Went to investigate what I thought might have been a hot seizure some weeks back - I put it in neutral and coasted for a few hundred yards and it came back to life fine when I put it in gear and I just carried on and have been riding it since.
But obviously it was a seizure in the making from the gudgeon pin retaining clip breaking. Classic occurance, that I had yet to experience until this point.  ____________________ CBT: 12/06/10, Theory: 22/09/10, Module 1: 09/11/10, Module 2: 19/01/11

Almot piston only 4k miles old. Used the gudeon and clips that came with it. I had to put this new one in as the old piston had a piston ring retaining pin recess into the piston allowing a ring to turn and get caught up in the exhaust port- thankfully little damage from that too.
Barrel is gouged but thankfully mostly only below the side/exhange port which is good. Might put another new piston in again. But cut the clip ends shorter to reduce likelihood of fatigue on the bend allowing the end to flex off. It's not rare for this to happen, i'm just disapointed. These sort of set backs continually seem to occur to me. Too many machines you see.  ____________________ CBT: 12/06/10, Theory: 22/09/10, Module 1: 09/11/10, Module 2: 19/01/11

Tinkering with the Old Fella's Harley...
He couldn't get it to start this morning: press the button, click, thud and then the electrics died. Sounded expensive. Of course when I lay my hands on it the bike starts perfectly fine We had a natter about this and that, then he tried it again - click, thud, dead - but at least it was decent enough to do it in my presence
Whipped the seat off to check the battery, 12.7 volts not too bad, and the bike sprang to life again So we cleaned the terminals (after a slight argument with the alarm system) and I'm pretty confident it should be fine now.
As a bonus we also discovered the source of the buzzing @2,500rpm on my GT! A lot easier when you have an extra pair of hands to prod things. Turns out it's the clock mounts, I'll order the upgraded versions from Hitchcocks. ____________________ Royal Enfield Continental GT 535, Husqvarna Vitpilen 401, Yamaha XSR700, Honda Rebel, Yamaha DT175, Suzuki SV650 (loan) Fazer 600, Keeway Superlight 125, 50cc turd scooter |

Replaced O-ring for the idle air bypass screw on the 251's BVF 30N3 carb. Idle speed was a bit up and down depending on ambient temperatures. Do need to do a tune and balance the idle fuel screw adjustment and air screw adjustment after a ride but should be fine now hopefully after doing so.  ____________________ CBT: 12/06/10, Theory: 22/09/10, Module 1: 09/11/10, Module 2: 19/01/11
