I know this is a very, very old post, but I'm curious about how it turned out. I don't see a PCV available on Dynojet's site -- did they produce a PCV for the RX3 at any point?

Or, for that matter, is there any fuel tuner available from any of the manufacturers?

EJK in Montana do a unit for the AJP PR5 using a Delphi EFI system and NC250 engine
That’s worth looking into?!

Hi guys!

Since 2018 haven´t my RX3 anymore: sold it only to move on towards a Benelli TRK 502 (500cc, twin cylinder, EFI, amazing Givi case set), so now came back here just to say thanks again to SpudRider and all the other amazing guys who shared their experiences and good advices with us on this thread!

Also wanna to share a Youtube video (Spanish audio, sorry) on wich I discuss all the pros and cons discovered on my RX3 (2016 carbureted version) after 2 years and 14,000mi of riding through the argentinean Patagonia roads:

Best regards,

Juan Carlos Martins.

I moved to Rx3 as an entry level ADV motorcycle soon to realize any heavier than this ... I would not be able to handle, since we have next to none [ road] here in Himalaya as we have land slides almost all the time.

Our mountains are all soil and less rocky , more of a mud and gravel as this mountain range is relatively new if we compare them to rocky mountains like alpines.

so ADV bikes are not very effective but it gave me a good head start... I moved to a 450cc ASIA WING and it was very uncomfortable.

during COVID I start to keep my eyes on PitsPro GPX450R and now arranging that to shred some Himalayan mountain soil..

In Any case it was the most reliable, bullet proof EFI pocket ADV bike which gave me a very good start.

Guys here in Pakistan we got the latest variant of Rx3 .. its Head and Sound of engine is different although its heat range has been increased... it stays at 3 points and when we stuck in traffic it goes to 4 points, even start blinking. any suggestion if we get cooler Thermostat valve to keep it cool a bit... old had 70c thermo whereas latest has 80 degree thermostat valve

Hi mate!

Can´t remember the setpoint nor have records of my RX-3 (2016) motorcycle thermostat; only have a picture ot the cooling fans switch (it was 93°C ON).
Based on your comments sounds good to replace the 80°C unit for a lower rating one, i.e. 70°C, in order to solve the overheating issue.
Before doing that you could verify if the actual unit is properly seated (some people had found them mounted backwards); if you have or can grab a multimeter with a temperature probe would be nice to check if it is working properly when submerged on a hot water bath at you home kitchen.

Regards.

Generally speaking, unless the thermostat is defective or incorrectly installed, changing it to a lower temperature one will not affect an overheating problem. If your engine is running a bit hot at 110c it does not matter if your thermostat opened at a more correct 90c or cooler 70c one. Some folks have been fooled into thinking a cooler thermostat helped them but it's normally that they have removed one that was faulty and anything would have worked better.

So yes, changing the thermostat to another CORRECT one might help but no need to change to a different temperature one.
