10 Gallon tank on rightful owners bike

[Chuck35]

Thanks Wingshot. DT30 has my pics and measurements and he may well have the donor tank from ebay by now.

Are there any considerations for these with IBA rallies and such? Do they need to be foam filled or anything?

IBA rides weren't the inspiration for this purchase for me, but it may happen..

I just wanted to be able to commute all week without a fuel stop.

New IBA rules are opening up a whole new can of worms on this tank because they won't allow the hump on back.yes ,tank arrived yesterday,I will open the box at the shop today and see what it looks like.

Is there any chance we can keep in compliance?

If anyone here is connected to IBA, perhaps they could take a look at the posts and pics of your work "subtle hint"

 

[dcarver]

IBA tends to be very conservative, IMHO.

However, rest assured that this tank is fully Candy Butt Association

...and should last you about 2.375 CBA riding years!

 

[Chuck35]

Are all IBA rides subject to inspection?

Could one complete a solo SS100 and / or a BB1500 using any fuel tank they wished?

Really? Why on earth would they do that? I mean, I could understand if it posed a safety risk, like that square edged coffin looking affair I've seen protruding out of the top of one guy's bike, but these tanks are nicely rounded and sculpted. These tanks look like they could have been stock if one didn't know better. I'd even go so far as to say that these look considerably safer than the traditional remote auxiliary tanks, which are often square shaped and sharp cornered, sitting right behind the rider, not to mention the various potentially leaky added fuel line plumbing and pumps that are used.

I don't see how anyone would ever know what equipment you have since all you do is get mileage witnesses at each end. The witnesses don't have to know anything about the IBA rules. I think it would only be at IBA type rallies that the rules would be enforceable. If you don't rally, then it should be of no consequence to you.

Maybe warchild can enlighten us to the changes coming down the road since he is the tech inspector for IBA

I agree......because an internet search probably wouldn't net you anything.

Done, that already. Results come back about aux cells, not modified OEM tanks. The IB Rally page only talks about the aux tanks. Again, hopefully Warchild or Iggy can enlighten. I know the rules only apply to the rally, but we already know one person on here who has made a modified OEM tank so they don't have to use an aux tank in the rally.

 

[Chuck35]

I had same results searching, also spent an hour or two reading neat stuff

Since this thread was started for a tank that is being built specifically for someone to use in the IB Rally this year. It would be good to know if the rules have changed. There may be others that are considering the modified OEM tank verses using a aux tank. I k now if I were to attempt to get in the rally and was successful, I would be doing it 2up and I don't want to use a tail dragger and have a whole bunch of added weight at the back of the bike when I could use a modified OEM tank and keep the added wieght more centralized. Especially with all of the broken subframes that we have seen over the years with guys that use aux tanks.

The only thing I can find on modified OEM tanks is in Appendix A section II #1 starting near the bottom of page 20 Iron Butt Rally Rules, Tips and Information dated 11/14/09 (It is copyrighted material, so you need to use the link)

In summary, they allowed it in 2009 but I can't find anything that has changed it since then.

When I built the 10 gallon tank for Riding Guy, he was sure according to the IBA higher ups that the stock rear angle had to be used. I questioned this ,as I read and reread the same rules section on OEM tanks that you have,and all I could come up with was it needed to be constructed in a manner similar to a stock tank. He still told me it could not have the hump. I think we need someone that is close to IBA techs to get a ruling on this.I can do this if this is what you want.

 

[Chuck35]

I've a PM off to Warchild asking for clarification. I'm thinking the hump may be uncomfortable when leaning forward, at least for an old fat fuc like me.

I don't think there's any restrictions on individual rides like the SS1000. You still have to stop x number of miles and get a receipt though I think. It's more the IBR tht this comes into play with. They've always had a maximum amount of fuel you could carry which this would have been in compliance with, but I don't know about these new rules.

 

[dcarver]

Watching...

Correct. The OP is building a tank for a person who is in the IBR this year.

 

[gixxerjasen]

Indeed, I was simply trying to address Chuck35's questions about individual rides.

Dang, is it time for the IBR yet?

 

[RidingGuy]

I just saw this thread linked from another thread and had to say - "hey! that's MY bike..."

DT did a fantastic job on this and it works well with the handlebars, risers, and tank bag I have chosen. We made some modifications to his original design to ensure it would comply with a NEW requirement for the Iron Butt Rally that all modified stock tanks maintain the same rise angle from the seat as OEM. DT's original design has a hump in the back that does not meet that specification.

For historical purposes, I HAD a modified stock tank with just a 2" plug in it that brought the capacity up to 8 gal and I ran it in the 2011 IBR. The extra 80 -100 miles range made a huge difference, as did the lack of additional plumbing, being able to use my stock fuel guage, not losing my rear seat for storage, and just loading the bike where it is designed to be. A local welder put it together for $300, and I had to seal it after the welding was done.

But it was ugly - and more importantly, only 8 gallons.

So, when I got my new rally bike I decided to get a real pro to build me a larger, more attractive main tank. DT's version was indeed much more expensive - but this is a one-off custom to my specs. Well worth it, IMHO. It's not for everybody, but it works great for me.

As for how the bike handles with the extra weight (6.8 lbs/gal), it does well because that is where the fuel is designed to go. I added a fork brace to deal with the additional flex (I still ride the bike like a sport tourer) and I'm happy with the results.

I'm sure there will be some "beauty shots" soon. I do work with some folks who do that. For now, I can't even figure out how to add my own pics - but if you are interested, shoot me a PM. I will be in Jacksonville/Daytona Beach next month as well as the MSTA STAR 13, Vintage Motorcycle Days, and a few other events in addition to the IBR, so feel free to say Hi.

Also, anyone who wants my 8 gal - it is for sale for $200 plus shipping. It needs re-sealed, but that's after 70K miles in 2 years riding, so a little work and you can have a long distance tank and save your stocker for when you sell.

 

[Chuck35]

RidingGuy,

Did you have any issues (wobbles etc) appear with the larger tank that led you to add a fork brace?

 

[RidingGuy]

RidingGuy,Did you have any issues (wobbles etc) appear with the larger tank that led you to add a fork brace?

no wobbles at all - but the heavier weight causes more flex on aggressive turn-in that is noticable enough to justify the installation.

of course, in OEM condition with touring weight, the forks need the stiffness, IMHO.
