I assume your talking about the 2A2 engine, as there was a later dohc engine which won't fit. the xs400 will slot straight in and is in fact lighter than the 250 (bigger bores I assume) you can't just overbore as the valves are a lot smaller and uses a different carb 32mm-250 34mm-400. I think even getting a 400 barrel onto a 250 bottom end could cause the liner to foul the crankcase mouths (not tried it, but i'm guessing) I bought a 400 engine off ebay for £50 and carbs for £20, then you need the rubber between each side of the carbs for the bigger mouths. Well worth the hassle though as mine motors up to 85 and great on the twisties. a custom model will fit as its only got a rounded barrel as opposed to a squared off one. Be careful of the 12n model as they have "rear sets" which If yours hasn't then you need to figure this into your equation. BTW loads of stuff in germany, but be carefull with carbs and camshafts as they have restricted (27bp) engines drewpy

I'm thinking; Flying time and CAT B write off

Go for it, if you like the bike its gotta be worth it. over 15 years old is considered a classic nowerdays!!

Have you tried ultrasonic cleaning? I used JRS and cost £100 for a pair to clean.

quickens the steering at the expense of high speed stability

its the union flag not union jack.

don't fortget to break the seal first on the rim. I run my car over the tire slightly and you can hear it crack. otherwise you can't get a lever in.

My understanding is that emulsion tubes are the tubes which the needle runs in, Jets are screwed in at the end of the tubes

sounds like timing to me, I put my thumb over spark hole to get feel for the compression then I know the timing marks will be tdc.

yamaha only made xs240, xs360 xs400 xs500 xs650 (twins) xs750 xs850 (triples) and xs1100 (fours). no such thing as an xs600 need to go back and find out which it actually is. may be get the engine number, number of cylinders would also help.

no problem

Get yourself a manual and read it. Haynes should do one for your bike and it tells you what needs doing at what intervals and how its done. That's how I learned.

Smartarse

shag was also a pipe tobacco

are there resistors on your LEDs? maybe the relay has them also so that the extra resistance will lower voltage enough to cause the symtoms you describe. I am not an electronics expert so don't take my suggestion as gospel!! drewpy

yamaha dealer will have them and speed & sport, bikebandit, motogrid

not hard, you use ebay Item number: 140075701437 put item number under buy section>search german site but takes paypal and I've bought plenty from germany!

you need the registration number. If you haven't got one then you will have to reregister anyway. you need to contact the vjmc and they will help in obtaining an age related plate.

I've since been told autosol was too abrasive so didn't try. I have managed to get 1 nos downpipe and 1 being rechromed as we speak. The nos ones have twin walls to stop blueing. Still looking for a right hand silencer, tried classic bike forum as well. only could offer 3n6 silencer which i already have 1U4 anyone?

never throw anything away, 6 months later and you will want it. I can tell you from experience on that one to turn the engine over, just use the fat black lead from the starter motor (or whatever that colour is) and ground another heavy duty lead from the negative on the battery. Take out the spark plugs first as it will be easier to do this with less compression. Also squirt a little oil down the bores to help lube the engine. I assume that you still have engine oil in the engine and that you are checking it over to make sure its not seized? dont leave the starter on for more than a few secs as it will burn out! I would put the engine on the floor, that way if it jumps, it won't fall off and crush you toes, or what ever is sticking out at the time!!!

There are plenty of spares around, and I would keep it stock as the carburation would be out and especially if you are restoring the bike. The pods do fit straight on the bike carbs, then you would need to change the jetting to compensate for the increased air flow. Fitting bs38's would lose tractability of the bike as you are losing the high airflow on the intake because your using larger carbs. Great if you are racing and keeping the bike in the 9k+ rev mark! BTW for spare carbs, the xs750/850's use the same carb but with differrent jets

have you checked out the batteryeliminator site http://bat-pac.com/compatibility/index.htm says you can with a large capacitor (that's what a bat-pac is) and if you google there's bound to be someone who has found a compatible one from Maplins cheaper!!

space out the front sprocket?. You can get laser alignment tool from MandP to check!
