clean those plugs and make sure you have good gas and no vacuum leaks ,

Bad fuel pump ????

Yes head gasket could cause your symptoms

could be your head gasket , blown hose and overheating point that way

check the thermostate. it may be opening late.Check the cooling system and may be you need a good bleeding of air from the system.Hope this helps!

The fuel tap is operated by a diaphragm being opened by vacuum. The pipe from the inlet manifold to the back of the tap may be partially crushed. Pete

Looks like you have a fuel problem, check for restrictions in the fuel flow pipe,you may have to remove the carbs and clean the jets inside, remove airbox and check free movment of all 4throttle slides by placing your finger under the slide and lifting it upwards

If you have a BitTorrent client then there is a money-free, virus-free, English copy of the manual here.
I've downloaded it myself and all seems OK. If you haven't used torrents before then let me know and I can either give you a crash course or find some way of getting the one i downloaded to you.

Hope this helps.

I agree, the oil musn't have any water in it or it will damage your engine.
Whip the heads off and fit a new gasket set.

looking at your motor from the front wheel ......coil on left side bottom tower wire goes to first plug
on left, top tower wire goes to the last plug on right.

right side coil bottom tower wire goes to left side no# 2 or 2nd plug in . The right top tower wire
goes to 2nd plug from right, I hope that is what you were asking . I do not have picture but this
is simple enough. Ok Good luck

could be head or pump, but if no missfire or smoke from exhaust I suspect the pump seals, cheaper and easier to check and renew pump seals first then flush engine and renew oil and filter, then keep an eye on oil after that.

starter solenoid/relay going bad maybe? if the ignition switch was bad, it would be bad all the time and since you said its rideable 80% and doesnt loose any horse power, then its not the pump! if i helped let me know. Feedback!

should be like most 4cylinder bikes...left side coil #1 and #4 plugs right side #2 and #3 plugs. try it if it dont start, then i was wrong. but thats what is on my cbr.

If it works before plugs changes, then check the plugs wires connections and conditions. If wires are good then check your battery OHM power else your rectifier/coil conditions.
Happy hunting

could be a problem with the ignition switch

hi,this might help,this is a fairly common problem,locate the bolt that holds the brake line onto the master cylinder,pump the lever 3 or 4 times,crack the bolt and bleed the air out of the master cylinder,you may have to do it a couple of times to get all the air out,it takes very little air to create a problem..put a rag or something down so as not to spill fluid onto your paint,brake fluid just loves paint..hope this helps...cheers

the oil filler cap is on the r/h side of the engine as you are sat on bike...just above the r/h foot peg..its on the clucth cover...at the bottom of this is also the sight glass for how much oil is in the engine

try using 0.14 -0.15 mm

Seriously just get a haynes or the very good clymer work shop manual,also try your local collage and go on a basic maintinance course. You require quite a lot of info there.!
