. That's cool but i think thats its not good to engine . When i make a litle bit longer a exhaust system (you can see on this movie http://www.youtube.com/watch?feature...83U-NhW8#t=44s )problem was gone . But i think engine dont have a power .I dont make a dyno run . And my sp1 take lot o fuel 70mil and i have yellow light to tank . So what can i do with this ?
I dont have something like this in my bike , i think so .
An Earlier owner start at my bike in the race . So i have k%n filter . Clean snorkel without valve . And Leo vince exhaust . And could make some changes in injection system . Becouse when I give the full throtle and release throtle , and at this same time turn off the injection with the red button .There is no back fire .
I dont think the europe model had the pair system(here in NZ we got the europe model and mine does not have pair system), check the fuel pressure regulator.
According to the UK service manual, the Euro E, ED, and F types did.
The U models shipped to Australia and NZ did not.
I've seen photos of Aussy valve covers and they only had unfinished castings for PAIR valves.
When I had my Two Brothers exhausts installed, I had a lot of pops when I closed the throttle like dear Sub said above. After a while i installed the PCIII usb with Dyno's map for 2bros and all the pops just gone. Even with the flapper fully on permanently......
