It's time for me to replace my radiator hoses and repair the corroded metal tubes.

Does anybody have any experience with AS3 (https://www.as3performance.com/products/yamaha-mt-07-fz-07-2014-2019-high-performance-silicone-radiator-hoses-blue and https://www.as3performance.com/products/yamaha-mt-07-fz-07-2014-2019-stainless-steel-radiator-hose-clips-clip-kit) or even TBS (https://taiwanbigscootershop.com/products/professional-reinforced-7p-silicon-water-hose-for-mt07-2014-2019?variant=29500538388579&country=US&currency=USD&utm\_medium=product\_sync&utm\_source=google&utm\_content=sag\_organic&utm\_campaign=sag\_organic&srsltid=AfmBOoqIz---HVcAeKh0d9-\_f8AorP6Us5JSAvw8Tt5W\_uOzVSjyo2oOGm0)?

I like that TBS comes with everything including the top, thin hose, which AS3 doesn't include. They're somewhat comparable in price with the hose clamps added to AS3. However, TBS is not well known and I'm not sure if I should trust/risk it.

Side question, can anybody who has used either of these report as to whether the blue heavily sticks out against the yamaha purplish blue, or does it provide a nice accent? Might it be better to just replace all OEM or wait for the black silicone hoses to come back in stock at AS3? Thanks!

I'm replacing my chain and it's known that you should replace sprockets at the same time. But...does this look worn enough to warrant that? It's basically just through the surface paint, and not even fully. This still seems practically brand new. I replaced it at least probably 8-9 years ago, but I don't remember at what mileage and my bike only has under 24k on it. Do I really need to replace this? I know it needs cleaned.

I took my swingarm off recently to address rust and ended up finding that my chain has chewed through the guide/slider (which I didn't realize was there, let alone sacrificial) om the bottom and into my swingarm's factory weld. It's 1/4" wide (each of the grooves), about 1/2" long, and about 1.5-1.8mm deep. I took it to a shop on Wednesday to get these spots filled in with a welder, but ended up taking it back today when he still didn't have this project done (he told me Friday, then Saturday, then today and it still wasn't done). At this point I'm ready to just move on and get this thing painted so I can move on with the rest of the maintenance on my bike, too.

My question is, given that this is just on a weld and not the structural tube itself, would you just continue and be sure to keep an eye on the guide/slider (I am replacing it) from here on out, continue to find someone to fill in the weld, or fill it with bondo so there's at least some wear layer before it hits metal again? TIA

I'm taking apart my bike after years of neglect. It started as an oil change and has devolved little by little to getting into the valve cover. Yesterday, I noticed some oil in my airbox and thought it was excess air filter oil. Pretty sure now that it's not, since it's brown and smells like typical engine oil. I pulled the airbox check/drain cap earlier today and it was full of the oil, then I noticed that the oil seems to have come from the breather hose at the top of the airbox (pic1). I then noticed that there is oil on the engine directly under the check/drain cap (pic2), indicating that oil has either seeped from the cap or between the seams in the airbox. Then I saw that the oil seems to exit from the engine-side of the left throttle body and runs down the engine a bit (pics3+4). The oil doesn't appear to go above the throttle body, so I'm pretty sure it's from the throttle body, and it's barely under the head gasket, so I'm pretty sure my head gasket isn't leaking (on the outside, anyway).

​

Yesterday, I had pulled my right spark plug and noticed that the threads smelled like oil. The electrodes were dry. I'm fairly positive my valve cover gasket is leaking at the right spark plug tube, so I'm now stripping the bike down to replace that. I pulled the left spark plug cap today and the cap seems a lot cleaner than the right one was. I have not pulled the left spark plug to inspect yet because it's too late to start my air compressor to clean it out first.

​

I vaguely recall having filled the oil pretty full the last time I did an oil change (thinking a little more full is better than not full enough), so my thoughts are that I just filled the oil too high and that caused not only the gasket to blow from the oil pressure, but also oil to get sucked back into the airbox through the breather and then into the throttle body, which slowly leaked over time. The fix would be to replace my valve cover gasket and only fill oil to halfway at the sight glass from now on.

​

Does this seem like a fair diagnosis and plan of action? Does anybody have any other advice or suggestions about things to check?

I'm a pretty handy guy, but have yet to tackle any drywall. This is about 22"x26.5" Company wants me to sign a Letter of Intent before they give me an estimate on patching this, which would cost $150 if I end up canceling with them. I've found that I should be able to get the material for this project for around $150, including R-30 pink fiberglass batt, 2'x2' drywall patch, mesh tape for the seams and thicker fills, paper tape for the corner at the closet, mud, and tools. I have enough wood for any necessary blocking.

How much would I roughly anticipate this to cost for the company to do it and would it be worth just trying to tackle it on my own? Would it be worth signing with them and getting their estimate, then canceling if the estimate ends up being significantly over $300?
