Hey Monty,

Can you describe the differences between these cranks would make in a 3 port or 5 port - 15007T, 15009T and your 15009HT :D

Next question for you is what size is the rear bearing in the N21BF? 25,4 or 25,8 - I am guessing the 25,8 but there is not an exploded parts page any where for reference :(

Thanks!!

the tuned crank really doent need a "mod" , i dont know why but i just dont like to be called a "modder" . a tuner sounds more appropriate to me ;)



send me your stuff wes , the work will be free , you pay the shipping ;)
and no i wont do that for everybody , wes seems like a really good guy , had a few pm's with him and i am feeling generous today


send me whatever you want and let me know what you wanna do with it ok;)


my number is in one of the om's i sent ya i believe:D

Thanks!!

The fms is 14.5x26x6x6.3mm offset inner race
N21bf is 14x25.4x6mm

As far as the cranks they are all very similar , the tuned versions are basically hand finished and there is timing advancement and intake duration length ground into the crank opening .

Thanks Big Guy -

So it is all about timing and duration - I need t learn more about these little motors and the principals ..

I noticed you don't have the RB AR/Oil listed on your site you were showing me - should I just give you a call when I need some?

I'm going to throw that FMS with the different crank into my Truggy to see how it runs - I know the track is short but I am curious to see what it does - which of those pipes/header combos do you think would be the ..um .. tamest of the bunch?

So what bearing is that in the FMS use one of the 16002/4 or is it something different?

9853ss :nod:

the timing/duration has quite a bit to do with the engine , yes sir :D

FMS bearings :
bearing 1

bearing 2

bearing 3 this is the bearing that was coming in the fms engines

the best front bearing on the market!!

theres one more thats not listed that comes in the toro and now comes in the FMS ;)

stick with me , i can probably show ya a thing or two ;)

thanks jeff,
