I held off for a couple tanks before jumping to conclusions.
Haven't had much time this spring to continue dialing in the bike from last fall when I first started using it.
Dreaded pulling plastic off to do the inevitable valve adjustment but I had all the symptoms, especially at the end of my long ride in spring.
Decided to drill 2 holes thru the bottom of the battery box to access the top cap and was able to make that adjustment on the intake valve.
Only undone the 2 farthest back screws on the black bottom panel to drop it from the back and let it hang from the front.
Got the exhaust valve from there. However I left that one loose at about 6 - 7 thou. A little ticky but the results have proved that is better than too tight.
Biggest time saver was not going thru this timing business.
I thought about it. All I want to see is the valve in its closed position. I dont really care what cycle its in.
So I slowly cycled the engine tapping on the starter with the battery hooked up until I saw the valve closing. Repeated a couple times to make sure I was in a closed cycle when adjusting each valve.
When finished the thing started within a second and the idle went over 3 grand.
I had been over compensating the idle as my performance detoriated since new.
Grabbed a handy minature rachet wrench with Phillips bit in it since this is the only way to adjust the idle on the carb I replaced my original with - the idle screw is now horizontal facing the back of the bike, not vertical like the original.
Man I had to have had that screw halfway out.
Got the warm idle down just below clutch engagement and wheel spin.
Perfect.
Has never ran so smooth and started so good. Hot and cold.
Starts the same with no stumbling.
Power is right there. Need to retry those mountain passes I've always had trouble with.
I have to admit I was at the point where I don't have the time to constantly adjust this bike and it wasn't near my expectations to begin with.
Now I love it and would buy another.
60mph with barely any throttle.
Carrying two up grades with no slow down like it had before.
Two tanks now with city stop and go walking up to traffic lights that cycle 3 times before my turn.
Plus rural 50mph half that way.
Get this.
89mpg.
I am blown away. And I verified with GPS.
I did it twice. And it feels like it. No effort to make this thing go and keep speed now.
Cant wait to do a long rural tour and I have complete confidence in 90mpg.
Different carb, fine tuning the air fuel screw, loose valve adjustment. Did the trick for me finally.
