Hey all, I have just bought a 99 Vulcan 750 that a guy has done some work to the bike. When I bought it I didn't know that it couldn't go past 80. It's sitting at 80 in the firth gear. He rejetted the carbs to give it more power, do you think that would be why it's only able to get to 80? I'm totally lost at why it's like this. Any help would be greatly appreciated! Thanks
Lots'a guys w/ more jetting experience here. I'm running a completely stock system. I've got original airboxes, filters, carbs, jets, exhaust, goat's belly--everything. Mine'll do better than 80, so if getting more power was the goal previous owner fell short! Stock system will pull hard all the way up to red-line. Fourth gear will get you to a higher speed faster!
To get help, you're going to have to say whether you're running stock exhaust, air filters, etc. Have you pulled the carbs? Do you know what size jets you've got? I can't help you with that, but somebody here will know what size you need.
These bikes can do an honest 110 mph. Sounds like the PO screwed up the bike.
Make sure the carb vent line is placed right, and make sure both cylinders are firing.
Then check what jets are in the bike.
Hey all thanks for the replies. It has shaved ears with k&n air filters. I've checked the vent lines and they are fine. I'm not sure what size jets are in there but I'm thinking of going back to stock if some one could let me know what size they are. I'll also try the choke to see if that helps out any.
