has any one out there had their esr engine ported by curtis sparks? i bought a stock cylinder that had been ported by sparks and it was amazing, and now i have a match ported esr 330 r but want to get it ported now. well thanks

 

we are dealers for curtis and eddie and i know curtis he doesn't like to make a cylinder faster with someone elses name on it. if you call their, scott will answer the phone and laugh at you. no one is in the bussiness to make someone else look better. call eddie and have him port it. he builds fast bikes too. he has sold thousands of these motors, he knows where to grab extra hp.hope this helps

 

is that so? well then i got some *** to kick because about five minutes after i posted this message i went and bought a used cylinder that the guy said was ported by curtis himself. hmmmmm keep your eyes on the obituaries.

 

ouch i called up esr and sure enough sparks wont port it. damn i got burned.

 

look under the reed cage intake under the cylinder if it saids trx7 or trx9 or trx5 then esr ported it

 

i looked and it says jpr. which i have never seen before. is there a jpr? or a jp racing? still looks like a nice job

 

never heard of them, but someone on the forum might know. post it and see. then you can call them and see what kind of port job was done (top mid or bottom) i'm sure they havent done too many esr cylinders. i know i wont port an cylinder and give someone else the credit, we are in the bussiness to make are bikes fast not others.
look on the bright side if its fast be happy. port timing can be tricky if you dont know what to do. they must of had some knowledge.

 

ya im not that worried, its fast the only thing is it might not be as fast as it could be
