Jeeze
I have 1 complete CT1 and 1 complete CT2 and enough parts to make 2 CT3's.
Also, I still have the CT3 I brought the day before my 17th birthday in 1977 but now raced as a AT1.
Where do I find a sucker like the one that paid $7k for this one.
Hot up parts were from a variety of US companies. The best hot up tips was published in Trail and Track! Piston and port mods, pipe and carby stuff.
Original Yamaha gear sets and internals can be changed with lots of success (MX125 go straight in). There were at least 5 different heads that you could buy for them and they are all getting rare (dear in price)!
They were bullet proof once you got the ignition sorted. Here is one reasonably simple mod site!
