Go to your local pound shop. buy their pack of kitchen brushes then get yourself a tin of oven cleaner, go home, grab a bucket of hot water and your preferred soap, then have at it, don't leave the oven cleaner on to long (5mins) then rinse it off, run your motor till it's dry and job done, oh yeah tea & a biscuit helps as well!

Take the cam cover off and use a feeler gauge to check your gaps, easy and straight forward. Should take about an hour to do.

Hi and welcome to the YOC, love the FJ lot's of grunt miss my old bus.

Beautiful Simon, I bet the local fishermen just LOVE you!

Well to start you need the ignition barrel the tank lock plus the seat lock. New, more than the bikes worth, used from ebay or some such anyone's guess. Found these tho from Germany http://www.ebay.co.uk/itm/YAMAHA-XVS-650-4VR-DRAGSTAR-SET-IGNITION-SWITCH-/ You don't say what year your bike is so had to make a best guess for bike. That's why you fill in the details so folks don't waste their time finding stuff that's wrong|| About £80 quid I think so not a lot really but your tank lock (if it's closed) will be a right bastard to get off, your going to need a drill the size of the key barrel and time and patience to drill it out so you can turn it to get it off. Been there done that! Also nice if you say Hello in the new members section (HINT!) just sayin.

Different in the car world, you can remove and replace the VIN tag unlike bikes where it's stamped into the frame.

Here you go Sacha, just for you and the girls !!!

Welcome to the YOC, good luck with your new baby!

Easy if you have the manual and some where warm(ish) to work. Should take about 2 hours with a set of tools and a cup of tea. Save yourself some money by taking it apart yourself and just get the bits that are fucked to the local engineering shop.

Have you checked the carb diaphragm? if that's split then you will get odd running, it's a rubber widget inside the carb, on top of the slide.

Merry Christmas to you all, may you get what you deserve!

Can't see why not, after all both are Yam's and V twins other than that the ECU and exhaust might need to be swapped as well or modified "to fit" mind you the difference might not be in the engine as such but may be to do with the gearing of the bike, a 650 should not be monstrously different to a 750 after all! Never ridden either so not in a position to say but if your missus is determined to have the extra grunt then your going to be in the garage fixing her bike or eating your XMAS dinner in the shed! You might also need some plate steel to make up some engine mount brackets for those little differences in style and shape, believe me those few mm will keep you up at night if you don't, been there done that. Might also be an idea to say hello in the new members section just so folks know your not a one hit wonder, just sayin! Just had a scout round the net looking for threads that match yours. It seems that lot's of folks want what your missus want's i.e. lower revs and longer gear shifts, but the consensus is that the gear ratios for the 650 will not match the 750 drive shaft, so even if you swap out your 650 lump and swap in the 750 the rear wheel drive assembly will not match so your going to have to use the 650 rear drive and that defeats the objective cos you have just moved it all for no benefit. Sorry about that but it might be best to flog both bikes and buy one that she does like. Just so we're clear here, you swap the 750 into the 650 frame the diff will NOT mate to the 750 drive.

Yep as above, you've fucked it! Take it apart and see how much damage there is, if the mains / small end and barrel are toast look for a replacement motor. Not a "cheap" option but it means your bike will be back on the road quicker than faffing around tryin to fix it in the dead of winter. Then you can rebuild it while still having a bike to ride to work on. Plus you can sell it on once you have your original motor sorted.

Asked my wife to read this Sniff, Apparently I'm now sleeping on the sofa!!!

Yeah "READ THE F**KING MANUAL" is what your supposed to do but how many actually do?

Looks to me like a welded plate, so for what it's worth cut it off and take it to your local welder and get him to replace the plate with some nice shiny steel. Better still leave it on and get him to remove it and then he can see what needs to be replaced, yes by the way almost certainly structural.

Ok who ordered the LARGE fish?

Yeah it's amazing when you think your saving a few quid to find out you might just have well spent the extra money and bought something that didn't fail, the gauges are good tho. should have bought these instead

Yep that's the ones Pilninggas utter frigging rubbish, thanks for the tip Drewpy will get some asap.

Ok folks just a quick idea here. So been meaning to balance the injectors on the FJR since I put it away, finally got round to it and stuck the balance tubes on the little tit things and merrily started to balance it all. Will it f**knig balance out NO! go through the procedure again and reattach all the pipes and make sure the right pipe is on the right tit then check to see if the gauges are working ok still won't frigging work. Finally get round to checking the ends of the rubber pipes that connect to the bike (running out of things to try at this time) find that the rubber is stretched just enough to let air in thus messing with the balance calculations, so chopped 1/2 an inch off the ends, seems that if you use these things on different bikes with different sized attachments and it's cold enough to freeze your nuts off, the rubber stretches just enough to make a real difference. So if your going to do this during the dead of winter check for a TIGHT fit before you launch into this balance palaver. Just thought you could save yourself an hour of fruitless fault finding and swearing! Stay safe.

Well done mate, take care.

Smart Noise/Malleus, just so makes a lot of sense.

Wrong place, you need to check which Country it is in! Good luck. Lugar incorrecto, usted necesita comprobar en cuál país está adentro! Buena suerte

Found this if it's of any use? http://www.servicerepairmanualonline.com/category/motorcycle-manuals/yamaha/

Almost certainly an electrical short/fault, take it to a dealer and see if it's a know fault.
