So I just installed Sean's Muscle Kit and I LOVE it! Unfortunately, I feel as if the fumes from the bike are a bit strong. I asked Sean already about it but I'm just curious if other Max owners have the same issue. If I sit at a traffic light, the fumes are pretty strong. People behind me say that I smoke them out. Hard acceleration does not produce any cloud. The exhaust tip is not wet. After a ride, my clothes smell like I have been riding a two-stroke. The smell in the garage will linger for days. Below is a run-down of my setup:
1997 Yamaha V-Max 1200
Morley Muscle kit installed
- 155 mains
- 177.5 PAJ2
- 90 (whatever comes stock) PAJ1
- stock pilots
Stage 7 needles, 3rd clip from blunt end
UFO Dragstar 4-1
V-Boost always on (unplugged in open position)
A/F screws at 3.25
Slides drilled, Stage 7 springs
The bike runs like a raped ape, way better than before. Not sure if it's just the V-Boost that's giving me that sensation or truly its running better. Eventually I will get the bike to a dyno, but I would like to tune it close so that I don't have to spend too much (much more parts I would like to buy). Will also be checking the plugs shortly after I can romp on it and shut off. Just gotta watch for cops! (would look bad since I am one lol). Haven't fouled any plugs yet...
On startup, I have to run 1/4-1/2 choke to keep the bike running. Once up to temp, it idles at 1000 pretty good. Possibly a little on the lopey side (this is probably b/c the V-boost being always on). The carbs are synced. Before the jet kit, the thing would start almost always w/o a choke. So this seems odd, but a few users say that even a well-tuned Max runs terrible until the temp is off the stopper. Until it is fully warm, even a small blip of the throttle causes the bike to bog and an air sound comes from the carbs. Then idle returns to normal.
Riding is a blast. It pulls strong in all gears (I think). If riding normally/cruising, I do have to keep the bike out of the final gear b/c it sputters until there is a load on it. Not sure if this is regular or not. Before I could cruise at 45 in 5th gear, no issues.
I've tried leaning out the A/F screws but my vacuum drops on the synch tool (cheap Motion Pro) and then I have to adjust my idle thumb screw. Then the bike hesitates (with the whooshing sound) from the carbs on throttle movement. I fear that if I richen the A/F screws, the smell will get worse. Also, my right front A/F screw leaks a bit. I just can't believe that would be causing all the smell. Just purchased a new one from Yamaha, will be installing today or tomorrow. Unfortunately I gotta work the next few days which land on the two nicest days of the week for Ohio! Bummer!
Is the smell a common thing? There is a lot of questions b/c I only found one previous topic about the smell and that was on a CA emissions bike. Any help would be appreciated!
