heat cycled my new triumph engine a few times before tracking it and its a good thing I did. minor coolant leak. no biggie more alarming. the oil seal at the output shaft is leaking a good deal. the seal I can source from NAPA so not a huge threat to my upcoming weekend. slightly annoyed to have to do thus job though.

Simultaneously the best and worst 600  What's the state of the timing chain situation on these things now? I remember the oil level revision, the shorter dipstick and updated parts etc but I haven't kept up.

Even though I knew it was coming I was surprised the crash happened there, didn't seem like you were being too aggressive but you were braking harder than the guy in front of you. Looks cold and possibly damp though. Beautiful looking track, where is that?

There was a very clear reason, at least on my phone it looks like he didn't reduce brake pressure enough as he added lean angle and the cold tyre didn't want to cooperate. Used up all the grips.

Warmers are one of those things that everyone is convinced they need but very few people actually need. They aren't mandatory if you have slicks, as long as the slicks can be brought up to temperature without crashing the bike. Sometimes it is impossible to put enough load on the tyres to get heat in them because they haven't got the grip to sustain the load, this is generally referred to as being up poo poo creek.

They basically let you get one extra full pace (for me) lap per track day session and for someone like me it's not yet worth the expense

GriszledMelkaba posted:They basically let you get one extra full pace (for me) lap per track day session and for someone like me it's not yet worth the expense My anecdotal experience is that you don't really need them if the race has a warmup lap, and not at all if you're just tracking unless you're on something really fast and serious in which case you aren't reading this. At least in post classics it seems like the old men can't be bothered with them and just do an aggressive warmup, the younger more techy dudes gently caress around with them but it doesn't seem to alter the results. Generally the track day dudes that roll up with an rsv4 and warmers and a five thousand dollar suit elicit eyerolls and circulate around at the back getting passed by hyosung cup guys doing training.

I got bored and ordered a bunch of parts for the Scrambler. It started as just wanting to make the bike a bit more subtle, so I got clip ons with a 1.5" rise and a set of Motogadget bar end mirrors, the non-glass ones that are just polished aluminum. I figured I might as well change out the blinkers, since I hate the stock ones, and found that Ducati actually makes a low-profile set similar to the Motogadget ones, but that I wouldn't have to custom fabricate a bracket for. I got them for the fronts first to ensure they were bright enough, and next I'll get a set for the rear. I also bought a set of carbon fiber tank fenders, and I had intended to put an oldschool Ducati badge on there but that screw in the middle is in an extremely stupid place, and the fenders fit about as well as any custom carbon fiber part is going to fit, so I might have to rethink that. I had to spray paint the screw to get it to look decent. That won't hold up, but at least it'll look okay while I find something powder coated. If I can get it to look good, it'd be something like this:  The bike doesn't ride any differently, and those mirrors are way more functional than I'd expected. I still need to do the rear blinkers, but that'll be easier because I don't have to remove the tank or anything crazy like I did for the front. I also might do something with the exhaust but we'll see. If I had any kind of 3D scanning/printing skills I guess I'd try putting together some kind of screw/clip that would make the recess in the fender flush but I'm simply too lazy for that.

triumph 675 update This is one of those feel good situations when you realize the previous owner hammered the seal in like an ape and tore it up and you dont have a failing output shaft bearing. I can just install a new oil seal and be done. The way I get these out is to drill a tiny pilot hole with the the drill and then stick whatever screws are handy into the seal and pull it out.

Re: tire warmers. I love em’ Our tire guy sells pirelli and it seems to be the ticket for the pace + climate in New England. We’re battling a big swing in climate. You have 40f and cloudy some days and 90f and sunny other days and those are very different situations that would require different tires if money wasn’t an problem https://www.pirelli.com/tyres/en-ww/motorcycle/all-tyres/sheet/diablo-superbike One added benefit of the warmers is it keeps the tires from heat cycling too much which deff something they weren’t designed for. Warming them up on the track tends to eat them up before they’re hot and sticky. Then there seems to be a big range of tires and what they’re designed for. “sport” tire for the street will not hold up to fast track riding. gets too hot and melts away at the faster paces. “track day” focused tires seem to be an ok compromise for fast riding. Really great for colder days or very light rain. These tires seem to be more flexible at less than ideal temps. then finally the best no compromise is the slick compound in either the dot approved format or the pure slick format. These are kinda crazy. They come with sticker on them that say not to roll them on the bike if its less than 45f out. they’ll crack the compound and then they’re ruined. Even at 70-80f on a nice day they seem pretty hard. putting warmers gets them up to where they were designed to operate. I most often run these or rain compound. The battle is I need the softer compounds at the beginning and end of season months when its cooler. Then the harder compound in the mid summer when the air temp + track temp is high. The softer compound cant handle the heat and melts away in a couple of hours. Also note. this is a 600cc super sport in the advanced group. smaller bikes or colder climates can probably get away with less than a racing slick. It’s frustrating to get it just right and not. destroy expensive tires

Strife posted:I actually put white grips on it. I really like the pro taper pillow top grips and the emig v2 lock on grips, fwiw. One of the nice/fun things about dirt bikes is plastics are pretty cheap so you can get all new colors. Custom graphics are ~$200 but if you have an idea, cormoto will do it for you and has done a good job for me. https://cormotographics.com/ you can spray sc10 on the bike too and that will help with rinsing off mud. Anyway, now you obviously have to buy all white plastics to match the grips.

White grips and plastics look great up until the point you take it out of your garage. I really like the feel of pillow tops but they're not very durable. I put a brand new set on last year and dropped it on the first ride, tearing the new grip. I'll probably go for something else next time around.

Didn't want to bother to do anything serious today after work, and the rain finally passed. So I prettied up the spokes on the front wheel. And ofc I'm missing a good picture of how it was before I touched it. here is a grainy zoomed in one.  As you can see there is a good bit of proper brown rust. Today's tools of choice. a dremel with one of the wirewheels that lasted for 3 mins, and some steel wool.  What I started with today  And how it ended up, gave it a light coat of rust converter with a rag.  Could have done more, but the play set size wire wheels for the dremel was pretty crap. Sometime this summer I'll bother to put the bike on the engine lift. remove the wheel and the brake disc from the wheel. put the wheel on a proper work surface and I can go to town with a normal wirewheel. But, not today. Spoke kits and a million other stuff for the bike is available from https://www.kedo.de. Seems like there is a big enough retro rally/offroad scene down in Europe for a yamaha 80s offroad bike part specialist to survive.

Finally got around to trying to take the wheels off last night and ran into a stumbling block. The front axle inserts from the right, into a "nut" (really more of a threaded sleeve) held by the pinch bolts on the left fork. The way Kawi wants me to do the front, I loosen the right pinch bolts only, and turn the axle out of the nut. But in their infinite wisdom, the axle takes a big fuckoff 22mm hex bit (or allen key and a big length of pipe for a snipe). I did some searching and those appear to be real thin on the ground here. The other option is to loosen the nut on the left side of the fork, cause that takes a 17mm hex which I actually have, then push the axle out the right side. I'm probably bein overly cautious even asking this, but is that a reasonable idea? couple of shots of the axle from some dude on the big ZRX-specific forum

The 22mm allen key is usually called a spindle key in the UK and maybe other places and common as muck anywhere that sells motorcycle stuff. I'm not sure where you are but hopefully searching for spindle key might help. edit. Sorry if that is teaching you to suck eggs, but you never know!

Do you have the tool kit that came with the bike? That hex tool should be in there. A 13/16" would also probably work if that is available locally.

You can also use a 22mm car wheel nut + spanner. You can take it apart using the pinch bolts but when installing, you have to tighten the axle and only afterwards do up the pinch bolts. So either way you need a 22mm hexagonal thingy of some sort.

Ok, there's a shop right by where I work that may or may not carry those (their website lists 'em but doesn't show inventory). I want to get my new tires installed for the weekend, so if they don't have it E: they did have one, worked perfectly, axle popped right out, thanks y'all! I spent way more time trying to loosen the torque link nut at the back, which turned out to also be a prevailing torque nut once I vice-gripped the bejesus out of it. In retrospect I probably didn't need to do that at all. Note to self, check the bolt shop for replacements. I miss the Good Bolt Shop, they had all sorts of weird poo poo but they closed like, a decade ago, gently caress Phy fucked around with this message at 05:24 on May 28, 2021 |

Installed a new axle to replace the bent one I found earlier. It wasn't much of a bend but it caused the bearing retaining nut to be tight on removal and the bend was in the thread. $20 to get one made by and old British gunsmith. Oddly enough the unthreaded part is exactly 12mm so it appears to be half metric and half imperial (threads are 7/16 BSF.)

Oddly enough the unthreaded part is exactly 12mm so it appears to be half metric and half imperial (threads are 7/16 BSF.) I recently worked on a 1926 British Ner-a-car and discovered someone at some point had installed a dual row tilting ball bearing in the rear wheel hub, I couldn't figure out why until I was reassembling and discovered the axle was bent. Assuming they installed that weird bearing to make the wheel work on a bent axle instead of just fixing the axle. Why the gently caress wouldn't you just replace or fix the axle? I straightened it with an average hydraulic shop press and an hour or two. I'm not a goddamn machinist. How can you be so knowledgeable as to source a rare nonstandard bearing to substitute and yet not know how to just bend the loving thing straight? Whoever did this also coated the inside of the gas tank with a resin which dissolves in gasoline.

Especially the compulsion to do a weird workaround instead of fixing it the 'boring' way, innovation or no practical experience idk. They often have access to bizarre specialty poo poo like that bearing, whilst not knowing about the existence of the machine shop down the road. They often assume they are the first person to ever encounter a problem and must thus develop a solution from first principles, it's probably confirmation bias because I only see the bad outcomes but it seems like most of them don't even google the dumb poo poo they cook up to see if someone has already struck it before.
