I have been building my 250R for almost a year now. ( meaning I have been buying and stock piling parts when I can afford them ) I have new ESR cases, rebuilt oem long rod, 330 PV with trx 9 port, kit form ESR, 38mm carb. Running race gas. My next things are what set up should I use for the ignition system, Hinson basket and stock clutch?, and should the stock transmission work fine? Is it worth it to get after market transmission. I need to finish this project within a few weeks.

welcome my fellow masshole, were in mass are you from?
yes stock transmission as long as it in good condition is fine,

also OEM clutch is fine there is a clutch modification being done with one 400ex metal clutch plate cr500 springs and aluminum drain bolt washers on each spring bolt

for ignition you have a couple choices but both involve only Honda parts NEVER cheap aftermarket
if you can afford a cr250r ignition its a great upgrade, but nothing wrong with a good original system

I bought new oem fiber discs and soaked a day ahead of time

Thank you, I am from Ludlow. Transmission seems to be in good shape so I will use it. Seen different opinions on the ESR cases. I hope I will not have any issues! I will use the stock ignition for now. I am looking to buy a cr ignition. What should I get from the CR system? What years work? Is there any difference. Jetting will be the next thing.

To the OP....perform a search in this forum on the cases you purchased, a lot has already been written, including any fixes that may be needed. Also search for CR250 IGN 2001....lots of info already posted.

What CR set up would you recommend for my set up? I'm not racing it on a track. Weekend warrior woods and logging trails.

cr250. Either an 01 or the new 02 up kits. If you plan on keeping it a while remember that with the 01 you will have more trouble getting new oem components to keep it going as far as future maintainance-parts repalcement vs the 02 and up kits. New oem 01 cdi's will not exist at all in the not so distant future. Just something to think about.

yes but with the reliability of oem most got 25 years from the stock trx 250r ignition if I can get half of that Im really not worried

ill take my chances on a 01 cr250r just for the preferred timing curve and lack of time of testing on the trx along with extra components to fail that the +02 have at this time

the 01 has been time tested and proven to be very bullet proof along with proven performance gains

The motor is at the builders shop. Thank you for the input. I will go with the 2001 CR250 ignition system. I have been looking on eBay and did not see one. Where can I get one? Also looking for the Hinson case mod w/quick change cover. Should have my wheels in the dirt soon!!

Look around on eBay, or post in the wanted section, they come up used once In a while or a member may have one for sale. The 2002 to 2007 CR250R IGN is still in testing for use on the 250R.

Ok. At the point of jetting. ESR paired me with a 38 mm carb for my type of ridding. Carb came with a few different jets.
