so i'll be looking into upgrading my 230's motor sometime soon and was wondering if anyone has any experience with these 2 kits and which is the overall better deal there both close to the same price so really performance is the only difference if any? thanx in advance

BBR calls it a 240cc kit, but it is actually just a 233cc kit with stock CRF230 being 223cc. Coeshow's kit is a true 251cc with new sleeve. You will have to bore the case opening to accept the larger sleeve, but the way I look at it is once done, you will always have a true 250cc engine. There is nobody around here to do the boring for me, so I'm just going to send the motor to him for all the work. A solid bump in compression to around 10.5:1 bored to 251cc and a coeshow cam/spring setup is going to give you a decent 25-26hp if I understood him. He says he can make a true race motor that is over 30+ hp though.

I just searched the web for a couple kits with the cam and they didnt have them so you will have to buy a crank and the bbk. I was thinking more people made the kit with the cam, my mistake.

You'll have to shoot Coeshow a mail and ask about his kits. You can have about anything done, and he loves the 150/230's sohe has done, tested and dyno'd them with his kits. I would love to sit on a 32hp 230 and see how that feels!:thumbsup:

Just read the thread. He wants to know if the 251 Coeshow kit produces more HP than the BBR 240cc W/ BBR Cam. Not exactly sure, but don't think the Cam/springs are necessary. I don't think you can buy any kits that actually come with the cam. However, there will possibly be a matching Cam for the kit. The only way is if it's a complete "stage" style kit. A BBK alone will not include the Cam.
