I found the BLWUR manual and it says to tighten the treshold screws to raise the treshold. I will try to raise the treshold and lower the enrichment pressure by lifting it level with the WUR first. If that does not get a nicer AF curve I will try to use a pressure relief valve on the hose and remove the treshold screws too to get max fuel for top end.

I will report back later. Thanks JFairman.


Pulling the enr. cyl. level with the WUR and turning the 3 screws down some, did not help with high rpm AF.
4th gear 3000rpm looked a lot better but next I will try the 3 screws removed for MAX fuel. I have a gut feeling it will still be lean though up high and stupidly rich at 3000rpm (but that can be dialed out later with some kind of valve).
