The photo is an XLR250 BAJA I used to ride back in the day. *Not related to this work. Just feeling nostalgic~
Wow, it really screams 20th century… Back then, if you wanted to take photos easily, you’d use a Fujifilm QuickSnap.
It’s supposedly 35mm full-frame?
*We do not accept any work on motorcycles and scooters without current inspection certificates. If you have a main bike with us, we can work on a second bike.
This is the only muddy bike at our shop. It’s being used the right way, I think to myself.
Dusty means we just wipe it down without touching anything. Pretty easy, right?
I was a bit startled… Here’s what proper emulsification looks like.
I seem to recall… the serviceability was really bad… How do you even get it out…
You have to remove the intake manifold too and give yourself a lot of clearance.
As expected from Keihin and Honda, this vacuum carburettor is packed with annoying mechanisms.
A TPS is installed but it’s not adjusted…
There’s a diaphragm and valve installed. The linkage that lifts the piston is interesting too.
It’s so esoteric~ I’d really like to see the manual.
Since it’s a running bike, the inside was clean.
I cleaned just the essentials.
This is how the piston lift linkage works… Pretty high-tech?
Quick, quick, quick~ all cleaned up.
I always think about it… it really is the equipment that makes the difference… there’s no going back to the old days…
Wistfully.
I also applied Gun Coat to the fine details. Just a little bit really boosts the finish.
Rubber float valves have a long service life.
However, bikes with rusty tanks or long-term storage need replacement.
The stepped tip is something I haven’t seen much of, but
• Rust creates a wet-blasted, rough, worn surface
• The rubber tip becomes hard like plastic
• The body wears and tilts
and so on… If you’re concerned, please have it replaced.
The fuel level has a strong “don’t touch the whole thing” vibe… As expected from a Keihin carburettor.
Then we assemble and we’re done.
Replace the intake manifold, clamps, and hoses.
Spark plug… I’m glad I ordered it ahead… I’m glad it came out…
We cleaned the air filter and lubricated the chain, and
We replaced the fluid.
The engagement that was so-so before now goes tat-tat-tat~ ♪.
What’s strange every time is that with a running carburettor with no clogs,
there’s no major problem—just cleaning, checking, and reassembling brings it back to life significantly.
It’s amazing how a tiny thing can hold you back, and I learn something every time.
All done.
