thanks drew. not sure what to do yet, whether to buy bowls(40 + from usa), and try them, or buy the correct !!! set(near 200, from the usa).

well I've been doing some searching, and discovered that there off a 80/81 xs400, and found bowls to fit, but will these work ok, I wonder. the jets in the carbs are correct for the bike, but not sure of the slides. also found 3 sets of carbs, correct for the bike, at 145. including shipping/postage from the good old US of A, and will have to strip and clean.

thanks drew I thought you would come to the rescue. graham

Hi peeps. I have a 78 xs250 I restored, from early on, I intended to convert to a 400. I purchased a set of 400e carbs(well I was told they where, or sold as) some time ago, any way, after stripping the motor, and commenced the change over,that seamed to go ok. and now got to the carbs, something is not right, it appears, its either the float cover chamber is wrong or the carbs. on checking the parts book I have,the part No.2A2-14984-01, which didn't look correct, so had to order p/n 2a2-11351-00, with the hole in it.. the float chamber I have looks like the correct, from the Parts book. so can anyone shed any light on this, please check photos. PS hope it all makes sense. thanks graham sorry unable to edit with an arrow.the first , bottom right hole, not the screw hose.

Ive got a new valve for sale, but not sure if exhaust or inlet. if your interrested, i will check. graham

I don't think you pay import duty on used parts.

Thanks drew, u's the man, what would we all do with out you. I've never seen a wiring diagram like this, it's not in the 3 workshop manuals I have. where's it from. by the way, you've done a excellent job with the flat tracker, been following your brog. thanks once again, very much appreciated. graham

Hi Drew, thanks. I know, take more than you think you need. I just need the route of the wire, the connection are straight forward, !!! graham

Hi all, Help needed please with the wireing route on my 1978 XS, as you can see, i've started the rebuild approx 6 months ago, just haven't had the time to do more. I am now stuck on the correct route of the wireing loom,can any one give the right route (left/right, over/under the frame), either words and /or with pictures would be great help. I have started from the back, tail light,fuse box ect. graham just put new clutch plates in, and re-zinc plated the kick shaft. I've spent about grand on the motor alone.

Hi wayno m8, you could be my saviour. I need 2 main stand bolts,(with lock nuts) as I can't get the correct size dia 14mm, I’ve got 2 sets of yam replacement parts, they are 12mm dia, so no good. All so, could do with side stand bolt,nut,washer, and 2 f/foot rest pivot pins,washer l/nuts. could you machine 5 items in stainless steel. So, what do you thank, can you do it, and the cost. Thanx graham

were you thinking of this 1971/72 GL750 2smoker, 4cylinder, water cooled, which never want in to production.

Hi all, help needed again, I am planning for the rebuild of the engine(78 xs), and wont to get every thing ready before I start. I love using a locking adhesive on nuts and bolts. So the question is; what do you use , if anything at all, on con rods, and any other engine nuts/bolts,(crank case).

I hope this helps, my 78 xs250 and 400 has 7 friction and 6 steel plates, I also looked at http://www.cmsnl.com/yamaha-xs400h-1981_model8825/partslist/C-02.html. 81 xs400 showing the some, so I guess yours should do as well.

there are 2 on ebay now,My link My link

niggs if its part No. 1L9-11186-00 then, its availible from here My link if you cant find it in the UK. graham

Thanx once again drew, that stuff looks amazing, and I will definitely order some, knowing me I will probably melt the carb.

Thanx drew, u's the man. It didn't look like they where washers, mind u my eye site if crap these days even with reading glasses, if I looked at the diagram I up loaded, I would have seen them. 'Dow' ( if I had a brain I would b dangerous,) Both washers where a pig to get out, so was all the other jets, all screw driver slots where chewed up, I didn't help the situation either, had to use a reverse thread extractor to get them. And this had to fricking happen. Is this possible to repair or is it a bin job and source another one, if so, is there anyone out there with a good right hand carb mikuni BS34 for a xs 400.

I am also restoring a 78 xs with OEM parts where pos, after being off road for 12 years, items 2 date not yam stuff is silencers,s/steel calliper pistons, shocks,some nuts/bolts/washers, brake hoses (purchased from classic brake hoses). Not much more to get now after 3 years of collecting. About to start the rolling chassis with the engine going in last. graham
