RB Designs Carb Mod for EC300 - Anyone had it done?

[19brendan81]

As the title says, has anyone had their carb bored and the divider plate installed on their EC300? I am going to get my head sent off to get the squish done and figure whilst their I might do this if it is worthwhile.

Has anyone had it done and if so what can you report?

Brendan,

This may not help you, but I had the RB Carb mod done to my KDX 200 and would HIGHLY recommend it - especially if you like low rpm smoothness and throttle control. I'll have Ron do my GG 300 ASAP

Cool. I have heard KDX riders rave about it before and it seems like a logical theory (the dividing bit)...I dont see why it wouldnt also work on a 300.

Im looking forwards to getting my squish done too...between that, the carb mod and the new piston and ring im putting in my bike should fly.

When I got my 11 250 the jetting was off for where I ride. I was just like you, I was going to get my squish done by RB and decided to get the carb mod as well. With that being said, the bike was so much better. It came alive and was jetted spot on. It was like I was on a different bike. I can't can't say how much the carb mod itself made but the bottom and mid woke up and my mileage is much better than before. I love my bike now!!

I had the full carb mod as well as squish done on my 07ec300. That bike started out as a 250 and ran very well on top end but I missed the grunt on low end that my 01xc300 had so I switched the top ends over. My 07 was then a 300 and had good low end but simply would not rev out much on top. That all changed after Ron did his magic to the carb. After the mod it revved out on top like a 250 and would pull stumps on the bottom.

Seems like many people reckon its worth doing. Head and carb are coming off tonight and tomorrow they will be on their way over the pacific to the US of A.

you cant go wrong with that. If you just consider jetting time plus a JD kit you arevway ahead plus the added performance from the mod. It truly is a no brainer.

Update - got the mods done and the bike back together. Also put in a piston and ring at the same time. From the quick squirt I had on the paddock over the road I am very pleaseed. The bike absolutely hammers now...its like chalk and cheese. Hard to tell how much of the power gain was from Rons work and how much was from the fresh piston but the bike is very different now. I could immediately notice the extra power straight off idle, which I imagine is all thanks to Ron.

Havent had a chance to open it right up yet to test out the top end but am looking forwards to doing so. Just have to sort out a sticking throttle first...I near sh!t myself when I grabbed a bunch of second then tried to dial off but the bike hit band instead.
