05 CR250 R rebuild

[oldschool]

A buddy of mine had this bike sitting in his shop for a while, he got it from a kid that was using it for freestyle stuff. The thing was pretty roached, but price was right and a lot of my 06 CRF450 parts switched over. I took it to the track and it ran pretty good(might need a few carb adjustments) and suspension worked well. I'm going to ride it a bit more to see if its a keeper. Bike got new plastics, airbox and filter, Mika bars and grips, Wiseco top end, Boyesen carbon reeds, new SDG seat, DNA hubs and a few bling items.

Looks like a nice project!

I love me some two strokes.

Thanks.
Those hubs look familiar? And forks/triple clamps.

That was the 1st thing I noticed [emoji12]

I love the smell of burnt bean oil in the morning!

Me too! Haven't been on one in a while. It really makes me realize how slow I am.

I came off not having a dirtbike for years, but off an 87 YZ 250.

This ol girl straight gets with it and has the the suspension to boot.

Right after I got mine, my lovely wife and I were watching X games, or something similar, on TV.

Hey @oldschool do you have any plans to do a Keihin Airstryker swap? My new RM250 has an Airstryker with TPS on it and I am toying with the idea of going lectron.

If you like desert riding mixed with some mountain riding, I've got a place on the back side of tehachapi we take jeeps and bikes. It's all private property so you don't run into too many other riders. If you're interested i'll let you know when we'll be out there.

Should I be? What's the benefit? I don't anything about the carb options for this, so maybe. Let me know what your thinking or want for the carb. Thanks!

That sounds awesome, unfortunately I don't get much time to ride any more. I try to sneak out to Tulare every now and again on the weekends. Thanks.

It's a pretty common swap to pull the mikuni and add a kehin. From what I have read, it is easier to jet (read less picky) and helps you get more power on the bottom end.

It is, however, widely accepted that if you are going to keep the mikuni you should sent it off to Chad Watts of Watts Perfections to tune the carb (he was RC's motor builder when he was at honda)

Gotcha. I've ridden it twice and so far the jetting seems to be "ok". But it definitely would benefit from a bit more bottom end. Mostly, I need to stop trying to ride it like a 4 stroke.

General consensus on this era CR is that you have to ride them like a big 125 to get it to work well (assuming no motor work, a lot of people will mill .030 or .010 off the base of the cylinder to help bottom)
