Can anyone point me in the right direction to purchase valve stem oil seals for an 88 nc23
For less than £100. Really need to start building the head up!

my local dealer can order them..so I am sure yours can?

Or, if not, then get hold of Graeme France on here, or Rick Oliver or then og to shops online like David Silver spares.

And welcome!

If you're building the head then you'll also need the head and base gaskets. Then ghs small stuff like exhaust and can chain tensioner ... might be better to look for a top end or full gasket set.

Cheapest valve stem seals i can find are on CMSNL.com 8 euro's each which i think works out just a bit cheaper than david silvers, that is for the NC30 though.

We keep these in stock - genuine Honda:

Tried / failed with pattern stem seal parts ..... do it once do it properly.

Most other parts you may need in stock from oil to genuine Honda valves and even new valve grinding tools / fine paste / cylinder head stands to suit Honda 400s !!
