Nineteen looks like a exhaust stud . I would just use a head bolt that located close to the spark plug . Or get a oil temp gauge from XRs only ?

Looking at this pic again, I remember there is a bolt right in front of where the spark plug goes and it is a 10 mm washer. I think that might be the ticket to try.

Any concerns with that option?

So there is a leak concern which is also mentioned in the install instructions.
Call TrailTech, tell them what you want to do, and they will hook you up

Maybe I'll do that. I emailed support and the reply back wasn't encouraging...

I've heard that before, but their phone support is excellent.

Got out for a ride on Monday. New tank and Vapor working great. Was nice to ride to the trail, ride and then ride home without gassing again.

I need to calibrate the Vapor better. When it reads 50 mph, I'm actually going 55 to 57.

New XR

I was given an xr250 on permanent loan recently. The owner lowered it with a devol lowering link and I want to take it back to standard height. Any one know the best source of a stock link or have one laying around? The original is long gone.

Anything in particular I should look out for aside from regular maintenance?

Thanks! -Jesse

Jetting frustrations

Alright. I am at my wits end.

A little background:

I have an XR250R carb ( model number is PD 05AAAA1), XRR header (with ground welds) and a Supertrapp muffler (4 disks) on my 1994 XRL. The carb was advertised as an '86 when I bought it, but the pilot jet has the larger thread diameter (5.9mm) so it is from between 1994 and 2004. It is spotless inside. Floats and needle valve are in great condition. I just checked the float height and it is right at 14mm. No intake or exhaust leaks. It has a unifilter and I have not yet removed the snorkel.

I've been chasing what I think is a lean condition at idle. The RPMs won't come down to idle consistently but hang and hunt around. I have gone from the 40 pilot that the carb came with up through a 42, a 45, and now have a 48 installed. Things are getting better, but still not right even at 2 turns out on the fuel screw. All signs point to trying an even larger pilot, but I haven't heard of anyone using such a big one on the old-style, wet sump bikes. Is there anything else that could be wrong?

Any advise would be greatly appreciated. I want to ride!
Thanks!

Faulty o-ring on the air/fuel mixture screw?

Sadly no. I sprayed the entire carb and associated bits with starting fluid this weekend while the bike was running. No change in rpm.

I then reduced the number of Supertrapp disks to only 2, which should have sorted out any exhaust-related lean condition. No difference.

I am beginning to think that the carb is faulty in some way. Going to install my old carb with the larger jets to see if there is any improvement.

Feel free to chime in if I'm missing something here.

Thanks

Hard Starting by Kickstarter

Long time lurker and finally need some information.

I have an 86 XR250R with Baja kit that I can't kick start anymore. It will bump start within a short distance. I have disassembled the carb and blew out all holes that I can see and cleaned all the crud out.

Should I go ahead and put it in carb cleaner before I put it back on the bike?

If I do put it in carb cleaner are there any rubber pieces hidden that might be affected by the cleaner?

Thanks in advance.
