BS6/Euro5 477 now possible - Racedynamics released the new V.4 Powertronic for the Hima

Leh is actually at 3500m, not 2500m as I previously mentioned.

The power loss of an internal combustion engine at 11,500 feet is approximately 34.5%.

that explains a lot

Exactly.

Best case scenario: it would feel like a stock Hima at sea level...

So it was designed to " Go around the Himalayas" not, " Over them" :unsure: Built with the Tunnels in mind.
 
@Sasa: Back to zero elevation and running on long and relatively free highways I noticed that the bike can accelerate very quickly up to 5000rpm, then struggles and finally can not go beyond 5800. I can not reach 120 kmh although it is easy to reach 110 quickly. what is going on with the mapping?
General power is much higher than a 411 would have - my guess is close to the 27-29HP that where measured a while ago by Dool - but with the caveat mentioned above.
 
Head!, mine goes to 7500RPM and has a different head :cool:
But seriously your Cam timing is out, unless by some stroke of luck, nothing personal it just so happens all Himalayans have the same fault.
I still can not offer a solution:(
 
Fixed most quirks by generously adding fuel all over the map - map2 has now 15 points added from 500 to 7000rpm flat.
Bike runs very nice after a very short period when cold (like 2-3 minutes) but even then it runs OK, just not optimal.

here are the current fuel mapping, didnt change anything on the spark front:

(remember: bike is now 500cc)

Sam please how can I get the map you are using? I have a Hima Bs6 with ONX Racing comshaft, full exhaust and sports air filter, and I'm installing a PT V4 but I can't get a more or less map
 
ok thanks but for us Brazilians it is financially unfeasible to buy a 477 kit abroad. With a lot of effort I got a camshaft from ONX Racing and the Powertronic which costs something around 25% of the value of my Hima... but it's ok if your rules are these, I had thought that "forums" were for exchanging information and experiences and not focused on "business" and technical support for specific products... thanks, God bless you.
 
There are forums who ask their members for contributions or place advertising all over the place. That's OK of course, forums are work intensive and have license costs to boot. Then there are company specific forums where those costs are covered by the company. Ours is one of these. We do provide answers to questions from "none customers" all the time, just not if they are specifically targeted at products we sell and which have been purchased elsewhere by the questioner.
Additionally it is bad form to just crash a forum, no introduction, no previous interactions at all, no reading of the relevant sections that explain how this forum works - just the usual entitlement of "you got to help me poor bastard". That is not working here.
