Penton 400 questions

[tim bowers]

I'm close to firing-up my MC5 400 but I have
a couple questions that need answering first.
1) what is the best premix to use for these,
   and at what ratio? I have a new motor
   internally and would not want to "roach"
   it right off the bat.
2) Does anyone make a 520 chain and sprocket
   conversion kit for these. The teeth on
   the present sprockets seem wider than
   normal and I was told they are for a
   size 50 chain system.

Any help would be appreciated.
Thank you

I have a 77 175 that came with 520 chain and sprockets so I would imagine you should be able to find the same for the 400.  The rear hub is the same, but I don't know if the countershaft sprocket shaft would match up.  If I get a little time, I will pull my sprocket off and see if they are the same as the 530 sprockets.  Perkins or Buenher should have the parts.  
I run premium fuel and mix at 40:1.  Should work fine.

Thanks Rocket, what kind of oil do you
use? I recently have been told about a brand
called WP. It is about 28$ a gallon. I have never heard of it.

Go with Golden Spectro Concentrate at the 40:1 and you will be good to go.
