new to rvf400's and wants more low end

[dr_46]

id like more low end/midrange power....pissing off my neighbours has already be done...the maggot is a slip on so ill keep the can i have now and when i want a quiet little cruise ill slip it on...i want the most out of my bike on the road till eventually i get my bearings and jump to the track so low n mid range would be best....ill invest in a propper tyga can but keep the maggot for the big rides i go on just so u can hear me over the r1s cbr1000's n gsxr1000's... is tere anything else i can do to improve my bike power wise??? will get a 14 front and 43 rear sproket...i have heard good things about hrc jet kits and airbox's??....but let me guess they are high range mods right?

This may help, from another thread

35 engine and carbs, fit an ignitech cdi and hrc jet kit from Rick, get a TPS from cbr 400, tyga twin stack, some sort of under carb air tray and run the carbs semi-open (just a filter on the airbox baseplate). This is a high torque road setup, which is going to be just as smooth and fuss free as the original setup once jetting and setup is done.

And when you come to jetting, sort out your main jet first, then the pilot screw/jet and finally the needle taper/height. And use Ricks method of carb sync before you do anything with jets..

wow thanks a milioln will definately look into that sounds expensive i have to save som pennies can all that be acheived by myself or do i have to get it taken to a wrkshop..

rick olivers price list can be found here http://www.vfr.dk/Default.aspx?tabid=14 ... uage=da-DK" onclick="window.open(this.href);return false;

The twin stack isnt essential but will help, dyno time will be needed unless your a wizzard with carb settings. your definatly need dyno time to set up the TPS.

I have a set of carbs im building to this spec so i'll let ya know how it goes.

Hey dr_46
I am in Sydney and had a dyno tune and rejet done today in Carringbah, they handle a lot of formula 400 track bikes which our bike and the VFR is one of the main entrants in that class. They are helpfull and price is good as well and they know their stuff, A bloke named "Harley" handled mine and I was in and out in an hour and a half. I had a similair problem with mine it had an awfull flat spot from about 4-6000rpm.

Dyno sheets

[helby]

The Dyno and rejet all up cost me $186, The Bike is stock apart from a "Two Brothers" Slip on end can and it is for road.

awesome thanks heaps for that.. ill have to go have a chat with them...i might do a couple of suggestd things said on this posts and then go to them for a good tunning...i am a noob at this but have learnt alot every1 has been a massive help....if there are any more suggestions or advice it would be much apreciated...i will have millions of questions as i get parts but might take a while....sydney sux ass for rvf parts i have to order after market mods from the uk and asia...unless any1 knows a place here where they have these mods for a good price...i assume most of the fitting of the stuff listed by drunkn munky i can do myself its just the dyno tunning i cant and for a mechanic to do everything would cost an arm n a leg...

RB Racing has all genuine Honda OEM parts for VFR400 and RVF400 and also have aftermarket parts. Have a chat to them in person tho if you are able to get out there.
