reeds that is  i run the 12, 8, 6,and 1 pedal reeds through the engine simulator. h1 500 stock ports same carb size same WTF exhaust same everything this simulation engine was run as a crank reeded motor and a intake reeded motor only difference is the reeds crankcase reeded motor the 12 pedal reeds made 14 hp more at 8500rpm over the one pedal the 8 pedal reeds made 12 hp more at 8500rpm over the 1 pedal the 6 pedal reeds made 6 hp more at 8500rpm over the 1 pedal the same reeds in a port intake with stock port dimensions the 12 pedal 8 pedal and the 6 pedal all make the same hp as the 1 pedal. this is due to the fact that the port can only flow so much with out mods. so anything bigger then 4 pedals is a waste of time and effort and $$$$. |

so jamming reed boxes on to the intake on a stock engine only benefit is they improved bottom end. givers 500 non reeded and my 500 reeded both pull the same on the top end. mine just pulls harder sooner. so spend countless hours manufacturing boxes then spend $500 plus dollars for cages and pedals or buy them bolt on from moo and go riding for $ .don't know how much he charges but I'm guessing around $300 bucks correct me if I'm wrong moo.

However, Perhaps you should re calculate the effect of the two additional transfers on the rear of the cylinder typically installed with intake port reeds?
Secondly, what sort of numbers do you get with transfers raised 2mm, Exhaust raised 4mm, two .5 in holes in piston skirt. additional rear transfers .5 below main transfers, 34mm carbs, 1 petal reeds, WTF chambers all on an H1?

J Here is a dyno run very close to those specs. Just a bit hotter than Walmsey's motor. And banshee (yamaha) pipes...... And my stage 2 conversion kit is $379.00, with install and 6 boosts is $630.00 complete.  |

Good guesser, I guess............ And for the guys that do "frequent" the "B" board, you probably know I do not post there. And to "quell" one of the lies being spouted there. I have posted flow figures probably 6 times through the years, they were conviently "ignored". These flow figures were done by a very experienced tuner that has been flow testing for decades. He is a friend of Kevin Cameron and on the same level of experiance as far as I'm concerned. As you can see it's pretty old, and actually a test of a earlier, smaller version of my stage 1 750 kits. And I wil be happy to answer any questions..... Here, or in PM or E mail.  |

And my stage 2 conversion kit is $379.00, with install and 6 boosts is $630.00 complete. Those curves are bang on to my butt dyno tells me...lol Actually I think mine starts pulling at 6 then starts pulling really hard at 7 so I suspect my curve will look a wee bit different. I might need to break down and just go to a dyno.  I got my Veypor unit re-installed last night... Fookin thing is still giving me fits! I have to go back and double check my wire taps, the stupid thing keeps resetting  Have I ever mentioned that I fricken hate things that require electricty to function? |

the piston port engine does have 2 additional transfers and windows in the piston LC. the intake port will only flow so much.so without opening it up your not able to get the multiple reeds benefits,but in a crankcase reed set up you can extract all the flow they have.to transform a triple into a case induction is a whole lot of work and money for someone with no machine shop behind them.
the 1 pedal reed of moo's did exceptionally well seeing that it is only 37mm wide compared the the others that are 60mm x 2(6 pedal) and 60mm x 4(vforce 12 pedal) and 75mm x 2(8 pedal)

How long will a bottom end stand up to the extra HP? I realize thats a fairly vague question but it looks like almost double the stress (and triple the fun)

H1's are very reliable up to 85rwhp...after that (drag) they tend to lose big dependability.
Not that you can’t go higher in hp…just take note of your machinists phone number and be prepared.

You only need reeds if you want to be like a Yamahahaha...think some of you guys belong on the yami forums. Don't need no stinken reeds  |

Don't need no stinken reeds I personally like the rgv rotary valve setup. It's cool to do more performance wise with triples, but again, probably the biggest performance impacts anyone could make is to simply put the fork down for 5 minutes. |
