1978 Suzuki DR370 Historic Class Hellride
« on: Jul 09, 2018, 15:04:21 »
I came back from Mid-O with a 1978 DR370.  It's a good running bike with a lot of painted rust, but the bones are all good. It'll need a bunch of work to make it pretty, but my intention is more to have a bike I can run in AHRMA Post Vintage MX Historic Class races, Hare Scrambles and other events.  Plus one that will handle itself on the trails I frequent many weekends. 

Here it is in it's current glory with a PE tank on it for now:



The bike came with a KE175 or something tank that was also rusted to shit.  SP370 and DR370 tanks aren't easy to find, so it'll be quite a challenge to find one.  I have a line on some dented tanks, which I intend to buy if the price is right.  Through a day of searching, I wasn't finding a comfortable match.  Then, after about 20 minutes of his own searching, Kanticoy pulls a horseshoe out of his ass and finds this tank:



It appears to be a desert tank that may just fit.  I was reluctant to drop the cash, but it's yellow and the shape is rad, so I will do what it takes to make it fit.  Here's a stock SP tank for reference.  The DR was the same, but yellow or silver:



Here's the bottom of the plastic tank vs the stock SP/DR tank:





By measurements, I think this may be a tank made just for this frame.

Onwards and upwards...

First things first...  The muffler is pretty bad rot, so I cut the inlet off and grafted it onto a vintage Supertrapp.

In it to win it. You know I love a good DR!
I get not knowing, but I can't for the life of me understand not trying. It's only metal it can be fixed. Man up and risk a mistake in exchange for a lesson.

Love those alloy rims with the little extra lip on the side, hope you're hanging on to them?

For sure.  The front rim is in great shape.  The rear rim is straight and appears dent free, but seems to have been painted with a silver paint.  The spokes are all rust, so when I take the wheels apart to replace them, I'll clean the rims up.
