Motomummy.com has a few sets of Factory Pro Velocity Stacks for the 929/954 for $204.99. I ordered a set today and have already received the tracking info. As you may know these are discontinued and very hard to find. If you want a set you had better not wait too long.

they are hard to come by nowadays, but i'm more curious to see what you think of them once you get them on and ride with them. please let us know!

 

correct me if im wrong but these things dont exactly give you more power, as much as divert it from bottom end to top end. They are also known to increase emissions. one more thing youll notice just like doing a flapper mod is the honk. reviews ive seen say its not worth the money spent. butttttt id love to see dyno test if someone could find one. id could be made to believe ! still it's nce to see a fellow rider looking out for the rest of us

 

Yes, v-stacks are designed to give more top end power. I may get it tuned this spring depending on the cost. Otherwise I will let my drag racing times tell me if these v-stacks help or hurt the bikes performance. I have always preferred using the drag strip. I have made hundreds of passes and know what my times should be so it should not be too hard to figure out if they help or not.

 

I just ordered a set. Been looking for these for a LONG time. These appear to be the billet ones, or so it says in the description, and not the plastic ones. Can't wait to get them on the bike then dyno tune the a/f and ignition. This is the last engine mod I've been waiting to complete before getting it tuned.

 

F me! Someone got the last set 3 minutes before I placed my order.....fml

 

That sucks!! I too had been searching for them for a very long time. There are lots of websites that list them but they don't actually have them in stock. I was surprised when I found them at motomummy. Keep searching the internet and send emails to anyone who lists them on their site. I found the link to motomummy using a google search. It was on like the 7th or 8th page of results.

 

I can't even describe how dissapointed I am about this. I highly doubt I will ever find another set unless one just happens to majically find its way on eBay....which doesn't happen.

 

there were some companies that started making HRC replica velocity stacks for some bikes (like the RC51). they worked just as good as the real thing. maybe look for something like that

 

After calling about 20 online stores, searching the net, etc., i had almost given up. Then, the eBay master backdoc found a set which I immediately bought. Can't say thanks enough man!
