Synch 25 4 stroke nisson carbs and H510 vac port adapter.

[210bert]

I have a carburated 25 hp nisson 4 stroke 3 cyl. and need to rebuild the carbs which is not a problem but after that I need to synch the carbs and need 3 adapters that will screw into 3 H510 holes in the intake so I can hook up vacuum lines and use a 3 tube homemade plastic tube manometer. Where can I find 3 and what are the size. Thanks for any info Ya'll.

Those ports are 5mm. The bolt that closes them off is 10mm in length, hence the 5-10 designation. Motion Pro has the adapters you need. You can buy the the stubby version (with vacuum cap) 1 at a time for about $5, or a set of 4 longer ones (without cap) for about $10. See the accessories at the bottom of the page at http://www.motionpro.com/motorcycle/partno/08-0411/
