Hello I bought a dt125 and plan on rebuilding this winter.  I've been riding the past few days and have been looking at parts.   Here's my question, i found a complete top end kit for the dt125 in the year 1978 including piston, rings, gaskets, cylinder jug, and needle bearings.  The only differences ive found between my 75 and the 78 model is the cylinder head has 6 bolt holes instead of 4 like on my bike.  What's stopping me from buying the kit for the 78 and buying a used cylinder head that would fit the kit.  Is there any other problems I might find? Don't want to buy the kit for 78 if there will be any other incompatibilities.

Reposting the same thing in different threads just gets confusing. ESPECIALLY as i answerd this question on Wednesday.
