Noob here. I apologize if this has been discussed somewhere else but I couldn't find anything. I recently acquired an '89 VR that's been triked. Old barn find with only 81,000 miles! Plugs, fluids and lots of TLC and it's running now but still needs the carbs synced. I've determined that the speedo is fast by 5 - 7 mph at road speed, but from reading the forum posts, that sounds pretty normal. I'm not sure the diff ratio is proper. What speed should I be showing at 4000 rpm? It's indicating around 63-65 which is actually a bit shy of 60. That's comfortable but can get you run over in traffic!
The fuel mileage has been awful but is improving with a couple of cans of Seafoam and about 500 miles under the tires. Last fill-up, I got right at 30 mpg. Still idling at 1200-1300 after it warms up. That seems high to me.
Any ideas and suggestions will be greatly appreciated.
