Which will last longer? 4stroke vs 2stroke

[jwisniew]

Ok ive got a question, if a 4stroke engine and a 2stroke engine were put through the same abuse for year after year which engine would last the longest?

[Chanman420q]

simple a 4 stroke.

[jwisniew]

yea thas what i thought too, but a couple guys i know tried tellin me the 2stroke would last just as long

[Tom Lynn]

My nieghbor has a 2000 Blaster and he rebuilt it last winter and whenever he goes ridin he has me go with him and I actually ride like everyday but I go with him and hes gonna have to rebuilt it this winter too he is mad because mine is still good and the motor is a 1986 and still never been rebuilt up to a week ago IT DIDNT BLOW UP I just put a 10.25 wiseco piston in it for performance

on average a 4 stroke can take better abuse, but a 2 stroke can last just as long.

In a length of time, a 2 stroke will require more maintance (rebuilds) than a 4 stroke. Both strokes will last but its also how you take care of it also:D

[Maxxed out]

Ya you could baby a 2 stroke and ride it easy and it would last just as long(but know fun babying a 2 stroke). But after a while you would have to rebuild it before a you would have to rebuild your 4 stroke.

In reality, it depends on the whole situation.

The 4-stroke will last much longer before needing a rebuild.

With proper maintenance, a 2-stroke will last just as long as a 4-stroke.

A 4-stroke top end rebuild is typically more expensive than a 2-stroke, because you are dealing with valves, valve seals, cam(s), rockers, ect... along with the typical cylinder boring, piston, rings, clips, and so forth. They are much more complex. A two-stroke top end consists of boring the cylinder, replacing the piston and rings, and new gaskets. I've know people that have done a complete top-end rebuild on a two-stroke in a parking lot in under an hour.

no it wont, run a 250r motor hard for 4 years and see what it does



ive runn my 400ex from 99 til last year, and i didnt even need a rebuild last year, i could still be going on the same motor

[jwisniew]

yea a 2stroke is much easier to rebuild than a 4stroke but with how many times you'd hafta rebuild the 2stroke before the 4 ever needs one all adds up.

[MojaveKing]

man thos guys...were gettinmad..werent they jwisniew......i say 4 stroke

[heavy_d]

my zilla was just rebuilt this year and before that the engine wasn't touched since new and a 4 stroke costs more to rebuild, the bottom line is though do you want an insane power burst and its like comparing apples to oranges, if we didn't have the "don't have anything better to do enviromentalists" there would be more 2 strokes, its not because one is better than the other

When I say "Proper maintenance" that means a top end rebuild at appropriate intervals. A 250r tranny will last just as long as a 400EX tranny.

[pnut420]

I think either one will last awhile. As far as the blaster blowing up on you, it could have been because the oil injection clogged etc... My buddy had a 2001 EX will a few hours on it, and when he did a rebuild his valves were bent, so it all depends...

[400ex1999]

hey, u got a 350x conversion, do they race 400exs?

i never asked which was better just which would last the longest under the same conditions

[Tom Lynn]

U mean me

[flyin#5]

4 strokes can go a long time without a rebuild. but you have to remember you are running them at very high rpm's. much higher than 4 strokes.

[R-Crazy]

a 2 stroke requires more maintenance from a day to day basis. more rebuild, mixing gas, plugs, and so on. the rebuild are much cheaper and the bikes are wicked fast. i would gladly work on my 2 stroke and ride it than not work as much and ride a 4 stroke.

yep, thats what its all about.

We get more out of our bikes for what we put in than any 4 strokes can.

I have a four stroke myself and after putting alot into my engine and seeing everone else does, I would have to agree. I like the idea of their being no rocker arms to go bad or cams. I'd say stock vs. stock though a 400ex would be more reliable in the long run. I ran mine hard for a year straight with no oil changes, 4 trips to the dunes, got sand in the engine, etc.... And when I took it apart it didnt have much wear at all.

if your racing a 2 stroke, i would rebuild about once a year. i have owned my 250r for 3 years now and have only fouled 1 plug (proper jetting). the first 2 years i owned it i was on the same bore but i was only play riding and doing about 4 races a year. during the winter i had it bored over and i've done alot more racing this year and have found that nothing beats a fresh 250r for dependability. there easy to work on (ALOT easier than a 400ex) and imo alot cheaper. with propery maintaince a 250r is very dependale. when that new 450f comes out i might buy one to use as a pit bike to pick up the trophy i won on the 250r.:blah:

[MojaveKing]

bump.....any1..else have something to say to the matter

[TRX300X]

A properly tuned 2 stroke will go through the same amount of plugs and also require less maintance then a properly tuned 4 stroke. I work with 2 and 4 stroke boat motors every day and I see engines from the 60's and 70's come in that are still on the original bore and run reliably. A 2 stroke will last a long time if it's not high strung like the 2 strokes commonly seen in the off-road segment.

With a 4 stroke you have to adjust valves, change oil, and there are more moving parts therefore when something does go wrong it costs more to repair. But the quietness and the cleanlyness of a 4 stroke generally makes it a better choice over the 2 stroker.

[wilkin250r]

This whole "2-stroke is better, 4-stroke is better" argument is almost like the "Honda vs Yamaha" Whichever fits your needs, that's the one that's better.

Tastes great...

Less filling...

I've had good luck with both. My 87 250x lasted forever, still got it and I'm rebuilding right now. My x-father in laws 87 250r was just rebuilt last year for the first time, it made a hell of a difference. It still had alot of guts for going so long without being rebuilt, but he's very picky on how he mantains it. My 88r has been redone once 20 over, I take care of it and it takes care of me. I love em both especially as long as I can ride!!:D

[heavy_d]

2 stroke is mostly a racer have to be on the throttle a lot or she'll get wet, 4 stroke you can have a more relaxing ride and you don't get your arms ripped out of your sockets, i do like a 4 stroke every once in a while for putting around
