it's a 210! those are pretty sweet! who had it? looks like they rigged an improved intake and SHA carb setup so that rules, fit a decent pipe on and you should be good. if the ignition is bad that's a dickpain but if it's ok then it'll probably stay that way - and it looks like it's got the updated good transistor too. win.
I vote hard for fix your jawa because jawas are cool and motorswapped jawas are meh
Wait just read all he other comments - you HAVE a good pipe? WTF man! don't ditch the pipe cuz it hits the pedals, modify the pedals to not hit the pipe!!!
any swap you swap will have more difficult issues than that anyway
