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.

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 grahamsorry unable to edit with an arrow.the first , bottom right hole, not the screw hose.

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.

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.

hi all, advice on how to remove the existing main nozzle in carbs to replace with new.
item 4 pt no. 2a2-14941-06

Thanks drewpy, I've never came across that firm b4, ( goggle search) I will email or phone them to check if they still do it.
I am going to rebuild the motor last, and pad out the frame. is it right side as you look at bike or sit on.
Yep 110 for zincing, and some have to b redone, they didn't even undo the nuts from bolts so the ends and insides where not coated.
graham
emailed the above, and they have got back 2 me, the cost is £60 + vat. Inc return p&p
-
I put some masking tape with sponge on the frame rails, engines go in/out from right hand side
i think the rd aircooled had a supplier but did a search and couldn't find it!
why don't you use a casswel kit and do it yourself?
drewps
As for the kit, £150+ basic £49.00 if I know what I know now, I would have done.
the first lot of zinc cost me £110. have still more to do, plus the olive drab
The only firm I have found that still do olive drab is Collins Chemical Blacking, surrey.
they gestimate £50. for 31 items, food pegs and washers,clips & screws on air hoses.
I had thought whether to spray sat black(pj1)to save money. (but will it look OK, not authentic??)

SPEEDSHOP-Re oil, I think drewpy answered that one for me, as for the crank & con-rod shells.
I have cleaned and polished the bottom crank case, cleaned & resprayed the top and side covers, had the cylinders bead/vapour cleaned, and the head cleaned and valves reground, so I think I would be daft not to put new in after a total nut and bolt restoration of the bike, and after spending in excess of 1.5K.
The idea was to rebuild the minimum of the motor, not the clutch and oil pump etc. to lay the motor on its side and then lower the frame over, fix in place rather than try to put in a rolling chassis, with the likely hood of damaging the p/coat on the frame, I would prefer this way, but as said above, afraid of damaging the frame.
What do others think of this way of rebuilding the bike, has anyone rebuild this way with no problems.
I have found 1 coater for olive drab finish, but asked for others for there personal experiences,
as I have had some bright zinc coating done, and was not happy with it.
So recommendation I was after.
I have just read on another forum that this firm I used is crap even for there chroming and service.
GRAHAM
thanks.

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).
