Barcus

Thanks for sharing all your info. I recently used Motorsloop for the very same thing... thanks to you. I now have the right side engine casing on its way. Fedex no less. Terribly exciting......

The, almost, stripped frame. I started to wire-brush some of the paint to make sure there is no corrosion underneath. So far, so good.

Nice pics. Thanks for sharing.... My rear wheel back on... bloody stiff to turn.... what you reckon? Bearings? The oil defo needs changing... been stood 2 years.

Sorry Barcus, can't help you with a collector box but I might be looking too in a few months as my one is rather tatty looking. If you are going to take the engine out and do a rebuild, like me, you have to enjoy the challenge and not do it in a rush to get the bike on the road. Go for it though, and rest happy in the knowledge that you are probably saving it from the breakers yard.

Thanks anyway. I have cobbled together an old 4 into 1 for now, but am loathed to sell on the silencers and downpipes just in case something turns up... Do you know whether the XJ550 750 boxes are the same as the OEM xj900f box (long shot, but who knows...?) Thanks for replying.

Hi..

Any advice on where I can get a replacement collector box for my XJ900f 58L 1986 model? I have drawn blanks anywhere in the UK so far and it's driving me nuts. Not sure whether there are any other models' collector boxes which will fit... can anyone please advise / help me? Thanks.

Hi. I am reached a hiatus in progress with my XJ900f restoration.... I need a collector box to fit the 900 pre diversion. Drawing a blank at the moment. Can you advise me: do the boxes from the 750. 550 fit the 900 as well? Thanks for your wisdom.

Hi. I also have the same model. So tempted to take the engine out and clean up. mechanically it is sound. I have a real problem to find a collector box replacement... any ideas?

Try Bridgestones. or Continentals.

just toured the lakes on mine,but with not so much luggage, awesome, great bike i love it, should have bought one 20 years ago

I have a Rentec rack for the XJ900f. I won't use it. Do you want it? I'm advertising it for £40

Hi.

I have had several XJ600 pre diversions. and now have an XJ900f 58L (1985). She's very tatty' but I've been spending a lot of time on her... Just replaced plugs and filter and new fuel in a slightly leky tank and guess what... she started second push of the button. I was amazed! Carbs were off and cleaned out and butterflies freed up and she fired up instantly. So now time to do the rest... My tank has been lined in the past and was full of floating skins of some deteriorated liner. So I was interested in your blurb about tank liners....

My main thing at the moment is the exhaust.... I have sourced replacement downpipes for £30 and the cleaned up really well and are solid (the original ones were totally rotted) ' the silencers are called Jawa and seem in good nick' but the collector box was falling apart and totally unredeemable. Can I find anther collector box? Can I hell! Wemoto do sell something new as a replacement. but it looks like the diversion box (which I bought in error and definitely does not and cannot fit). My question is: are there any other models whose collector box will do the same job and fit the XJ900f? I've seen a few Maxim XJ550 boxes for sale in the States and the XJ750 also looks the right shape and length. Do you know whether these will fit?

Thanks for reading my message and your reply if you can help / advise. On the up side' the XJ900f is looking set to be fab.... far lighter and easier to move around than the Divvy 900.....

Bought a 91J Yamaha XJ600 pre-diversion a few months ago. Sorted carbs brakes, coils replaced cables and so on and on and on..... bloody hell! Can't believe how much time I've put into it (and dosh). Anyway, running like a dream with new oil and plugs and air filter... ACE!! THen the shit hits again....... new battery is FLAT. AA man came and said he thinks it's the rectifier. £65 from local Yamaha dealer / £45 from Wemoto. First though. Are there any ways of testing the integrity of the current rectifier on the bike at the moment? as it would be a shame to buy a new part and find the same problem. ANY advice welcome and very gratefully recieved... Cheers. Justin

Sorry... Thanks for the pics. I just realised I replied to you, but in the wrong name.

Yours has the original mirrors and indicators... both of which I prefer.. but mine has a rather longer screen which deflects the wind straight over me heed.

I'll take her out for a spin before she leaves home.

All the best.. Justin

Hey Barcus, good to see another XJ600 pre div owner on here!

they can be restricted and im pretty sure most parts are still available through your yamaha dealer (they may even be willing to fit it for you) failing that the kits sometimes appear on ebay but will need the certificate (again, a dealer or M/C garage may be able to help you out).

ive never bothered restricting mine and never had a problem, only some insurance companies request to see the restriction certificate.

EDIT: just out of interest what mileage has yours got?

30k miles... what's yours like? any pics to make me drool.?

Cheers for the info mate. I love my XJ... so not too bothered if he doesn't want it (but seems rather keen.... bugger!)

I'll pass on the info to him and send him your thread too....

Sounds a lot of wonga for a few piddly washers.... bit of a stealth tax (yet again).

My XJ is a 1989 (F plate) 51J model with 30k original on the clock. She looks VERY pretty and goes like a nympho with her drawers on fire.

I have only once taken it to the local airfield and clocked 120mph on the clocks (so probably not too accurate). Otherwise, I tend to razz about with the wife (until she became preggers again... Hooray! Been trying for bloomin ages) around the country lanes of Norfolk. Love it !! I'll be sorry to see her go, but there you have it.

CHEERS FOR THE HELP>>>> Al,m the best..

Hi... I am after some advice.

As the wife is expecting our 2nd nipper, she's gone off the boil on the bike outings (SHAME!) so a local lad has expressed his interest in buying my XJ600f 1989 pre-diversion. Only problem is the bike has 72bhp and he needs to restrict it to 33bhp... is this possible with this model and if so, where does he get the parts from? How much will it cost?

THANKS.... You are always a mine of info. on the site..... I love my bike, but she's going, going and nearly Gone.... (I AM offcially very sad!)

Hi everyone.

I am relatively new to this type of forum stuff, so bear with me... I've been reading quite a few topics though, and it seems a great system for sharing ideas and info.

My problem / issue is this:-

my bike starts fine and goes well, but occasionally, she will simply die in mid-flow... It is as if I have turned the engine off. It's quite like a fuel starvation, but I know fuel tap is on etc...

I have noticed that the kill switch on the right handle bar seems dodgy... sometimes works and other times nothing but a click. Then, after a few momoents standing, and several clicks on the kill switch... off she goes again with no problems until the next time it happens the same thing! The fuse box seems to be held together with blu-tac! Not sure whether that would be a problem, but want to replace that with a good one with all contacts etc in good order (so if anyone has scrap one to sell, please let me know). I am unsure whether this is elctrical or fuel starvation, but seems I should explore those avenues which seem most apparent first.... ie... kill switch and fuse box. Please let me know what you think.

Also, my engine (29k miles) seems pretty rattly (although the MOT guy said it was fine) so I wondered if anyone could advise on tightening / adjusting the cam chain tensioner? Does the tensioner do so automatically on these or do I have to unscreww the bolts and do it manually? Should I adjust with the engine running so I can hear the difference too? Thanks for your comments in anticipation. CHEERS. Justin

Hi.

I just read what you said about your XJ and oil overfill....

I have recently bought a 1989 pre-diversion and think it is over filled since I can't see an oil level in the window of the engine casing.

What happens if it has too much oil? Mine also rattles a fair bit, but goes well until (now and again) it just dies in mid flow.... as if the engine has been switched off. Then; after a few seconds of stand still/ or a minute and a flick flack of the kill switch and she's off agaion. Do you think the switch has dodgy contacts? If so, would that do this to the running engine? I guess so eh?

Mind you... how DID you get 130mph out of yours. I got to 120 on the clock and shit myself, so sloewed down... don't think she had much left in her though.

I would appreciate your thoughts on the electrical / fuel issue and the oil level too... Cheers. Justin

Exactly the same model as I have.

Let me know how you find it... Just started riding this after some 20 years away from road bikes... nippy little number.

seems pretty heavy for such a small bike though. How are the electrics on your XJ? My fuse box is held together with blu tac and the kill switch shorts as you ride along, but other than that, she's a blinder... Put a bloody sensible pair of horns on though... the standard OEM horn is pants... Now has 139Db blasters, run off a relay... Hmm! That should make 'em sit up and listen...

I am assuming that the head is made of Aluminium on the Pre-Diversion XJ600f...?

That said, three fins on the left side of the head (on mine) are snapped and generally buggered well and truly.

I'd like to think there is a way of repairing these for cosmetic appearance alone... The damage makes no difference to the running of the engine... just looks pants on one side. I guess the previous owner didn't give a hoot, but I am a bit more fussy.. Mind you, I don't feel up to changing the head, so any suggestions would be appreciated....

Cheer Ears

Well I'll be....!

Only had this bike a few months... MOTd etc.. and happy going along until suddenly the bike lurches forwards as if no fuel.

Plenty fuel me thinks, so wha' the F....? Now I remeber the time when she would not start after I had switched the run switch off and on again. There was an electrical shrt (fizzing )sound when the switch would not engage as it should... contacts stuffed I guess. Anyway... On, Off, On, Off and then the switch engaged and she fired on the button again. Am I right to assume that the switch (if dodgy contacts) could be the culprit? This has happened twice now... Not so bad at 10mph, but at 110mph (as yesterday) I know... Woops! This was not on the roads... Honest, Officer. At speed, it's not too clever.

Do I need to replace the switch altogether, or is there some quick, economical and safe fix?

Cheers ears...

I can only say from when I used to own a Honda CX500 (The plastic pig) and used her for dispatch while I was a student, that the shaft drive is great... very responsive and immediate translation of power from the crank. The CX was a very torquey bike, not glamorous nor fast, but always pumped out plenty of grunt from low revs. I found , with a shaft drive, you could slow right down in top gear, to almost walking pace, then squeeze the throttle and she'd push away immediately. The advantage being that you don't keep changing up and down the box in traffic and so reduce fuel consumption.

Shaft drive doesn't really affect the ride, but if it does lock the back wheel up, just throttle down and ride out of it... after 10 years riding, you can do that no problem and it wouldn't be half as bad as you are thinking anyway... probably just a split second or two.

Hope that might help. Enjoy the shaft experience... you'll never want a chain drive again.
