Been sick as a dog and still not feeling great, but here's the latest. Air cleaner picture above shows the two different types that were on the bikes when I bought them. The one on the right has "XS" stamped in rubber and the chrome back cover, the other one has the lip I was told about in an earlier post but no markings as to who made it.
I installed the pamco kit and set the timing, didn' t seem to make any difference. Got a new set of plugs and now they look lean, bumped the main to 132.5 and the needle to position 4. Still lean but seems a little better. This is all done in my garage slowly increasing throttle and listening to motor wind up. Changed to 135 main and plug color looks better but still breaking up some. I compared the adjustable needle to a stock one and the adjustable one is much longer. In the third position starting from the top down, it is 4mm longer than stock. If I go down to the sixth position I am still 1 mm longer than stock. Starting to think these are the wrong needles, I thought the major problem with BS34's was a lean issue. These needles would only make it leaner in my opinion, the taper seems to be similar. I put in stock needle and it sounded better, not perfect but better. Will have to clean up a bit and replace seat and tank for a test ride to verify improvement.
I think the cam being in backwards caused my running rich issue causing me to change main jet size, after swapping the cam around I have been able to return to the 135 main jet and the plug reads fine.
Main jet 135. Stock needle from top of clip to tip 50mm
Pilot jet 42.5. Adjustable needle from top of clip. Pos 1- 56mm. Pos 4- 53mm
Air jet 135. To tip. Pos 2- 55mm. Pos 5- 52mm
Needle jet Y-0. Pos 3- 54mm Pos 6- 51mm.
Will try to test ride tomorrow depending on how I feel, any comments or advise welcome.
