Thor called in the big guns

As many of you know, Thor busted his bike last fall.  He has been putting it back together slowly hoping to race soon.  He finally has all the parts and is very close to getting it together.  However, he needed  a little extra help and had to hire a specialist.  One with tiny hands to get in all those hard to reach parts.  You know how expensive specialists can be, fortunately this one worked in the currency of chocolate chips.
