How To Vinyl Stripe Installation on a Motorcycle Tank - Honda CB750 K0 Stripe Decal Guide | Part 32

How To Vinyl Stripe Installation on a Motorcycle Tank - Honda CB750 K0 Stripe Decal Guide | Part 32
Here’s what I used:
CB750 K0 Fuel tank stripes decals - ebay.us/RgrGQq
Monofil Adhesion Aid - ebay.us/YEvejR
Kapci 2k Fast Dry Primer Grey with Hardener - ebay.us/jkrUlT
Kapci 3k Clear Coat with hardener and thinners - ebay.us/qY5KoZ
Fast 2k Thinners - ebay.us/QTN5ym
Sealey Gold Series 1.4mm Spray Gun - ebay.us/GBnENE
Pressure regulator & Water trap kit - ebay.us/NuqRQU
Painting overalls - ebay.us/6wOdU5
3m Respirator - ebay.us/dVowSb
Sealey .8mm patching gun - ebay.us/76xTBF
Whenever I am playing around with one of my projects, I always try to wear good overalls like these ebay.us/2LOCDG and gloves ebay.us/gcA4XD
In this video, I use some vinyl stickers to put the side stripes on my CB750 K0.
I had already primed, base coated and clear coated the tank. I wasn’t 100% certain of the colour or shape of the stripes on the tank, so I researched online. The best option seemed to be to use vinyl cut decals, although sometimes they are painted on.
There are some guides to the size and shape of the stripes for specific years, but it looks like nearly every bike has something very similar with only the position of the pinstripes and the colours being different.
Before putting the stripes on I wet sanded the whole tank with 1500 grade wet and dry. This also gave me the opportunity to improve a couple of blemishes in the original clear coat :)
I found putting the decals on a little tricky, but using soapy water to enable me to move them around first really helps. I also used a hairdryer to heat the parts of the decal that went over the more complex curves at the front of the tank to make it more flexible.
Before spraying the clear coat over the stickers, I used, Monofil Adhesion Aid, adhesion promoter to give it a better key. This needed to be a very light couple of coats just to mist the decal and surround.
The clear coat was put on with the Sealey patching gun, and a good number of coats were put over the whole tank, leaving a reasonable flash off time in between.
The finished result is very good, I would certainly do the same job again using the same types of decals.

Looks fantastic!! I had a 1974 CB750 with orange metalflake back in the day. Beautiful bike. Nothing like a 750 4. I just acquired a 1998 CB750 and it runs great. It isn't pretty but a great project bike, so I don't feel hesitant to make it into a cafe racer style. Trimming off the frame behind the seat and welding on a loop to fit under the cafe seat. Your videos are great. Thanks for posting them. Hello from "across the pond" in Florida!

[@SPANNERRASH]

Cheers for the kind words, appreciate that! :) Sounds like you're at the start of an exciting project of your own. I'm definitely considering going custom with the CB750 I'm currently working on too. Happy wrenching!

[@1234567marks]

Thanks very much for that top tip re using soapy water to slide the decals during application, turns a nightmare into a doddle!, just done the tank stripes on my GT250A tank, worked a treat, thanks again 👍👍👍

[@SPANNERRASH]

Glad it helped you, Mark! It really is a great way of doing it.

[@dallaspolyak8894]

thanks for the reply

[@SPANNERRASH]

It's my pleasure

[@daveco1270]

Looks good. That kind of thing can be so nerve-racking. I put some non-stock vintage style Honda winged emblem decals on mine and I measured like 20 time from 10 different angles before sticking them on. Then I had to order another set because after a couple days I realized I didn't like where I had put them. Second time worked great, although every so often I see them and think they're still a smidge too low, maybe I should get another pair and try one more time.

[@SPANNERRASH]

Cheers Dave! Yeah it's really challenging no matter how you approach it. Sometimes I think doing it yourself makes the flaws stand out more to you too. :D

[@NomHeads]

Great tips, just what i was looking for! Thank you 🙏

[@SPANNERRASH]

Cheers mate, hope it helps! :)

[@smoothsam7]

Nice job

[@SPANNERRASH]

Thank you! Cheers!

[@miles-thesleeper-monroe8466]

Just found your channel and subbed and binge watching! Some fantastic tips but most of all no nonsense get a good job done real inspiration to have a go. I've done bikes with aerosols and 2k aerosols and had some fantastic results. Good work!

[@SPANNERRASH]

Awesome, thanks mate! Absolutely, you can be surprised what you can do if you just get stuck in and give it a go.

[@miles-thesleeper-monroe8466]

@@SPANNERRASH yes that's so true many channels try to be too perfect which puts people off. But the thing with you guys is that you know exactly what you're doing from a sound technical base, that's so obvious, really helpful vids for the enthusiast 👍

[@dallaspolyak8894]

how do you remove tank badges? Post a video on that, thanks

[@SPANNERRASH]

Hi, it isn't in the plans for the moment. But there are 4 main ways with badges. On an older style tank like the one in this video there are usualy screws, sometimes these can be rusted up. There are also badges that have plastic pegs that fit into holes with an interference fit, these need to be pried out carefully. Sometimes they have a round metal clip onto the plastic pegs to hold them on, side panels frequently have these. Some just have double sided tape, these respond well to a little heating to loosen the adhesive. Finally there are straight decals, sometimes under a clear coat. I hope this helps. Take care.

[@keithmon1234]

Great video...picked up some tips along the way. I see you used an adhesion promoter before clear coat...as you said any video I've seen they mist a clear coat on first so theres no reaction I've just fitted the decals ready for clear..did you have any issues with the adhesion promoter ? Have you clear coated over decals before with the misting method ? Comparing both methods would you say your method is better ?

[@SPANNERRASH]

You could watch our videos on the Fireblade stickers as well. I was advised about using the adhesion promoter by a very experienced painter from my local paint shop. The first time I used it I put it on a little too much and got a couple of runs on the surrounding paint, but I haven't had any problems using it since. I also go with a reasonably light coat over decals for the first clear coat. The idea with the adhesion promoter is that it makes the plastic surface a little softer so that the paint adheres better. I have also seen people scuffing the surface of the decals with a light wet sand to give the same effect. I suspect with a little care all of the methods will be fine. I think that with painting it isn't quite the science we would like it to be, and when you have a method that works for you, you keep going with it. It is more about experience and confidence than anything else. When I run out of adhesion promoter (which might be some time :), I think I will go to the light wet sand method, I don't think I would just spray onto unprepared decals, but I suspect it would work fine with an initial light coat. Sorry if this isn't that helpful, good luck with your project.

where did you buy the stripe from

[@SPANNERRASH]

Hi, I bought them from a supplier on eBay. Here is a link ebay.us/RgrGQq Good luck.

[@CB750K]

Since yours was a brand new gap with a new seal, did you experience any vapor-lock when getting to half a tank? I changed my seal on an old cap, and that happened to me. My vent appears to work... Just wondering if it's only me. First time to have a new seal myself.

[@SPANNERRASH]

I have had issues with the vents in the caps blocking and causing poor fueling due to the vacuum. Not really sure why it happens, but I have had it wth both and new aftermarket cap, and with putting a new seal in to an old cap. It's really annoying until you work out what is going on.

[@CB750K]

3 months later, but I found the problem. When I replaced the cap gasket, I'd also rebuilt the carburetor, and replaced the fuel lines. The hose was too large to go through the holes in the carb. mounting plate, so I ended up routing the hose wrong so that it went downward -- so the fuel had to go down from the tank, then back up to the carbs. After replacing the fuel line with correct diameter hose, no more fuel starvation. My fault, not the gasket.

[@puccetto70]

No mate, k0 don't need the stripes, but line by paint

[@SPANNERRASH]

That's very true, K0 did have them painted. But my hand is definitely not steady enough for that so opted for the next best thing. :) Very pleased with the result in the end from an aesthetic standpoint at least.
