G'Day All, my exhaust and carb. turned up today, I wasn't expecting the carb for about another week. I have fitted them up (wasn't the throttle cable a tricky one to remove. Shaka, I was just reading your post about removing the oil pump, did you end up getting the plug from Japan or did you go another route? I was wondering about removing the drive gear and leaving the pump in place, Is this possible? Not long now and will see how she goes. Zombie, thanks for sending the carb needle but unfortunately the carb turned up first. I will send it back when it arrives. Again thank you, that was very generous and I do appreciate it.

I haven't gotten around to getting the oil pump plug from Japan yet.  I'm currently using the expansion plug.  I just ended up modifying the bracket that holds the pump in.  I flattened out the tab that covers the top so that it rests on the expansion plug.  I haven't had any more troubles with it since I put the bracket on.  The gear is not removable on the pump, it is all one piece.  I've heard of people grinding the gear off, but I found it easier to just remove it.  I also didn't want to destroy a perfectly good pump, for some reason.

Yeah, I agree, I like to keep everything reversible so it can be put back to original if needed.

Just wish it would have done you some good. How did the carb mate up to your manifold?

[sidthesloth]

Hi zombie, the carb came as a kit with a power inlet, 4 reeds and manifold to suit. I have taken it for a ride, and wow, phenomenal improvement. with regards to the oil pump, the driveshaft just slides out so I put the pump body back in and blocked the inlet and outlet hoses. So the missus now gets the GPX.

Hey Sid, I just went and looked at my old oil pump and the shaft does slide right out!  Funny I never noticed that!  Nice one!!!!

[Shaka]

Sid- I don't know if you've seen it, but Josh @ Scooter Invasion is working on a 50mm big bore that's getting the WORKS!

No, I haven't seen it yet but I will when I can get these pics sorted.

[sidthesloth]

Yeah, I just had a look at it. Great stuff. Hey shaka, I see you're from Wilmington, I went for a ride this morning, through Pt. Augusta, Quorn, Wilmington and back through Pt. Augusta and home, about 270kms. all up. Just had to go for a ride, didn't get a chance on my last lot of days off. But this was Wilmington South Australia of course.

[Shaka]

Yeah, apparently there are Wilmington's everywhere!  270kms sounds like a nice ride.  I was happy with the 50kms I got in the other day!  270kms sure would wear on my back though!

I was riding the GS500, may be a bit much for a zx50. I tooksome pics of the spark plug that is in the scooter but I could only get one below the 192kb limit. I know it is not a correct plug chop, but do you think it looks ok. From the diagram that zombie posted a link to I thought it looked like somewhere around no.19.

[sidthesloth]

This is the exhaust. Looks pretty close to the original one.

[Shaka]

I think the plug looks pretty good, may be a tad on the lean side, but should be safe.  That exhaust looks pretty nice!  Is it an expansion inside that canister?

[sidthesloth]

Yeah, the initial pipe is larger and the sound is completely different so I guess it is. I will get some plugs tomorrow and see what that shows. I cant get 9s unless I order BR9-10.

G'Day again, adjusted the carb needle up one notch, seems to run better, more responsive from idle and more settled on cruise (just backing off throttle to maintain speed), heading in the right direction now.
