    I wonder if there is anyone who can give me some advice please. I have just completed fitting a new Leo Vance System to my VFR. The model is a 2005 interceptor.

    In the instruction pamphlet it made mention of a graphite gasket that fits between the header pipe and the slip-ons. Now there was no gasket in the packaging and they mentioned that one should not re-use the graphite gasket. Is it ok to ride without this gasket ? The system does not seem to have any air leaks at all. I have just let the bike idle for a few minutes and given it a small rev to say 5000rpm.

    Secondly is it necessary to have the engine management system re-mapped ? Will the bike run to rich/lean because of this system. I have removed the baffles already.

    Last one, i have tightened up all the bolt and only needed to use 1 spacer in the packaging but the right silencer seems to still have a little movement in it. Is this normal ?

    Please if someone can give me honest good advice as i would hate to burn a hole in a piston etc. I am doing a track day with it on sunday and also wanting to do a longish ride tomorrow on it.

    Thanks,

    Neville Puttergill

    Great choice on exhaust!!! You will love it I'm sure. Don't worry about the gasket, its not necessary and I went through the same thing in my install. It was a little frustrating translating the instructions! Those straps that hold the cans are torture if the rubber comes off before you put the cans in place. I have a fender eliminator too and my pipes are pretty much right up against the plate but it is ok.
    As far as mapping.... I have a power commander and I put it on the 1 map. I also have my o2 sensor blocks installed so my bike runs a little richer already. If your baffles are out you may run a little lean but the bike seems to compensate. Its probably a good idea to get a power commander just to tune the throttle response. Thats the best mod I have made.
    What type of movement are you getting? My pipes are pretty solidly mounted. Theres a little give because everything is together with spring pressure but it isn't loose enough to rattle. I have adjusted my cans here and there, its tough to keep them perfectly aligned with all of those pieces! Remember to check the bolts where the system bolts onto the cat and your top mounts on the cans after the first few rides..... Good luck!!

    Thank you Alter Ego,

    I feel alot better knowing that i was not a fool on the intallation side of things. Yes, i did battle getting the cans aligned, but got them pretty close eventually, like almost 3 hours later for the complete install. I am waiting for my tail tidy, only arriving in 4 weeks time but am busy doing my own makeshift one in the mean time, the plastic rear looks terrible.

    One more thing, i have been to a few track days and the guys there keep telling me that i must drop my tyre pressures. I am running it according to the book at the mo, about 2.5kpa (front) and 2.9kpa (rear) with Bridge stone's BT010 (front) and a BT020 (rear) combo. What typical pressure are you running ?

    Also does the Power Commander and O2 sensor take away the "powerband" at 7000rpm. I have noticed under pretty hard aceleration when i hit it into 2nd gear the front lifts off the ground unintentially, and i have to back off the gas to get her stable again.

    I have also got an off-road quad (LTZ400 Modified) and have had off-road bikes but am still battling to get to grips with how far i can lean into corners, need to trust my ruber a lil more. Been i bit intimidated as quite a number of the guys i ride with have Suzuki GSXR1000's and they give it horns all the time, cant keep up with them, specially in corners. I have managed a odo reading of 238km/h so far and run out of road, they reach just under the 300km/h mark.

    Thanks for the advise.

    Lifes a journey, enjoy the ride...

    Neville

    Hey I just got a 2005 in sliver and I'm looking at the Leo’s and power commander also. Where can you get the 02 sensor eliminators? Did you notice a difference with the pipes and the commander? I also have a Hot Rodded 2005 LTZ bored out to 455...She rips!!

    pipecity.com is where I got my Lasers, PCIII, and filter. I too need the O2 sensor eliminators. They have them.

    Ditto on what AlterEgo says about the LV install. I have to adjust the cans after longer rides to even them out again. I didn't have any issues with not installing the mystery gasket either and I've had mine on the bike for almost a year now.

    As for the Power Commander (a future mod for me) I understand you can almost eliminate the off idle jumpiness with the Elim/O2 elim combo. For the best results you'd have to take the bike to the dyno for fine tuning. Some have run the Commander with stock settings with good results but without a custom map you're not using the Commander to its full potential. Don't forget the PAIR block off plates!!!

    The VTECH roll on at 7000 only gets better with the PCIII! :vtr2:

    SILVER IS THE FASTEST COLOR!!!:biggrin:

    The PCIII will help smooth that out but may not be exactly what you're looking for.

    You might want to try going down one tooth on your front sprocket. This will remove some of your very top end power and put back into the midrange. The bike should start to progressivly build more power than stock at roughly 4000rpm, it does a great job of smoothing out that VTECH transition at 7000rpm.

    Best of luck!

    P.s. to Silversurfer, Yea bro, the PCIII completely elimanates that parking lot speed jumpiness!
    Highly recommended. I nearly failed my licensing road test without it.

    Man I can't find the carbon pipe's anywhere? I need the pipes and the 02 elims. I went on pipecity.com and they just have the aluminums....

    Hey man, just wanted to give a shout out. I used to live in Orange! I helped open the Home Depot back in '92. How's everything going out there?

    I just looked at leovinceusa.com and they've got what you're looking for @ $970. Sure if you goto ebay you could find some discount dealers aswell as some used.

    Check with another user on this site kia001, he has his own business and sells the LV Carbon for way less than buying it direct. Check with him for pricing.


    A few people have purchased from him on this site (like ME! :biggrin:). Painless process and quick shipping.

    Id suggest trying Michelin Pilot Powers on your next tire change, especially if youre doing track days

    SomeFun- did you get the standard tips on the LV's or the conical ends? I'm close to ordering a set of the CF and thinking the new conical ends would look trick..
    Also, has anyone fitted the LV Ovals include the stock hardbags/brackets? I recall seeing them together somewhere..
    PS - Silversurfer, your link for the online source for the LVs is active now..

    I had the standard tips any they looked great!! You'll love the sound. I also used them with the hard bags and there were no issues.
