Wanted 1977 400 Motor for MC5

[dwighthouse]

I currently have a 1977 MC5 400 (550 06587) but it came with a 1974 and a half 400 motor(4-5500874)Clock reads 7 of 74. What I would like to do is get the right motor for this frame. The reason being is that the case on my current motor is a little different. It dose not have the hump on the shifter side for the stabilizer. I would also be interested in having the right frame for my current motor. Any help would be greatly appreciated.

400 engines are difficult to find and the parts for them are getting more difficult to find as well. Are you certain that your bike was originally a 400? The frame number is the same for a 250, which is much more plentiful. Chicago Jerry is the engine rebuild guru go to guy for 400's especially. Mike

Thanks Tom. I will be dropping a check in the mail Wednesday. It's a perfect 77 MC5. I'll take a look at the motor when my son and I come get the bike. 12 hour drive from here. He's going to hate me for this.

I was looking at purchasing a 400 from this guy a couple months ago, he didn't seem in any hurry to sell it so I would imagine he still has it, needs complete rebuild and i believe he wanted about $200

Dwight how did you make out on that motor.

I ended up buying a 77 MC5 400 from Tom Brosius. I have to say that the bike is everything and more that he told me. Road it at the AVDRA event in Tucson AZ after Tom Height (I know I'm spelling his last name wrong) drove it down from Denver. It's almost to pretty to ride but have I an extra tank and plastic to use. I now have a pattern to copy over to my existing 400.
I can't thank everyone to much for all the help in making this happen.
