Thankfully the drive face is aluminum and the crankshaft is steel. I initially had a panic attack when I thought the crankshaft splines wore down, but they were just caked in a shitload of powdered aluminum

I've seen a burgman 400 destroy the crank splines (steel) thanks to a loose variator nut making the variator cones flop around exactly like that. I suspect the horsepower/weight difference contributed though, plus the guy just ignoring the noise instead of stopping and checking the way you did.

Put a bolt back in that was missing when I bought it. Going to have to take it back out and loctite it when I find my tube of loctite. Destroyed a 3/8 to 1/4 adapter in the process. Then I rode the big bastard through the mountains. Got snowed on a tad. Thighs are cold. Think I may have a viciously tight-spotted chain, there's a noticeable and rhythmic *hitch* when I'm off power. Either that or a wheel bearing is hosed. Goddamn it I just replaced the chain and sprockets on my old bike.

Set the chain tension. The sssa made that an easy job. Set the suspension. No compression damping adjustment possible on the Futura. Disappointing. I guess I need to get Falco R forks and... what legitimate adjustable rear shocks work on a RST mille?

You may need to force open the rear pulley and ziptie the belt in such a way that it stays open or something like that. The crucial point is that when the front pulley nut tightens down, it must tighten down on the metal pulley halves and spacers, and NOT tighten down on the belt at all. If the front pulley halves are squeezing the belt when you tighten that nut, bad things will happen such as was posted above.

That is probably exactly what happened. I tried to get the belt as loose as possible but I probably didn't do it well enough.

Rode for a couple hours today, got back and the entire right side was covered in oil, as well as my leg and boot: There was a little pool just below the spring, where I guess it has been dripping off of it. Had a little look around, no idea where it's come from yet.

Picked up some kinda puncture on the rear tire on my nx250. Spotted it just dropping off the trash after leaving the cabin. Filled it up with foam, grabbed the manual foot pump at the cabin and set it correct pressure(1.5 bars) and rode the 100 miles home cheching the tire pressure periodically. It had dropped from 1.50 bar to 0.6 after the first 20 miles, but after i hit it with a little more foam + filled it back up to 1.5 it stayed there for the rest of the trip. Didn't see any nails it it or the like so will be interesting to see where the leak is. I thiink it might have been that bigger than expected rock at the edge of one of the river crossings just near the cabin the day before. Got a new tube waiting for tonight.

 Went to my friend's house to replace my chain and sprocket. Did you know you have to clean and oil chains!? For the first ten thousand miles of my bike, I didn't!  The mechanic has a "tree of shame" where he hangs badly treated parts like condemned men. We added mine to the list and then looked over the offerings.  Of course, my sprocket isn't the worst thing hanging from that tree. This owner's complaint? "The bike doesn't go above 30."  My new chain and sprocket. I forgot they were that color

I'll have you know I have a machine that puts air in my tires and I checked it...some weeks ago. As for the oil, I already learned about that, in the form of a DR650 I rode in for a check up because it was "squeaking": No oil, and no lobes on the cam shaft neither. Actually, I forgot to take a picture of it, but when I was done putting my bike back together after changing the chain and sprocket (and spark plug and air filter) I have a couple of bolts left over; I need to take the bike apart again to see what they're for. Man that sounds awful now that I''m saying it out loud.

BOLTS LEFT OVER

You make it sound so serious, based on their design I think they're for a fairing piece that is also held by a clip and an overlap from two other fairings and the headlight. Probably. Ok I'll pull it apart after work today.

If you've never found extra bolts/screws/washers/conrods after wrenching I'd say you haven't been wrenching long enough. At least for me, it is when you don't recognize the bolts or don't have a clue where they go that you should begin to worry.

Take a piece of cardboard, punch bolts/fasteners through cardboard and use marker/pen to label where they were removed from as they come off the bike. Works better for me than trying to keep several little plastic containers full of parts from different areas of the bike separate.

Works better for me than trying to keep several little plastic containers full of parts from different areas of the bike separate. This is pro advice and beats egg cartons all day. If you have a big enough piece of card board, trace the cover/part you are taking apart 1:1 and push the fastener though at the exact location it would be on the part after cleaning it and noting next to its place if it needs loctite or anti seize. Makes assembly a breeze.

I did that cardboard thing when I was rebuilding my CL350 and it was an excellent idea. I haven't done it since because I'm lazy but yeah, do it. My favorite thing is when you get a "rebuild kit" online and it says it comes with all the parts that you need to do some job, and then you do it, and at the end there are like two unused O-rings and a copper crush washer left in the kit and you didn't take any parts like that out and you absolutely cannot figure out where they're supposed to go. So you're sitting there going insane trying to figure out if the kit just included extra parts, or if they're meant for a slightly different model, or if the DSPO hosed around with this part before and left the O-rings out, or if the exploded view in the manual is drawn incorrectly, or if you missed a step somewhere, or aaaaaaaaaaaaaaaaaaaaa

I have the opposite problem where gasket sets don't come with all the seals/gaskets and the ones that aren't included are invetiably the ones that always leak/crumble to dust. The bullshit round plug in the head of an LS650 engine is the biggest culprit: always leaking, never available. Or the problem seemingly unique to ancient hondas: the base or head gasket stud spacing isn't quite the same as the actual engine and you have to modify the gaskets.

Glanced over the sprocket covering, took the fairings off, the seats, lifted the gas tank and peered underneath. Nothing; there's nowhere for these bolts to go. Goodbye thread, I'm already dead.

I had this when I bought a barbecue last month, some extra screws of a type that weren't even in the build instructions. Best guess is it's more expensive to confirm the exact right number of components (and only the correct components) are in the pack than to merely be certain the pack contains at least everything you need.

Funnily enough I had an almost identical problem with a barbecue but instead they had given me one bolt that was 2mm bigger than all the nuts in the pack, so like the good bodger I am I just epoxied the whole thing in place. Apparently at the factory they just weight the parts bag (which is of course filled by machine) to confirm if there's enough stuff in there. If it's overweight they don't really care and just assume another bolt fell in.

The crusty old mechanic at work showed me how to make custom gaskets in about two minutes. Place sheet of gasket material over thing that needs gasket, with a couple dabs of RTV to hold it in place. Tap perimeter of design with the peen of a ball-peen hammer, and it cuts your gasket automatically, and perfectly to fit. It'll 99% transfer and perforate bolt holes, but won't cut stuff smaller than 3/8" or so.

That's about how I made an oil injection pump housing gasket out of a cereal box. Spoilers: It isn't oil tight

Yeah this works great when the seal in question isn't a non-standard diameter rubber cup or some such nonsense.

 Cut the groms legs off. I did some trail riding and the bike handled it pretty drat well, but I was bottoming out a lot. I figured I would try some thicker oil in the forks. Hit some trails after and it didn't bottom out ~as much~ but I'm going to add a little more over what the stock level was and see if it helps before I go with an even thicker oil.

There are Ohlins and Racetech spring kits for Groms that aren't ridiculously expensive (until you realize how much they cost relative to the cost of a Grom) that are supposed to work wonders. Other people just put spacers in the forks to jack up the preload

You can't use spacers with the new forks but it's not really a big deal. I'm not gonna go crazy trying to turn the thing into a dirtbike. I'll thrash on the stock stuff till it's wrecked and then look at replacing it with something better. next day edit: i added a small amount of oil and was able to sneak about 2mm of preload on the rod since there was enough thread at the end to safely raise the cap. Feels better already. GabbiLB fucked around with this message at 19:41 on Oct 8, 2017 |

Figured 20,000 miles was enough on the stock chain and sprockets. Front sprocket nut was a real pain to get off, and I managed to put another scratch in the black cheese they made the swingarm out of.

After a year and 10k flogging the daylights out of it, I sold the 690 SMC for everything I have into it, including consumables and insurance and maybe gas. New owner really appreciates every little thing that has been done to it, and even is excited about using the harlequin vinyls.  Oh yeah and I also picked up this cute little guy for a great price. The owner and I hit it off so he even gave me 4(!) VIP Patron hospitality passes to the Petite LeMans this weekend. We all had fun getting wined and dined all weekend, and enjoyed the race.  It's so cute. I even love the white 2nd gen fender. The slight red flake in the side paint looks good with the slight white flake in the fender. Great bike, though the seat is the worst seriously.
