If this is the case how does the splice mod liberate more HP? I dont understand My NSR will have the splice mod but i wont be doing anything else and it will be completely stock, the supplier tells me that he does the splice mod on all the NSR's that he imports.
an engine with less ignition advance has less power basic so an engine with more advance has more power still basic but the more you advance timing the closer you get to pinging still with me the leaner an engine gets the closer it is to pinging or melting pistons. doing the splice give the engine more advance in the top gears were the engine is under a lot more load and also more power in these gears this added power and advance will need more fuel to run the cylinders at the same operating temp this is the same for all motors.
the splice gives more advance and an actual advance curve in the top three gears
so your going to give the bike more power and advance as well as making it leaner by drilling the air box but not add any more fuel id say its a rebuild waiting to happen although would probably be fine under 3/4 throttle for a while although i wouldnt risk it "a dyno run costs like 80 bucks"
