Maintenance Intervals

Maintenance is relative to your riding style. Some folks can get 5 rides on an oil change and others 1. Back in the 2 smoke days before hour meters I would change it every 3 rides. Now we have 4 strokes/better oils and for me the magic numbers are 4-5 hours. I have found my suspension starts to give up the ghost around 20 hours. The rest of the stuff is strictly as needed. FYI I am not that hard on equipment.

I have 2 bikes, one being a 21' yz125 and the other being a 250f. My 250f would obviously be different intervals but on my 125 my schedule is as follows

Oil change: 10 hours

Clean air filter: Every ride

Suspension oil change / service: 25-30ish hours usually works out to be once per season

Top end (specify 2t or 4t) : 25-30 hours

Coolant: every top end

Brake fluid: once a season

Brake pads: as needed

New chain: as needed

New sprockets: as needed

New grips: as needed

New / sharpen pegs: as needed

Front tire: as needed

Rear tire: as needed. Usually go through 2 rears to 1 front

New exhaust or re-pack: every top end

Grease pivot points: 20 hours

Lube cables: never. I should probably start doing this 

My KTM 125 gets something like this. 
-Top end at 20 hours. I can feel the compression start to drop around 15-16 hours

-Change oil every other ride, or before I go to a harescramble. I run the Honda 80wt oil and have nothing but good things to say about it. Cheap too. 
 

-I put a clutch in about every 40 hours, and they’re usually not even slipping by then. It always baffles me when guys on here say they smoke the clutch on their 450 in 20 hours 😅

-Air filter every ride, but don’t really have a choice in FL. 

-I pull suspension off to change oil and replace bushings and seals as needed every 25-30 hours. Cheap Maxima fluid works great for me and encourages me to change it more often. 
 

-Grease linkage/swingarm/steering head every 40 hours. 
 

-Every top end I do new coolant and clean the Powervalve. 
 

Just about everything else I inspect and replace as needed. I spend at least an hour washing my bike after every ride which allows me to really get a good look at drive and brake components. I bleed my brakes and clutch when the feel starts to go away, which is usually a pretty good while. I run Motul RBF660 in the rear because it can handle tons of heat and not boil, and then cheap Maxima in the brake and clutch. I don’t run the Motul all the way around because the higher boiling point fluids are known to attract more moisture and I hate the feeling of brake fluid on my hands so I want to keep it at a minimum. 

Just hit 30 hours on my kawi and I'm on chain slider number 5 and chain guide number 2. Just had to replace fork bushings, lower shock bearings, and a clutch. Everyone is different when it comes to wear items.

Tell me to pound salt if you want but I have went over 70 Hours on multiple KX's on the stock chain gear. The trick is to keep your chain adjusted within a narrow range and not let it get slack.. Maybe shorter service intervals to improve bushing life as it is a non issue for me as well.

I agree. I think my issue is the sand track I ride. The sand and clay get caught in the chain and the chain tension is good. Once I wash the bike and lube the chain the chain will be slack. I clean my chain with a brush and lube it between every moto, even bought a cordless air compressor to use at the track.

Pound salt.

Ahhh.

Maybe an x-ring for you. Pounding salt ain't so bad bro.
