    Update:
    Got the cases together and jug/head on.
    Started work on pulling the major dents out. Found a guy to fill and paint it with house of kolors UK-4 over BC-09. Ive been cutting the heads off of bolts, tacking them on then threading on a slide hammer and its been working really well. Ive never done any body work beside some fiberglass so im pretty happy with the results. Ill be sandblasting and priming this week!

    Probably not as good as a pro, but i think this is fillable and much better than it was.

    You've improvised your own "poor man's stud puller". The real tool is less invasive, the thin pulling studs are press-welded so there's less heat warpage and less cleanup/metalfinishing afterwards. Considering what you're repairing and the cost of a stud welder/puller setup, your solution makes more sense...unless you have money to burn. Either way, the slide hammer is required. IOW, completely legit repair technique and the right way to deal with dents this deep. IMNSHO, the thinner you can make the filler, the better.

    Now, just take your time with the block sanding, allowing several days for the fillers to fully cure, outgas, & shrink before the next stage. It'll probably take 3-4 rounds of progressively finer fillers & block sanding to get the surfaces really straight. I like to give the last application of scratch filler at least a week (2 is better) before the final block sanding; that way, you'll be sanding material that is unlikely to shrink any further months, or even years, down the road. It's all in the prep, get that right and you have an excellent shot at a first rate paint job. Time, patience and perseverance are the novices best friends...and can compensate for a lack of experience. An extra week, or three, now can pay more than pay you back for years to come. Looks like you're off to a great start.

    X2...it's come a long way. Still some hammer & dolly work to be done, before what remains of the dents are shallow enough for filler. Fortunately, the metal appears to be solid and rust-free...giving you something to work with. (y)

The loctice product i used is probably way overpriced but i had access to it. The kickstand prices are rediculous so this was the best option and came out great.

    How many of you had Schwinn Stingrays as kids? My dad is a collector and growing up with them, ive gained a love and respect for the bikes.

    Nice job with the kickstand! Nice work on the lever tips as well. You just can't beat the price of "government work" :)

    Stingray kid with a grandfather who had a bike shop. Great memories of working with him at the store - he was the best

    I technically had a yellow 5 speed. My good friend who later gave me his old S65 younger brother had it. Their Mom backed over it bending the frame,I harvested the parts for another bike and cut up the frame. At the time they were used bikes......

    I saw from a previous forum post that Duplicolor BCP103 caliper paint was a good match and i happened to have some in my garage! Gave it a try before sandblasting to check the match and im really impressed. I can only speak to the paint match but i have high hopes since my G35 brake calipers still look great after 4 years. Highly reccomend this for cloud silver.

    I believe that there was a "Cotton picker" added to the lineup, in 1970.

    -3 speeds axels have no holes for cotter pins and are “crimp” style nuts, not castles
    -4 speed air cleaner doest have a tab for a rear brake cable. It also has a welded panel inside for the element. The red bike has the opposite of these things
    -this is a lot of work!

    Body guy is making great progress, the one pic below is amazing considering the dent that was on that side of the bike. Also trying to make a new carb look a bit less chinese. I dont know the girl unfortunately, a friend sent the pic!

    Looking good. Looks like you have plenty of carbs.


    Welcome to world to the world of subtle differences and ongoing changes. I have seen HK0's in the wild with both cotter pins and without (self locking nut). According to the parts manual I have, there was a change that occurred at serial number 143100. The cotter pin lock nut started at 143101. ....however, a lot can change, or be replaced over the course of 45 years and multiple owners.


    You are correct, the HK0 air filter housing should not have a tab for the rear brake cable. If you're a purest, it can easily be removed. Regarding the differences inside, I have seen housings without the frame, with a frame but no screen, and with a frame & screen. So many changes in this area that I have no idea what is 100% "era correct". Personally, I would remove the tab, paint and source a filter frame. The frames are readily available ...and cheap too.
