Hi all an update on the state of play with my re jetting process
well to any one who has not done this its definatley is a process and you get very proficiant at taking your carbs on and of and taking them apart.
I just received the new air pilot jets i ordered.
I got three in a progressive size going up in increments of 2.5 they are 135 137.5 and 140
stock was a 130.
My plugs prior to fitting a new air pilot was still running rich after reducing the main jet to 127.5 there was an improvement from stock 132.5 but not enough,
I fitted the new air pilot 137.5 decided this may be better result than the 135 and re fitted the air filters as air pilot jets can be changed without having to take the carbs off the engine.
I attempted to start the bike after a few goes, i increased the idle screw and it started but ran lumpy, I then had to dial out the mixture screws about 1/4 turn to get a good idle which was about 1500rpm i reduced the idle screw to about an idle speed of 1100 which means the mixture had been weakend by changing the airpilot. I bliped the throttle and took the revs up no pops or back fire test run tomorrow
