Hopping Up a yamaha wr450???
Posted December 23, 2007 - 09:39 AM
I typically ride from '8000 to 14000' here in Colorado... Using rough numbers you can only expect about 76% of your rated HP at 8000', 68% @ 10,000' and 60% @ 15,000'!! Think about that.....how would all you sea level guys like to wake up tomorrow and your bikes have just lost 24-40% of your bikes power?? I bet you would be looking for ways to get that back...
I would like to ride my bike a little longer to see how the FI situation comes out and would like more power without spending a fortune.....are there any real world reviews, comparisons or numbers out there to tell me what kind of power increases I will get from a new exhaust or cams or big bore kits?
Thanks and Merry Christmas!!
