[15 ST 250]

If nothing else work....Try closing reed valve gap a bit...

[Trs chain adjusters]

Especially bad in dissimilar materials like steel bolt on aluminium. Worse when alkaline soap is used to clean the bike (always look the PH before).

Loctite, 3M and others have dedicated products to prevent bolt seizure. Worth a try.

[What about putting a inner tube on a 4.00 R18 rear tire 2005 Gas Gas TXT 125 Pro]

Had used tube in my old 2010 sherco without any problem

[280 or 300?]

Same carb or keihin vs dellorto too? Because there much difference here too.

[Cracked clutch cover on 2014 Racing]

S3 have a clutch cover for GasGas....maybe it is stronger....

[What does the wire fastened on the rear brake caliper on a 2005 GasGas TXT 125 Pro do?]

speedodometer I bet

 

[Front brake wont lock on 2018 Sherco factory 300]

Sometimes brake need some time to work propely after you change pads or discs. Just ride and have fun. After half hour it should be nice.

Bikepert, the white plastic part you saw in dogbones is a "thing" I made few years back when this bike was almost brand new. 

Your rear fender zip tie mod is a good practice. Will tell about it with a friend that keep breaking these fenders.

[Does more sticker give more HP?]

Yes, more HP and torque but....
unfortunately, all the effect disappear when you start riding and others see your real ability.

 

[New gas gas vs new Sherco, what should I buy?]

Looks like the video forgot step 1. 

 

WASH THE FREAKIN BIKE FIRST!!!! 

And on that wash your bike regularly 

Yes, this is a good practice.
Anyway, you should always wash everything after removing swing arm from bike.
And, yes, when I wash my bike I never spray high pressure water in links area. This part is always dirt.

I try in these videos keep things "real world" and simple as possible. The idea is give confidence to the one who want do the job first time.

Beware that at least on the steel forks removing the upper bushing as shown will destroy the teflon lining. The lower bush slips up inside the edge of the upper and scrapes the teflon off. The lower bush does not appear to get damaged.

Good ad. Bikerpet. On aluminium shocks too  Splatshop sell these bushings separatelly

I've done two videos on trials maintenance

Front fork and rear shock.

Same Honda shadow fork seals....

 

[2018 Sherco 250 Factory vs 2018 TRS RR 250]

Look for best aftersales support!!

[Marzocchi fork seal size]

Probably, 52mm is the lower leg hole diameter and 52,2mm is the seal outer diameter. this 0,2mm is for interference fit.

[Help needed on new style Braktec Monobloc maintenance.]

If torx T100 isn't available, be careful with improvisation a new tool since it can damage the finish. Protect it with a rag between tool and part. Probably a big nut will be able to turn this cap. Below the one I've made to formula brakes.

[Poly Fork Guards?]

...I'm using fork boots (gaiters). They keep all mud and dust out of seals and give some protection from rocks.
