It really matters on what kind of riding you do, I live twenty minutes away from Glamis, Buttercups. The 13 t I definatly recommend unless you have lots of mods, that is what I use, but my brother uses the stock gearing and does well to, he also weighs 40 lbs less than me, I am about 175.Originally posted by Speedbump@Oct 5 2004, 01:03 PM
Danny, you can go two routes with the sprocket. Either drop the front or add a few teeth to the rear. It takes less power to run the stock front with a aftermarket rear. 12t front with a 41 or 42 may be the ticket after reading one of Rico's posts. The HRC cam will work but you may consider others if you want to do Hill Shoots, or unless you have a hi comp piston. In Oregon alot of the hills dont give you alot of room to get to the topend of your motor where the HRC cam shines IMO. What ever you do do not get any V paddles, they wont do anything for ya. I recommend Haulers or extreme haulers. Also adjust your suspension, there can be alot of whoops in the dunes. Any exhaust will be an improvement over stock and will help you alot to power through some of the soft sand. Also alot of people remove their skidplates to avoid getting stuck.
kgb, did you have to lengthen the chain to use the 39 tooth sprocket? i run a 13 tooth counter,hrc kit w/185 jet and duncan pipe and a vortex cdi. the 13 tooth does good on the hills but i think it may be a little too low i raced trxjwb and his brother and they pull out in front of me right off the line about 3 bike lengths, we switched bikes thinking it was a weight issue but the race was still the same im thinking the sparks aggresive cam may be a little better than the hrc for hill racing. so i put the stock 14 tooth back on but it will bog down a little in 3rd going up hill so i was thinking about getting a bigger sprocket in the rear to make it be in between 13/14 toothOriginally posted by KGB@Oct 5 2004, 02:41 PM
I ride strictly sand.
First things first:
Get new a arms and shocks, and at least a axle for the back. The width and improved suspension, makes the largest difference by far, of any of the mods I have done. Other that that:
I run 14/39(one tooth larger in back). I run a 20x10x10 7 paddle haulers. Not a hillshooter tire, but the best all around tire, for fun riding. If you want to win hillshooting, go with a 22". I highly recommend the FCR carb. It makes is so much funner to ride. I am running a DS650 intake and filter, no airbox. It helps alot with air flow. I have made a nice aluminum bracket and it mounts to the old airbox holes. I run the HRC cam, and am currently trying to decide if I want to stroke the crank or just go with a big bore.
I have tried many different tires, sprockets, tire pressures, widths, and I am pretty confident that I have mine set up exactly how I want it. You might be different, but I bet you find you like some of the settings I am running.
Sprocketing down is for trail riding. I love stock gearing for the dunes let her rip. On my old 400EX I always started off in second in the sand. The HRC kit also opens up the top end which is where dune power is. HRC, and pipe and you should rip up the sand. I soften the front shocks for sand.Originally posted by trx450Rrider@Oct 5 2004, 12:56 PM
i dont ride dunes but i know that a 13 tooth is almost a must for a bike with the HRC kit so u can get ur bottom end back. stock you should get it also cus if not you will bog down going up hills with those long gears
I hear this quite a bit from people and I just want to state that 8 paddle haulers can be used for carving and sliding (see example below ). I'm not saying KGB is wrong, just pointing out that it's not impossible to have some carving fun with them, you just gotta learn how to shake your tailfeather if you know what I mean. For me, I not willing to give up the ultimate hook up and acceleration that the straight blades give. However, if you are concerned with the sliding ability of the straights, I'd have to say that the Sand Stars are the best v-blade out right now. My nephew has them on his R and I was really impressed with how they perform.Originally posted by KGB@Oct 5 2004, 05:04 PM
.......... 8 paddle haulers hook up straight, and not very well for turning...........
OK, I'm with ya. I've never tried 7 blade haulers, but I believe your feelings that they would slide better than 8s. I have tried 9 paddle haulers, and while they were great for straight line acceleration, well, they were great for straight line acceleration.Originally posted by KGB@Oct 16 2004, 10:47 AM
Bad Habit, Danny,To, be more clear, I HATE V BLADES, and I have found that I prefer 7 paddle haulers to 8's because they slide better.
