More Wrenchin than Ridin
NO for 150 you'll need a 3.5" wide wheel. Unless you widened the swing arm it will rub it or the chain. I go here to check what fits:

You can get a 140 on the stock wheel but it rubs on both sides. A little grinding on the tire fixes that.
On the edge of the tread there is a ridge out from the sidewall of the tire, with the bike on the center stand and idleing in gear I ground this ridge back a bit, just enough so it didn't rub on the swing arm, ground out the chain gaurd too. Any bigger than that you need a different swing arm or a hardtail. You might need an offset front sprocket as well.

yeah im building my 81 special II. im puttin the tc hardtail kit on it. so i wont have a chainguard. i can widen the rear frame for it to fit if needed. just need to know if the 150 will mount onto the stock rim.
