Boyesen 607 reeds or Delta Force reed valve

[lee42lee]

I am sending the head and carb off of my 2001 KDX 220 to RB Designs and I am wondering what everyone on here thinks would be the reeds to install the Boyesen 607 reeds or Delta Force reed valve? Thanks for any help.

If your spending that much, I'd personally go the extra and get the Delta Force.

My local mechanic/expert/friend highly recommends this product, and he usually doesn't recommend much of anything. He usually just keeps silent on most aftermarket stuff, because it rarely impresses him.

I just put the Delta Force on my 200, and just a quick run up and down the street, I noticed much better throttle response. Saturday I'll have a much better idea how it feels, but so far, I like it.

Both are great upgrades... I have a DFIII on my main bike and 607's on my spare. If I was to replace them due to damage, I think I would go the 607 route. The only noticable difference I can tell is the DFIII is a little more noisy. Just my opinion.

anyone else care to comment. i'm about to buy a set of reeds for my 2003 kdx 220 before sending my carb out to RB. Thanks.
