Does anyone know what VForce reed block fit the dt400? Also any first hand experience with them?

someone on here just put up a video of his RT3 running with a Vforce reed block. Bigger block on the 400 though. I'll see if i can link the page.

Scroll through that to the video although not your model.
Seems like a great idea those.

I fit VForce reeds to my 77 DT250.

I was recommended by MT to use part number V301C for my 77 DT250. You'll see there is also a version of this sold as part number V4R01H that has full length reed stops.

I used part number V4R01H with no modifications needed to my DT250 when I rebuilt it. So far it has run with no issues, but the bike wasn't running when I first got it. I have no idea what it first ran like before I tore it down to rebuild. I also have a VAPE system installed.

Hope this helps, I'm pretty sure the reed blocks were the same for this year on the 250/400.

V401H is the same part number I used on my rt3, I did have to grind out quite a lot of metal to get it to fit.
