Nope....

Wook, that silver dome looked a bit like detonation, camera angle?

something crossed my mind. i know some of calvins cylinders use cr500 bolt pattern on the reeds. ill bet these vf3 were originally designed for his shit and they probly have larger throat. douche bags at mototassinari knew they would half ass work for a cr500 motor so they threw some new badging decals on the box and put them on the market. when you look at how tight the flaps are and how out of whack the stuffer is then it all begins to make sense. no fukin way they were designed from a cr500 cylinder.

I don't agree that they made it fit calvins stuff he is a small fish in a big pond.

If you look the replacement reeds are the same for almost every VF3 reed cage they make and really the 2's where the same.
Some motor designs benefit some don't when you make a generic size fit 90% of the motors.
Its to bad someone doesn't make a billet aluminum version with custom fit reeds that was optimized for the 500 its self

i'm looking for billet, I have guys that'll make the reed pedals in whatever quantity needed.
It'll need to be made properly on a 5 axis cnc tho, blended from the carburetor to the pedal tip as 1 piece

maybe boyesen would be interested in making a cage. anyone called to see what they have to say ? they have the equipment needed.

Ya that'd be great if they'd move away from that dual-stage gimmick.

im sure theyre no different than wiseco or any other company. you send them money and they make whatever you want

you can run single fiber glass or carbon fiber reeds rather than dual stage. got it both ways on the ktm's. one has single fiber glass, one has dual stage. night and day difference which one reacts faster to throttle changes (single fiberglass). i dont have any single carbon fiber pedals to try.

eddie sanders of ESR makes billet v-force knock offs for the 250r's wonder if we could get his supplier to make them.
I know modquad made the coolant temp gauges for ESR at one time maybe he would be interested in doing it, they make allot of billet pieces infact Mike who owns it is suppose to be making me some custom billet axle hubs for my titanium axle. To bad I have been waiting for more than a year and a half. Man that pisses me off now that bring it up

Www.mossbargerracing.com

These guys make a aluminum reed cage that out flows all of them ( thats what they say) looks like a modified stock 8 pedal cage so I don't know how much better they are over stock I'm sure there is a improvement but where?? It flows more air which means to me a slower velocity at lower rpms means less John Deere torque

Someone on one of the sites had one can't remember who it was anybody tried one of these

I heard of Mossbarger a while ago. But do they outflow VF2/3 reeds?

I think they build shotguns too....

thats mossberg, and mossberg just happens to have Jacks christmas present in stock

They say it does???

They show the cfm each one flows

Mossbarger
Boyessen
Vf2

i'll have to setup and flow the new reeds i expect to arrive next monday compared to the vf2 and 2 other setups i have

I checked their site and didn't see VF...maybe I missed it. I saw Boyesen and FMF, and stock.

Looking forward to your test results, Roosty!

Any luck with the low end pull yet?

Is elsinore the same race that is in "On any Sunday" ?

So? Any results? Inquiring minds want to know!

Heres some better photos of my teardown.....


Intake side of cylinder looks near new......


Exhaust shows some wear, digital camera is adding to the effect


Underside or piston shows some heat stress. Black spot in the middle is pretty common, discoloration going all the way out to the edge of the crown is due to many flat out runs across dry lake beds... some pretty good heat!!



These are some telling photos..... now remember this piston is 4+years old and shows almost zero wear. The only wear visable is from where hot combustion gas has come down through the ring end gaps and blown the 927' off the cylinder wall. The top ring gap shows the most wear, the second ring slightly less....No blow by, no varnish, ring lands absoultly spotless, no scoring of other Wiesco type shit.

None of these parts were washed or cleaned in any way... its exactly how they came out. Vertex = Good.

Compare the skirt of this Vertex that has gone up and down the cylinder 5,000,000,000,000 times..... to this one thats only gone through a cylinder twice...


Which one do you think fits the bore correctly??

Any questions????

What type of piston does Ur buddy with the Rustang run?

ive seen the burned shit on the underside of a few of mine. did some research and its sometimes refered to as death ash. from what i gather the crown gets so hot the incoming charge gets scorched underneath.

Yup, when your makin some power
