All I Can Say IS W O W !!!!!!

Had my first chance to ride since getting the problems straightened out.

With the new pipes, the ear shave, and the jetting, it is amazing how much more jump the bike has. I crack the throttle and the bike wants to jump out from under me. Amazing.

Still some tweaking to do.

Slight stumble cruising at part throttle, need to go back and check carb sync, mixture screws, and perhaps one more notch on the needles(little more fuel).

But this thing is much quicker than stock and so much more fun now!!!!!

Pipes sound like a big twin, fairly quiet part throttle or crusing, nice and loud when you get into it.

More tweaks tomorrow, a good cleaning, and I will put up some pictures.

It is a night and day difference.

Its always fun when a big project gets finished (or almost) and it works out so well. 3 weeks ago my engine was on top of the Workmate and there were parts all over the garage.

Nows there's just a bike there that runs great.

Congrats, Jon, sounds like you are now qualified to be a certified Vulcan mechanic.... I'm wondering if the pipes/jetting made the biggest diff. in the performance, and how much everyone thinks the ear shave helps? Thx for any opinions here.

ear shave wont give much if any boost on performance (just faster throttle response cause a shorter intake), but the big gain here is in the jetting, and possiably in the pipes. u said u have a set of MAC's? right. our engines typically are already on the lean side, so with the rejet, you might have picked up a full 2-5 hp. which on a bike that weights in at 500 someodd lbs, that is rather significant. I dont have any information on the pipes though as to if there is any gain there, but typically with aftermarket pipes, low rpms drags, but high rpms rock compared to stock.

Glad you got it all done and its running great congrats!!! can you do me a favor once u get some decent riding in and tell me the diff in your fuel mileage with the new jets? i use mine as a commuter, and if its a loss of 1-3 mpgs for the boost in power, i'll take it!

Jon,

Glad to here to mods that you did made such a big difference. I am just waiting on some $$$ to do the ear shave, rejet, and degoat on mine. I am hoping that I am happy with my bike as you are with your when I'm done.

Jon, with the rejetting, are you still noticing a power lag in low rpms, or did that take care of it? After my degoating experience and the macs, I'm not inclined to go that route again; but if changing the jets helps, I may reconsider.

Cindy -

This thing makes way more power all across the rpm range. I used to forget about passing on the interstate going 75mph as I knew it would be a slow process. Now, twist throttle, up to 85 - 90 in a flash.

Low end is much, much better than when it was just degoated. I felt the loss so badly after degoating that I was going to regoat.

I can't say for sure how much is re-jetting helping the pipes (degoat), or how much re-jetting & the ear shave is helping.

I am going to add one more shim as it has a slight stumble, hesitation while cruising at part throttle. That will be 4 shims under each needle.

Saturday I was getting on the interstate via a 2 lane on ramp. I felt like seeing what it would do and passed an Infinity that did not want me to before the end of the ramp (about 90 mph). This would have never happened before.

I think as others have said (Hizzo for one) that the stock jetting is just too lean. Probably related to EPA and gas mileage concerns.

Get your carbs straightened out?

Jon
