    Like ruwfo said that rear loop is not right, even the diameter is wrong. Probably so they could put it in the original frame. I would remove it all and start with a known rear section. Got a veiw of this from the rear? Even the shock mounts look suspect. Chris

    Thanks Chris!

    Thing is, sourcing the correct rear loop could take years... I get that it's not original, but I really just want a rider for some local vintage MX racing. I'll cut the vertical tabs off, weld on some barrels, slap on some paint and off we go!

    I really do think the shock mounts are OEM, but see what you think, below:

    Can you take a closer picture of the shock mounts? Can't really see the welds in the above picture but look like the mounts are in the original location on the swing arm. Although it only takes about 1" difference to make a big change in the suspension travel.

    Yeap, cut off the old stuff & make your seat you got work :thumbsup:

    How's the weather ?, SNOW i'm betting, it's coming my way, 10F for a high Sat, here in NW NJ :eek:

    Those look like, stock rear shock mounts, same as my 80 390CR. And those are way too skinny 35mm forks, and shocks are cheapy -Progressive's, sort of junk.

    Some up grades you can do, is 81-83 40mm forks, & same years rear shocks, make a huge difference. 15-1/2 shock length stock on WR

    So I would also need the triple clamps for the 40mm forks, right? I'll keep a look out for those. Those are Progressives and the shafts are pretty rusty, totally roached. When I rise up off of the seat they bang at max extension, so the bumpers are gone too. (my wife's gonna kill me! :eek: )

    Thanks John.

    Yes ,complete 40mm fork set with triple clamps, will bolt right on. Those 35mm are way too long, MX action, bent them back in the day on the magazine test. After i read that, i went with 40mm, not that i'm anywhere near as good as their test riders. Always felt like a chopper, with the stock length shocks, so i went with a slightly longer, for a more level feel

    That's exactly how I refer to this bike's current stance... "looks like a chopper". That's why I was sure that the 15" shocks were too short. Now I know better... We'll I'll keep an eye out for a 40mm front end, but since that will likely take a while, I can at least lower the triple clamps a bit, right?

    Is eBay my only choice for both the front end and longer rear shocks?

    Are you buried in snow?!
    Thanks John!

    unfortunately that maybe your only choice

    be careful on shock lengths, i'm 6' 2" so i can use all the height i can use.

    NOT as much snow as forecasted -only 3"

    So the '78 frame is how close to the '80?

    78 has metal airbox, vs 80 plastic, 78 seat with lower mounting stud

    But i'm pretty sure the motor mounts are different, so that maybe a bigger can of worms & in my opinion NOT worth it

    If your looking for a frame stay away from any that have a "u" shaped plate, like in this picture,
    as that's how the 75-78 mount the seat in the front
