Greetings,

I came across an ebay ad for Clarke aftermarket plastic fuel tanks and noticed that they have tanks for 75 to 77 MC5's.  In looking at the tank it the shape and size looks a lot like the old Hi-Point alloy tanks.  Does anyone know how / if one of these would fit on a 72 Six Day?  I would like to find something I don't need to drain after every ride.

Thanks,

KD

Those Clarke tanks only fit the MC5 frame to the best of my knowledge.  Windsor made one that fit the Highbreathers in the enduro watermelon style.

Thanks Larry.

Kevin,  I have one if you want to try and make it fit.

Larry is correct, that Clarke tank only fits the MC5.

Too much of a good thing? I think NOT!

I have been running an orange Clarke "Toaster" tank on my frame breather "76" GS 400 for about 2 years now and it fits fantastic.  Have Clarke send underside photos of both tanks they offer and if the same, it will work OK.;)  So far, awesome performance from their products!

Kip,

The Clarke Toaster and MC5 tank are for sure different as the toaster was designed for the big backbone of the GS and the MC one for the smaller triangle build of the MC5.

Thanks Kip,

I'll see if I can get Clarke to send me some photos with the dimensions of the tunnel on the tank.

I want to preserve my original tank for a 1977 Penton 250 GS6 and have been thinking about using a Clarke Tank and have been wondering if the tank below would fit. I will be racing this bike this season.

John are you looking for a large tank,or a small tank for your GS6? I have a couple of extra large tanks. Give me a call 217 260 0237  Later Gary

Clark makes a GS-6 tanks. Dave McCullough has one on one of his bikes. Mike

Yes, Mike Winter is correct. I wanted to preserve the original fiberglass tanks and installed the Clarke gas tanks on both of the 77 250GS6 bikes that my brother and I rode in the ISDT RR. I coated the inside with Caswells sealant on both before putting any fuel in them so the decals wouldn't peel off. The petcocks and petcock grommets can be purchased from Wicks Aircraft Supply for a very reasonable price. So far they have worked great.Hope this helps.

Dave,

Did you use the tank that in the link that I posted?

John Hubbard

Oops !! Sorry but I made a mistake in my previous post. I did install plastic tanks on the 77 GS6's but they were Windsor tanks and not Clarke. I recently bought and used a Clarke tank on my 82 Yamaha IT175 and must have had "Clarke on the brain" when typing that in. I bought the Windsor tanks from Al Buehner quite awhile back and don't think he has anymore of them but you might check with him to be sure. Sorry for the incorrect post.
Dave McCullough

Thank you Dave!...That would've been a 220.00 mistake had I bought the Clarke Tank.  I'm going to Gary Ellis's advise and just treat the tank with POR-15, and call it a day.  Thanks for your help gentlemen.

John Hubbard

Dave,  I have always wondered if the Caswell coating would withstand the flex you get with a plastic tank.  Apparently it is not brittle.  Have you checked for cracking?
Thanks
Mike Lenz

Mike,
I haven't looked at it recently. I'll take a good look inside the tank next time I'm at the storage unit and will make a post on what I see.
