No more tuning CB1100??

[gretle_2.0]

He may have already been approached by the EPA and they haven't yet.

Or he may not want to take the risk of massive fines.

Update, they called me and told me they can’t flash the ecu and I would have to get a PCV

So..... why did Guhl stop tuning but Superbike Unlimited, VCycleNut, Ivan and everybody else still tune/flash ECU's? I'm rather confused....

Does superbike unlimited flash our ecus?

Unfortunately I think you were going to get the same answer once you actually get down to the details with any of the shops.

There is a lot more to tuning an ECU than most people are aware of.

So when you have an uncommon bike, the odds that a shop takes the time to build a file for something they wont sell a lot of is virtually none.

So get a power commander, and yes many shops will tell you they will tune it – but the reality is they are not going to spend the many hours it takes to tune every throttle position at every RPM under load.

Even if they tell you it will be “custom “ it is still just good enough.

Will most people notice the difference?

No, so it comes down to you how good you want it to be.

The cost difference between them tuning the power commander and buying the autotune box and bung welding is probably comparable.

All depends on what you want.

For most people- the generic Dynojet file is probably good enough. You can still manually tweak it yourself without the autotune- but you will be flying by the seat of your pants.

Okay makes sense, so once I have the full exhaust on I just need the stock tune on the PCV and I should be good to drive without being too lean?

It's too bad that Guhl no longer provides the service. I have a 2013 CB1100, and had him work on my ECU seven years ago.

My first change to thew bike was to install the full Yoshimura black exhaust system. I reminded me very much of the Kerker pipes I used to see in the 70's. I didn't bother looking up old pictures to see if that was really the case (Everything looks worse in black & white...). I noticed a little bit of improved performance, but really noticed, and enjoy, the new sound. This exhaust allowed me to retain the center stand, which is a good thing.

My second modification was to send the ECU to Guhl. I was desiring to remove the rev limiter and I thought the cost was quite reasonable. It did just what he advertised.

Next, I installed the Power Commander V. Accidentally wheelied the bike in the parking lot applying the same throttle as before the PC V. so I think the Power Commander did something.

Then I had the bike dyno-tuned. That seemed to create very linear acceleration, with no bumps or stutters. Again, the cost seemed quite fair.

The full package combines to make the bike "different" than the two other stock CBs I have ridden to compare the "improvements" (in my mind). I didn't particularly like the slightly anemic performance of the stock bike. My bike is very enjoyable to me. Just more "entertains" to ride.

But I have decided to sell my CB in the next month. It only has 3,600 miles on it, since I have several other motorcycles to ride, and my passion is adventure riding. It seems that there are a LOT of inattentive drivers trying to kill me on Tacoma's city streets. So I prefer gravel roads and exploration over local rides.

In addition to the modifications above, I also bought the Ohlins rear shocks. I ordered black springs so the bikes inherent classic beauty wouldn't be gobsmacked by bold colors. I also installed the Racetech fork cartridges. And heated grips. And other things I don't recall at the moment. Oh...the Daytona seat which is very comfortable!

It will be interesting to see what those extras equate to in pricing the bike.

In general - modifications /extras on cars or bikes don't really add much, if anything- to a sale. You really have to find the right buyer who wants that stuff enough.

Typically you come out much ahead to take off those parts- put the stock parts back on and sell them separately.

Power commanders are a dime a dozen.. so not much value there, but since the Guhls ECU is no longer made, I am sure someone would buy that..maybe even at a premium over what they used to cost.

Generally, I agree.

But this is the strangest used motorcycle market I've witnessed. Generally, you couldn't give away a CB1100 three years ago. Dealers knew they were extremely slow sellers and didn't want them as trade-ins. So they offered very little for them. Private sellers, after being lowballed by a dealer, put them on Craigslist for correspondingly low prices. And then "negotiated".

Now...low mileage used bikes are a hot commodity.

I'm not going to price the extras as if I should be reimbursed, but my bike is a great value for the right buyer. Very low miles, not a scratch, and recognizable after-market parts that suggest attention to detail...not hooliganism. I figure around $7,500, but I haven't done my number-crunching.

No point in offering the ECU separately. It "might" sell for $300, and it adds so much more than that to the bike with the other mods. As it is, the bike runs perfectly, and with extra acceleration.. I wouldn't do anything to that that might alter it in any way. Unintended consequences and all...

Yeah from all the money I’ve dumped into bikes and cars…you really don’t get the money back from them and I found out I make more if I put it back to stock and sell the parts separate like already said. I just got my 2013 CB1100 2100 miles but bought it from a friend at a good price. Now just looking to buy the rest of the mods like rear shocks, PCV and maybe front springs.

Remember , you do not get money back after you stop playing golf !

[Olyrider]

Who told you that?!

I was counting on all the money I spent playing golf for 60 yrs to keep me comfortable when I stop playing!

If I ever do…
