97 GTX is it done

[dfishin]

Motor went with out oil. I know 1 cylinder has no compression, but will I have to rebuild the whole motor? Your help is really appreciated.

 

[kustomkarl]

Chances are if it ran out of oil, it got hot and cooked the engine real good...The only way to tell is tear it down.
Good luck.

Yes! You will have to replace or rebuild the crankshaft. If you just do the top end, your crankshaft will fail soon. (How do you think I know that?)

Is it just cheaper to buy a rebuilt? Checking prices it's almost the same for just parts verses a rebuilt.

if , you can do work yourself..take a gander

I have rebuilt 4 strokes. This would be my first 2 stroke. Is the any special tools needed, other than a fly wheel puller? I guess I also need to find out what kind of shape the cylinders are in also.
I appreciate the info I'm getting.

2 strokes are much easier imo. SBT all the way never had a problem with them I get the 1 year warrentee but the premium engines have a 2 year warrentee,
(spelling is not my strong suit)

Make sure you get the rave valve in the right position....:agree:

ya i guess i will have to give them a call. i think the crank is out in mine. turns over, has compression, spark and fuel. just a little sluggish when cranking. like the battery is dying, even with a new battery.

 

[dfishin]

Going to pull the motor. Any make sure to do this or that?

 

[JESSECONSOPOLUS]

It's not too bad, I would take plenty of pictures of how and where everything goes. I'm very forgetful though!! Good luck, guess I will be joining ya. I think mine is wasted too!!:ack:

 

[dfishin]

Pulled the motor. Busted 3 head bolts taking head off. I'm planning on a rebuilt motor and going to call SBT tomorrow. Is there anyone else I should check out. I need to do this asap.

 

[timmyboy76]

busted 4-bolts in jugs, and cost me 50 buks to have machine shop, drill them out and then run tap in all da holes...?

 

[JESSECONSOPOLUS]

Dang that looks aweful!!! :ack:

SBT on the web! Thats what I did last year on my 97 GTX. Engine came with color instructions and if you have questions they have excellent service tech to talk too!

Good Luck!

I checked around here to have it rebuilt and every one was in the $2000 to $2300 range. So I ordered the SBT 1yr.
Now can someone give me some tips on getting the exhaust bolts out without stripping the allen heads?

 

[GTX rider]

You can try a tool called an impact driver. I used it on mine. Get and allen bolt socket for the driver, put it in the allen bolt and you hit the back of the driver with a hammer. It breaks the bolt loose. Link below shows what I used.

Thanks!! I will give it a try.

On the rubber cover that goes on PTO flywheel and shaft. Do I have to get the tool and those special clamps? Or is there something else I can use?

You can just re-use the clamps.

[dfishin]

Thanks sounds good, but what do I use to put it on?

 

[dfishin]

Pulled off the parts on the old motor and cleaned them up. Recieved the SBT motor a day early. Gona start putting the parts on the SBT motor tomorrow, which looks nice.

 

[dfishin]

IT IS DONE! Yep have to take it out and do the break in. While putting it back together I could not keep from thinking. Should I block off the pump and mix from now on. I don't want to go through this again and if I keep it mixed I don't need to worry about someone running it dry. What do you think?

 

[timmyboy76]

your call

its a toss-up stud. You'll use 10x as much oil going premix, then you would with oil injection, but then again, only takes a grain or 2 of sand/air bubble and BOOM....

 

[dfishin]

How do you test the oil pump to make sure it is working correctly?
