Completely refurbishing my GPZ900R Carburettors - Part 3

[@true-moto-resto]

Nice Job! I’d recommend bench testing the carbs with a fuel supply for 24 hours to ensure they don’t leak (gaskets, Orings, float needles). It’s best to discover such things before they go back on the bike.

[@AshRowland]

good idea!

[@Gassit]

Nice job Ash they look great. Only thing I would advise is a dab of thread lock on the butterfly screws, don't want the engine swallowing them if they come loose.

[@AshRowland]

That's actually a great idea, yea, I'll definitely do that

[@peterferryman4905]

You did a job, I'm amazed at how much you are doing on your driveway, and it's refreshing that your wife/girlfriend pokes her head in your videos from time to time 👍👍😎👍👍

[@AshRowland]

Thanks Peter! I'm greatful for the unit I've got the FZR in lol

[@richardwhelan8060]

As that tube you call the jet holder is actually the emulsion tube.. Mixes air with fuel critical off idle... You've done a nice job bty

[@AshRowland]

Ah cool, yea, I was just going with what the manual described them as

[@drcharlestennant8658]

Just came across your channel yesterday - love watching you strip/diagnose/repair/refurbish your bikes - very enjoyable 😀

[@AshRowland]

Thank you! I enjoy doing it, plenty more to come

[@Kurbits]

Nice looking carburetors! Remember that using stainless screws in aluminium causes galvanic corrosion. The screws may get stuck. I also used stainless screws on the float bowls, I put some Never-Seez on the threads, they still come out easily 25 years later.

[@AshRowland]

Thanks for the tip, great idea

[@leon0]

That's a brand name for cooper grease. I agree, I always use copper grease on the threads of stainless machine screws.

[@AshRowland]

@@leon0 ah, I was wondering lol

[@markdavies5508]

So Kate clocked the mess you made when you spray painted the laminate floor in the last vid and chucked you out. Got it.

[@anotherinternetaddict]

I think it was the vinegar on the freshly painted ceiling that was the breaking point...

[@AshRowland]

🤣

[@KensWorldRestorations]

Love the before/after pics at the end. Great job and now you know this part of the equation is solved. You can make your own carb balancing tool from standard vacuum gauges and some fuel line. I bought the vacuum gauges that are filled with kerosene so the needle bounce is dampened. Cool video!

[@AshRowland]

I've got a set that I got from eBay for cheap... they work ok, not the most accurate though

[@XLV750RD01]

To initially synch the carbs on the bench you can use small marbles or ball bearings . Rest them on the butterflies and slowly open the throttles. Watch which ball falls first/faster and adjust accordingly.

[@AshRowland]

That's a fantastic idea!

[@wisecampmotorcycles8258]

Great job on the carbys Ash, been following this build, well done.

[@AshRowland]

Thanks! Hopefully the rest of the bike will work out as nicely

[@PatrickHostler]

I wonder how many hotel rooms have been used for carb restoration 😂 Excellent job I must say!!!

[@AshRowland]

🤣 probably more than you'd think haha

[@vfrbore1728]

Very impressive. Just shows what can be achieved with relatively basic tools, time and a methodical approach.

[@AshRowland]

Basic tools? I think you'll find that my hammer is very sophisticated 🤣 🤣 🤣

[@leon0]

Your approach is great Ash. Somewhere between a surgeon and an artist. More power to you.

[@AshRowland]

Haha thanks, that's quite a broad spectrum... some say I paid Ben Collins to pretend to be The Stig!

[@onlyvintagewatches]

Excellent video. I am rebuilding a Kawasaki ZR 550 Zephyr from 1991, and it uses the same carburetors. I cleaned them perfectly, but never thought to paint them black....

[@AshRowland]

They look good in the bare aluminium to be honest

[@chaosin73]

Carb icing!! Interesting times on my suzuki bandit. Used to buy a fuel additive that stopped that.

[@AshRowland]

👍

[@chrismurphy4724]

Ash, that weight thingy in the kit is the float needle valve that regulates the flow of fuel to the bottom carb bowl when the float rises/falls .. great job rebuilding the carbs budd

[@AshRowland]

Thanks bud, yea I can't always remember things when I'm filming lol, I could edit everything like everyone else but then my videos wouldn't feel as natural 😃

Top job Ash , looking forward to engine build etc.

[@AshRowland]

[@Jay-Ninja]

Nice job Ash, really enjoying the build. I also noticed that you take the time to respond to every comment made - Very admirable, although as your followers grow it’ll become a full time jn itself.😂

Haha well spotted... its nice to be able to do it to be honest, and I'll continue to do it as long as I can, when I get a billion subscribers it might be tricky 🤣

[@shaunhardie6077]

Cracking job on those carbs Ash, just one little thing, did you apply any "Thread lock" on the tiny screws holding the butterflies in place?

[@AshRowland]

That's actually a great idea, yea, I'll definitely do that

[@AshRowland]

I didn't, but it is in my list of things to do before they go back on the bike, thanks for reminding me 👍

[@matmiller5256]

Nice methodical work @ AR/ hopefully no leaks when reinstated

[@AshRowland]

Fingers crossed!

[@andrewashman3333]

What a great video - really well filmed and so helpful, thanks.

[@AshRowland]

[@ste1872]

Great job m8 they look awesome 😎👍🏻

[@AshRowland]

Yea, they did, but I used the wrong kind of paint and got petrol on them so I'll have to do them again at some point 😔

[@coplandjason]

Very useful "how-to" you've made there Ash, good job. I've got this job to do at some point on my GPZ, it's been a while since I've played with a bike that had carbs but I grew up with carb engines with clockwork ignition, I'm just out of practice :-)

[@AshRowland]

It's quite therapeutic really

[@phillipparkinson7145]

Cracking job Mr Rowland😃

[@AshRowland]

Thanks mate

[@ianreid5789]

You made an excellent job of them carbs

[@AshRowland]

Thank you mate 👍

[@slewisedwards]

Quality use of a Premier Inn 😂 The carb icing thing was a huge overreaction. In COLD weather, like -5 degrees or more, after setting off the bike would occasionally just lean cut. Wait for a minute and you were off again. The solution was to allow it to warm up properly before setting off. It never got stuck at an open throttle or anything like that. The press got hold of it and said it could cause a rear wheel lockup and accident blah blah blah. I doubt if it ever did. The fuel was thought to be a factor too, but was very different back then. We ran them on four star leaded ! Modern unleaded ethanol infested stuff probably doesn't cause icing in the same circumstances. Also, what rider now would take on these out in -5 degrees 🤪👍

[@AshRowland]

That's a good point, I didn't even consider four star! Shame you can't get it any more

[@twin40dave]

Nice job ash they really do look brand new 😊

[@AshRowland]

Hopefully the rest of the bike will look this good when I'm finished

[@daleevans3841]

I'm not gunna be one of those guys who comments on every video but carb icing! This is miserable and I've had this on my air cooled Ducati - took me a whole summer to figure out what was going on. It would cut out after 15 mins then only start again after a 5 min wait (ice would melt), and cycle would start again. The solution? Avoid using cheap supermarket petrol! I now run everything (even the lawn-mower) on Shell V-Power and it's been fine ever since.

[@AshRowland]

I've kept the original upgraded water heating pipes attached hopefully to avoid the icing, thanks for the tip with the fuel, I only ever put the best in all my bikes 😃

[@kevinhaigh3962]

They are looking awesome fella well done definitely

[@AshRowland]

Thanks mate

[@ianhorabin9763]

Good job,I've built many carb sets,they look the Bizz..I normally set air fuels to 3 turns out as a base setting..👍

[@AshRowland]

👍

[@leon0]

That's really model dependent. Ash could get a gunsons colour tune to set then properly, with the engine warmed up. No O2 sensors or OBD2 connectors on bikes of this vintage.

[@Busaboy1300]

Awesome job ash.they do look brand new nice one mate.

Really nice job there Ash. Can you give a figure on what it cost to do this job ?

[@AshRowland]

Thanks! I reckon with the hose, clips, screws, carb cleaner and other materials probably about £100 ish, but I've got plenty left to do it about 5 more times! The rebuild kits were only about £10 each

[@SuffolkZX]

Great video thanks, going to strip my carbs soon, can you tell me what size o rings you needed?

Gotta ask why did you spray them ? As ive found any paint on carbs turns to a gooey mess when you introduce carb cleaner.

[@AshRowland]

To make them look nice... I'm not planning on spraying carb cleaner on the outside of them again

[@vlratcliffe1]

Wow id like this done to my cb750 carbs .where is best to have these done in cardiff area .

26 minutes of video is about 12 hours of work 🤣

[@sjk8273]

But you do appear to have a high level of expertise. This isn't happening just with the aid of a Haynes Manual, surely? What's your current best guess to get it completed?

[@Cullz.182]

Stripping, cleaning and rebuilding carbs is quiet easy. I'm like Ash I do my own and learnt from a haynes manual as long as your organised and label bits it's like lego. First time was daunting but I've done them on a kawasaki zx9r, triumph trident 900, suzuki sv650, honda vfr400, suzuki gs 650. With a haynes, youtube and elbow grease you can do most jobs in a bike at home or in a hotel room if you choose.

[@AshRowland]

I've been taking things apart for as long as I remember... My current best guess would hopefully be in time to catch the end of summer

[@AshRowland]

👍 👍 👍

[@leon0]

This is a journey, surely, not a race. If it was just about getting it on the road, you wouldn't be doing such a thorough job. You'd just fixing the major broken bits and chanting "rebuilding... rebuilding..." whilst covering everything with rattle can black like VGG. You, on the contrary, are doing the job with real care and system. It's great.
