I know there's gobs of threads out there along these lines, just hoping to narrow this down some & dig less. I live at 7,500 ft and for the most part do not ride any lower. Can't get carb dialed in. Ran it hot, ran it lean, ran it rich, I finally get it where it feels right & will get riding for about 10-15 mins and it cuts outs, engine dies on descent. After it dies the MF'er wont kick over for at least 20 mins. Gone back and forth all over with the idle get same result. I think my issues are from the hot start adjustment. Can someone with some carb experience on these 4strokes just tell me about what should be the right adjustments (turns out), at high daltitude: - fuel/air mixture knob (bottom of carb) - idle adjustment - hot start adjustment - Is the knob adjustment for the hot start (where it goes into the carb) & the cable adjustment (cable adjustment for hot start up by perch) the same adjustment? I get truly dialing it in takes going off RPM's, I am just trying to figure and know I am in the right ballpark so I can rule shit out. Input is much appreciated have been grounded for 3 weekends in a row now &%$#@!ing with bike. About to go mess with it a little more and if I don't get anywhere will get a picture of the plug up. Thanks,
So let me start by introducing myself, I'm shifty00 (I would tell you my real name but I don't trust the interwebs haha) am new to this forum. I am a welder/fabricator and I have decided to build something fun as a project. I got a Yamaha Warrior 350 for building my buddy a rack for his RZR. This thing was beat but it was free so whatever. Anyhow I went to drain the oil and found about 30lbs of magical pixy dust on the oil filter. I did manage to get it running but it was spewing smoke and didn't enjoy starting. long story short I decided it would be more fun to make a hybrid rather than dumping money into an already "Meh" engine. That leads me too my purchase of a 1993 XR600R engine on Craigslist. I looked it over, some things are missing but all and all it looks ok, it came with a carb and at the time I was skeptical about the carb because it just looked too damn busy for an xr motor. And now after knowing what that OEM carb looks like I know this is not at all an XR carb. It has features I wouldn't mind but I have no clue what it is or if it would even work on the motor. It is a CV and a pumper and has remote choke (dose not stay engaged, feels like a spring pulls it back closed?) Anyhow can someone please tell me what the heck it is... I can't find a single damn marking on it, so I assume its some china crap but I really don't know. here is a link the previous engine owner gave me after I txted him asking what the hell carb he gave me.... http://www.ebay.com/itm/262774188434 Also can anyone tell me if I will have oil starvation issues if it tilt the motor at a sharper angle than it would sit in the dirtbike frame? I figured dry sump would be very forgiving in that area but I worry about oil pooling to the front of the head and stuff like that. I will have about 1,000,000 questions but lets start here haha. Here is a pic of the infant stage of the build. (engine is just resting in there no mounts made yet). Thanks for any help with my Yamda/Honaha YFM600R...
