XS400 DOHC weird problem
sorry, didn't explain very well.. no, the vaccum pulls a diaphram in the petrol tap, which opens up the fuel flow into the carbs. you said the fuel filter had a rather low level and when you went on to reserve it ran fine!!!

check the fuel tap bowl for crud, it might be that and the starter forcing the fuel to flow via the vaccum system!!

Dealing with Rust
if you go that route use a proper motorcycle powder coater like triple s or grifs reality works. they are really not that expensive and do know their stuff. I tried a local powder coater and it came out shit.

Oil change on an xs400
need to keep the oil clean as the cam runs in the head, no bearings!! make sure you use yam oil filters as after market stuff can impede oil flow. give the engine a good degrease bfore to take off the oil cover or you will get crud in the engine. If you are just replacing the oil its 2L if replacing the filter as wel its 2.3Litres drewps

NW200 the story
we're up at 8am sunday morning and its till windy as hell. damn we're riding into the wind. Coyles missus cooks us a big breakfast and i end up playing "postman pat" and "we're going to the zoo" on a Pink guitar!! over and over again!!. 9:30 time to go, we say our goodbyes and set off to Armah (Where the Sparton was from) to fuel up. Armah we fuel up at a little petrol station after fuel we start the engine......except for dave on the VFR the batteries flat and won't turn over the bike!! Dave panics, but we say bump start, but Dave wants non of it. So I get Mike on the bike (after taking off the tank bag) and we bump start the bike. It starts no problem and we tell dave to keep his lights off to charge the battery. We get to Belfast no problem and there's no rain ...YET!!. this is the scene that greets us at the ferry terminal there's us near the rear right. Dave wants to be at the back so we can bump start the bike and bump it back off the ferry at the other end. It takes 1/2 hour to get on the ferry and it was looking like we might not get on as the crew were counting and re-counting the bikes, so we panic and jump the queue. ( we all got on, even a van at the end) we tie down the bikes and one of the crrew says that they have a battery booster for Daves bike which relaxes Dave for the journey. When we get to Stranrar it is teaming down and funny enough theres quite a few locals out with brollies watching the "parade" of bikes comming ff the ferry!! I saw an RD400 in yellow and we exchange a few words and wave each other off. I get fuel, dave stalls his bike ( bump again), than stalls it again ( Bump again!) and we;re off. The F#cking rain is bouncing and doesn't let off till Dumfries. my Boots have a lake in then, my top clothes are soaked through, only my legs are dry. I'm freezing and the guys have a pop at me for not stopping earlier than Dumfries. I just wanted to get into some KFC/McDons to warm up and strip off the wet stuff, rather than shiver in a pokey cafe!! We find a KFC and dave finds a closed bike shop (scot-speed) which was closed funnily enough (twas Sunday Dave!!) I proceed to strip off in KFC and no-one bats an eyelid, put me warm clothes back on and come up with some new water proof fashion. Debbie Harry inspired clothing Givi Tescobag socks (taken at home) Saited and dryish, we set off via Gretna and head for Penrith keeping to the A roads, it starts raing again so we dive into the local Maccy D's Penrith castle from McD's we're looking a bit worse for wear now and looking at Mike I can only guess what I look like after Penrith, we go to Tebay for fuel and coffee, head back on the A road to Kendal on some of the most amazingly smooth and traffic free roads and onto the A65. The rain has stopped and it feels much better and gives us the reason why we ride bikes and not drive cars!! Dave lives in Leeds, so we say our goodbyes and Mike and I are knackered and just want to get home, so we hit the Motorway and dial in 70mph and we only stop once at Bolton west services. I eventually get Home at 11:30pm, so thats 14 hours travelling and at least 10 hours riding!! My bike never missed a beat in spite of the weather!! and I only spent £70 in fuel for 620 miles pretty good mpg!! ( filled up 5 times going and 5 times going back @ £7 (7 liters a pop) would I do it again? well,I left the final part till a week later to answer this and I would say yes, but I would get the Birkenhead ferry next time or get a bigger more modern bike to cope with the distance.

1979 XS400 stops running when tilted level... WTF?!
check float levels, tilting bike affects the right carb, so it could be flooding or starvation. either way I'd strip the carbs down. drewps

I think I am turning Cafe, I really think so
did you adjust the pilot settings, it only takes a few turns to effect a result. I rebuilt my carbs last month and couldn't stop the hanging @ 4k till I messed with the pilot screws adjustents

its usually the little needle valve that goes you canget them from ebay or sirrus consolidated. easy enough to do, but you need to take the carbs off the bike first.

Loss off power half throttle and 6k+ RPMs
do the air pistons the diaphrams attach to, move freely in the bore? you also need to pull the diaphrams a bit to see any tears. If you have the carbs off, take out the mains and see if the emulsion tube is clear. there are tiny holes in the side whch can block easily. the emulsiin tubes come out through the air piston side after undoing the main jet. it just taps out. dont turn it as its keyed!! drewps
