Sorry guys, but this is actually my third post on here! I am a little bit out of order.

I'm located in northern IL about 1.5 hrs west of Chicago.

I rode a borrowed bike about 50 miles last year and took the IL safety course.
I purchased my first bike on April 12th 2018.
Since then, I've put about 200-250 miles on my bike.

I'm not a gearhead, but I've turned a few wrenches including (with MUCH help) an engine replacement in a '88 F150.
I grew up with a low carb diet (Fuel Injected cars only), so my knowledge with carburetors is weak at best.
I'm an electrical engineer by trade.
I build electric guitar amplifiers as a side job.

I came here to research the bike I was planning on buying (and now have purchased).
A 1989 Vulcan 750 with ~18k miles on the clock.
I'm impressed with the bike so far, but I'm interested to see how far I can take it.
It's a respectable 2nd place finisher to my friend's V-Rod.
I don't expect to beat it, but I'd like to be able to make out his license plate in a 1/4 mile.

Welcome to the forums! Not a whole lotta performance to be squeezed outta these bikes, Kawasaki did a pretty good job of getting every last drop out of the little 750cc engine. Maybe some carb tuining (needle washers, idle mix screws) and setting the clearance on the pickup coils might help a bit, but nothing much is gonna match that V-Rod considering it has nearly double the HP and torque, but you can probably out-corner him!

Let's not forget an order of magnitude greater price

I just figured there's an extra horse or two locked behind factory emissions based tuning. Has anyone dyno'd a bike after an ear shave or a coil gap mod? Or is it all butt dyno measurements?


'89 VN750 Bought stock 4/12/18 @ 17805.9 miles $800. Wrecked once. 27454.5+ miles

Completed modifications:
Removed mufflers, straight pipes out of GB. 110/90 Front Tire. Pick-up coil mod. Shindengen MOSFET FH020AA r/r. USB Outlet + Voltmeter. Repainted Metallic Blue w/ new tank bages. Ear Shave (wo/ coasters) 40/140 NO shims 45MPG. MCCT conversion.

Planned modifications:
Custom LED turn signals. Windshield. Highway Pegs. (Possible) ignition adv. Tuxedo Mod. Ignition coil mod.

Goats belly

I took off the goats belly, it is underneath your battery, added brand new Harley take off mufflers and removed the smog and plugged the reed valves with vacuum plugs and I noticed a performance gain. But others argue you don't gain and might lose power doing this, but at least your bike will sound as good or better than his

FYI :
Kawasaki introduced the 750 cc class Vulcan worldwide in 1985. Due to tariff restrictions in the United States on bikes over 700 cc imported from Japan, the initial US spec model was limited to 699 cc. The tariff was lifted in 1986 and the Vulcan went to 749cc.
