Title: motor blown
Post by glentally on 05/27/15 at 22:22:31

My son 's bike blew the engine, ( or so the shop says).  He was driving it and it made a terrible sound.

I've never taken a motor apart, let alone try to fix one.  Is it a futile effort to at least see if I can find out what is wrong?

If I was able to get a replacement motor are they difficult to swap?

where are you at?

Swap's not bad...
Rebuild,... takes some machining, and will cost...

Where are you located?...
Is English your first language?...
Your location tells us a lot about parts availability..  and how we can help...

Yes. More than likely you will just cause more damage. An "engine" (a motor is an electrical device) swap is more in line with the skill sets of the average person, but even then you'll need basic understanding of mechanics and a good tools set including torque wrenches.

The Savage is a good bike for "First Timers", and generally the mechanical training starts with maintenance items like oil and filter changes, brake adjustments, brake pad changes, valve adjustments, replacing the petcock....fixing headlight rattles, etc.

Rebuilding an engine is not really something that I would suggest for a mechanical beginner, and even doing an engine swap is an advanced exercise for a novice.  It involves taking off and replacing the seat/fuel tank/carb/exhaust/electrical/battery box/drive belt/footpegs......and then getting them back in the correct order.  To make it even more challenging most used engines come with some of the parts stripped off (starter, stator, drive pulley,etc.)  and you may have to do some engine work prior to bolting it back into the bike .

I am not suggesting that you give up on "helping" or getting help to make this a running bike again.  Once we know where you live we may be able to get you some help.

Do you have any indication what happened to make the noise?  The cam chain tensioner can overextend and result in a crunch on a bike with 10,000 - 20,000 miles showing on the odometer.  The other internal parts can crunch if the bike was run low on oil.

What year, miles, any maintenance you're aware of.
Drain oil, run a magnet through it, look for aluminum,too.
Depending on damage, a used engine is a good idea.
In fact, if you CAN salvage the engine,then slap a used one in,
Build up the currently shafted one, swap it in, sell the used one..
You get to ride AND learn all the ins and outs of the guts of it,
Hop it up, great workbench project for the off season.

Well, you guys have fun sweating engine,motor, throw out
The Rule.

I have my own pet peeves,   but, I can't get on board that particular one..not until they stop selling outboard motors.

Yeah, "outboard engine" just doesn't sound right  :-?

We aren't helping the guy any more.

How did the motor die, anyway?
Pretty rare event.

'blew the engine" isn't much of a diagnoses. Did the shop say what they thought might have happened ?

Making a "terrible sound" is probably not good news, but if it was my bike I think I'd invest the time to at least pull the side covers off and and take a look, and do a compression check, before I decided on a course of action.

If the engine is trashed there is an other choice besides rebuilding or replacing it. Depending on the age and overall condition of the bike, it might make more sense from a financial standpoint to just cut your losses and get another motorcycle. These bikes, especially older ones, aren't worth all that much. The cost of an engine swap or a rebuild might very well exceed the value of the bike. You might be able to recoup some of your loss by selling the usable parts of the bike, either on this forum, or on ebay or craigslist. You'll be surprised how expensive some of the parts for these things are if you buy them new. There is a substantial demand for used parts. I'm not necessarily advocating this as the route to take but it's something to consider.

It's a big enough hassle to join a forum for the reason of joining, swapping information,
But do all that just to see how many people will try to help?
I guess it takes all kinds.

So, you are saying this guy is a Troll ?
I'm curious how you decided that - some super secret moderator info that the rest of us aren't privy too, or what ?.

I'm not arguing,mind you. I'd just like to know for future reference.

If he were, it woulda been a more touche subject.
As it is, you guys have gone off and we're working on the second page.

Full Definition of MOTOR
1
:  one that imparts motion; specifically :  prime mover
2
:  any of various power units that develop energy or impart motion: as
a :  a small compact engine
b :  internal combustion engine; especially :  a gasoline engine
c :  a rotating machine that transforms electrical energy into mechanical energy
Origin of MOTOR
Latin, from mov[ch275]re to move

Full Definition of ENGINE
2
a :  something used to effect a purpose :  agent, instrument <mournful and terrible engine of horror and of crime — E. A. Poe>
b :  something that produces a particular and usually desirable result <engines of economic growth>
3
a :  a mechanical tool: as (1) :  an instrument or machine of war (2) obsolete :  a torture implement
b :  machinery
c :  any of various mechanical appliances —often used in combination <fire engine>
4
:  a machine for converting any of various forms of energy into mechanical force and motion; also :  a mechanism or object that serves as an energy source <black holes may be the engines for quasars>
Origin of ENGINE
Middle English engin, from Anglo-French, from Latin ingenium natural disposition, talent, from in- + gignere to beget — more at kin

The above is from m-w.com

motor is not limited to electrical devices.  although I remember hearing the scientific definition of motor vs. engine in my electric motor class, that's 30 years ago.

Thanks to all of you for jumping in.. My son Jay is going to tell you a little more like where we are and what the sounds where when it went down.

I was skeptical of the shop when then they told him they looked thru the spark plug hole and saw the  problem.  He will post soon, thanks again.

I have a friend that can do the engine swap if I ask him.
