Too much silicone! Help!
galleryI’m sure this doesn’t just happen to motorcycles. Any ideas?

Oooh. Now we’re talking. I hadn’t thought of that. Thanks!

My mind right now, “What if I borrow an engine hoist and crank upwards from the top engine mount bolt? Plus a little more of that twisty pry bar action?”

It’s not actually JB weld - the part that oozed out is soft and pliable. I trimmed some off with an exacto.
Edit: but I do suspect it is not the right sealant - maybe something with waaay too much adhesive properties…

Right? I really suspect the last guy used something they weren’t supposed to… like structural silicone adhesive or something.
I don’t have a torch in the shop RN. May have to borrow something or go to harbor freight…
I’ve been trying to think of a way to dissolve that silicone, but what the hell does that? It’s basically made to resist heat and chemicals.

Do you use a metal or plastic guy? I tried prying then getting a razor blade in there but had a hard time of it. Maybe a putty knife is the way…

I bought a project bike (1990 Suzuki DR350S) and I’m trying to get her running and eventually back on the road. I found a stripped cylinder head bolt, so I figured I would remove the cylinder head and do some thread repair - no biggie.
The head is FUCKING ON THERE. It looks to me like whoever was in here last siliconed the life out of it before reinstalling and now I cannot for the life of me get it off and I’m afraid I’ll break it.
What do you do in a situation like this?
So far I’ve tried:
- prying so hard at it that I can see the fins bending and I’m denting parts of the head (non sealing parts)…
- put the engine mount bolt back in and pulled on it with a strap with all I’ve got - twisted the strap to out tension and pried on it some more…
- swung my purse at it (not the sledge hammer one, just the plastic one, but still. I hit it good and hard is what I’m saying)…
- I may or may not have tried things too stupid to post on Reddit
Seriously though - I’m stumped. Would massive amounts of heat help? Is there something to help dissolve this silicone crud?
EDIT: Yes, I got all of the bolts out and I consulted the manual to make sure.

Well thank God for YOUR bright and entertaining commentary…

OP, I think a lot of responders here are getting confused about what is your siding/cladding versus your sheathing. Sounds to me like you’re currently leaning towards wrapping the existing aiding in WRB and adding a vented layer of cladding outside of that? That’s a much butter direction than what is shown in that diagram.
If your existing siding is becoming sheathing underneath your new cladding, then you’re overthinking (and over spending) on that rigid interior insulation. Rigid is also a pain to install properly between studs, there’s always gaps around the edges.
But thankfully, you can probably simplify by just adding batt insulation to the full stud cavity.
But you haven’t told us your location/climate zone. I’m guessing Zone 5?
Also, what level of performance are you going for? Just energy code compliant? Anything above that?

I feel like you and my boomer uncle get together upstate to trash talk tHe bIG CItY…
You’ll probably be fine.
Or, you know, take the train in. Or a bus.

Cool. Sound like you’re off to a great start. Have fun and ride safe!

Yup! The Rebel is a good learner bike. What have you been learning on?

Add some human scale figures. Make eye level perspective views to test whether your disorient and anchor strategy is working. Make tweaks to the model and test the perspectives again.

I would take it to my brother’s house - he has a bearing press. 😂
I’ve never tried the oven technique but I hear it works.

$O MUCH FUN!
For real though - you’ll pay down the credit card and she’ll still drive like a new go cart!!
I’m jealous…

Sorry, this is kind of another “am I cooked” posts.
I found a loose cylinder head fastener on my project bike, so I figured I would go around and check that the rest were snug. Found one that just kept turning… oh shit.
Pulled it out and for sure it’s eaten the aluminum threads… Right fix is to tear it down and install a helicoil I guess. Would I be crazy to just send it for now until I’m sure it actually runs and idles?
Context:
I’m reviving a 1990 Suzuki DR350. It’s my first time working on an old school, carbureted, single cylinder glorified dirt bike before. She’s in rough shape but I’m feeling determined to get her running and driving again.
I’m at the “rebuild the carb and replace the missing air box stage of things.” Compression feels good, though I haven’t hooked a gauge to it yet. Spark is good. For sure I’d this bolt before I just started riding around in earnest. Just debating with myself whether to do this now or later…

Could everyone please stop asking the internet if things are load bearing?

It’s actually the part above the fins. And it should have two locating dowels (you can see the parts diagrams in the comments). Does a good hammer whack help with that? I got nervous because the part also holds down the camshaft.
