New bike, fuel consumption? surging?

Hi Everyone: New guy, with New 07 VFR. Got a couple of questions. I picked up my bike from the dealer last week. It seems like it uses a lot of gas? I'm guessing I'm getting about 35 mpg, is this normal? Bear in mind it's a new bike and I'm breaking it in so not really going like hell on it. A couple of times up to 100 or so but going pretty easy.

Secondly, I was clipping along about 120 today, and I thought I felt the engine kind of surging. I was nowhere near full throttle. It could have been the road, but I really don't think so. Is there an efi problem with this model?

Cheers
John.

 

What do you mean by surge? My intitial thought is that you're feeling the VTECH engage. What kind of RPM's were you at when it happened?

As far as MPG you should be right around the 45mpg range(give or take 5mpg) depending on how you ride.

 

Still breaking it in,?how many miles,120mph,?I did it too.600miles and an oilchange,check oil,then twist that thang.My '04 surges 4500to4900rpm.Your V-tec hits @7000rpm,big surge there.jet,the site takes it from here...hang on,bro'.

 

if your rpm hits 8000, the vtec kicks in creating that surging feeling.

 

My '04 v-tec goes @7000rpm,I believe it went to 7500 in '06.Riding twisties for me goes into the higher rpms anyway.Zing,turn, turn, turn!

 

07 VTEC kicks in at 6800 and of at 6400 (If i remember correctly from the book)

 

No, it's not the vtec kicking in, I was over 7k rpm. It was like it was speeding up and slowing down a little just slightly, like a feeling you would get in a gusty head wind, but there was no wind.

One of the other replies talked about fuel consumption: I was just asking. I filled it for the first time the other day, and put in about 2.5 gallons, but I only had 70 miles on it and had been riding conservatively. However, they may have not completely filled it at the dealership too. I did notice that the first couple of bars on the gauge drop pretty quickly.

 

Yep, I've only got a hundred miles or so on it. According to the book as long as you don't do full throttle starts and hit the red line you are ok. I've just pulled it up to 100 or 120 a couple of times in short bursts, just up for a few seconds and then back down. I got a great deal on the bike. It was in a crate and they kind of lost it in the warehouse. When they realized it was there a few weeks ago, they decided to discount it heavily and I happened along, lucky me. I had an SV1000S two bikes ago. I think it had more muscle than the VFR, but then again it was lighter and had about 15 more horsepower.

 

My 07 gets around 35MPG (or even a bit less) with a mix of driving that's a bit heavy on city and short trips. If I run a tank through at normal highway speeds (such as on a trip) it goes up quite a little. The best I've gotten so far is around 44MPG.

 

I rode it for about 186 miles today and the fuel tank level is about where I think it should be. I'm guessing it's going to get around 35-40 or there abouts. I just don't think it got filled all the way up at the dealership. I really like this bike! Handles great. Not as much sting as my SV1000S, but then again it's almost 100 lbs heavier, and has about 12 hp less. I have also been going easy on it, so not building the revs on it like I should. A very nice bike indeed.
Cheers

My 04 with 38,500 miles, and gutted exhaust gets around 42 in town, and 50mpg on freeway trips! I usually cruise between 5-6K on the freeway. Only time I have experienced a surge would be around 7K when the V-tec kicks in.

 

Glad you like it John.

 

I think I figured out the surging problem. I was looking the bike over last weekend and noticed that the chain was too tight. I guess they didn't set it up too well at the dealership. I loosened it off, and I'm sure that will make a big difference.

I've got 2003 VFR and I use 32.81/gal when I ride average 3000-4000 rpm (no VTEC at all). It goes down to 29 miles/gal if I do average 5000-6000 rpm and freequently venture into VTEC.

I read somewhere that 06 model should do average 43.5 miles/gal???? Not sure if that is possible...

Does everyone know if there is something one can do to reduce fuel consumption?

Thanks

 

I wanted to add this post here...

I have been having problems with my VTEC kicking in at 6800RPM's. I just wasn't feeling the surge or hearing it. I decided to take it to the Honda dealer that I bought it from and they told me that the bike (03 VFR) has to be at a certain temp before the VTEC kicks in and that it is metered by oil pressure. I understand this. Just recently (as in today) my bike started surging whenever I held down a steady RPM. It doesn't matter what RPM it still surges in every gear. Also, above 6500RPM the VTEC sounds very weak and miss fired almost. I don't know what exactly to make of it but I'm taking it in tomorrow again and we shall see.

 

Im interested in this issue, I dont feel like im having any vtec problems really...but this bike surges for sure. If your steady accelerating it surges just like if you couldn't hold the throttal steady, almost on and off like it cant hold a steady rpm. Im wondering if at this point if this thing needs a little uncorking(exhuast). Maybe the muffs are restrictive? Anyone got feedback on this?

 

My initial thought was a mud dauber (wasps). I thought since I keep my bike in a storage facility that maybe a wasp could have made a home in my bike somewhere. This may be very far fetched but I don't know. However this theory doesn't explain my VTEC problems.

 

I rode my 2002 today for the first time ever since buying it, I noticed the same surging feeling in it. I also noticed that especially in first gear, unsure of the RPM's , it goes good threw the revs but feels like it hits a flat spot or something and loses power I think. My guess is its somewhere around 7000 rpm but not sure. It definately was not feeling like a power surge at all like a vtec power...but again ive never riden a vfr till today and it just seemed a bit doggish in my opinion. The bike has one previous owner, well maintained with 5k mikles on it when I bought this year. Chain is a bit tight I noticed but I cant imagine that would create that issue. And its 100% stock equipment. Any thoughts? MAybe the vtech is messed up or something?

 

It's possible you have an issue with the FI mapping; getting this fuel injection thing correct across a wide rpm range is difficult. Some bikes seem to have more of an issue than others. BTW, once it's warmed up my carbed '02 Magna V4 runs smoother than my fuel injected '04 VFR ; still hard to beat a well-synched carb (4 in this case).

Im going to put some remus cans on mine and see if that improves things a little. Going to order them monday from sport tour.
