So I took off the tank, drained the V2 race fuel and put in some brand new NGK BR9ECM's
I had a gut feeling about the RC Valves and in danger of adding to many variables to the test, took off the side fairing to check the power valves adjustment being careful to check in on exactly how to do it (thank you Andy) AND catching up on MotoGP Practice
started it up with the fuel left in the bowls...let it rev to 2000k and killed it when the RC Valve Pulley moved to the HI point.....note these don't have the pointer that the original has but you can tell where it should be.
they were slightly out but now are spot on...
I put on the four holer airbox lid and double checked the carbs are sync'd ok. looks good.
Took it out....rear cylinder acting normal- front again not happy. Felt like it was running on 1 cylinder all the way didn't reach any exciting power band. Quick u-turn home. Took off the tank and removed the airbox lid...simply because it was the easiest change to make.
It was MUCH better but again didn't reach power band.....front cylinder still practically dead. OK- just to be sure may I ask: which carb takes care of which cylinder. I think it's LEFT carb for the FRONT...am I right?
I think it was a mistake to adjust the power valves in all this- so going to double check those again and then I'm going to take the carbs off and I may send them to MuttsNutts to give them a good clean and going over- partly because it will give me a break from the NSR and allow me to fix some of my broken bikes of which there are TOO MANY. When I get them back I will return to standard jetting. who knows. that might be the answer. FIRST will attempt to talk to TYGA again about jetting. I've tried before but got no response. Since then however I think I have a more direct contact.
