I’m starting a new thread here because this is another issue and the other thread is getting to long and losing focus…
Update: I have blown my piston and ring due to my engine running to lean. Now I have a little pressure more pressure after a few fixes and the bike is running again. I have a Dell Orto SHA 14/14… StrayDawg told me my jetting was way too low for where I live..(Thanks Dawg) I was cheap and tried to drill my Jet to .080 because I had the micro drill bits. It broke in side it and I had to enlarge it to .091. It started but it was running horrible and was super Rich.. The oil was coming out between the engine and exhaust and it was obvious it was rich…
I bought an assortment of new jets and started with 78. It started right up and sounded better. On the bench it wasn’t so bad and sounded strong after a bog or two.. I took it out warmed her up again and it had no bottom end but did speed up. It was hanging onto the RPM’s after the full throttle tests so I took it home and changed to the 74. It now took about 4-5 pulls but started and sounded good after some throttle adjusting.. I took it out again, almost seemed like it didn’t want to start. After about 10 pulls it got going and sounded really good. I rode it around a little at low speeds but did try to gun it a few times.. Still some loss of power from what I had before but its running pretty good and fast for 125 PSI.. I was thinking if I went down one more to 73 I might find the sweet spot..
Now… I just took out the plug and its gray and dry…. Still super lean…. Am I missing something? Do I need to change the needle or something… Why am I still so dry? I’m running 25:1 Lucas Semi Synthetic and 91 octane. I downloaded the manual for the SHA so time to start digging in but figured I post my problems first. Should have read that before I went crazy but it seemed to be running so good… Any tuning or life saving techniques would be much appreciated!!! Thanks to EPR, StrayDawg and CAM for all the help you’ve given me… I appreciate every bit of it!!!
That turned out long… Sorry!
Cheers!
