Dump & Run Motorcycle Fork Oil Change: NonAdjustable Damping Rod Telescopic & Upside down Forks

Most nonadjustable forks are damping rod forks. 9 times out of 10, stock fork oil in nonadjustable forks is too thin off the showroom floor requiring thicker oil immediately. Regardless, fork oil wears out just like engine oil. Changing it every 5000 miles (8000 km) is excellent, every 8000 (13,000 km) is good, every 10,000 (16,000 km) is okay, and by 12,000 (20,000 km) it's become more like fork water than fork oil.

Your content is so good that I didn't even skip through the oil running out of the fork incase I missed something you said during it

I did a dump and run and followed the last video to a T and now my R6 rides over bumps so much nicer and nowhere near as harsh. Thanks Dave!

Even if the suspension components aren’t on my bikes, Im learning a ton about proper operation, setup, and maintenance of suspension. Thanks!

Fasten your seatbelts....Events occur in real time...while waiting for the oilflow to change from stream to drip....that made my day, very funny. Thank you DMT.

A very professional set of experiences and practice from the field.Thank you.
I am verifying my knowledge and ideas.
Grease - I use permanent grease (for brake callipers). It works.
Spacer - I modified according to logical thinking. According to your practice as it was found.
Oil - when the bike jumps up after compression, it gets a higher W ;-)

Waiting for my Maxima 20wt. for my Yamaha FZ6R to arrive Friday. Thank you Dave for these videos and your help. Without witch, I would have never attempted this service. Super squishy forks and after 31, 000 miles on my OE oil I'm way past due. I never thought about changing fork oil until I stumbled across one of your videos. Glad I did. Thanks again. I'll update in a few days.

Turned out great! Old oil was extremely silver, bike doesn't dive anymore and ironically it shifts better than it ever did. Didnt expect that to change from changing fork oil. Just what the fz6r needed.

There is tons of forums for information to reference on how much fluid required.

The simplicity of dumping oil and refilling is mostly overlooked, for the benefits over cost it's definatly worth doing at home.

The "fasten your seatbelts" comment got me :P

You make it look so easy. I replaced the fork seals on exactly the same forks and it was a pain in the ass the first time (mainly because I couldn't get the ABS sensor out).

Phenomenal sir! I thought "conjurer" when the high temp grease vanished, then the "stickage" went away, wonderful
