It's real real good.

It's a 2013 Factory APRC Z3n picked up for lolol cheap and buddy dealed off to me to use as a track bike.

Have a buddy with a 17' Tuono and it may be the finest motorcycle on sale today IMO. 9/10ths the speed of the RSV4 but effortless and comfortable on street and track.

The RSV4 is an absurd bike for the street but phenomenal on a race track.

Now that the last parts have arrived I'll box up all the pretty street plastics and begin the conversion to track bike. New painted plastics, rear sets, said $60 Chinese knock off SC exhaust and Race ECU.

I noticed earlier this week that my outside clutch plate had dings around the OD, so I pulled the engine cover off today to see if, in the laundry list of mods by the PO, they had done the starter chain tensioner fix and the dings were just really old.

They hadn't and they're not.

Looks like I'm ordering parts tomorrow!

E: with any luck the new gasket I put on today will be easier to scrape off than the likely decades-old one that was on there.

Price was 28 Euro. Made in Germany by a company called Stahlbus.

They also make check valve brake bleed screws that you can bleed without a second person or air tools.




That's the next thing on my list.

The spice must flow in and through me.
The fire will cleanse me body and soul.


Yesterday I took the bowls back apart, got the needle vale, main jet, pilot jet, drain plugs, etc. off the '78 GS750.
Here they all are enjoying a good soak in some carb cleaner (it turns out I did have a bit of a can left).


While taking them out I noticed that the O-rings were rather gummer. You can see how they are less "O" and more "smooshed" on the main jet.
So I didn't risk loosing anything, I did put the carb back together, but I have a carb O-ring kit ordered to replace all of those. Every O-ring I encountered in there had that same gummy texture and I figured better to take care of them all now while I have it out.

I was able to get the pilot jets clear, so I think the engine might be able to actually run. We'll find out after the new rings come.

What was left after their soak and clean:

I bit the bullet and just got a carburetor rebuild kit for the '78 GS750.
I don't think anything other than the O-rings really needed replacing, but the gaskets were a little rough and the rebuild kit cost about the same as gaskets alone, so I figured it couldn't hurt.

I did find that someone must have tightened at least one of the mixtures screws with as much force as they could muster. The needle had a spiral gouge in it.
So mixtures screws replaced, pilot and main jets replaced, O-rings replaced on the bowl drain plugs.

I cleaned out the air cleaner thoroughly and found that there was no gasket between the air filter and where it was supposed to seal, so there was a good 1/4 inch of open space between the two.

I couldn't find anyone selling JUST that gasket, so I made my own out of some one sided reinforced adhesive foam.
Before getting it fully put in place:


Much better:


Found the gear position sensor wasn't hooked up, I guess the PO didn't care for it.
Works just fine:


I took it for a quick test ride around the block.
I'll need get the carbs adjusted and I didn't push it beyond 35, but the engine feels strong.

Really all that's left is get the chain guard back on, the trim pieces, and an oil change and I think it will be ready to roll (other than properly cleaning it up).

Not bad for a $900 motorcycle plus maybe $200-300 in additional parts, considering the PO originally wanted $1,200 for it.

I changed the front and rear sprockets ....and I only decided to change the front sprocket after I removed the chain :downs:

The engine sprocket nut was torqued to like a trillion foot-tons too. Hopefully I never have to struggle with that again.

I didn’t install the new chain since I need to take both wheels off to get the tires replaced and balanced, but after that I should be mostly done with the “overhaul” minus valve adjustment.

The '78 GS750 now has all of its trim back on. I rode it to the local motorcycle shop so they can tune the carburetors and double check everything else.
I did check the chain slack and alignment, but it felt like there was a tiny bit of wobble so I figured I'll have the pros take a look at that as well.

As far as the '94 Ninja 250, after I filled the gas tank last time I added some Star Tron fuel treatment. After putting some miles on it, I found it seems to be able to rev above 11,000 rpm just fine now, where it was just not willing to go above before. I guess it was that jet.

Welp, I hosed up installing my connecting link on new chain. I guess my crappy tool wasn't centered right and it split one of the rivets while I was mushrooming out.

I put in the crappy clip link but ordered a replacement. I'll get the guys to rivet it for me when I take the bike in for safety next week. Learning experience though.

Sagebrush
Feb 26, 2012

Clip links vs rivet links are a huge :can: here in particular but IMO if you're putting it on a low-powered bike (you are), you install the clip in the correct orientation, and you keep the chain oiled and properly tensioned, it will be fine.

I’m fully on board the “rivet supremacy” bandwagon but I just wanted the chain on the bike instead of on the ground. I don’t actually plan to ride the bike until they replace the link :)


Edit: what a big lie, I’ve been scooting up and down my driveway practicing my clutch. That’s “riding”, right? :smith:

Rivit supremacy for certain, except the common case of exactly what happened to you. That's why I always order an extra for when I break the first one.

Clip type is fine, though.

Rebuilt the lighting system into the rally fairing, as well as installing a dry box that houses an also-new phone charger for longer trips.
The charger runs off the (redundant) high beam switch and works great.

My (new to me) '97 Nighthawk has a master link chain. I'd be suspicious but the chain's at something like 80% of the way to the wear indicator so I think I'm good at this point.

Today I put on an OEM "main stand" (center stand). It sticks out a bit far on the left because there's supposed to be exhaust on both sides. I had to bodge my own bump stop to keep it from swinging up to the chain too (it's supposed to be stopped by the left-side exhaust). Just one more reason to keep an eye out for an OEM exhaust and trade out this Yoshi 4-to-1 for it.



I also put new plexiglass on the fairing. No idea why it took Rifle two months to ship it to me. Now I can stick on all the Iron Butt stickers I've been saving up. :dance:

I think you've posted a photo before but that's an incredibly handsome nighthawk.

I think all chains are master link, the difference is whether the master is clip or rivet.

That 4-into-1 seems good unless it's stupid loud - maybe replace the can rather than go stock? Must be a way to adapt the center stand without going dual exhaust

Yep, I meant clip. I'm used to bicycles where "master link" is the term they use for the clip assembly, maybe it's different in motorcycles.

It's not super loud, it just sounds "sporty" being a Yoshimura, and I prefer quiet exhausts (the electric bike to its left is just about at my ideal noise level). In my experience Honda OEM exhausts are on the muted side, and I like the megaphone look of the original. Just replacing the slip-on might be a good idea though.

The biggest problem right now is that the spring for the centerstand stretches against it and I'm worried it could cause a problem some day. I got the centerstand so that I could do chain maintenance / fix flats during long rides. Seems all right so far though, and maybe I can bend something out of the way.

because rivets are far more permanent and take like an extra 2 minutes to install compared to a clip

yeah but what if you're a dumbass that didn't do homework on transmission ratios, sprocket sizes, and chain lengths to figure out an optimal final drive ratio for both a dirt and sm setup so now you have to swap chains when you swap wheel sets and I'm wondering what's everyone's take on re-using clips over and over?

Elviscat
Jan 1, 2008

Well don't you know I'm caught in a trap?

I reuse clip links fairly frequently, the service manual tells you to go ahead and do it, I'd replace them fairly regularly though, the clip will eventually lose the appropriate spring tension though.

My rule of thumb is anything more than 40-50 odd hp gets a rivet type. Road 250's seem to lack the power to spit them off, though I've seen it happen, and dirt bike chains are usually so seized and lovely there's no way for the master to come undone; I've seen several where the spring clip had long disappeared yet the link plate stayed in place and needed force to remove it.

Big bikes? Not worth the risk imo, a snapped chain on a sportbike usually puts a hole in the engine.

I painted all my new fairings yesterday.

Then today I sanded down the loving $30/can clearcoat and re-applied because I’m an idiot who can’t read directions and has no common sense.

If I had thought ahead to the price of paint and what my own time is worth I would have bought these fairings from China already painted for $200 more.

Will finally get some pics up when everything cures and I’m not nervous about mounting it back on the bike.

Slavvy you talk about Honda being good but have you ever worked on a Honda RC51? I've never worked on a Honda where there wasn't some insanely dumb loving bullshit required. You've got these from day one doing poo poo like the CX500/650 stators.

The problem with Honda is that they have their engine folks do the engine work, and then the frame people do the frame work and then suddenly you have the Honda 929, where they put a frame crossbar over the spark plugs, or the VFR800 where the common technique to deal with the valve adjustment is "remove engine, throw in trash, purchase ebay engine, install", because the book time for the VTEC models is something staggeringly dumb. RIP to the goon who's missing out on a 701, those motors are fine and the bikes are rad.

If you want to ride a bike to save money, get a clapped-out KLR and ride it until the tires are bald and oil the chain with stolen mcdonalds fry grease or whatever those nutjobs recommend.

They do lots of dumb insane bullshit, especially during their psychedelic 90's peak, but it's nowhere near KTM/BMW levels and they hardly ever break by comparison.

I don't know where the viffer valve thing comes from, I've done it on vtec and not vtec models and the hardest part was taking off all the bodywork. I will say Honda fairings are the absolute worst and seemingly designed to be difficult to take apart.

Yeah, I priced a cable railing for my new deck, it was $2600, for a decent welder, steel, and various peripherals it was like $2200, I've been welding and grinding for over 40 hours now, but I get tools and new skills out of the mix, and if I ever want to do it again it'll take half the time, and new skills are invaluable, and, for me at least, it's time I'd probably spend loving off anyway.

My first tire change took me like 4 hours, including a pinched tube, now I can change a dirt bike tire in like 15 fuckin' minutes.



KTM chat: my Husky takes like 10 minutes and 3 bolts to strip literally all the fairings off, it has a million tiny little thoughtful features that make maintenance way easier than my old Kawi, or my FZ6 where I have to pull the front (only) fairing to lift the loving gas tank.

Admittedly I've only worked on the S1000XR, but the R motor platform isn't bad, and the Boxers seem okay for most stuff except gently caress doing a clutch ever. Or final drives. But shaft drives are banned from the eyes of god so whatever.

I'm pretty curious though about what you don't like about KTMs - in all the ones I've worked on, they've definitely got some weird poo poo (why so many filters? DURPKAR) and the early LC4 oil change procedure is absurd due to the dry sump setup, but everything 1190/later architecture seems fine and the 950/990 motors are stout as poo poo with a couple of known maintenance items. Besides that, their dirtbikes are amazing to work on because there's an expectation you have to fix it on the side of the desert unaided, and I've never been unhappy about working on any of the 690s.
