A few 450R Mod Questions
I'm still running the stock filter for now without an air box lid. I plan on going with the sparks filter setup soon. I am going to stay with a foam filter.
I didn't try the hrc cam. The Hotcam seemed to make it pull into the midrange a lot harder and rev out somewhat longer....

Buck, If everyone used your logic, no one would buy Banshees, Raptors, Predators, Z400's. You obviously hold the YFZ in very high regard, but there are a million reasons to buy something other than a YFZ.

Predfan,
I was bringing to light the economic reason you gave. That in itself doesn't make sense after you spend the money for upgrades on the other machine.
I have nothing against any of the machines you mentioned. In fact, I hold all of them in high regard for the simple fact the competition among manufacturers brings us a better product to enjoy.

A few 450R Mod Questions
predfan, i appreciate the fact that u can be mature about disagreeing with me, unlike some people on the forum who would just start an argument. as far as the heel gaurds are concerned i forgot about the brackets. for weight savings, there actually isn't much you can do to save weight on that bike, it has aluminum bumper, grab bar, wheels, sub frame, and swingarm. i didn't mention that a new exhaust would save weight since u said that ur gonna get a new one ne ways. i realize that there r other ways to save weight (headlights, tail light, etc.) but none of them make a significant difference, nothing that you would notice. although i'm sure if u did all of the weight savings ideas at once, u would notice a small difference. that lil issue about which bike is better, the yfz or 450r, it doesn't matter. my fav. riding buddy has a yfz and we've done every dif. type of riding test on both, then switched riders, and we've basically decided that it's all a matter of rider preference. i like the smooth powerband of the 450r, he likes the small feeling of the yfz.

A few 450R Mod Questions
pred fan as far as the hrc kit goes most is a wast but that is the way i went anyway. here are my reasons; #1 brand new machine so the fact that hrc is honda parts #2 the cost really isnt that differnt, a sparks cam $216.00 and a jet kit $50.00 =$266.00 plus shipping hot cams stage 2 $118.00 jet kit50.00 $168.00 + shipping by far the cheepest way to go but you now have a noisy top end, HRC $229.99 + ship.and its all honda. most of the people seem to think the hrc & sparks cams are the way to go. the sparks cam is +2hp on the bottom & -1hp on the top compared to the HRC for me the extra $62.00 was worth it to have all honda parts and a little more hp and a little less cam lift.

blingbling, where did you get the info on the different cam HP #'s? It actually sounds like the HRC kit is pretty good in the mid-range. The pipe mod portion of the kit sounds weak though. I would guess that there are some 450R owners who have something to say on a full exhaust system vs. just the HRC kit exhaust mod - whether a noticable gain can be seen ? I would think that a 2-4 HP increase can be achieved by putting on a good full exhaust system on the 450R vs. the endcap mod from the HRC kit.

predfan as for the HP#s that came from Sparks.as for the HRC exhaust mod. EBAY there are alot of people that just spent $6400.00 on a quad and cant afford an exhaust yet. that way you get $20.00-$30.00 back from your kit. sparks and yosi both told me 4-5 hp over stock from their exhaust, but i dont know what the hrc end cap does over stock. alot of people have great things to say about the dr.d slipon and hrc cam combo. i went with the full yoshi. so if (when) i do more latter it will respond better than with a slipon.

A few 450R Mod Questions
ive talked to a few motor builders at the gnctt's and this is what they said:
1)the HRC cam is one of the best out there...its almost the same power as the sparks cam
2)with a high compression piston, you run the chance of piston to valve contact...even with the stock ignition.
3) hot cams are turds!!

hot cams are turds? sorry but your way off. you sit at your keypad and make statements like that when you probably have never designed, engineered, or produced an engine part in your life. Hot Cams are well thought-out precision ground camshafts, that they offer to the public at a great price. ive ran them in the past and have never had a problem. they do require larger valve lash thus the more topend noise. i just went for the honda part in my Brand New quad.
