FWIW I do every single bit of work on my bikes, but I do NOT touch two stroke cranks and other press-fits. Crank builders have more equipment and skill than I have in this department. I will pay money to know I have a good bottom end.

++6 on that, I know what I can do and pressing a crank on any bike is so worth the cost of shipping it out, here in Oregon, we have RB, he is well respected in the 2 stroke world, so when my 2VO takes a shit I am going to buy an A1 crank from him.

Look at it this way you will spend about $200+ for the press and bits and when your crank is wrong and you ruin the whole engine you are out another $ 600+ JMHO

He saved me some serious money. I was ready to just go ahead and replace everything, but he convinced me that for a street ridden bike, my rods were plenty good for another 15-20K miles. What I thought would be a $500 crank rebuild turned into I think $225 bearing replacement and truing. I don't have his contact info handy, but his business name is Vintage Specialties. Crank work and boring are the only things I don't do myself on the RD. For what it costs to have an expert do it, I can't see why one wouldn't go that way.

Send it to Lyn. Excellent guy.
