A couple of pics of my 73 Bultaco Pursang...I have never ridden this, but its been around for over 10 yrs now...I was working for a guy who gave it to me as a Christmas bonus..Pretty darn cool as far as bonus's go..My boss had bought it brand new...turned it into a flat tracker and raced it 2 times...2nd race it siezed...He took it back to the dealer and had it rebuilt... picked it up, put it int the garage..never rode it again...

I would someday like to put a 21" front rim/tire on it, get some knobbies, then take it and enter it in a Vintage MX...

 

Now that is a good looking one you have there i would get this one going for sure , i had a neibor who raced MX on one of these and he did pretty good when he was sober !.....

Im pretty sure this would run fairly easily. It has good spark and when i took off the expansion chamber. I could look into the bore with a flashlight...looked new to me...This will definitely run someday and I would really like to turn it into a MXer again..
