hey guys iv just been wondering how hard it is to maintane those thumpers, iv been considering maybe trying to get one
Not that bad. It's more than a 2 stroke but still not terriable.
oil change every 8 hours, new filter too.
I clean my air filter every other ride.
Check the vlaves 2 or 3 times a season (50$ for a mechanic to do it)
bleed the air out of the forks every ride (on 2 strokes to with bleeder valves)
keep chain tight, clean and oiled.
keep you tire PSI good
Basically just oil changes, valves checks and air filters. Then all the regular stuff to keep it running well. I'de like to see you on a 4 stroke.
Yeah I know what you mean. Anyhow 4t race bike have incredible low down torque, and all over really. You will feel very safe with the power because it havs exactly what you need, wherever, whenever and however. It's a myth they go through top ends like that. They last 2 times longer than a 2 stroke. 2 stroke + 2 times longer, 2+2= 4stroke.
If you need help with that stuff, get racing on your 85, then get some sponsers after you get your 250, then money won't be so tight compromising your bike.
yeah, what would you recamend most kx-f crf-r rmz or yz-f? iv heard yz-f has 5 valves which is realy nice
The important thing with 4t's is cleaning the air filter and I mean religiously. Other then that change your oil as often as possible, I change mine at least every 5 hours. That and check your valve clearances every 20-30 hrs, you shouldn't have to adjust them until 100 or more hours though. Not sure why Mihylo's buddy is adjusting his every 10 hrs, either he's getting dirt into the engine or he has other serious problems. After you adjust them the first time they seem to fade pretty fast to.
You also have to remember that just because one guy is going through 2 top ends a year doesn't mean you will. A ProAm or A rider who's always on the rev limiter will go through A LOT more parts then the more casual riders, plus their bikes are usually modded to kingdom come. Which takes away from reliability. For example, a local guy was telling me about how his kids 250f was so heavily modified that the engine would only last a little more then one race. But that monster could practically take a stock 450f. Also the amount of hours they actually ride will probably be different then you, due to them practicing every day. Practice 5 days per week plus races, compared to the casual riders who can only ride 1-2 days a week.
- Clean your air filter often
- Change your oil at regular intervals (Get a cheap hour meter to better track your time)
- Remember that you have massive torque on the bottom and there's no need to rev the piss out of them.
- Clean your air filter
- And just in case you haven't caught on yet, Clean your air filter.
