It was just a picture of a KDX 200 on the dyno.....

 

And YOU are wrong it's a 1996 KDX 200

 

As all of you closed minded people that won't look at anything that has not been approved from the Planet Sand Guru's......, I'm so glad that you all have the after market cylinders, billet lower ends and stroker crankshafts......, you all should be so proud of your 10K + engines. So you really don't need reed spacers now do you?

 

I was simply wanting to give an option of what I have found on the 350 Yamaha twin in some what stock form and reed spacers......, take it or leave it. I do have a Dyno and have tested lots of things....., do you or do you just read about it?

 

I'm done....., so I will not insult your bench racing and reading. You have already have your gospel opinions :notworthy:

Good for you iceman,

 

And I'm sure they are all stock cylinder bikes with stock reed cages that use reed spacers on the cylinder side......., I am just so dumb :shrugani:

 

Just no putting something past all of you Pro's :cry:

I'm going to have to back RBD on this one guys. He was simply stating that from his experience reed spacers on the carb side were good for some additional power. I'm always one to want to confirm something before I go spewing it as gospel, so I can't say he is wrong or right. And I will add, that just because a group, however big or reveered, says that it won't make crap difference, doesn't mean they're right. There are so many variables when it comes to engine design and component combinations, that it may not make a bit of difference on your bike with your setup, but it will make 1.5+HP on mine. If he's seen it I can't say he hasn't just because I didn't see it, or somebody tells me it doesn't. And true, I know lots of bench racers. I come from the car world, and let me tell you every toothless moron has a 425HP small block chevy. Sure makes my honest 385 HP I built sound weak, but truth be told their's is lucky to make 250. That's my nickel less three pennies worth. ;)

thanks for the info about the rd 350 and reed spacers. its good to hear more than what the guys on planet sand say. i dont have a 10mm cheetah mill and its not worth 10 k to me to get one. it is interesting to check out planet sand but im in a different world

I wasnt trying to disapprove what you were saying. I simply stated that I know that some people with very fast bikes DONT use reed spacers and have probably tried using them and didnt get the results they wanted. I never said that adding spacers on the carb side was a bad idea on a stock engine either. And I will probably be getting some reed spacers and putting them on the carb side if they do give more up top because I have stock cases and stock cages. Damn. I never said you were dumb either.

To anyone that may be interested, I have done quit a bit of dyno testing on reed spacers. The engine used was a Yamaha RD 350 production road racer which is a air cooled engine (which is basically the same engine used in the Banshee, case design and ports).

 

When putting on the reed spacers on the cylinder side, the engine lost 1 HP on the top end (as apposed to not using the spacer).

 

When the reed spacer was installed on the carb side, the engine put out 3 HP more on the top end (as apposed to not using the spacer).

 

Thank you,

So if it was worth 3 HP on a stock air cooled twin up top what would it be worth on a mildly ported V-forced piped twin?

5-7hp? even 3 would be good. i have a set of 3/8 inch reeds just sitting.

 

Or what about a full drag ported engine with stock cylinders CPI's and 35 pwk's?
