The stock clutching with appropriate weights works very well also if you don't want to invest a bunch of money in a whole new set-up. You'll probably end up 2 to 4 grams heavier than stock.
I ran this kit last year for 1200 miles. Loved it. Go to bikeman and pick up stage 2 clutch kit. Also call them and ask Joey what he recommends for your elevation. Pm if you have questions our team rides their products and knows them well
