There is an entire turnkey wankel kart for sale on ebay.August 22, 2013 at 10:13 pm #7834
Contact Richard Blackburn in the UK, he has a shop over there, XratedKarting and he handles Aixros and I know he has used ones from time to time. He does alot with the Aixro race series they have over there. Whenever I need something or have a question, he answers it and will take the time to send emails with pictures, etc to make sure I understand everything….he knows his stuff and keeps a good inventory of parts. His personal email address is email@example.com Are you wanting to get an Aixro so you can come out and play in our new series? First race will be September 21st in Ocala, you may be pushing it, but he can send you a ready to bolt on, hook up the radiator and go motor. I have a few gears you can borrow to get you started.

I might be a little leary of that kart, he’s been trying to sell it for over 6 months now (at least I have seen it posted that long). Don’t know anything about it, but being an ‘O8 chassis, the motor may be as well and they have done some updates to the motor since then. I have read differing opinions on porting the Aixro and boosting the hp, may be sacrificing the nice power curve and reliability of a stock motor. Not telling you to not explore it, just do your homework and ask alot of questions about it if you do. From what I understand with all vehicles, a ceramic pipe holds the heat in and I don’t think I would want to be holding any heat into a pipe that is having 1600 degree exhaust pumped into it.August 23, 2013 at 6:00 am #7837
I would love to find a nice used 3rd Gen Tag unit. They have been totally updated. Brad at Engines for Racing says they are prone to have problems as he sells them. He recommended the Rubig Mega-R01 650CC monter kit. Its about $2000.00 cheaper and appears to be a bit quicker.
Has anybody got any feedback on it?August 24, 2013 at 7:05 am #7909
The Rubig is not faster than the Aixro, at least not from the videos I have seen. Search youtube and the are a few videos of the Rubig running against shifters and the Aixro. It appears that the Rubig is a monster when it comes to low end power and has alot of pull out of the corners, but is not as fast on top end. The videos I have seen show the Rubig opening up the slightest of gap out of a low speed corner, but all the karts either closed the gap and were on it’s bumper or pulled even with it or passed it in the straights. Never seen one in person.
Richard said he has a Aixro with only 4 hours on it for sale for $5,000. That included carb, pipe, PVL ignition, ceramic bearings/seals, engine mounts nad new Freeline radiator. Pretty much a bolt on and go package.August 25, 2013 at 5:11 am #7964
I looked into the Rubig and bought an Aixro. I think the Rubig is going to be very similar to a CR 500 in a TAG engine. It’s big and heavy with a low RPM range It’s probably got great low end grunt but lacks top end HP. I also think the overall production numbers are very low. I would be concerned about whether or not they will stay current or become obsolete.
The Aixro has a lot of power but the thing that makes the Aixro different is the way it delivers the power and the fact that it does it in a compact unit that isn’t very heavy. The Aixro drives like it has no power band. After the clutch engages you have torque regardless of the throttle position. It’s the polar opposite of a 2 stroke and better than a 4 stroke at giving the driver precise control of power output. It’s also much smoother than a piston engine.

Hey Brian have Richard give me a call 407-222- nine,five,one,five. u r awesome and thanks. I was wondering about the reliability of the XR50???August 25, 2013 at 10:55 am #7982
Reliability is great and a true 100 hrs between service if it is driven according to the manual and even then, the service is not much. Mine is over with Richard being serviced right now. The aixro only has two issues, one if it is over revved and it’s a costly mistake. All the new ones come with a PVL ignition with a rev limiter, so over revving it is taken out of the equation. The second issue is if you run it at WOT for more than 10-12 seconds, but that’s never been an issue for me either. It is an engine for kart tracks, not road courses.September 8, 2013 at 9:10 pm #9370
What happens after 12 seconds, does it get too hot?

It has to do with a bearing lubrication issue. I don’t know if it’s due to the heat generated or the rpm’s, but the only lubrication is via the fuel/oil mixture. I run two temp sensors, one for the water and one for the main bearing temp. During a long WOT run, you can see the bearing temp climb and as soon as you lift and the rpm’s fall, so does the bearing temp. When geared correctly, it’s never been an issue for me on a purpose built kart track…..but they do warn it could be a potential issue in a road course.
