I'm sure this has been debated in the past but some of the Dynojet kits are not available for the F2 anymore.
So what do you guys recomend.
Dynojet Stage 1 or factory pro?

Bike is a 92 600 f2 danmoto slip on and K&N filter. Has a flat spot at 4k rpm in the current set up which I have not looked at but the previous owner thought was stock.

 

check ebay there are some NOS dynojet kits up for sale... you could also just shim your stock needles with .5 shims and that may help ..

 

^^^i second that, don't waste yo money on a jet kit like i did

 

I ordered the Factory Pro kit.
I think the needles are pretty spanked anyway so it'll be good to do the refurb. It was mighty pricey though. 150 with shipping I think.

 

Factory pro uses standard jet sizing if you ever intend to dyno tune the jetting on your own.

I used a dynojet kit on my F2 when I had one. Worked great and had no issues.
