Default Re: Shifting advice

Unsynchronized gearboxes are a little more complicated to shift due to the necessary rpm matching needed. Usually just double clutching works for up shift since rpm needed for the upshift is lower than for downshift. The double clutch allows time for the input and cluster to slow down enough for a seamless shift. If oil level is low then it won't slow as fast. Keep in mind that is doesn't need to slow a lot to catch the next gear on a low rpm engine. Downshifting requires an increase in throttle position to match rpm for the gear speed needed for a relatively seamless shift from high down to 2nd. From second to 1st needs more rpm so most folks just avoid downshifting to 1st.
