If I had to do it over again I would not have went the with a 300 cylinder, there is a lot of good tuners out with experience on the yz 250, Tuna is right a stock bore 250 is hard to beat when ported correctly, 300's are flat on top, yes the bottom end is a little better, but a 300 kitted yz is not a 300 ktm, and it will never be a 450 or even close, just getting s stock yz dialed in, between cutting head, dialing in jetting and timing, and getting pv working correctly, they run well. I have ridden a few different yz 250s with porting from different tuners, they all had some Benefits, I have two cylinders ported for my yz, they both work good, it's like a stock yz but on steroids, I usually change piston and rings at 40 to 50 hours, stock bore piston is easy to get, they run on 100 octane, everyone has a different opinion, from my experience a stock bore 250 runs very good.

This has been my experience as well with the YZ250. Most big bores I’ve ridden do have a flat top end feel. It will be a trade off unless you have the engine built with a different stroke to compensate. An 04 model owned with PC cyl. & head mods was the best set up I’ve ran to date.
It did have a better low-mid rpm range with a slight increase in the top end.
I was expecting more up top so I talked to the guy in charge of the engine dept. at the time (05). His response was it’s hard to improve upon the oem cyl. porting specs & engine design.
Have an 06 model I’m currently working with & feel it could use better low end response so I’m going to try different jetting specs. for now.

OP something to consider. The low-mid can be improved upon with mods, but you’ll have to run higher octane fuel.


Forgot to mention I spoke with Eddie a couple of times in the last 3 yrs. & left him a few messages about wanting to buy a 325 ESR kit for the 02-07 CR2. Unfortunately it never happened so I finally gave up. I think he does a lot of the work himself so he’s spread very thin.

Great info, thank you. Eddie got back to me pretty quick. I'm really looking for some nice low end grunt with a solid midrange punch. I'll give the ESR kit a go. Im planning on using a DEP pipe, BUDs racing CF can, VF reeds, 9 oz FWW. Should be at the very least fun.

I believe you can run his 325 kit on good pump fuel ?

Talked to SDTony ESR about a yr. ago over the phone & he had some good feed back on the kit. I know he gets a lot of crap on this forum, but he is just another moto guy like most of us on here. With the exception of the TMZ gang..

I think you meant TMR gang

Tom is a little more then a moto guy, he is a legend, and was a factory mechanic with a great resume. There is a reason Tom, Varner, Mitch and some others get praise, they do great work. I've seen a lot of ESR reviews and most of it so-so. I'm sure it could be made great with a little port tweaking, plated cylinder and some stroke. For the price, I can imaging the ESR could make a good woods bike with it favoring low to mid power. I noticed the ESR kit price has dropped significantly.

I met SDTony while we were racing at Straight Rhythm. He is in San Diego as well, maybe someday we can swap bikes at Pala and do a fun little comparison!

(PS. ESR should change his home page picture to Mike Alessi racing the ESR. Dune riding pic with jeans seems out of place for moto guys)

If you refer to a proper running 250 as "lame" then I don't think you should be dishing out advice on engine configs IMO.
