G-man

It's a horse skating a half-pipe.

Howdy, boys. Oldgit, I tried all sorts of combos, not twisting the throttle, twisting it 1/4th, with choke, sans choke, all that stuff. Wacky bike, but man, when it finally starts, it runs fantabulous! Jim, what's TTCB? It is a 2 position choke, either on or off. I took the choke intakes apart and cleaned them thoroughly, so I dunno. I gotta take the carbs apart to do something with them jet needles, so I guess another cleaning won't hurt. Did you...uhh...hmmm..mention...WD-40?!!! Sorry, long standing inside joke. I actually have a WD-40 on chains thread floating around here somewheres, but Oldgit says he prefers to use it as his secret ingredient in salad dressing.

Naw man, she won't start at all with the choke is what I'm saying.

Yup, tried there already. Alas, no XS360 anything there. Oh man, this has become an insurmountable obstacle, I tell ya. I called the yamaha dealership today. They couldn't track it down by the mikuni spec number, but did find the yamaha parts catalog number...and it's discontinued. And, no available cross reference for a comparable needle replacement. His advice was sniff out the needles on ebay.

Can you translate that? I dunno what's wrong with the choke...I cleaned those carbs out well, choke included, and don't sense any leaks. So I dunno what da fuck's up wit it. Actually, lemme correct that, probably if she's too lean for a cold start, a working choke would probably help out, true true. But you know, the bike used to start no problem, with the same choke issue. So, I dunno. I'd hate to sacrifice the now crisp throttle response for a quick start, but damn...my right leg is eventually gonna throw my balance off with all the exercise it's getting.

I got your carb thread right here, buuuuuuddy! So, this of course goes out to the usual suspects. I've replaced my ratty stock filters with uni socks that I run behind the side panels, but without the air boxes. I raised the needles one notch to match the increase in air intake. I synched the carbs, adjusted the pilot screws. The bike runs great now, very responsive, smooth at all throttle positions, all that stuff. The one thing though, she's become a tyranical bitch to start. I now have to kick the living crap outta the kick start till she'll finally turn over. It sometimes takes me a good 10 minutes of kicking her until she's finally start up. Once she's started though, everything's great. And, she starts up again no problem so long as the engine is still relatively warm. This is a new occurance since I did all that stuff above...before she ran kinda crappy, but at least she would always start on the first few kicks. Any ideas? The plugs paint the same picture they always have, the right one is clean, left one is kinda carboned up. I found some gas tank crap clogging the right fuel intake that I thought would resolve that. But, there's also the left needle that's badly worn, so I figure she's a bit rich on the left side from that and outta be sorted out when I'll replace the jet needle. Also, I had to turn the pilot screws out quite a bit to get the best idle, so am thinking to move the clip on the jet needles back to the center slot. Could it be that she's now too lean for a cold start, but perfect at running temp? One other thing I should probably mention, the choke is totally worthless on the bike. Always was since I got her. Matter of fact, the choke will kill her when she's warming up. The procedure handed down to me from the previous owner is to turn up the idle with the idle screw when she's first started, and turn it down as she warms up.

Naw, no luck with Speed & Sport. Thanks for the help, boys.

So Drewp, where u get all them part numbers from? To add confusion to the mix, I looked up the yamaha part number for that jet needle: 1L9-14116-21-00. I guess I'll try the yamaha dealership next.

Naw, they're worn out enough to warrant replacing. On both carbs somewhat, but especially the left one.

Hey Drewps. Yeh, I saw you post that on another thread, but I can't find 4fp21-3 needles anywhere (a google search directs me to that one thread). I did go to mikuni, looked thru some of their destributors...lotsa needles, but none with that number. Where did you get those numbers? Here's the biggest list of mikuni jet needles I've found thus far: 4J13 4J13 $3.95 5DP7 5DP7 $3.95 5FP17 5FP17 $3.95 5L1 5L1 $3.95 6DGY04-59 6DGY04-59 $3.95 6DH2 6DH2 $3.95 6DH3 6DH3 $3.95 6DH4 6DH4 $3.95 6DH7 6DH7 $3.95 6DH8 6DH8 $3.95 6DJ30 6DJ30 $3.95 6DP1 6DP1 $3.95 6DP17 6DP17 $3.95 6EJ12-55 6EJ12-55 $3.95 6EJ12-56 6EJ12-56 $3.95 6EJ12-57 6EJ12-57 $3.95 6EJ12-58 6EJ12-58 $3.95 6EJ12-59 6EJ12-59 $3.95 6EJ12-60 6EJ12-60 $3.95 6F4 6F4 $3.95 6F5 6F5 $3.95 6F8 6F8 $3.95 6F9 6F9 $3.95 6F15 6F15 $3.95 6FJ40 6FJ40 $3.95 6FJ41 6FJ41 $3.95 6FJ6 6FJ6 $3.95 6FL14 6FL14 $3.95 6FM46 6FM46 $3.95 6N1 6N1 $3.95 7DH2 7DH2 $5.50 7DH3 7DH3 $5.50 7DH4 7DH4 $5.50 7DH5 7DH5 $5.50 7F6 7F6 $5.50 7F7 7F7 $5.50

Anyone know what size jet needles are on my XS360, and would MikesXS carry them? Or, any other source, for that matter?

I dunno, but Oldgit has some funny used for wd-40 when it comes to his meat.

I got a bullet fairing that I strap on every so often:

Yup, that's what happened to me. Strip the petcock, Gnash. Make sure the little o-ring on the plunger is intact, and the diaphragm isn't ripped. Oh yeah, make sure the spring is ok.

You ain't a real man till you fry a steak in it.

I know a girl who thinks of ghosts She'll make ya breakfast She'll make ya toast She don't use butter She don't use cheese She don't use jelly Or any of these She uses va..a...aaa..seline Sorry, couldn't help it.

Hey, nice bikes, Merv.

Hey, I dunno if this will help y'all, but here's what I stumbled on. I stripped the carbs, pulled the needle valve assembly, and woohoo, lotsa junk behind the filter screen, evidentally gas tank crud, probably got there before the previous owner installed a gas line filter. So I figure the gas supply was restricted into the right carb, backing up into the left one. That may explain (in my case, at least) why the right plug showed it running a bit lean, and the left plug rich.

Lucky you, wish I could say likewise. Paul, I'm going thru exactly the same thing as you, same side as well. Gonna try swapping the plugs and see what happens. Here's a link from a beemer website on an easy-to-build carb synch tool out of a length of tubing and a ruler: http://www.airheads.org/content/view/183/56/ You could also make one with 2 bottles, with stoppers, more hoses...more labor intensive, and I'm not for sure if it works any better.

I found me an XS400 center stand on egay that fit my bike. There's usually a few of them around on there. I think most are compatable, but I'd ask them for some basic dimensions if I was you.

Moi!!

Haha, glad y'all liked it. As for me, totally went over my head till the myxomatosis thing was explained to me, lolz. We don't know much about it here in the US.

...as for my fellow yanks be prepared to offer blank stares, haha. The rabbit and barman A rabbit walks into a pub and says to the barman 'Can I have a pint of beer and a Ham and Cheese Toastie ?'. The barman is amazed but gives the rabbit a pint of beer and a ham and cheese toastie. The rabbit drinks the beer and eats the toastie, he then leaves. The following night the rabbit returns and again asks for a Pint of Beer and a Ham and Cheese Toastie. The barman, now intrigued by the rabbit and the extra drinkers in the pub (because word gets round) gives the rabbit the pint and the toastie. The rabbit consumes them and leaves. The next night, the pub is packed, in walks the rabbit and says 'A pint of beer and a Ham and Cheese Toastie, please barman'. The crowd is hushed as the barman gives the rabbit his pint and toastie and then burst into applause as the rabbit wolfs them down. The next night there is standing room only in the pub, coaches have been laid on for the crowds of patrons attending, the barman is making more money in one week than he did all last year. In walks the rabbit and says, 'A Pint of Beer and a Ham and Cheese Toastie, please barman', smiling and accepting the tributes of the masses. The barman says, 'I'm sorry rabbit, old mate, old mucker but we are right out of them Ham and Cheese Toasties'. The rabbit looks aghast, the crowd has quietened to almost a whisper, when the barman clears his throat nervously and says, 'We do have a very nice Cheese and Onion Toastie'. The rabbit looks him in the eye and says, 'Are you sure I will like it ?' The masses bated breath is ear shatteringly silent. The barman, with a roguish smile says 'Do you think that I would let down one of my best friends, I know you'll love it'. 'Ok' says the rabbit,' I'll have a Pint of Beer and a Cheese and Onion Toastie'. The pub erupts with glee as the rabbit quaffs the beer and guzzles the toastie, he then waves to the crowd and leaves .... ..... NEVER TO RETURN !!!!!! One year later in the now impoverished public house, the barman (who has only served 4 drinks tonight, 3 of which were his) calls time. When he is cleaning down the now empty bar, he sees a small white form, floating above the bar. The barman says, 'Who are you ?' To which he is answered, 'I am the ghost of the rabbit that used to frequent your public house'. The barman says, 'I remember you, you made me famous, you would come in every night and have a Pint of Beer and a Ham and Cheese Toastie, masses came to see you and this place was famous.' The rabbit says, 'Yes I know'. The barman said, 'I remember, on your last night we didn't have any Ham and Cheese Toasties, you had a Cheese and Onion one instead.' The rabbit said 'Yes, you promised me that I would love it'. The barman said 'You never came back, what happened ?' 'I DIED', said the Rabbit. 'NO!' said the barman, 'what from?' After a short pause. The rabbit said... 'Mixin'-me-toasties.'

Don't mind me, sometimes I'm retarded.
