Hi Everyone. Im in the midst of my very arduous VFR streetfighter build. . One thing that needed to be done was replacing the head gaskets after pulling the top end apart (some crud fell down the intake while removing the 20 something year old carburetor boots) When i received my new ones i noticed a small difference from the original. The stock part has a small restrictor in one of the oil holes - ive pointed it out where it is in this pic - The new parts however, have a full size hole , so im wondering why the difference? anyone know what this particular hole is? oil return/oil delivery? any info here would be swell.

Thank you for accepting my membership. I have just bought 1990 VFR750F. Two owner (I’m the 3rd). The seller had owned it for 25 years. 58000 km. $2000 New Zealand dollars. Ridiculous amount of bike for that money. Has the odd bump and bruise, but pretty original. I’ve taken it out on a few day rides and love it.

Well my love for VFR´s started back in the late 80´s when I came home after a motorcycle show and did see on all the brochures that I did bring home, and in the Honda one I saw this pic: Still got that broshure (have to scan and post a better pic that this found on the net Done!) Anyway, did take a bit more than 10 years until I did buy a 1987 in dec 2001. Pic from 2008 in Germany, taken by V4Rosso! I had the bike until Jan 2010, when I got tempted to get a bike you get more modern rubber to, got a 5th gen. Selling the 1987 RC24 is what I have regret many times....never felt the 5th gen was "my" bike, even a good bike! Eventually sold the 5th gen spring 2015, and after a short love story whit a sweet 1985 VF500FII traded it for a 3rd gen. Nice bike in many ways, might be best looking VFR (at least as red) but still my RC24 fever is bad. Now I have one that might buy a 3rd gen.....so the fever for a RC24 is even higher! Did go and look at a 1989 RC24 in a shop yesterday, a red as in the brochure Was sweet looking in a short distance, had a test ride, even had a rough idle (carbs in need of a clean)did ride like a champ even 101k kms on the clock and a slightly leaking exhaust, but had no front brakes! Closter inspection gave clear the rotors had surface rust deep enough to need replacement (even not that old), and a rotten collector box. Tires dot stamp did say 2006/2004! Also closer inspection did show many panels did not fit properly, and as I did take of the seat the rear parts attachments where broken or glued...also sign of a repaint. So even it had the passenger seat cover in the top box, at a last price of 1300€ (1450€ asking price) it was a walk away! Now I have 2 different options to look at, a other 1989 and a 1986. The 1989 (EU only model like the red I was and looked at) is from a local seller that lives about 2 h drive away, its color is black, not my favorit color, but has an exelent history, only 2 owners of witch seller for 20+ years! Has 134k km on the clock.....quit much. But these last, and looks very nice in the pics, so worth a look I think. Asking price is 1550€...Will go and look at it Wednesday August 3rd. , the 1986 in a shop quit far away, about 5½h drive. Asking price is 1290€ Looks quit clear even has also about 130k kms on the clock. Tempting in the way as could be titled as a classic next year if pass inspection (needs oem style brake discs as oem blue seat cover as oem rear turn signals for that at least) and I would get cheap insurance! Looks good in the pics, but that do most bikes! Lets se how it go.

Ok. So I believe I have found the leak from my carbs. It seems to be that the fuel joint gaskets (Items #7 circled in red in the photos attached). The problem is that my Clymer's book doesn't tell how to disassemble the carbs to this degree. It just says refer to a local dealer. I do not have the money to pay someone to repair it at the moment so I am going to attempt it myself. Does ANYBODY out there have a manual or web link that may have step by step instructions, with photos if possible, that I can refer to in order to get this completed? I have the new seals/gasket sets just need the know how. Thank you for any of your help.

Intro I've been the proud owner of a 1991 VFR750F for about a year now, and I finally decided to join a couple of the VFR forums! First, a little about myself. I am in my mid-20s and have been riding for about 6 years now, and have owned four different bikes now during my riding career. Around the end of last summer I decided I wanted a little more than my 1983 KZ550 had to offer. While it was a solid bike to ride around Milwaukee, and it carried me on many adventures during my two years owning it (see Pikes Peak pic below), the sketchy handling and the pedestrian power left me itching for something more. I have a couple friends from college who simply rave about VFRs. Personally, I had no experience with the bikes, but their praise of the performance and reliability of the VFR piqued my interest and I decided to browse Craigslist to see if anything interesting was out there. Immediately, I was drawn to an ad for an Italian Red '91 VFR750F 30 minutes South of Milwaukee. There were only three pictures, but the bike looked very complete so I decided to take a trip down to take a look in person. When I arrived, I was immediately impressed with the condition of this 26 year-old bike. The fairings were complete and the paint betrayed no signs of the bike having been dropped. While talking to the owner I discovered that the original owner sold the bike only 4 years ago, and has swapped hands only once since then. Who knows if that story is true, but I could care less given the condition of the bike. The current owner showed me receipts of $1200 worth of work being done to in July 2015, including new fork seals, new chain and sprockets, and new front and rear Dunlop Q3 tires. He was forced to sell it to pay for medical bills after having shoulder surgery. After hearing this and inspecting the bike in person, I decided I needed to take a test ride. The bike immediately started up and after warming for a couple minutes I took off down the road and headed to the nearest freeway on-ramp to test the bike at speed. Now, prior to this point I had never heard a V4 exhaust note in person. Needless to say, the second I twisted that throttle on the on-ramp I knew there was no way I wasn't buying this bike. That exhaust note through the Yoshimura muffler was simply intoxicating. I had never heard an engine sing, growl, and roar all in conjunction. Everything on the test ride checked out, and I brought it back to the seller. We negotiated down to $2600, and I had my first truly eye-catching motorcycle in a condition I could be proud of. I may have paid too much, but I felt the condition of the bike along with the recent maintenance done to it justified the price. Mileage read just shy of 25k. My VFR hasn't missed a beat over my first year of ownership. Without complaint it will satisfy both on-ramp heroics and day road trips through rural WI. It really is a do-anything motorcycle with a hell of an engine (that exhaust note!). It's tucked away for winter now, but I am already looking forward to the adventures it will take me on next year. Bike modifications: Corbin seat (torn seam right where my butt sits, seems to be a problem due to the pressure put on here from the rider and the lack of padding under the area) Yoshimura muffler Bar ends with cruise control Maintenance/repairs I have performed: Oil and filter change (Castrol 20W-50 part synthetic oil, Honda filter) Air filter replacement (OEM) Replaced miscellaneous/incorrect screws and fasteners ($8 for a quarter turn screw? Better not lose any) Antifreeze replaced (with Honda blue antifreeze) Removed non-functional 90's security alarm kit and cleaned up the wiring Replaced stripped out gear that drives the cable to the speedometer Replaced missing seat locking mechanism Wash/clay/wax (some knucklehead hit the bike with an egg while I was parked outside of Lakefront Brewery in Milwaukee. Couldn't believe it. Scratched the paint, but not in a very visible spot. I was finding egg yolk amongst the wiring around the triple tree months later) Plans: Replace voltage regulator with R1 unit I had from my old FZR600 (the wires going to the OEM unit on the bike are already crispy) Replace rubber brake and clutch lines with stainless steel lines Qustions: Hard luggage. I would really like to set this bike up for touring, and I see that at one point there were many hard luggage options. Do any luggage manufacturers still produce hard luggage for the third gen VFRs? Everyplace I look seems to be out of stock. Speedometer accuracy. The speedometer and odometer tend to read about 15% fast compared to mile markers on the freeway. Do these speedos tend to read fast? I don't want to rack up a ton of illegitimate mileage. Once I get the bike out of storage next season I will count the teeth on the sprockets to see if the gearing has been changed. I hope the sprockets are correct, because I really enjoy the acceleration the bike currently has. Valve clearance. The bike reads approximately 26k miles now, and I have no idea if a valve adjustment has ever been performed. Should I be worried if the bike runs great? I have performed valve clearance adjustments before on inline 4 engines, but I hear it is a real pain in the ass on the V4. Lastly, this thread would be worthless without pics! Some were taken by a GoPro, in case you were wondering about the distortion. (And yes, I always wear gear. Except for that photo :))

I am having a problem with my VFR750. It has a problem revving up under load past 6000 rpm. I have been told that if I adjusted screws that are circled that it would fix the problem. Here is an explanation of what is happening. When I am riding it will do fine in the lower rpms up to about 5500-6000 rpms. After that when open up the throttle (from half throttle to full throttle) it surges a bit and the rpms will actually start falling slowly while losing acceleration/torque and it sounds as if it bogging. I worry messing with the carbs. I am hoping someone has had this issue and has a fix. Thanks. If anyone has any questions please let me know.

Hello All, I had a problem with my VFR. I was riding home from work last and it started backfiring and feeling under powered. Also when I get on the throttle it surges and feels as if it loses torque. Especially in the higher RPM's it happens. Around 6000+ RPM it will surge more frequently and lose torque/acceleration. It seems to me that the RPM should also climb a lot quicker then it does. It will also backfire during compression braking, holding RPM and accelerating in the higher rpm. It usually runs aroun1000-1100 RPM at idel but now it idles anywhere from 1000-900 RPM I know it's not a big difference but it was enough for me to notice. Here are the things I have done to troubleshoot/Fix the problem. 1. Checked the primary coils and secondary coils. (Within Service Manual's Ohms range) 2. Checked the pulse generator (Within Service Manual's Ohms range) 3. Checked the Ignition Control Module and all test were negative. 4. Bought & replaced old spark plugs with NGK spark plugs. (I did not do a leak down test because there is no smoking or oil smell in the exhaust, Should've I done one anyway?) I am starting to wonder if this is a carburetor issue or something else with fuel mixture or delivery. Come to think of it the fuel pump does project a loud repetitive clicking sound every once in a while. I really hope that it is something besides the carbs. It terrifies me just thinking about taking those off. I have the original service manual which shows excellent visual and verbal instructions. I have just never dug that far into the bike before and it makes me nervous! If any of you have any suggestions on what to do please let me hear them. It will be greatly appreciated and Thank you in advance.

For sale on a local sale site.....I will not buy it, sure different (not my style), and seem whit some effort (at least tank paint or a wrap?), even budget?
