Going to try a heavy duty starter for my '07 FLHTCU with the 103/255 cam upgrade. Anyone used the ULTIMA Thunderfire heavy duty 1.75KW starter for this application? Will it bolt in place of the stock starter without any hassles? States it is 3/4" longer than stock, is that a problem? Seller says it is not a problem, but then again, they are selling, not installing and using.... will it clear the oil cap without interference? Does it come with every thing needed to undo my original starter and put this one in its place? Or do I have to invest in other parts before it can be installed? Also considering buying custom heavy duty battery cables better than stock just to help the cause, even though it states stock battery and cables are OK. Need both cables or just the positive cable replaced? Any suggestions (other than the obvious alternative....compression releases!!!) ??? thanks, PACO
