I recently found out that ESR is located about 10 mins from my house. I have a 250r and want to get a 270 kit and some port work for MX and just regular riding. Should i trust him with my work because i know nothing about port mapping or anything.
thanks

 

I don't know much about his ATV work, but his Micro-Sprint work is excellent. He is probable the most respected name when it comes to building a micro sprint motor.

 

I don't have one of his cylinders, but I have the ESR TRX5 pipe and love it, head and shoulders better than my LRD pipe

 

i would trust him i have az esr pipe on my pipe and when th epower band kicks in you better hold on. as the other guy said he is really respected when it comes to micro's. most micros have a cr250 motor in them with is rather similar to the trx250r motor. i have heard nothing but great things about him and his work
