I sure wouldn't crack open a good engine thinking I'd improve on the job Suzuki did. Check the valves and install it.

Is it worth the work? The Sv will do a dozen track days and put through quite a bit in the twisties.

 

If it's been maintained it could go 100,000 or more. I believe if it ain't broke don't fix it.
Some may disagree.

 

I would also agree with everyone's comment...if it ain't broke, don't fix it. I'm relatively new to the SV community but it seems to me that it's a very popular bike and used parts, including complete engines are available at reasonable cost.

 

Have you priced a full gasket set? Fairly expensive and what do you gain if the motor is in good shape? As others have said if it isn't broke. The SV motor will stand considerable abuse and never have a problem. For the time and expense of rebuilding if it ever needed a used motor makes sense. If you're looking for more power through upgrades or lighter crank or rotational items than taking the motor apart is is logical..

 

I'm with the ,"If it ain't broke,don't fix it" brigade. If it runs well leave it alone. There's a guy on here who had an SV650 original engine with 178,000 miles on it !!!!

My 2 cents

 

one low cost benefit if you've already got the motor might be to keep an eye out for Gen 2 cams and do the cam swap. If you have a carb and exhaust gasket, you could grind the ports to match the gaskets, then when you install the motor, you grind the other side to match the gaskets.

 

The engine in my '03 SV1000S has 35K miles and runs strong. It does burn a quart or so in 2000 miles but that doesn't worry me.

 

Is a ,"Quart" 2 pints? I even tho' I'm an old school brit and brought up with imperial units we never use the the term ,"Quart".

My 99 on 36,000 uses between 100ml to 200 ml of oil and I change oil between 2,500/3,00 miles.

 

If you are going to bother taking apart a perfectly good engine, maybe get the gears micro-finished and install ceramic bearings. Otherwise IMO, it's little return for a lot of work.

 

Do anyone know how to tell what measurement of the thrust washer on the crank shaft? I saw in a manual that there are letters incase the crank case that may determine the size. Mine has the letter A. Does that mean the washer should be 1.995mm?

 

If that's what the manual indicates, it's the first thing I'd try. But if you're into the engine that far in the first place (which many haven't been), has anything happened which might require a different sized one?
