Maybe this should be in tech but I figure it will not take long here... What Year? I tried google pics and it looked like a mid to late 80's? I have not seen it yet... the guy "doesn't know..."
I'd guess 83-86. I had an 83 XR-500R and they were very similar. Rear fender has been replaced, tool bag missing. Front brake cover not original.
Looks like an 85. I think the fork protectors were blue in 85. The XR on the seat looks like 85 as well and if it's the same as other Honda products, I believe they put the blue on the swingarm in 85 too.
didn't the '85 model have dual carbs? I know the XR200 did....buddy had one and it was a great bike. Later reports said Honda had problems keeping them synched, so in '86 they went back to the single carb.... But yea, I would venture to say, mid 80's....
And I changed the wrong number when I edited my first post. The XR on the seat was 1984-1985, NOT 1985-1986.
I had a 87' XR250r they are bullet proof bikes that does looks like a 84 or 85 thumpertalk.com for more info
is the frame red or orange? red changed to orange in '84 I think. dual carbs make alot more power/heat. jetting can be tricky. factory jetting is way too lean. they can get a cracked head between the exhaust valve guide and sparkplug hole from excessive heat. the factory air box/boots make removing the carbs a pain, I removed the boots and use uni filters, also use 350R carbs on my 250R, and an O2 sensor and mixture indicator, if the bowls dont have the easy main jet access you can get them from the XR500, direct swap. /////
That's an 84-85. It's not synching like you do on a carbureted four-cylinder road bike - the carbs act like a two-barrel setup. One is used at partial throttle openings, then the other opens. There is a tang that initiates the opening of the secondary. It usually is set to open it too late and you have hesitation. Just bend the metal tang to initiate the opening earlier, and you will eliminate the bog. I've owned three '84 XR500s, and it's really an easy fix. These are excellent bikes. The weak link is forks, it's really front-end heavy and they're too softly valved (and sprung). Find a set of '87 CR forks, it turns it into a sweet off-road machine.
Is the dual carb thang on these the same as the one that came on the XL600R's of the same years? That is to say...does only one of them have a float bowl, and they engage sequentially? If so, the trick is to bag the whole sequential thing, and make it so that they both open and close together, right from idle...then jet the main one w. the float bowl ignoring the other one. I wish I could remember what it was I did to join them...modded the linkage somehow. EDIT: ya, you have to bend that little tab...thanks for the reminder! Anyway, it worked perfect on 2 bikes...both would pull from about 4 RPM, and were nearly impossible to stall. Hope that helps.
