I just bought a 97 SX 600 with 6000 miles on it and I have a couple questions. First of all, it seems a little sluggish in low end power. At about 6500-6700 rpms, it starts kicking butt and screams with power. It has twin PSI pipes. Any thoughts or suggestions?

Second, it is guzzling oil. I used about three quarts on a 70 mile ride! There seemed to be some oil lose / spewing coming from the exhaust manifold by the pipes. Again, any suggestions. It does smoke a lot so I think the jetting might be a little rich. Could this cause the extreme oil use?

Thanks again for the posts, I am new to this board and looking for some sound advice.

So I read the article about adjusting the oil pump cable. I also called my dealer. He said adjust it with the throttle full closed (idle) . The post recommended doing it at full open throttle. Which one should I do? Also, I adjusted the adjustment nut and lock nut, but ran out of threads before I could get close to the alignment marks. Then I tried to adjust the actual end of the cable by losening the nut on botton, puled up on the cable to get the alignment marks close, but I cannot tighten from the cable side and always end up right were I began. Any thoughts????
 
set it with the throttle cable wide open, line up the marks and your done, adjust with the center of the cable not the end, if it needs more adjustment, the cable is probably stretched too far from use and age and you might have to get a new one, I have only had to replace one once
 
Ok got it adjusted just fine after doing it with WOT. Now a test ride is in order. Thanks again for the advice, this board kicks a$$!
 
So I adjusted the alignment marks at full throttle and it is still burning too much oil. Plugs are soaked but not fouled. Which way do I need to adjust the alignment mark? Do I adjust it so the mark on the lever so it stops before or after the alignment mark onthe sle
 
Any chance it is using way too much oil because the oil pump is no good? I had one die on my '97 venture at one time, and thats what it did, just used an EXTREME amount of oil, which I guess is better than dieing and not pumping oil. Replaced the pump, problem solved.
 
Well when mine went, I set the specs for the oil cable from the manual, and after it was STILL chugging oil even after the oil cable was set to spec, and everybody else was fine, I just assumed that was the only other option. Those oil pumps in those years were famous for crapping out that way, so I believe thats a good chance that may be your problem.

Just set your specs, if you are still having issues, I would look into getting a good used oil pump... since new ones are pricey.
 
Check continuity? Or figgure out what your fuel oil ratio was last trip then tighten the in line adjuster gap 1/4" closer (if the plugs were soaked last time like you said) than check your fuel oil ratio again on your next trip... if it doesn't change, there's your answer.
 
I used 1 quart of oil per 2.7 Gal of gas. I turned the oil cable adjustment 1/8" to begin with and will adjust as needed next ride. I did find a used working oil pump for $50 so I bought that too just in case.
 
Woah, my guess it that your pump has definitely calved. You're running around 10:1 at that rate. If it was working I don't think you could even adjust it that far out and still be able to pull the throttle cable wide open because the pump would bottom out before you were even at half throttle. Hope your new pump arrives quickly for you so you can get back out!
 
I can't picture it being very fun. They are pretty well underneath the engine. I'm sure you're going to take out the air box, carbs, motor mount and at least have to move the engine if that gives you enough access.
 
Anyone else have any experience changing this oil pump? It doesnt seem all that hard, I just dont want to pull it out only to find I dont know a special "secret".
 
Wayne084 are you sure you arent thinking about the FUEL pump? If I remember correctly, changing the oil pump didnt take too long of a time to do and I do not remember having to take all of that stuff out.

I am sure some guys on here can give some good ideas on how to do it correctly and easily.
 
Yeah the oil pump is on the side of the engine near the exhaust cans. Don't see it being that hard. I will try it tomorrow and post lessons learned.
