XCR 700 Diagnoses FINALLY

Finally figuring out what the root cause of poor drivability. Took a few trips back and forth from the shop to the lake to find the smoking gun. Whomever I purchased the carbs from had robbed the XCR 700 needles out of the carbs and replaced them with XC 800 twin needles.

Nice looking sled. Glad you got it fixed. Love my 600 xcsp.

Take the tank off run new line and the fuel filter in the tank. How are the o rings in the carbs? and possibly the floats.
It’s a really nice sled.
Where I am in Canada this has been the best winter we’ve had is more years than I can remember. Nice cold temps everyday. Lots of snow. It’s usually the weather you’re describing. Cold snowing the hot and raining, but this year has been great.

XCR 800 had rich issues on some units,mid range in trail or in heavy load conditions would start pukingand dropping needle would cure it

@@JohnHartley-h7y I diagnosed the issue in the video, it had the wrong needles

[@larrywarner9314]

Try using a different set of carbs to see if it's the carbs or if you have a different issue.

[@sneeky_peet]

@@larrywarner9314 i did in this video. And solved the issue

[@JohnHartley-h7y]

It’s probably rich. Try dropping needles one groove.

[@sneeky_peet]

@@JohnHartley-h7y I diagnosed it in the video. It had the wrong needle in it

[@JohnHartley-h7y]

Those plugs were scary. Lol

[@sneeky_peet]

@@JohnHartley-h7y Tell me about it, had me freaking out!

[@ryanxcr800]

Check fuel tank gas line make sure not rotted if your finding debris in the carb. Will cause many issues

Did you do a vacuum pressure test when you built the engine ?

Drain wut fuel your using, and put three gallons of mixed fuel at 40:1 !!

[@sneeky_peet]

@@larrywarner9314 I diagnosed it in the video, it had the wrong needles in it. The first 5 gallons were mixed 40:1 also. Fresh engine is a must
