I love my fazer to bits, and think it's possibly, no, definitely, the best all rounder ever built. But that bloody exup.......anyhoo, today the missus has an eye test in the heart of Bristol. Living in the Forest of Dean and Knowing the traffic will be horrendous from the Severn bridge onwards I take her in on the thou, with its freshly greased exup valve. In Chepstow I get the bloody 7k fault! Anyhoo, it was intermittent so onwards to Bristol, and I park on the pavement and get the toolkit out right outside the opticians. At least I can play the breakdown card if a traffic warden shows up. By now the fault is happening constantly, and it's ok in the city so I know the valve is stuck in the closed position. I whip the pulley of the valve and try it, valve turns easily and smoothly, so put it back on and slacken the cables a bit, reasoning that I've over tightened them perhaps, even though it's done probably 200 miles since I last adjusted them. No difference, so I take the pulley off again and check to see if it moves around hanging loose. It doesn't, both when I'm revving the bike and when I kill it with the kill switch. So all back together, and head home with 7k fault going all the way, and get there wit h about an hours daylight left to check it out. Again pulley off and check, no movement. So tank up, left hand infill and fitting bracket ( the one with the reg/rec fitted to it) removed to give me a bit of access. I'm thinking the cables are frayed internally and locking up, but pulling on them near the servo pulley with needle nosed pliers they seem ok. I pull them back up through the outer sleeve to give them both an inch of play near the servo and try it again. Servo not working! Wasn't expecting that :-( anyhoo, there's a slot in the left hand side of the servo pulley, I can just about reach thru with a slotted screwdriver and put it in the slot and see if there's any movement in the pulley. It's stuck but suddenly gives a little bit. I start the bike and bingo, it's turning ok, and no 7k fault. I spray loads of wd40 into the servo pulley shaft as best I can, reconnect the pulley on the valve, and take up the slack in the cables, and try it again. It's all working ok. Buggered if I know...I've not used the bike for a couple weeks while I've been away working, is it conceivable it seized up in that time. Have sprayed loads more wd40 around the servo pulley and will give it 20 or 30 miles in the morning to see if it's behaving...
