Dragracing has nothing to do with low end.

humm

so the gain is?

Here is the deal. The advance weights can break off from the high rpms that drag bike's turn, so the old school way was to weld them at the full advance to keep everything in one piece. The downside is that a self start bike will kick back when you start it at full advance. With today's racing electronics the timing plate is just a crank trigger to set initial timing with any advance or retard controlled by a programmable computer with inputs for RPM, boost, gear selection, timers, nitrous activation, ect.

Got a link to your drag bike listed in your sig?

self start - or remote starting

If you are going to remote start your bike with a roll around starter cart / and 1-1/8" nut on the crank-- AND ---- you have excessive overlap in your cam lobe centers . this is when you want the advance FIXED- you also want the idle above 2000 -- this mod is for full out racing tuned drag engines.

the only reason to have the working advancer is for a onboard self starting combination.

I have a stock advancing unit on my dragbike I rev to 11K every shift . I have a nice modified starter motor for the super high compression.

So you only do it if you have to.
