I am soon going to be getting my 107 built and was wondering if the standard clutch is going to be able to cope. With the build I should be getting around 115 rwhp. I have been known to do the occasional burnout and power slides ( on closed roads ??) and don't want any issues. 

just do the upgrade then ride it and see how it goes, a bit of clutch slip does not hurt.

I learnt a lot drag racing and riding on the street and riding to race.

I ran a stock Harley clutch with screaming eagle pressure plate so was heavier than stock but still stock clutch plates I used auto trans fluid type f in primary. I was runing low 11's with best 60ft time 1.65 this was a dyna twin cam best trap speed was 121mph in 4th averaged about 119 to 120mph depending on air quality on the day. best time was 11.2. clutch slipped when I shifted to 5th gear, so I just held 4th gear. latter I payed out som $ on an s&s clutch I've also owned a bandit super clutch ( probably best I've had but the s&s was good but I gained zero, no quicker no faster.

about to do my old 03 sporty motor & gear box up but will leave stock clutch see how it goes ( sporty a bit lighter . bit of clutch slip takes stress off belt n gear box.

if you find you have too much clutch slip just leave the stock pressure plate spring put a vpc pressure plate in they increase pressure as they rev and you have a light pull.
