Slow air cutoff

Post by filupsd » Thu Dec 28, 2017 12:08 pm



Stupid question time. What is the function of the slow air valve on the carbs? Had them rebuilt a few years ago and very sure he didn’t do the valve. Thanks

Just me but I would stay away from SaberCycle. They don't have a very good reputation.

SaberCycle is a one way street, all their way.

IF, anything is wrong with what you received, it is ENTIRELY YOUR FAULT,

that witch once actually joined up on the Saunders forum and tried to discuss her business practices with us..... the more she talked, the worse it got.

The very first post puts it like it is, read it very carefully, it includes an email back from the lady, and she said it right there, "she don't care".



your money, but my advice, do NOT call or contact that witch.

One thing that I do, is monitor for Good Threads, on any forum, I am not partial, I bookmark them all.
just thought I would go look at what this subject brought up, and I have a bookmark folder on SabreCycle:


SABRE CYCLE stay away!

I have deleted my slow air cut off valve. It was to make the carbs easier to take on and off, and fix potential (and perhaps real) vacuum leaks.

All you need to do is to remove the valve and block the passages, and make or have made block off parts for the intake horns.

My bike runs fine, no backfire, no increase or decrease in mileage, no changes in sync or idle.

I have the dimensions needed to make the block-offs, pretty simple to do on a lathe

I've taken the secondary air system off of both of my 1200's. It sure does make removing the carbs a lot easier!


With all the good-bad information about Sabre Cycle on the internet, I am surprised that people still buy from them.
