Adds 2mm extra room!
Jim
What about a 2095 AND the copper washer?
The 2095 rack plug is actually about 4mm deeper then the stock plug. The rack does not contact it, the internal rack stop is what actually stops the rack when a 2095 is installed. I would not add an extra washer, there is a chance that the rack will hang due to how it is designed. It would be wise to spend the extra $12-$15 to do it properly.
If your worried about 2mm more rack which is slow fuel anyway, why don't you just do more pump work and have quicker fuel rate.
