Need a new reg/rec for me 900A4 Blew main fuse last ride out when giving it the beans! What’s best & what’s discount code for ZPower? Hi Piggy .........a combined Solid State unit is by far the best ...not sure where best to buy it "probably @ your local bike breakers) , you'd have do some...

Old ( v-bad quality) pic's = taken 1978 of me , my Ex & my old Z1B CR-Cosworth 998cc Stage 2 . A beast back then & a Pussy Cat by todays standards !

Any one else have problems with the nut that holds the front sprocket keeping coming loose on a offset sprocket? The thing is the spline doesn’t come through it so the tab washer doesn’t do it’s job. Brian, Perhaps try this ....take the G/box sprocket off & take it to a Toolmakers / Engineering...

Just been discussing carb issues with Steve Smethurst and he suggested I use Champion copper core plugs. Does anyone know the equivalent to NGKB8ES? Cheers Mike Here we go ........my 2 penith is ....Never had issues with B8ES's in 44 years of using them , having said that I'm now ( last 2 years ) b...

cheers i will try but carb cleaner seems to come through fast in every orifice its got 17.5 in standard i believe If you have Std Mikuni 26mm carbs the 17.5 pilots are correct for a Z900 and you should not require any larger than that ! If the bike was mine I'd check your plugs & caps are all O...

Hi All I have a 72 Z1 900 and I am looking to set the camshaft timing. I don’t have the original advancer unit for it. I am using the following advancer unit (see attachment). Can anyone tell me what timing mark I should use when pistons are top dead centre. Thanks Irishkev Hi Kev, personally I'd r...

they should have an open hole at the base of the muffler about 4mm in diameter Yeh ...i think your spot on there . But you go back up the lowest 6 O'clock point of the out silencer skin, about 6-7mm and drill a hole there at 6 O'clock ...reason that is the point to drill is because I believe there ...

Hi I am having problems with my UK 76 Z900A4. I restored it a few years ago and up until a few months ago had been running fine. It is in standard build with original 4 into 4 pipes, carburation, air box etc. It is however, fitted with a Dyna S electronic ignition. The problem is as follows: Bike s...

Is there anyone making these washers? don't think they are available anymore Its the double tab washer that goes under the throttle slide adjuster on Mikuni VM 26s Part number 16054-008 Hi Wayne, nip down your local hard wear shop & buy some thin sheet- tin or brass & make 8 up yourself ......

Easy way to bench sync without mucking about with bits of metal bar under the slides etc is to set all your slide adjusters midway on their travel and level the slides to the top of the carb bores with the throttle open. Once done you need to vac balance to get all the cylinders working equally. On...

Hi ZedHead, thanks for the info over the past few emails I've posted. Any ideas what would be a fair price? I'd rather sell to a good home than make a profit. Owned by myself since 1992, hundreds of receipts kept over the years. Engine is 1075 Wiseco, HD valve springs, APE valve spring retainers, c...

Hi, my bike which I have owned for 22 years is playing up, I think. It leaked oil from the Ginny case over my boot so I decided it needed a new rubber bung and a loon from z-power. I had to use my own connectors as the supplied ones are too small for the wire. Anyway, I suspect it’s not charging as...

Hey, when are the shim buckets worn out? Do they wear out? Have some discolouration and slight scoring on the sides, imagine that’s normal wear and tear? I've never seen any spec related data on bucket & bore i/d & o/d tolerances . I personally would not expect to see any either, as the con...

Thanks guys - Been looking at the CTEC XS 0.8 at about £60 so anyone used one of these ? Hi Alan , I bought a new CTEK- MXS 5.0 4.5 years ago so I can only comment on that model........ but it's been outstanding ! I use on it religiously on both my lead sealed & unsealed & sealed AGM batter...

[quote="davidcouzens"]hi all many thanks for your replies, i shall measure the mouths and the dowels, they can be removed and go from there. the engine is z1e-106324 i think dated early 76, the oil capacity is visibly cast on the top of the crankcase clutch side. the engine is out of the f...
