Hi From New owner of 76 DT400 ready for restoration #1
Just purchased a fairly good shape DT400 and planning to restore to stock as close as I can get. I am in need of lots of help and off course replacement parts.
The engine seems to run ok with some hesitation at RPMs above 4K.
Need to start with following:
Visible intake boot cracks, need a replacement and have not found one?
Reed valve stopper clearance is app 9.2 mm. I have a 77 DT250/400 and states it should be 7.5mm? not sure if this is true for 76 models. Should i re adjust (push it back with pliers)?
I am planning to put some adhesive on the boot for now to stop it from leaking , redo gaskets and start it up and adjust carb.
Need gasket for reed valve.
Need to re chrome the springs on the rear shocks. Any ideas?
The previous owner removed the airbox and installed a hi flow filter, not sure if i should keep it or go back to original filter airbox? i have the original airbox. Would the carb need to be adjusted with the intended filter?

I will be back for a lot more questions however any help regarding the above questions, and sourcing parts for the above bike and any other info would be greatly appreciated.

Thank you Enduro fans.
Jason

Hi From New owner of 76 DT400 ready for restoration #4
Welcome!

76 has a different reed valve assembly... I wouldn't mess with bending anything.

If you want to go to "as close to stock as possible", you'll want to install the original air box. Most people run the stock air box unless they don't have it... much better protection and you don't have to worry so much about sucking water into the engine when it's raining or when washing the bike.

Manifold can be found here: www.dcvmx.com/xcart/product.php?productid=183100&cat=650&page=1

Search ebay for "363-13621" and you'll find several options for the reed gasket... fits several models including some snowmobiles. (363-13621 is the first two sections of the gasket part number... you could put in the whole number but some sellers don't use the whole number... first part, the model code... and second part, the type of part... are generally the most important)

Welcome! to the site! Lots of DT400's here and lots of good threads on restoration/Modification.

IF it isn't one thing, it's another.

Hi From New owner of 76 DT400 ready for restoration #6
Thanks for the help guys. I will start posting photos I need to reduce the size so the site will accept.
I am going through the site here to absorb as much and start planning the project. The engine , tranny are in good shape, no need to remove however i really like to touch up the frame. But first I am going to remove fenders, tank and lights/assemblies for paint. I really like the paint scheme DEETS had posted on Paint Thread on his DT400 which is Yellow with White (instead of silver). To get started , here some of my questions:

How to remove/replace the glass oil site on the oil tank?
what paints/numbers should I use for white/yellow combination same as DEETS DT400?
I have a small dent on the tank, can it be just bondo ed or should be straightened first? Should i get a body shop to do the repair? I am not very well versed on body repair (don't have patience) anyone in this site offering complete paint job for the tank, fenders, light fixtures? (Yellow and white combo)
How do I remove rust on my chrome springs? anyone offering re-chrome? is there a chemical that removes the rust?
what is the best paint to use for the frame and engine case (touchup) should i avoid touch up and do complete primer and paint?
How best to remove pitting from rear wheel center/ brake housing?

Thanks again everyone
Jason

Hi From New owner of 76 DT400 ready for restoration #8
Find wood deck cleaner that contains Oxalic Acid. It will remove rust from chrome without any rubbing or scrubbing. Works amazing. I've used Behr brand from Home Depot. Soak a couple minutes at a time and rinse. Don't overdo it. It can be diluted a little with water too.. Not a substitute for re-chrome or a concours restoration but works pretty good. Chrome plating is not as easy to find these days... best to search Google for a shop and contact them.

Paint is not cheap if you have it done... one of the best is Tim Rains in Oklahoma. www.facebook.com/2-Brothers-142174245972773/ Marbles Motors also might be able to help.

Your photos appear to be small enough files... not sure how you're attaching? Click on the attachments button below the create new message box and then either search and attach with the add files button or drag and drop into the box. Then you can insert photos into post as well.
