Just got a roadie. Trying to get on the road. I'm thinking carbs.
Ok. Sorry this will be long, but you need the whole story.
So I didn't have enough money to buy a nice perfect r*, but I got one that had been sitting for two years for a great deal. He's was in south Carolina, I'm in north. Average temps are extremely close, he might be slightly higher elevation, but can't be by much. (This is for later)
So when I got it I started tearing it down. When I opened the carbs they were green and really bad inside. See pics. So I got all the goodies to rebuild her minus the actual carb housing and other parts that survived. Cleaned the whole system. Was really sad that such a beauty was allowed to get this bad. But he always thought he'd get back on one day.
So I did the rebuild. I'm not a mechanic but I got skills. I got that thing beautiful. Used needles and pipe cleaners, soaking and replacing until everything was free flowing again.
New the reason I mentioned our locations, is this. THIS SUCKER WILL NOT RUN RIGHT! The best I can describe. When I start it cold, the choke has to be OFF. If I choke it, it sounds like I'm choking it. If I let off is smooth. The rmps dip when iadd choke, and increase when I close it. Any throttle, coughs and sputters. Enough throttle, dies.
The jets are oem, ordered from Yamaha dealer. As I mentioned we're low lying in Carolina. The only exhaust mod was the stage 1 holes drilled in cone. Not enough for rejet. I adjusted the float, accelerator pump, pms. Still. The slightest throttle, puhpuhpuh. If I let it warm up for 10 min ir so, throttle is more whup whup puhpuhpuh. If I place my hand over Airbox opening it gets smoother but too close it dies, but still won't accept throttle. There was only one jet I didn't remove because it was acting like it would break. It is at an angle and I didn't like it. But I shot my air compressor through it and it seemed ok.
So in synopsis. The choke acts like it's reversed. It starts and idles ok, but the slightest gas kills it. All the jets are replaced or were accepting air through it. The diaphragm is good. The accelerator pump is good and it sprays good. Float sry best I can. I'm at lower elevation. Only stage 1 mod. Oh and New plugs.
Is there anyone who has any ideas? I'm dying here seeing this in my garage and not being able to ride. This weather is perfect and I'm going down the road in a cage. Smh
If I can add pictures I'll do so.If not maybe I'll add them to my profile.
