Original GS6

[rob w]

How about this one.
1977 Penton GS6 400 - guarantee 100% original to the day it was new - 241 Total miles.

Mike Winter - You tell me I should take some pictures before I start a project, here they are.
Has a horn, and compression release.
Haven't even wiped the dust off yet, looks like it'll need a rear fender, and....
But, not too shabby eh?

Nice! What carb? And is the compression release via extra plug hole or through a port in the back of the cyl? Looks like sidestand--any mounts for center? Whenever you get around to it more pics and closeups of pipe, etc would be great-- Congrats!

Very cool!  I had one just like it, sold it in 2003 on ebay to a guy from PA.  What a find, where did it come from?

-Had a bunch of orange Pentons, sold all except my 76 400 back in '03

John, OEM 38mm Bing carb - compression release is through horizonal  port provided in right side, rear of head.
Will take pics of whatever you want, and will look for center stand mounts today.
Kurt, I bought both this one and a 77 MC5 400 (see "clean machine" now on page 7) about 5 or 6 years ago. Both bikes were purchased new in 1989 from Flint Indian Sales - Flint, MI. This one has a 1991 Michigan ORV sticker on it.
Neither bike belongs to me today.
Cool is'nt it, should be a real fun project.

Cool beans!
So, was the supertrapp exhaust tip an optional item when they were new. All the GS-6 bikes I have seen pics of have the large enduro silencer. That rear pipe section looks more like an MX pipe. Mike

I enjoy rebuilding and appreciating Pentons!

Rob,

DC Plastics is in the process of duplicating the original Falk rear fender that I sent to them.  My guess is it should be available very soon.  I'll keep you advised.

I have the same bike except it is a 250, but it has 1500 miles on it.

Tony, Thanks for sending DC your part to repro. That's my closet option after NOS - which may take some time to find.

Mike, I've seen that same pipe set-up around these parts several times before. The only GS I've ever run across with the bazooka/enormous pipe, was a 125.
?
Always something new to discover......

Don't you just love that original patina of the front Marzocchi forks? It is a shame that there isn't any exact color paint to match it. I decided to leave the fork lowers on my 76 MC5 400 original, but since my shop isn't heated all of the time, they have begun to oxidize and I will have to paint or clear coat them anyway. I may have to resort to having some paint custom mixed to match the original. There have been a lot of "close matches" by POG members, but I don't think anything has ever been found to match exactly.
Did you see this NOS set of Ceriani forks that sold on eBay a while back with a somewhat similar finish? Mike

Nice bike Rob. I've got one just like it with minimum mileage (speedo missing when I bought it). I'm missing the horn but haven't really looked for one either. Mine has the MC exhaust tip and a Lectron carb. I added a decompressor. The bars were tweaked and the right side foot peg bent. I suspect the owner let this beast get away from him and he parked it for purposes of self preservation. It's a HOOT when I take it out to the club I belong to, the younger guys don't know what it is and the older guys just stand there with their mouths open remembering the good old days. I get the same response when I take my '72 Six Days (it's in great, original shape also).

 Very interesting,  I had a '78 KTM 400 MC5 that was also bought new from the same Flint Indian auction.  The MC5 was brand new, never had fuel in the tank.  I had it in my living room.  Never started it, sold it to a guy in Rhode Island in 2000
