Today I bought this stuff: And I used it! I had to improvise a drain pan because I just moved house DON'T JUDGE ME  World's greatest funnel, that tip extends a further three inches or so into the engine.  Took the wheel off to find this:  Which explains why my speedo has only been working sporadically. You were right Silver...right all along!  Old fork oil had the thickness of water. I went to 20W but after riding it I realise this may have been a mistake. The bump damping is certainly there, and there's none of that squirelly wobble taking corners at speed, but now it understeers somewhat when you get on the power. I assume it's because I've effectively just increased both the compression and rebound damping at the same time and now it has too much rebound.  Caught this one mid-transform. Then did the plugs while it wasn't watching.  Now I just need to convince myself to go on the teeth-pulling adventure which is doing the tappet clearances. And buy a new radiator because it's pretty severely bent from the PO dropping it on grass; thankfully functionality isn't affected. And buy another speedo drive magnet thing

I haven't yet sat down and really studied it, but it looks like one end of the bolt is permanently attached to the little frame which holds the footpeg. Might have to buy a new one.

Finally got around to looking at the suspension settings on my STR675 this afternoon. It was set up about halfway between the "sport" and "standard" numbers in the manual, and shockingly, had the same settings on the left and right sides. Took a turn of preload and one click of compression off at the front, and a click of rebound at the rear. It still doesn't appear to notice when I sit on it (because I weigh about as much as a loaf of bread), but it's a hell of a lot more planted in turns now and the rear tyre doesn't skip as much over rough surfaces.Slavvy posted:Caught this one mid-transform. Then did the plugs while it wasn't watching. Looks like you'd have had the same issues as I have with doing plug changes on my VTR250 - front just involves moving the radiator out of the way, but the rear needs a foot-long gimcrack arrangement of extension bars and universal joints to clear the tank, frame, and cylinder?

High Protein posted:Installed the mount for my new satnav, I hope the mount will stand up to the vibrations of anything but an i4. Wish there was a way to secure the actual unit to the handlebars with a string or something just to be sure. It's lovely that to putting together the mount involves a combination of philips screws and nylock nuts, not a good combination. Also, the kit doesn't includes rings for the battery terminals. Still it's nice that the bike's lack of an actual tank (and its loosely fitting covers) makes it easy to route wires through there. Hi5 Lightning Long buddy. Speaking of which, I am in the process of prepping mine for a long (loop of America long) trip. I have discovered that the long version of the lightning has almost nothing available for hard bag mounting brackets, I may pick up some hard cases from ebay and just go to a welder to have custom mounts made up. I also need to finish painting the "tank".

I tightened my chain slack today, which was way out of spec and loose, and learned that my rear axle nut was attached with about 15ft/lbs of torque and was basically being held in place by the cotter pin. Thanks, previous owner! I guess at least whatever idiot tightened it put a cotter pin in.

Rode my bike over to my mechanics today, he took a minute to ride it and listen to the noise it was making. Said it sounds like the cam chain and it wasn't to bad. Recommended we do a valve job in 3-4k miles and hed check it then and replace it if he needed to. He told me to pull the airbox first and just make sure a throttle body boot hadn't popped loose.

Head reassembled!  Now all I need is an o-ring I forgot, and two new bolts for the intake elbow because I rounded the gently caress out of them taking them out. Next weekend should see head installation and maybe even first start of the season.

Pulled the airbox off the VFR and checked the intake boots. When I got in there I found 3 pieces of sandpaper  underneath the airbox. I'm not sure what they were doing in there, but after pulling them out some of the noise I was hearing seems to have gone away. I still hear the chain noise, but there was a secondary "flapping" noise that was what sounded so bad. I think the sandpaper was the cause. They varied in size, but the biggest was about 6 inches long and 3 inches wide.  Cleaned it up, reassembled it and took it for a spin. Holy crap, the lights on bright are so insanely bright. Coming from the DRZ with stock headlight it's like riding in daylight.

I did a tank/tins/plastics-only wash and wax. First time I've waxed the Enfield since I've owned it (2009), and first waxing after painting the 1979 CB650. Why the hell haven't I done this before? It's amazing

Just got my bike into the garage after having it shipped from OH to NC (which somehow was cheaper than trailering it myself.)   It's a little dirty from being driven through my backyard to get to the trailer on Monday. Seriously looking forward to be riding in an area with so many amazing roads as this.

I located the problem with my engine!  Strangely, the cylinder bores are completely fine. Glassy smooth with zero scoring. I might still go over .25mm but all they really need is a hone. I guess all the metal chunks from the exploding piston got sucked down the hole instead of rattling around and chewing up the bores? Also, the right-side camshaft support bearing is spun (completely exploded), and the right cylinder cams are scored and chewed up. Oil starvation in the head, I would expect, but (1) why then is it only happening on one half (the left side looks completely normal) and (2) why is there a hole in my piston?

Either something got sucked in (check your throttle plate screws), or you're running lean.

We had a '76 CB750 in the shop recently that had been run low on oil for some unknown period of time and caused similar damage. No piston holes, but the left side of the camshaft was hosed up on all the working surfaces. Cam towers, cam bearing surfaces, lobes. Right side of cam and the rest of the engine was just fine. No blockages, just run low on oil enough to produce low pressure.

The old shop guy here also suggested that it could have been a stuck valve that caused the hole, especially since you can see it's semi-circular. What causes a stuck valve? And if that's the case, why do the valves themselves look fine (caked with oil and carbon, but apparently seated properly and not bent or chipped) and why would it happen on the side that seems to have kept its oil? Right side: clean piston, clean valves, completely shredded camshaft bearing, scored cams, scored tappets. One is worn so badly that the eccentric barely works any more. Left side: hole in the piston, carbonized valves, completely clean camshaft bearing, glassy smooth cams and tappets. Minimum list of replacement parts: 2x pistons and rings, 1x camshaft, 1x camshaft bearing, 2x tappets, plus the tensioner rubber is all shredded and should be replaced.

^^^ Yeah, it looks like that but not quite as bad. Scratched up and rough to the touch but not outright grooved. Well yeah, but the engine still ran for 30 miles after losing the left cylinder, and I don't recall it ever locking up -- there were the sudden losses of power but the rear wheel didn't stop or anything. You're saying that the camshaft seized just enough to jam the valves on one stroke and punch a hole in the piston, then broke loose and kept spinning? I didn't realize that a single strike could do so much damage... Sagebrush fucked around with this message at 04:10 on Mar 9, 2013 |

The scoring on the top of the piston suggests that something rattled around in there for a bit at least. I dont think thats valves since the hole is basically in the center of the piston, and you can see the reliefs towards the front and back of the piston, where the valves actually are, in the head. Thats not synonymous with a lean burn through either, as those tend to look like someone sandblasted a hole in the piston. My guess is you either sucked something in, or lost a chunk of sparkplug maybe?

Rev. Dr. Moses P. Lester posted:Seen an old BMW with sticky valves due to heavy buildup of [pre-ethanol] gas varnish on the valves from sitting for years with a slightly leaky petcock and a slightly leaky float valve and a plugged overflow on the carb so that the excess gas drizzled into the intake. The result was hard starting and more valve noise than normal. My friends Rebel 250 has varnish on one of the valves from being parked on an incline then sitting in a garage for 3 years. I just sprayed some seafoam in there and hit it with the high pressure air nozzle and it came off.
