Ims " xr300 "

Recommended Posts

Hi fellow XR riders..

*I'll be updating this thread, probably with a different format/layout.. right now, I just have some general questions and maybe a little show and tell.*

I picked this bike up about 5 months ago... kind of a short but interesting story of how I got it, but, it doesn't matter.

It's been sitting in my storage unit for about that whole time since I bought it, I recently went back to CA and picked it up. Now I need to fix it up and see exactly what I bought. (I had the bike for 3 days before I had to put it in storage). It was running when I bought it, I actually rode to AAA to do all the paperwork/insurance... when I brought it home to TX it ran. I let it sit again for about a month, I tried to start it up yesterday, and no startey.

Here's some specs:

1997 XR 250R that used to be owned by IMS(or one it's riders) and is very tricked out.

It's CA street legal.

bored out to 290cc

Mikuni pumper carb-- I have a question about this.. please see below

Stroker exhaust system (I think this is a Pro Circuit company?)

talon hubs fr. & rr.

Aftermarket clutch basket (Hinson? )

Devol Frame Guards

Basically anything IMS made for the XR250 is on this bike.

1997 CR250R Front end.

Has "hot start" system

I'll update as I find more to add.

If anybody has info. on this bike or stories, feel free to share. I vaguely remember seeing something about it online or in a mag a long time ago.... so, when I saw it in person, I had to pick it up :busted:

Here's some pics.

This bike was featured in a Japanese Dirt Bike mag, which came with the bike... I can't read any of it. These pics of the bike are from the mag... Mar. 1999 issue.

Can anybody help me identify this carb?

It's a Mikuni, and from what I can see, it's a pumper carb.... I'm going to be rebuilding, at least cleaning and re jetting, but, first I'd like to know which model this is..

I bought the bike about 5 months ago...been in my storage unit for about 4 months.

I didn't pay the full $2900 asking price, but, it was around in that ballpark. (this is where the short and interesting story would take place)

I'll definitely have fun with it once I get it running again...

Add XR 400 oil cooler to the list of goodies...

forgot to mention.. it has one of those also. :busted:

first thing I noticed when I went to look at it... ("OMG it already has that oil cooler mod done to it", I thought)

it's plumbed into the frame like my 400, not sure if that's the conventional way to add the xr400 oil cooler.

got it running today.. basically took me 4-5 hours to clean a carb, I suck. A pretty detailed cleaning, figured out what jets/needle I have etc.

(first time I've had this bike apart at all to my defense)

Found out that the carb is the Mikuni 33 8012 (pumper)... I guess those stamped #s meant something.

I'm pretty sure I have a leaking head gasket, but the bike runs "well".

(I see caked oil/dirt in the gasket area right below where the headers are located)

stoked.. didn't plan on messing with it for a while(next weekend or after thanksgiving).. just started doing 1 thing after the other and got it running.

Now hopefully, it'll start tomorrow.
