If your hoses are 10 years old or more....time to replace. OEM is expensive too.
They have shipped!

Yep formed hoses are expensive. OEM they were $25-50 per hose last time I bought them almost 10 years ago.

I just ordered a set of these in black.  The 23 year-old original hoses on my B4 were scary looking, it'll be good to have some new ones installed on the bike. 

Thanks TJS for bringing these hoses to my attention.

Well, pulled my old gsxr out to ride while I work on the Bandit; carbs were on the gsxr had other ideas! So, water hose install and other modifications will have to wait...eg 33mm FCRs...just waiting for the USA $ exchange rate with Japan Yen to get better. These things have been on my list for years!....Worst case rebuild current carbs with Viton gaskets and OEM emulsion tubes, tune, ...bla blah blah

This is the track bike and sometimes street bike I put the SAMCO silicone hoses on.

TJS, have you installed the silicon hoses on your B4?

I was back in the garage today, working through a laundry list of to-do items on my project B4.  One of my tasks was to replace the B4's old coolant hoses with the new silicon ones.

My mistake was assuming that I could install these new hoses with the OEM Suzuki hose clamps, just swapping the original clamps over to the new hoses.

Everything went great until I tried to put the spring clamps (Suzuki calls them "clips" in the parts diagram) back onto the hoses that run from the top of the cylinder head up to the thermostat housing.  I'm talking about the wide, black clamps you have to "pinch open" with pliers.

This was when I discovered the new silicon hoses are just a bit thicker than the OEM hoses.  I found that once I had the hose slipped down over the connector on the cylinder head it was impossible to squeeze those spring type clamps far enough to get them onto the new hoses.  I tried every way I could think of to get the clamp over the hose but nothing worked.

I was lucky, though, because I had some extra Suzuki hose clamps available in my extra parts box (from a replacement radiator + thermostat housing that I bought off Ebay).  In place of the now too small spring type clamps I substituted two of the clamps Suzuki puts on the other end of those hoses.  These are the regular screwdriver-tighten style clamps.

It was a tight fit down there in the spark plug valley of the camshaft cover because of the big metal bump of the clamp's tightening mechanism.  They just barely fit next to the Coil-on-Plug stick for cylinder #1 and #4.  Also, getting them snugged up on the hose was a bit awkward.

So in the end everything is good.  I filled up the coolant and ran the bike to warm it up and get the air out of the system.

I just didn't see that little bit of difficulty coming.

My track bike is still on the lift and waiting for Viton FCR gaskets, float seats, and float needles. So, Bandit hasn't had any attention. I did order the stainless hose clips with my hose kit. I have noticed they are thicker than OEM; I just rub some spit or water wetter on the inside to help the hose slide onto the water connections. You have to be careful not to rib the outside of the hose when installing anything other than Suzuki clamps or clamps designed for silicone hoses.
Please post a pic!

Okay, I understand now.  You have to be gentle with the silicon hoses.  (I've installed silicon hoses on turbocharged cars but they came as part of a complete kit so I didn't have to think about the clamps)

Thanks for the pointer on this issue.

A bit of internet research tells me I need to get some T-bolt style clamps for my silicone hoses.  I see that the difference is the silicone hose compatible clamps have smooth interiors (no worm-gear holes allowed!) and the better versions of the T-bolt clamps are even gently curved to further protect the hoses.

Maybe you can help me out a bit more by providing the correct sizes of clamps to buy.  I'll need two sizes, right?  Because the B4 cooling system uses two sizes of tubing; a larger size for the pipes that run to and from the radiator and a smaller size for the pipes that run from the cylinder head to the thermostat housing.

What brand of clamp are you using?  Web link?

This is the kit I ordered.

You can also get custom from Samco suppliers.

Got the same kit (in black) mounted on my B400 back in September this year (2016). Super nice.

The only cons is the hose clamp that is right between the spark plus prevent from using a regular spark removal key. So anytime you want to remove sparks #1 or #4, you have at least to remove the clamp. I hope it can handle the pressure so you don't have to empty the cooling circuit...
