Soo. Here I am a fair while after buying my first zxr and it's still apart :/ planned to just give it a service and get the fairings repaired/painted, yet it's still in a thousand pieces. It's the story of my life! haha. A few things I've done so far; replaced front rotors and pads, new iridium plugs and caps, new oil and a brand spanka front tyre and near new rear. New sprockets and chain to go on this week also. And now I need help lol. With the brake lines, I replaced the original ones with some steel braided lines and there's a mega bubble (possibly in the MC no?) in the line and I can't get any pressure no matter how much I bleed new stuff through. My skills can only get me so far, so some advice here would be great please. Also, I heard a rumour that you can fit zx6r f ('96ish I think) calipers on the zxr250... hmm interdasting.. And then I read some gsxr k1 6 pot calipers can fit.. lol I also heard you can fit the 250 Balius exhaust to the zxr250 as they both share the same engine, and I can confirm this. The Balius exhaust is stainless steel and looks shiny (I like shiny) and also has a different 4 into 1 pattern. I happened to find a Balius exhaust on ebay and yes it does fit, but the tab on the end can doesn't line up. A quick grind and flap disc later and it'll accept a normal exhaust bracket. The end can is coming off later anyways, so I don't mind if it looks shoddy temporarily. I cleaned the exhaust up, used some wet dry (360, 800, and 1200), polish, and it looks pretty awesome. I'm not gonna spend heaps of time polishing it etc, but I gotta say it looks loads better than my old rusty piece of metal. Any who, I'd love to get it all back together soon. I'll post in the new showroom when she's done!
Hey edwardo Remember an old saying, Rome wasn't built in a day!! So it's taking a little longer than you anticipated, truth be told it always seems to be that way. You have made progress, thats the good part and the rest will happen, patience my friend. Lets discuss the brake issue. 2 questions, are the braided lines new and did the brake work with the old lines on. Chris and I encountered a similar problem a few weeks back. We couldn't get any pressure on the front brakes, lucky for us we had a selection of bikes in the garage and promptly changed a complete system from a donor bike. Within minutes, problem resolved. Turned out that the master cylinder was by-passing, easy repair. My advise is to have the master cylinder checked, if faulty get a kit and you should be good to go. Exhaust sound cool, different!! Can't wait to see some photos of the finished product, good luck.
It's true, I am being impatient! I have a habit of over thinking it all and it ends up keeping me up all night! Yeah the braided lines were out of the packet. So I was bleeding from dry. And yeah, I just can't get any pressure. I did read that it would probably air in the MC. I'll most likely get it checked out by someone a bit more qualified, I have little experience with this kind of trouble. Any idea where I could get a specific kit? I'll see what google turns up. Yeah I thought so too about the exhaust, it looks to be the same diameter pipe but the left most pipe comes across to the right, probably for aesthetics being off a naked bike. It's a tighter bend than compared to the zxr, where all the pipes kind of merge smoothly. I'd say the Balius exhaust would be the tiniest bit more restrictive in that sense.
Sounds like u have made good progress ...... pulling things apart is easy...its getting it all back together that takes perserverance! Did u follow the guide posted here? http://2fiftycc.com/index.php?threads/brake-bleeding-made-easy.1140/ Are there no leaks with the new lines? ..... did u use new crush (copper) washers or anneal the old ones? Has the MC been cleaned out? ........ theres a very small hole for the fluid to pass thru and can be easily blocked The insides (plunger/seals) of the MC may be shot.....
Yeah I used that link as a guide. New crush washers, and I read about that hole that can easily block. There was a bit of crap in the fluid container thing. I suspect it would be a block as the MC seemed to be fine before.. Tbh, I'm not 100% confident in my abilities, I haven't done brakes heaps before, got a little scared when the breaks didn't get pressure lolol Do I just disconnect the banjo bolt on the MC and just get busy clearing that hole or? Thanks for the help also
After hours of bleeding the Fizzer and getting nothing I found this to be blocked ...... cleared it and bingo , instant brakes! (just gave it a gentle poke about with a guitar string) Make sure u use brand new fluid every time u top up.
I see, I shall give that a go tomorrow! Very clean looking right thar, mine has gunk in it I'll let you know how I fair! Also here are some pics of the exhaust!
Thats a fine set of headers right there! Make sure the inside of the MC is spotless....... there are very small holes in the calipers also so the fluid needs to be new every time u top up when bleeding it thru ..... its cheap so a bit wasted while bleeding is nothing. If u look closely at my pic u will see a pile of grunge in the bottom left corner ..... not good.....that was before a good clean! Good Luck with it!
Hey edwardo Love your work on the headers, they look great!! I'm with you, clean chrome looks great, some BLING Hope the rest goes well, your on the right track mate.
Brake update! I got some advice on the brake which was to bleed via gravity only, no pumping. I was told 99% of the time, cracking the bleeder valve and letting it go into a bottle and topping up the reservoir would clear up problems, the only negative being it could take some time. I did this, and it didn't really do a lot! So on a whim, having read it in various forums, I pulled the brake lever in and tied it overnight- and presto! I have pressure back! Still a bit spongy so I will bleed some more and do the lever trick also.
I don't want to talk about brakes on ZXR's... GGGRRRRRrrrrrrrrrrrrrrrrrrrrrrrr actually Phil and I rebuilt them on our A model, didn't have much luck so last night we fitted new caliper and dust seals, new bleed nipples and we finally have a decent brake. I have a brake bleeding tool which I hook up to the compressor which draws the fluid down by means of a vacuum which normally works, last night we pumped the lever as it was late and my compressor is loud. I have never tried the gravity option.. might have to give that one a go. your headers look sweet, will the fairings fit with those headers and pipe ?
Yes there is also undoing the banjo at the MC and bleeding out there too ....can get messy though . Also u can reverse bleed by shooting the fluid back thru the caliper with a syringe. But as u say ...try bleeding normally again and then do the lever overnight again.
I'm hoping the fairings fit! haha they pretty much take the same shape under the motor and all that so I think they will, I'll let you know once I get the fairings back on (another long story, seems I got burnt buying replacements online). As for the brakes, they work well enough for me to take it to someone who know a bit more lol, that's if I can't get them any better myself. Apparently there are multitudes of ways to bleed brakes! When the guy told me the method I quoted I was like "whaaa?" never heard it before!
*Another update* Did the lever trick again and gave the lines some taps here and there, and now my brakes are rock hard woo hoo! thanks for the advice in this thread!
