The old Six pots are indeed 'Too Manly for the discs' and bind regularly causing the discs to Warp... I went through 4 sets of discs on my YZF before the current set up.. I am currently running R1 Blue Spots PFM Iron Discs EBC Organic Pads (to match the Iron Discs) with a little material removed from the leading edge of the pad to avoid the pads fouling on the disc buttons (as mentioned in the earler post) - cheaper than running Ducati Discs and I like my PFMs An R6 Master Cylinder with the YZF Lever (the stock YZF Master Cylinder is designed for 6 pots and not 4 so feels very solid and does not provide much feedback) The bottom of the forks were filled out to clear the calipers as per previous posts, but nothing difficult...

Carbs are a pig to set up with the Exup and a straight Dynojet, but can deliver some good benefits, my bikes punting out over 110 at the rear wheel as measure at PDQ.. Weight is definately the easiest thing to loose, and there are plenty of ways to do it.. not least ditching the ton of Stainless steel end can..... I would advise against a top end only swap as there are lots of issues around the oil ways and pressure, the easiest option is a straight switch to a 1000 exup or Thuderace motor, which is easier and I can supply you with a few useful links if you are interested.. Unsprung weight is good to loose but at the same time will remove some of the YZF's super stability... these things are renowned for their handling if set up right.. Suspension upgrades are plentiful and the only limit is how much you want to spend.. Great article in Performance Bikes recently with a YZF running ZX10r Cartridges in the forks.... Looks like a good mod... and a damn sight cheaper than a set of Ohlins..lol... Dropping 1 tooth on the front cog improves acceleration... Andy

Same problem Pal, I am on my second set of stock Emulsion tubes on my YZF750, and am now looking at getting a set of replacement tubes from these guys. www.factorypro.com/prod_pages/indexmake.html I have tried eveything else, Jets, Needle heights replaced the Exup motor.. (and had the exup valve replaced by the dealer when I first diagnosed the problem - totally unnesasarily as the original part was fine - at great expense.. thank god Motorcycle Sh1ty went bust).... even took the Bike to PDQ for a full set up on the Dyno... 112 on the back wheel but still with an intermittant fault.... My Carbs have been off an on the bike more times than I can count ..... and only when I swapped the tubes out did the running improve for the 10k it took for them to wear oval... Andy

If you have checked your Carbs and the Exup and all appears well and your float heights are good then you may have worn emulsion tubes (quite common on Yams (my YZF750 has been through 2 sets) this causes the bike to run rich and foul making the fueling side of things really difficult to get right. www.factorypro.com/prod_pages/indexmake.html Check out this link I am about to order a set of their replacement emulsion tubes for my YZF750...

Hi there Not sure about the R1 Swingarm but I believe the YZF750 arm is a fairly easy swap if you are looking for a braced type. As for the seat unit anything is possible but you may have issues like exposed frame rails or having to make up a special subframe for your bike to suit. Andy

Hi there I did this with 2 different FZR 400s and its easy. I take it you have the earlier FZR400 with the 2 removable frame rails? and no Exup If so you can just pretty much unbolt your engine drop it out and put the 600 unit back in. You can use your existing loom and rad as they are near enough the same as the 600. You will need the 600 exhaust and carbs though, the airboxes are pretty much the same... If you have an Exup version you will maybe need to swap the loom over. I will add some pics of my 4/600 later on (this is the later bike which needs a couple of plates made up to match up the uper engine mounts). But if you have one of the earlier bikes this will not be necessary. Check out my Gallery pics for the FZR400 to 600 Build (not many pics but its in the days before Digital and Mobiles with decent Cameras.... LOL Andy

Anyone know the Spec for the swingarm Bearing on the YZF750R (95) Model, need to replace mine as part of the rebuild but would rather not pay the £48 for a kit when you can buy direct from bearing suppliers for £12 a pair ish Cheers Andy

Hi Guys... First the intro, been a long time Yam owner in fact for some 20 years now and never been without a bike. Started out with a Grey Import FZR400 Then a UK FZR400rr which had been put in a field by the previous owner I streetfightered it, fitted an FZR600 motor, Re Sprung RGV upside down forks and an narrowed R6 Seet unit.. Brief excursion with an italian pile of Poop... Supermotoed Aprilia Tuareg 350... And finally onto the current beast YZF750R - I will get some pics up soon Anyway - circumstances meant the YZF was dry docked and has been stood for a couple of years (well 5 to be exact) and I have finally started the recomisioning process.. carbs cleaned, tank cleaned, etc etc new battery ordered.. As part of the process I am updating the body work.... top secret but if it all works out will look preety good, swapped the front calipers to R1 Blue Spots, PFM Iron Discs and some other minor tweeks... Any other members up in the North... Perth/Tayside Area????? Andy

Looks Great, Am working on a similar project myself, how did you get round the following: - Front Wheel Fouling on the Tip of the Belly Pan. - What Brackets did you use to mount it - standard YZF screen Brace - Did you have any issues with the clocks clearing the screen - Did you have any problems with the bars hitting the inner fairing on full lock? Will try and get some pics posted as soon as I pay me membership at the end of the month... Andy
