1987 ZX750 trying to get oil filter out.

I found a thread where someone was able to get it out but they didn't explain how. My filter won't clear the exhaust under the bike. Is there anyother way besides pulling off the exhaust?

I just ended up taking of the header and it dropped right out. Still an extra 2 hours to the oil change. Haha. Have a new respect for moto mechanics.

Don't you love how they made it so you can come within about a 1/4 of an inch of getting it out but can't be done without loosening off the exhaust system. I managed to get mine out by loosening off the header bolts and removing the rear mounting bolts but even then it took some choice words and wiggling to get the filter out.

Yeah it's ridiculous. Not to mention all the body parts you have to take off just to get to the header. After all that I decided to do a few other things since I have it all apart. Ordered oil pan gasket and a new generator (well used). Hopefully I can get it all back together. Went the extra mile and bagged all the screws and bolts.

If you have questions on reassembly...post them. I've taken my 88 all the way apart and put it back together again more times than I care to admit. I was telling my wife I have most of the bolts and screws memorized at this point.

Good luck. Keep the old machines running!!!

Will do thanks. My bike happened to be missing quite a few screws and bolts already. Can't wait to ride it. I think I need to replace my throttle cable have you done that yet?

Yep, been through the throttle...that won't be bad for you. Of course the tank will have to come off. The only hard part is getting the cable out of the linkage on the carb. I just twist the throttle open and hold the linkage. This allows for slack on the cable. Use a narrow set of needle nose to slide the cable off. Post with problems.

not sure about similarities but..

I was told by a mechanic that the center bolt of the oil filter cover (on my 600r) will pull out of the center allowing the cover to slide past the exhaust. I haven't tried it myself but you might want to check with another mechanic about this. My first attempt, I loosened the header bolts too, but was told it wasn't necessary. The setup on a 750 can't be much different than mine. Tim

Thanks for the help. I changed the oil pan gasket which went pretty smooth. Oil filter's back in. Now I'm trying to tackle the carbs but can't seem to get them out. Throttle cable is off and all the bolts are loose any tricks? I've read my haynes and I've done what it's asked.

You have to be a bit heavy handed to get the carbs off. Make sure you have loosened the clamps right off, then get a good hold of the carbs and push them forwards and backwards. Eventually you'll get some movement and all of a sudden they'll come off. The rubbers are very thick and have very little flix in them. I think from memory there is also a ridge on the carbs that seats into a corrisponding step in the rubbers.

When you put them back in try putting a little copper-ease on the insides of the rubbers. You dont have to work so hard to get them back in then.

I think the ZXR750 and ZX7R must be different cus my oil filteris easy to get at, don't think it has anything to do with the fact that my 7 has an Akropovic exhaust. What I would recommend to anyone play with their exhaust headers is to replace the manky steel studs and nuts with stainless bolts - no rust, no messing

I got a buddy coming over to give me a hand. It's just akward trying to get both hands in there so I figure if we each take a side should get them out. Thanks for the input.

Yeah I had to drop the exhaust but what oldschol said about dropping the bolt makes sense. It would probably clear that way.

Yeah, don't be afraid to put some muscle on them to get them off. The first time I pulled mine...they had not been off in a while, so the rubber had kind of sealed. Once it broke loose it became easy to slide off and on.

Just be careful...if you pry to hard down, you can crack the carb boots (if they are original like mine). Concentrate on pulling, not just prying them down. You'll get 'em. Two guys on it will make it alot easier too.

Resist the urge to pry between the boots and carbs with anything (like a screwdriver) unless you want to buy new ones.

Good luck!

He's working on a 87, it's really a GPx750. Totally different than the ZXR750 & ZX7R, the ZXR replaced it in 89.

Alright got the carbs out now if I want to clean them do I need to order any parts or can I just take them apart to clean them?

Also I'm trying to bolt the header back on and this is a far as I can get it to the block. Isn't it supposed to sit flush? Well, the flanges to the block?

Another question. 18mm spark plugs bought a spark plug socket and it doesn't fit in the cylinder head. Where do I find a slim wall for a spark plug?

The dealer or a motorcycle salvage yard or ebay.

Get a complete tool kit for your bike if you can.The only part you really need is the spark plugwrench but the rest is handy to have.Check your pm's too.You have mail.

Heat cycle the engine then recheck the nuts to make sure they're tight.

If you're stripping the carbs, I always replace float bowl rubbers and float level plungers. Make sure you strip out ALL rubber components before using alcohol based carb cleaner cuz it does funny thing to rubber. If the bike has been running fine I wouldn't take out the pilot or air bleed jets as they can be a problem to set-up again. You can take out the main jet and defuser tube to check that they aren't gummed.

Oh, and don't mix the bits up from carb to carb, do one at a time. Wow, the way we're going you'll have a totally new bike at the end, lol.
