RD400E Special
« on: March 19, 2019, 07:01:41 PM »
As a young man, I lusted after my friend's buddy's RD400, so after collecting parts that have laid semi-dormant for too many years (had a hard time finding a motor) I ponied up and bought one! Already fairly modified, with a GSXR front end, some long expansion chambers, but was stoked he'd forgotten to mention larger carbs being fitted!
Even though I like its bare metal tank, I miss the wider, taller UK tank, and wanted to put make it my own, so
here's how I picked her up:

Testing out the shortened, stepped seat! Mocking up a bracket I fab'd for a Lucas tail light  and a Harley bobber front fender:

Very cool! '78 is my favorite of the 400's even though I have a 76, 77, and a roach  '79 Daytona that is in major need of restoring and getting back together one day...

Looks like a matching rear wheel will be a challenge to fit in your stock arm.
The front looks good though

I do have a 3.5" gs500 wheel I may try and fit, altho the 3 spokes put me off!  I may change to a Daytona rear, get a little more rubber on the road, lighter too! :umm:

I rattle canned the Euro tank, going for 20ft looks, drying as we speak :)

Twists of fate are surely odd! Decided to take a break from swearing at my Vdub, and organise shed space. An ideal time to check out paint match (spoiler: it's not) on the impromptu rattle can'd Euro tank.
But just for fun, I thought I'd try on a gs450 tank. Now, as my seat was shortened in length by the previous owner, its closer to the tank, but with said Suzuki tank, I can use standard mounts, hinges and even the lock!
It may be a tad sacrilegious to consider an alternative tank, but I'll take some photos, see what u y'all think :)

The GS tank certainly has a kind of Dunstall look to it, but it'll need the petcock relocating. The decal not matching the same angle line in the tank's knee indents is bothering me, so I may go for option 2, Goldilocks style :eek:

Good news, my new landlord is into bikes, already smack talking my RD400, waging his Kawasaki 500 triple can out drag the RD. I pointed out mine's souped up, but still...
Amazingly,I just tracked down some Spec 2 pipes for 240..She's already lighter than stock, and I still may fit the Daytona wheel..
On the 1/4, it's
looking like stock Kwak does 13.5
Breathed on RD like mine 12.9....
and he weighs 20 lbs more :)

Either way, it's just the kick in the rear I need to get motivated :)
