Anyone on ever tried this set up v-force reeds + spacer

[400exrider69]

I"m rebuilding my 2000 kx 125 I'm ordering v-force reeds for it. I've read that reed spacers add more torque would it work good to add v-force reeds and the reed spacer?

Would have my cylinder polished help out for xc racing ?

Has anyone got anything from SFB racing they have 9oz fly wheel weights for my bike for $70 i'd perfer to go with a stealthy but $ wise it's cheaper

I ran the v-force with a spacer on my LT250R years ago. Could not tell the difference between spacer/no spacer. Stock bore, midrange/MX porting, 36pwk carb, fatty/power core.

Reed spacers are a waste. Stick with just the reeds.

And what do you mean polished? You won't gain any power unless it's actually ported. But if your exhaust is starting to get clogged with carbon, yeah, clean it out.

As most already said, reed spacers are a hoax. They don't do anything worth noticing. Save your $30 or so and buy some oil, gas, and jets. The vforce isn't a bad setup. I'm not a fan of the 3's with the snap together cage. I've seen quite a few break. The 2's are a screw together design. I like them better. Don't for get to rejet for the new reeds. If you just put them in you my not even notice a difference. I've found that the boyesen rad valve is a better setup then the vforces. The boyesen requires a fair amount of jetting to find the "sweet spot" with that set up, but definitely runs better than the Vforce's.

I went ahead and ordered the v-force 3 reeds i had them on a cr 125 and worked good but was already on there when i got it so i'll have to see how much to rejet

Still wondering anyone heard of SFB racing at all??

Bought covers from them. They were actually pretty nice.

thanks i'll go ahead and order it and see how it does after i get my top end rebuilt

[400exrider69]

well i got everything but bottom end apart i'm thinkin that the gasket or silicone that goes between the cases is junk and i've gotten some anti-freeze in the oil i found a bearings or seal like sitting side ways in water pump
$$$$$$$$$$ is all i can say i'm figureing $1500 in rebuilt

ebay is your friend. You can find new parts pretty cheap on there. If you're finding antifreeze in your oil, most likely it's a water pump seal. Every kx I had ended up eventually having a bad water pump seal.
