Carb tuning

Recommended Posts

I've got the 650 Spider, the one with the two cylinder engine and side draft carb. The right plug was cold/not firing, so I changed the plugs out (thanks Silverbullet for the plug type, and this forum for how to do it) and then tackled the intake. When I pulled the air filter tube off, there was standing gas in the carb inlet. Because of what I found, I took off the carb top, cleaned the needle and seat, although they looked fine, and put it back together. I started it up and it ran great. BUT.... if i wanted to change the needle and seat, say to a Viton setup vs. the solid needle, where would I look? Do any Japanese bikes or quads fit? I found the oil filter is the same threads as my 91 Nissan 2.4L pickup, so other parts might cross as well. One issue i can see is that carbs have not been used on cars in the US since about 86.

      We recently purchased the Axis x550. Fueled it with 93 fuel and drove one time around the farm and the 02 fault error appeared. Any ideas?

      I have a 2017 Intimidator XD4 800cc 4x4.  It will run great and then it's like it goes into safe mode and only runs on 1 cylinder.  It's not fouling out the plug when it happens.  Some times when I stop and restart it, it works fine.  First I thought it was a spark issue, then a fuel issue, but I feel like it's a short in the wiring some place.

      I swapped out the Subaru motor for a Predator 670cc. If I remove the heat shield around the muffler, The stock muffler sits in there just fine with 1" to spare.
      Only problem is the exhaust exit is toward the back seat instead of out the back.
      Do you all think that the stock exhaust would be okay (just as effective) if cut a hole and welded a pipe on the reversed (opposite) end? Of course, plug the old exit end. Other option I thought of was to roll a tube 180° with a 7" center line radius and finish extention of 12" or so.
      Any thoughts?

      Can anyone tell me how to get the engine codes to display on a 2012 Bennche Bighorn 700X?  I played with the gauges once and lucked up on this but can't remember what I did.  Will the codes automatically display if there is a code or do you have to cycle through the display?
