerry Hall and it has been on Dave's dyno and the new "development" cylinder Dave is working on makes 2-3 more HP than my cylinder everywhere on the curve.. Displacement is comparable. Lot of front side to the hp curve. Broad power. He'll give more details soon as its almost done.

Ajbuilder250r, I’m in Ohio.  I was on many R FB pages (too many that I have since deleted myself from most of them….still on a few select ones).

What were the other components that were tested with my cylinder...pipe, head, carb, reed, ignition curve, intake ??   I have built a lot of different engine packages for the Pro-x 310 and ESR 310 cylinders.  I have seen peak power range from low 40s to low 60s with a zillion different shape power curves because many cylinders may have one or more components in the package that is wrong.

Unfortunately I am not. I am more of an unsocial media person.

Jerry, it is setup with a cone-shaped intake similar to the LED style that Dave made with a large K&N filter on it. PWK 39mm, V-Force 3 reeds, TRX-5 inframe (small headpipe) and ESR silencer. OEM ignition with +4 degrees of timing advance. It's a BEAST.  Dave doesn't think you left ANY power on the table with that cylinder. Masterfully developed and ported. The other cylinder I mentioned is apples to oranges in the comparison. It is not a Pro-X or and ESR cylinder, it has different and more transfer ports, etc.  We think you NAILED it. LOVE this cylinder. If you see something in the setup you don't like, I got my ears on.. You developed it. I got it secondhand out of Arizona.  It ran with 350s, 363s and 380s sand dragging at the dunes last trip...

I put the unported stock cylinder in it for the race with the new DMR coolhead and made it more mild for the woods, great setup for XC woods
