Felt weird to buy a computer for a bike.
And here’s the funny thing, with the right diameter engine mounting holes that the swingarm bolt goes through, technically speaking, you could throw that yzm500 engine into a 99+ frame, and if Yamaha did what I think they have done, that means it could possibly be thrown right into this exact bike your building into a 360. IF they didn’t change anything between the 98-99 mounting points, which I doubt they did. cant say for sure, but I have a suspicion that Yamaha didn’t change anything between the 98 and 99 engine mounting points, if someone is able to take 2015 plastics and subframe, and bolt it to a 96 yz, I think it’s a pretty good chance of it. Can’t say anything about rotating mass but it seems plausible that it’s taken into account with the level brc is at

But I get the before/after principle on that. It requires more compression and more ignition advance to take advantage of the presumptive benefits.
For me to try it, it would require a head with removable chambers like a Luke's phathead. I won't completely butcher a Ohlins head, between Dyno runs. But I'll make two chambers. And swap em
But the prob is, that I absolutely positively refuse to deal with any of these machinists who have a soda straw view of their own machine shop. If they don't have it on the shelf, I don't want it. If I can make it, I won't buy it. If I have to ask any of them to make anything, I'm not asking anymore. You can get one of these assholes to drill and tap a m6x1.0 hole in something if it doesn't come like that already. That's fine, they've got a business model, I get it. But I'm done asking machinists to machine anything. They all over promise and under deliver.
I am probably going to have to mail my crankshaft somewhere in Asia to a rapid prototyping service because no one within my own country will modify it. And that's WITH a Fusion 360 file to go with it. Basically, the moral of the sorry is: for those CAPABLE, the job is too small. For those WILLING, the job is too difficult. Oh, and I know, I'm the asshole, the machinists all walk on water.
But there are mainly small machinist out there who make amazing work with the most simple machine's.
VHM is in my small village they make their own crankshafts but also modify existing one's. Check out there website vhm.nl
Then a few years on, I'm working within a warfighting laboratory and we have these newer ones, cf50 something?...and they just LOOK like toughbooks. Zero ruggedization. I was like "where's my old school brick that doubles as a weapon of opportunity its so heavy?"
Well I got a fresh one to have and to hold, and I'm going to keep updating and gutting it until I can't anymore.
As for Japanese engines, what were you building? Sr’s rb’s jz’s, The typical japan power houses, or did you get into the original beast, the 1uz, the most underrated engine in my mind, A friend of mine went down to the states and won pinks in a r32
Edit
To iterate on the grooves for 4 strokes though, I highly doubt they would work, the chambers are too irregular and there are too many intersecting surfaces I feel, and the turbulence created by the channels in the valves and valve faces, I feel is more than enough to cause a mix in the combustion chamber, but for 2 strokes, the dome creates a perfect bowl, and the groove do make a different swirl inside the head to mix fuel and air properly, and reduce lean pockets that cause irregular burn patterns
No, im dead ass serious, do any of you have a laser cut machine, let's do an aluminum plate i can tack in the toughbook embossed spot with the YZ logo.
If i was a shitbag rioter, I'd just carry this computer as a weapon. You can be charged if you have a bat. But with this, when the cops roll up, you just start answering emails. Its 5lbs, made out of aluminum, has sharp edges. And a grippy handle that prob has decent traction for bloody hands.
Laugh all you'd like at these rollers. They're just a 3d printed poly. Only has one bearing, then an alloy spindle that sideloads the bearing when you torque it. So I'll go to home depot, buy a foot of that tubing on the hardware aisle and trim them to the proper stand-off length from the frame and sub frame. Already have the ti hardware laying around somewhere. A looottt lighter than a traditional 2 bearing rubber roller.
Will.it last? I don't k ow but this isn't a Toyota camry, I don't ride it to work, and theyre about 5 bucks each.
Pit Row
Well I wanted to be able to say everything was coated. Final batch.
Entire clutch, actuation rod, everything minus the two friction surfaces for the pressure plate and hub. Now those plates will slide left right like butter.
97 and 98 primary drives. Kickstart ring. 97 and 98 water pump. 88 power valve. See those bearing cages i pulled the needles out of. Every. Is. Coated. Brake pad tensioner plate deals. Some more brake pins.
And if you look real close, there's a clamp top for a Brembo front MC. Figured I'd coat that too so I could tq it down to the bar nice and tight and still have that slick cap to make it spin when I cartwheel this thing. I don't like the plastic wedge in the WC clutch. Sortve feels like it moves to me.
Also, more info about spark plug gaps and mods. I am pretty much a dope concerning those...
Thanks in advance.

As far plugs I dont really claim to be a genius there at all, but like I said before, multiple electrode plugs don't work, and you want the end of the ground strap to only extend halfway across the diameter of the bottom electrode. The old yellow box ngk for some bikes weren't like that and you could nick the end of the electrode off a bit shorter.
Indexing them with the gap away from thenintake.charge so the ground strap blocks rhe spark from being extinguished by the intake charge is supposed to yeild gains but ive never done thst back to back so that's just "so I've heard".
Those toughbooks are cool. I remember reading about one that apparently stopped a bullet/ saved a soldiers life in Iraq. Riot shield?
HPI - "we can install basemaps from Jobes 360 for you to start with."
Do ylu think, for a single second after reading this thread that those basemaps were installed? Of course not! So, I got a 750 dollar blank box that won't run a bike.
I'll generate the maps from scratch...for a bike I've never heard run....so I can hear it run. 6 maps, actually. Of varying ignition advance/retard profiles. Not looking forward to that.
I had to change engine builders. Tom Morgan flat out told me, and I quote, "I dont really have the time to spend more then an hour or two at a time on this, I cant even spend half a day on it."
Imagine an engine builder whom you're paying full price telling you thst he doesnt have time to do your shit because hes doing other people's, whom he recieved their motors AFTER yours. then after explaining to him 10+ times what you need done, he sends you a text message saying "im not sure what I'm supposed to be doing at this point"... because none of them listen. Its dismissiveness. Let's just say it was my pleasure to give one engine builder the name and address of a rival engine builder and say "put tracking on it".
Thats exactly how it took Rich at Dynoport 3 months to make a pipe...and made the entirely wrong pipe for a different bike, put it in a box and mailed it to me. Proceeded to forward him 4 emails with the info in them. Literally put a male spigot on a pipe with a male exhaust flange....a bike that has had a nale exhaust flange, without fail, since its inception in 1976. But, I know, im the asshole. Somehow.
Its disheartening but the fact is, most of these industry people whom we hold in high regard for their accolades on the national circuit over the years...are actually dismissive, lazy dickheads who laugh at anyone who isnt sending them a cookie cutter 5 anglw valve job they can just chuck into a Serdi and head to Chili's for lunch.
Invest in yourself, and your tools, because I'm telling you, these guys are just taking your money and laughing at you. Apply some self guided learning and do this all yourself.... because the 16 yr old vapers that these builders are ACTUALLY having bolt your shit together are way more careless than you want to know about..unless you actually believe thst Eric Gorr himself installed your power valve.
