I am in the middle of restoring a 1977 rd400 2 stroke twin, I need some input on paint. I sandblasted the frame and decided to powder coat the frame instead of regular automotive paint and clear coat, as powder coating is more durable. rest of bike will be paint and clear coat. i chose the "bike black" color with the mirror finish. Now i know in 1977 they didn't make a mirror finish in coating, but as I found out powder coating has come a long way since then. i know it will be hard to see in the pics i took, but i was wondering if its not too much of a shine. like i said its almost like looking into a mirror with a black background. again hard to tell in the pics. rest of bike will be factory colors, in this case "chappy red" which will be done this week, will post pics when i get them. When I picked the frame up i found out they put 2 coats on, its nice and thick but now you cannot read the id # on the steering head, plus the sticker from the factory on the steering head didn't make it thru the baking process. stickers were used back then as opposed to the plates they use today. anyway look at the pics and let me know what you think. I will include some other pics as i started taking pics about half way thru the tear down.as for the motor here are my plans. cylinders were on the original bore, had some blow by on the old pistons so I bought some new wiesco's and sent them for boring. porting and polishing intake and exhaust ports, but not to the point of needing to run racing fuel, but will need to replace main jets. would love to find some bassani expansion chambers, but looks like i may have to settle for DG as they seem to be the only ones you can get new. the final mod will be to add boyesen power rad's. with all that i'm gonna start i figure I will need to go up at least 3 sizes on main, but won't know for sure till its done and I'm tuning it. If i am forgetting anything let me know or if you want to give additional suggestions it would be appreciated. oh and the yz 490 pic is there just in case anyone wants it. its going to have a for sale sign on her this spring. its really clean and still on the original bore, been ridden 3 seasons total. kicker spring is new but came off so that needs fixxed. hard starting now, but haven't looked into why, but once its going you better be hanging on........
