Hey guys. I own a 2004 Intruder 1400, got a jet kit, k&n filters and pipes. It was a noticeable seat in the pants upgrade in power and was pretty content with it. This last fall I went riding with a group of friends, one of which had a 1988 VS 1400. I figured Id have no problem keeping up with him... I was wrong. He could consistently pull away from me every time. We bang through the gears from a red light, roll on the throttle at speed and ran them up to 90mph... every situation ended up with me reading his license plate. Curious to see if it was just rider error or somthin we swapped bikes for an hour or so to see what would happen. Right off the get go I felt a big difference. I beat him in every situation and was even able to pull a bike length or two further from him than he did to me. My only real problem I had with this thing is I was constantly trying to click a 5th gear that didn't exist which I eventually got used to. This was a STOCK 1400 with 14K on the ticker. Why on earth is it faster than a newer model with less miles and some performance upgrades? He ran the 1/4 mile at 12.71@ 98.3mph and keeps the slip in his bags to prove it... after riding it I can believe it. I've talked to everyone and keep getting the same answer that suzuki de-tuned these bikes via the camshaft?.... If so is it possible to put a pre- 1990 model cam in my 2004? Or are they really all the same and this guys bike just built on a Wednesday?

The 1987's and 88's have about 10 more ponies then the later models.
I'm not sure why.
I love my kickass '88.

The 4 spds were always quicker than the 5's.
Most likely the gearing differences create more torque.

I think my bike is rated at 60h stock. I'd guess I got 65 or so with my parts now. What did the original 1400's push?

You have the EPA to thank - they forced bike emissions
Years later they forced them even more (hence lean mix from factory)
EPA even made them put in that brass plug (so you couldn't do what you did)
2010 summer:: 12,000 miles, 60 days, 23 states, camping and cooking ride from Ocean City Maryland via US-50 to San Francisco, CA-1 up the coast, loop around BC, and US-2 back along the top of the country to home in DC --- was absolutely wonderful - no problems - great IAers met along the way.

Is that 71hp factory or uncorked?

Yea the EPA has their hands in everything  ... Garden tractors even have cat. converters on them now...something else to plug up... is that really needed?.... Anyhow.... I was talking to a guy at the parts store who worked for a suzuki dealer around 15 years and remembers the first 1400 they got in. As time went on he said "something drastic was done". He mentioned the carb tuning being a maybe but said that the power the 1400 lost could of been a mechanical change, possibly being the cams since a different head and valve design would have probably changed the 9.3:1 compression ratio and that has always been the same. The other possibility he's heard in the past was an ignition timing change which could also be a play a role. I cant find and info on either of these so I'm still a little lost here. I just want to "correct" whatever was done at the factory so it can run like it should. I've seen the Dyna 3000 boxes but what gains can I expect if any?.... And better yet does a performance cam exist? Edited by Strick219 on Feb 13, 2012 at 12:43 AM

Well..... the cams never changed. same part #'s are listed in all the years on a few websites.... Web camshafts might have some options so I'll have to check them out... that aside, all that's left as far as the old versus the new is the ignition curve... will that alone really make this thing a high 12second bike in the 1/4 mile?

Where  can I find a review of a dragrace from the 87/88 Intruder where they did the 1/4 mile in the 12 second ranche? I did see it here on IA a several times some guys talking about it , but never saw it in a test or comparison.

71 Hp is Factory, so uncorked it ,,could be" more, only if done the job right.
My (sold)uncorked 1992 Truder did have a much higher topspeed (130 mls on dyno) as my 1987 factory intruder.
I do not mis that higher topspeed now( I'm getting older too) and I do love the power this old 87 bike can deliver in factory condition. It is very fast from 0--- 100 mls/hr

Yep, the early ones were more powerfull and quite a bit faster in the 1/4 mile.
I owned an 87 and while satisfied with the 99, it isn't as good a bike as the original.
Not as much power, lower quality of paint and chrome, and not as much fun.
Anyone with an 87 or 88, take care of it, they are by far better than the newer ones.
http://www.motorcyclecruiser.com/roadtests/suzuki_intruder_1400/viewall.html
Although early Intruder 1400s laid down quarter-mile performances in the high 12-second bracket with terminal speeds around 100 mph, our '96 machine turned in a best of just 13.71 seconds with a terminal speed of 93.2. We assumed that Suzuki had fitted calmer cams or made some other change along the way. This bike was just fractionally swifter at 13.64 seconds and 94.7 mph.

When I bought my 87 the dealer had specs showing it as having 72 hp. This website shows the 87 as having 71 and my 99 as having only 60. 11 hp is a huge difference.
Along with the difference in hp there is a loss of over 5 lbft of torque from 82.6 - 77.4.

Hi Woodburyhl,
I did read that article from motorcyclecruiser.com years ago. but what I would like to see the article with the test from that 87 bike with that very fast dragtime from 12 + sec.

I don't know if they have archived things that are pushing 25 years old. I do remember that in the late 80's and early 90's the 1400 was always the most powerfull of all the cruisers. It never lost a high gear roll on.
I know that my 87 was much faster than my 99 is, even when the 87 had over 150K on it.
having owned both the 87 and the 99 I have been able to make a pretty good long term comparrison. The 87 was a MUCH better bike.

So if carb jetting and epa crap is the only difference then if an early model and later model are both uncorked they should be identical. Right ???

Wrong.
Both bikes uncorked wil make the 87 also faster and the difference in power between both bikes wil be the same.

Based on what?? Ive heard this discussion over and over.everyone agrees its the same engine,same carbs, Same gearing in 1st 2nd and 3rd. Only difference there could be is jetting and an uncork would put them on even ground.
Please explain why they are different then,beyond simply saying "Wrong" .

From "Motorcycle Magazine", a 1987 review gave the following from their dyno and track test...
88.2 ft/lbs of torque at 3000 rpm
Claimed 72 hp but actual 58.3 hp at the rear tire
Best run came in at 13.6 seconds with a terminal speed of 99.3 mph
The Suzuki Intruder VS1400 is one of the few bikes that looks equally good from both sides.
