All about reed spacers - one of the best mods

[ToomanyKaws]

Installed the Moose spacer.  Bike already has a set of Boy. dual stage reeds.   Seems smoother.  Amazing how desert riding in the tight stuff how fast you can go on 1/4 throttle or less most of the time.   My buddy swears by the RAD valve and V-force.  Has one of each in his bike and his brothers.   Told him the RAD is " right in Dumpster".   Stock would be better and more reliable.   Says no way, gained more power with it.     None of them can still beat my 02 KX500 that has only a pipe, stock gearing and the reeds.   Like the excuses they come up with.   How me being 150 pounds is not fair.   Going to work on my suspension next.  Bike has more than enough power for me as it is.

I know this is an old post but here goes, when adding the reed spacer, is it also posssable to add a scary fast modification, or is that deffeting the purpose? I like the idea of adding some bottom to mid range but refuse to give up top end and over rev.
any ideas? if it helps..which comes first the reed spacer then the scary fast mod?

I to know this is an old post,but I have to jump on the Moose band wagon as well.I installed mine and noticed immediately that I could stay one gear higher in alot of situations.I had a '90 that was bone stock and it pulled better off bottom than my '92 with Gnarly and flywheel weight until I installed spacer.I didn't really notice any top-end loss.I'm also going to try a 15 on the front.

Installed a jfabs reed spacer with the vfore and i must say i like jfabs better than the moose for the k5.  The moose spacer did not fit without shaving alittle but jfabs fit perfect.  Great upgrade.

5MM or 10MM?  Someone on ebay selling 5 and 10 mm spacers for the 500.  I am considering a spacer to be used with V Force 2 reed block I just purchased.  Will I notice a difference?  Which one?  Is the V Force 2 enough as a stand alone unit? Let me hear your opinions!  Fitz

I run the Vforce 2 without a spacer and the bike performs very well. I have sold them to plenty of guys running the V force 2 reeds. Maybe some of them will chime in and give a report for you.

On my 88 I used the 10mm spacer with the V-Force 2, but the top of the carb hit on the frame so I took it out. The V-Force 2 seems to do a great job by itself with no spacer.
