Maybe an odd question, but is there a kind of front wheel chock you can push a bike into that'll stop it falling over by itself?

I'm moving shortly to a house that's bigger on the inside but has significantly less outdoor space for bikes, and it'd be handy if there was a way to park them upright that doesn't require faffing about with a centre stand.

Yes, those exist, you see them bolted to the floors of vans/pickups as well (although in those cases you'd add tie downs).

D shaped pilot screws are dumb as hell. My sons CRF70 has one and I had to buy the special motion pro bit for it and now any time I need it I have to search for 20 minutes in my toolbox instead of grabbing one of 50 different flathead screwdrivers

I knew about that type but didn't think they'd be able to hold the bike up without tie-downs applied, don't know why I didn't think to look for a video. Thanks!

I actually pulled the Carb today to just give it a general clean. Pilot jet is 25 and main jet is 155 per the JD kit instructions so I think that’s good. Still have to verify needle but I suspect it’s fine too.

@slavvy the mix screw took five turns before it bottomed out. Does that seem excessive?

At this point I’ll reassemble it as-is unless someone says “no five turns is insane”

Front wheel chock makes it a set-it-and-forget it type deal. No worrying about that front wheel going off-center and taking the whole bike over with it. It also simplifies trailering when you don't have an assist.

If you're looking directly at the screw, carefully and slowly turn it clockwise until the screw stops turning. This setting is 0 turns out. If you don't do this carefully, you can cause damage to the pilot screw itself or to the carb body. The screw is made of brass and has a very small tip and the carb body is aluminum. "2 turns out" from here is just two full counterclockwise revolutions of the screw. I do it in half turns to get it there and count out loud because I am very dumb. If you take the whole screw out for whatever reason (sometimes that passage needs cleaning) be careful because the screw has a very small spring, o-ring, and washers.

If it was 5 turns out yep that's probably excessive.

Yeah, you have to be careful with those screws. The tip can shear off in the pilot hole, plugging it. (This happened to me, and I have no idea how)

GUYS I am so loving HYPE right now

I reassembled the carb, moved the mix screw to 2-1/2 out per the docs and it is so SMOOTH now!

I don’t know which is hyping me more, the fact that I tackled a quick carb clean for the first time, or the fact that it seems to be much less rough. Throttle response feels better too.

I was ultra careful with the screw based on recommendations and it feels like I would probably have lost something if I wasn’t watching for it. Good calls. I kind of want to grab an external adjuster but I’ll wait for now. It probably needs some tuning but I’m happy to leave it as is for now.

I feel like carbs aren't as hard as everybody makes them out to be, but people get that stuck in their head, try to mess with them, go "wow so hard!" as soon as the first thing they try doesn't work and give up. Then they leave it slightly hosed up, and that's how we end up with so many used bikes with weirdly messed up carbs

Single carbs are easy, double aren't bad, banks of three or four suck poo poo though.

Yeah after tackling it I don’t think it was difficult at all. There are a bunch of parts that are easy to break like the diaphragm or are easy to lose so I think generally I expected it to be a lot fiddlier than it was.

Honestly I can say the same about just about every part on my bike I’ve torn into. Everything seems difficult or impossible until it isn’t.

Took the bike on the road for a few minutes. What a world of difference.Not even my lovely throttle control could get that bike to stutter.

I did have the engine cut out on me halfway down the block though because I forgot to turn on the petcock on the way out :lol:

The only way 3 and 4 carbs are more complicated is in the tuning cause it can be hard to detect any changes you make to individual cylinders. Everything else is exactly the same just x4.

V4 carbs are a different story as they can have some potential pitfalls you don't have on inline layouts.

I dread the day I ever have to monkey with the Rex's carbs outside of synchronizing them, which turned out to be remarkably easy with the right tool

It's not the messing with the settings I fear, it's the potentially repeated uninstall/reinstall. It's real tight in there and I hope you people with easily removable carbs understand how good you've got it. When I cleaned them a few years ago I did one carb at a time and made sure to write down every pilot screw setting and put it right back where it was. Fortunately it ran great right out of the gate.

Even with the synch I could see how easily you could end up chasing your own tail if you didn't stick to a plan.

Kawasaki and their idiotic little spring scrunchies and their hosed up immobile air boxes, gently caress em.

Then there's the guzzi twins with their incredible system of having two separate carbs on either side like a BMW, but then joining them together solidly so you have to remove both at once by sliding them out like an inline engine, thus throwing away one of the very few advantages to their stupid layout.

What is a good helmet comm system? Primary use would be for audio navigation from my phone. Might use it with 2-3 other riders if they aren’t too spendy.

Fairly recent models of Cardo are showing up used for decent prices on advrider and eBay. My buddy and I split a Pactalk and it’s pretty good. Bluetooth on it is fantastic, but comms range isn’t great. They seem to be best for fairly low speed, close riding like on dirt or getting around town. Ours are prone to key up if the mouth vents are open, and I’m thinking about making some better muffs for the microphones.
I haven’t used mine for audio nav because I just don’t use that at all, but given how well it works with iTunes and Amazon music on my iPhone 6S, I would expect google maps or similar to work well.

I use my packtalk bold for nav a lot and it works great. But basically it’s just a bluetooth headset so anything you can run on your phone will sound exactly as you expect it.

Anecdotally, I found comms range for my packtalk bold really good — I will sometimes auto-join up with my friends when they’re riding unexpectedly/intermittently blocks away in a downtown area and it’ll prompt us to meet up so that’s always a pleasant surprise :) I for sure wouldn’t plan on it to be anything other than line of sight, if we’re trying to decide how far apart to ride though. That’s just a safe bet.

if you haven't done it already, upgrade the Packtalk to the latest firmware, download the cardo app to your phone, and use it to adjust the mic sensitivity to its lowest setting. I'd suggest immediately uninstalling the cardo app after you tweak any other settings you might want, since it's otherwise pretty useless

Oh poo poo, thanks, we’ll do that. I read on advrider from a few users to not use the app at all because it’s crap. I didn’t realize tinkering with mic settings was even an option.

The app's a POS, but it's still better than the local driver + web interface they used to have to make settings changes. It's not uncommon that the app can't find the communicator on the first try, even when it's paired with your phone and receiving audio. Flipping Bluetooth off and on again on the phone usually straightens things out

What happens when the “RT” in RTV gets low enough? Does it just take longer to set, or is there a certain temperature that is actually chemically required for it to ascend to its final plane?

Asking as someone who may or may not have a space heater for his winter workshop.

Afaik, RTV is Room Temperature because it cures with oxygen/moisture exposure.

But does the reaction occur when the temps are low? I can’t be sure. It should say on the packaging it’s suitable application temps. But it’ll likely just be a case of a slower reaction (but with all things, at some point of coldness the reaction will stop)

If you’re truly unsure, you could just leave a bead on a bit of cardboard out overnight and see if it sets.

Fwiw, Toyota's opinion was something like if it's 20 degrees or above, you can seal up a sump or water pump and it'll be cured by the end of the day. If it's colder than that we were instructed to leave it to cure overnight.

I've been thinking of what my options are for making the MT03 a little friendlier for my long legs (need to increase peg to seat distance).

The options would be this Norton seat:

https://www.norton-motorsports.com/product/norton-racing-supersport-seat-yamaha-r3/

Or as I understand, there's a way to drop the pegs a little? How does this work? Looks like there's a little bracket and basically moves them down?

Is one preferable to the other?

Slavvy
Dec 11, 2012

A taller seat is much preferable to lowered pegs because it changes the weight distribution of the bike less. Lowered pegs have had a weird handling effect on every bike I've ridden that had them, the type of bike didn't seem to matter much.

Also they tend to scrape.

You can speed up cure with heat, but you don't really want to blast it and make it cure too fast where it shrinks and pulls away or creates gaps. So if your garage is cold, a heat lamp to warm the surrounding area to 20-30 deg C depending on the stuff used is the safest bet.

Hmm yeah, ok that makes sense. This wasn’t prompted by any specific need, just in case I had to ever RTV something this winter. I’ll probably just wait for anything major until it’s warm because — let’s face it — if the RTV is too cold to set properly then I also probably don’t want to be in that frigid shed applying it.

Thanks for the info!
