Hi there, allow me to bring this thread back up from the dead. I've been trying to compile a complete list of dowel pins needed for a K5 and so far nothing I find is lining up with what Hondaman has said. I have found this website which has diagrams (search for "pin"), but what I have found that I have needed is this.

https://www.hondaparts-direct.com/oempartfinder?aribrand=HOM&arian=motorcycle#

Cylinder -- 12116-300-000 8x14mm (quantity 8)
Crankcase -- 94301-10160 10x16mm (quantity 2)
Head, Alternator, and Clutch Cover -- 94301-08140 8x14mm (quantity 9)

But if they are different variations of a 12mm, where is that list?

Thanks!

Cmsnl.com has charts that will show you what's needed and where. With the part number order where easiest to order.
Important to not use too long.
I have seen lenght of 22mm that can be too long not letting cylinder to mate case.

I ordered extra since they are not expensive and will easily be bent. Lenghts of 15, 18 and 22mm, different years different lenghts. The 8pcs for cyl- head (special something 14 mm long) need rubber gaskets around usually supplied by complete gasket kits (these 8 with gaskets not used with MLS head gasket). Important to measure that they will not bottom out and not let head gasket to compress and seal.
I have grinded some a little bit shorter to fit.

Also order the 8mm dowels for cam holders and various covers.
You need 12 or more if order all new.

If you have plans to remove oil pump, buy rhose 3 dowels too. They are easy to damage. I got 6 of them sent to me yesterday. Good to have.

You can also look it up by exact 750 model (K1-K6) at South Sound Honda/Services/Parts.
They varied a little in the 750 over the years. These guys have the best prices I have seen, but their shipping is just as high as all of them.
See SOHC4shop@gmail.com for info about the gadgets I make for these bikes.
