Cateye X1-X7 Exhaust help

If Im remembering right they are 6mm bolts and should be about 7/8"long

My cateye used m-9 metric bolts. Hope that helps

Thanks alot guys, that's why I love this forum, helpful people all the time. I was about to go buy 8mm bolts cuz i had read on another thread that's what the guy used on his however i'm gonna see if the guy at the hardware store lets me try the 6mm also before I buy them. I have to go get air in my cateye's tires anyway so I'm gonna take it with me. So why do the cateyes come with different exhaust bolt sizes?

The Cateye engine I have here has M5 screws and my X2 engine has M6

Heres what happens when you stuff a M6 bolt in a M5 hole so be careful.....I got it this way..After I removed the screw I drilled and tapped both holes to M6

CAM2 please excuse my ignorance, but what's the difference between a cateye and an x2? Can you tell me what mine is? Here's a link to my pics:

The cateye engine looks similar but has differences.....The cateye engine has a coil with wider mounting holes and the e-starter is a bit different aswell as has a grey fancover case..........

The X1/X2 engine has a red/orange fancover case

Ok so I got the bolts to my exhaust but now I've got a bigger problem. My black fuel line(not the clear one) was leaking a lot where it connects to the carb. So I cut a half inch off the line and tried connecting it again but no luck, seems like I'm gonna have to get new fuel lines or do you guys know of another cheaper/faster way to get it to connect to the nipple of the carb?

im not sure why they do, wouldn't it be so much easier for not only the consumers, but the manufacturers as well for the sizes to be the same....

You should upgrade those lines but I used a small/Micro Philips head screw driver spun fast in the hole to friction heat it up and streatch it.. Then i was able to squeeze it on... Just a temp fix but can work for that old hard line... After doing that let a second or two of gas flow tru the line so it fushes any plastic out..

Cheers!

Thanks n!pples, I tried that but fuel just keeps coming out of the line. Can anyone tell me which fuel line kit I should get from the following?
http://m.homedepot.com/s/fuel lines/

PB Parts online in Florida has the 2 line kit w/ strainer and rubber gromet for the gas tank, $5.95. The new heads have 8mm studs out of the head exh port, the older small bolt ones the exhausts where breaking off port from the head so they beefed it up, plus there only 46cc w/ a 42.7mm bore but sold as 49cc.

So mine's an older bike then. Any idea what year?

Update on my bike: So I replaced the black fuel line cuz the old one was leaking but something weird happened. With the old one it would start on the first pull now it takes about 7 pulls to start it and I have to give it a little throttle? Think I may have damaged/flooded my brand new carb?

NOOooOo don't order yet!! Read!! ... Our engines come with a little tube that is about 1 inch long. It connects the gas line to the carb. In other words, that "adapter peice" connects to the carb which then connects to your gasline. I'll post a pic in a few minutes

Is that why it's harder to start the bike now? I just replaced the black fuel line with a new clear fuel line I bought at john deer equipment.

Good call, I have pushed smaller clear gas line into bigger gas line before to change line size, works pretty good. Make sure you push the primer bulb a few times before you start it.

So the smaller fuel line can still do the job? Will it affect its performance?

The small line is better, big line may keep the carb fuel pump from working right. It pumps gas out of the tank that's why there is a return line,lol. Most other bikes Cags, Blatas, Polinis, even my 4 stroke 110cc X18 is a gravity feed system. Same with the pulse hole in the carb and manifold if you drill it bigger than 1/8" you might lose pressure and it may not work right.
