MAD, you may want to run a search on the forum. I seem to recall discussions that indicate the 240 has some serious vibration issues. :ugg:
Beyond that, maybe just call Eric. I have no personal experience with him, but everything I have read is positive. He'd probably give it to 'ya straight.
my 240 has won many races since 1996. Eric Gorr did a wonderful job with it and it has been very reliable. Big power but not too much. Hope this helps.
Jay: I've done that, or tried it's either busy or no answer. I've sent a few emails that have gone unaswered. I had asked him last year and it took like 3 months to get a reply and I was skeptical of sending my top end to have it worked on. I'd prefer to buy the kit up front :D
Gumby: Can you address any vibration issues ? Did you keep standard jetting ? Was it pretty much a simple bolt on ? Did it include new/reworked powervalves too ?
