Picked up an 87 VFR700 But....

are there any diagrams online I can find about where all this stuff is so that I can romove the trash. lol what should I use to cap it all off.

 

Manual Time

Do you have a Honda Service Manual? It will answer all of these questions you have and more. Then, you do not have to try and interpret peoples explanations. ie.- Carb Cleaning. Spraying "Seafoam" is not rebuilding/servicing your carbs. You need to disassemble the four carbs and clean out the passages, carefully. They use very soft brass jets, and passageways. If you have never done any of this, don't be afraid to even drop in to a Honda dealership and ask at the Service counter, or stop a Mechanic. You could also take a picture and post it, and ask a question on the part you are stuck at. Try and find articles in the motorcycle magazines on Spring time preparation, or other articles.

 

Page 1-18 of FSM has diagram, it is a great pic and simplifies the mess. The bike came with a diagram on a sticker that is under the seat on the inner fender if it is still there. Basically you need to cap everything but the tank and bowl vent and caps can be bought at any auto parts store. It is best to weld the metal tubes from the head but you can cut them off just a couple of inches from the head and crush them flat, fold over and crush again.

 

was planning on replacing fuel filter but the honda place gave me one thats way too small. smaller than the tubing. so now Im on a quest for a bigger one. so people are stupid

 

so I chaged spark plugs. cleaned the airbox and air filter really good. and the intake plate/ float chambers?

I checked the battery. 12v. when starting bike 9.8 bike running 13.5. 5k rpms 13.8ish so battery is fine.

I am guessing stator or rectifier is bad?
also replaced fuel filter with a really nice one

 

I also found rust in the tank so I am using the naval jelly technique

 

Bike will not start anymore. Checked the plugs and theres spark. I opened the screw on the carb bowls and fuel comes out. but it just wont start.

 

carbs cleaned and runs on starting fluid great but i got everything hooked up. tryed with relay and with it jumped but the pump is pumping but not bringing the fuel through. I tryed blowing through the pump and air passes through valve. tryed another fuel filter didnt work if I break the seal between hose and filter fuel flows. any ideas?

 

make sure the fuel filter is on the right way...It should have an arrow on it pointing the way the flow goes.......

 

yupp did that and used different filters.

 

fuel pump pumping

 

sounds electrical check the kill switch

 

clean the carbs

 

it starts off starting fluid spray but not of gas. I tryed grav feeding it still no go. I just cleaned the carbs really well.

 

Stay away from using starting fluid as it can and will damage piston rings, pistons and cylinders !!!

 

did you mess with the boots? try taking the carbs back off and reseating them, also make sure that the boots are on correctly. I know sounds wierd but they do go on a certain way...trust me... also if you did pull thenm off you should think about replacing them as they are probably the original ones and are over 25 years old....

If you didn't take the jets out and clean them I am gonna guess that all you managed to do was break a shit tomn of dirt loose and you gummed up the jets. spraying starter fluid to make it run you are by-passing the jets.. just my thoughts....


How many years did this bike sit before you bought it?

 

Cleaning the jets was my problem on my carb clean, remember I had that surging issue crusty, it all came down to not cleaning the jets, mpad I know it seems like your going in circles, you get over one hurdle and 3 more pop up, I listened to these guys, was on here every night with new issues and after patience, not being afraid to revisit an area I thought was good, I got mine going and she is still a daily rider. If you truly like this machine time and patience, put you hands on everything, inspect everything, just because it don't look old to the naked eye doesn't mean it's working like it should, not knowing the history on how long it sat, I would break her down as close to frame as your comfortable with, take pictures, lots of pictures how it looked before you touched it, how it looked after you took it off and most important where it was when you sat it down, you will save yourself a lot of headache later and you will have the comfort of knowing whats actually between your legs if you venture too far from the house (no feeling is worse that getting outside you riding range on a machine you don't trust) and the real heartbreak you want to avoid that got me 3 times, getting it all back together thinking your about to hit the road only to find out something you could have fixed when she was torn down is broke now and you got to tear her back down. It's winter the nights are long get ya some good shop lights and take your time, she wont ever leave you stranded if you do.

 

I took the carbs apart completly. every jet every spring and every valve. and cleaned them all. I scrubed the jets and wire through the middle of them. the boots lloked to be sitting right. I followed toe cutters intructions of putting carbs back in.

 

the boots you need to make sure are on the right way...there is a certain way they go on they have to be positioned correctly as wierd as it sounds.. did you set mixture screws 2 1/4 turns out? and are all the sync screws back in? ... go back over what you did step by step did you hook the fuel line and the vacume line up correctly? you may be dumping fuel into the wrong part of the carbs ....you know the fule "t" and the air "T" that connects the two sets of carbs together? make sure those are correctly hooked up
Don't get discouraged it will come around....

 

Fuel is going into the bowls I am sure of that. I think that I ma have another issue with the pilot jets. I going back to check them again. a/f screws are 2 and 1/2 turns out. sync screws in but that would only affcet the quiltry of the way it runs not running its self
