Burning oil is quite common with the YZF`s and FZR`s. With the YZF750, its usually the valve stem seals, might be worth pulling it apart and checking your valve clearances at the same time. Although i`ve had a few 750`s, never had an issue with using oil, apart from the one that had a FZR1000 motor in it, that had to have the stem seals replaced as it had the same problem as yours.

Just an update, never liked the fat, wide rear end on the Ace, so modifying a YZF750 rear end to fit. Almost there apart from a few niggly jobs and spraying it. Got a lot more YZF750 stuff to fit, forks, swingarm and front fairing.

The early R1/R6 bluespots do fit with a little work. R1 discs don`t fit, you need Ducati or Aprilia 320mm discs, which are a straight fit. Have a look here. http://www.yamahaclub.com/forums/index.php...4&hl=yzf750

Common fault with these is that inside the speedo drive, there is a washer with 2 tabs that drive the speedo, the tabs can sometimes break off. You have to remove the wheel to inspect it.

Not much can be done, other than a rebore. Cheaper to fit a FZR1000 or Thunderace motor.

Good point above about vibration with bike standing still. It sounds like your carbs need balancing.

Sorry, i meant pilot screws. They might need adjusting with fitting new emulsion tubes, bike may be running rich or lean. Standard setting is two and a half turns out.

100/120 miles per tank sounds about right. So changing the plugs has made a difference? That could point to the coils or plug leads. Have you checked those?

Wouldn`t have thought compression would be low on 26000 miles. Sounds more like a carb issue, are the carbs set up right? Air screws etc?

It also helps if you take out the top radiator mounting bolts, and move the radiator forward a bit. If you don`t have the plug spanner in the Yamaha toolkit, just buy a cheapy from Halfords, and cut it down to size, as a normal size plug spanner won`t fit into the plug hole. Its also worth cleaning all the crap out of the holes before you remove the plugs, and clean out the drain holes on the outside 2 plug holes.

Thats the oil/gas reservoir for the shock. Its only done for looks, and is quite safe.

Thunderace rear wheel is a straight swap The later FZR1000 Exup Foxeye model front wheel is a straight swap.

Here you go, bit expensive though! http://cgi.ebay.co.uk/Yamaha-Servo-Motor-E...5QQcmdZViewItem

As Madison has said, you need to keep the servo connected. The rev counter is going haywire as it acts as a fault indicator, showing there are problems with the Exup valve. You can get a plug in box that takes the place of the servo, can`t remember exactly what they`re called, might be "servo eliminator" or something like that. They were selling on Ebay.

Correct! Its an American thing.

The triple trees and stems are made out of different metals, so when you heat them up, they expand/contract at a different rate. The trees are softer, so will expand first, making it easier for the stem to be pressed out. Try searching for other Yamaha forums, you`ll usually get all the help from there. Heres a couple to start you off. http://exupworldwide.com/forum/ http://www.exup1000.co.uk/phpBB2/

Did the shop heat the shaft before trying to press out the stem? I know a lot of people who have had the stem pressed out when changing from YZF750/FZR1000 forks to R1 forks, never heard of anyone having one break yet. Maybe you could ask around for other Yamaha triple tree measurements, FZR, R1, R6 etc?

1. They are easier/cheaper to service. (4 pistons instead of 6) 2. The R1 callipers are of one piece construction, so theoretically no sideways flexing, so should work better. 3. Cosmetically, they look better, in my opinion! 4. The later "Goldspots" have ally pistons in, which are lighter, so less prone to sticking and need less force to brake.

I`ve used this place a few times, no complaints. http://stores.shop.ebay.co.uk/motorbike-gr...s__W0QQ_armrsZ1

No mate, FZR600 fairings are different, the Foxeye FZR600 looks the same, but is a different size, and has different mounting points, i know, as i bought one and tried. I`ve also tried an OW01 bodykit, again, it wouldn`t fit without some serious chopping and cutting. There are still places that sell the YZF750 bodykit, but most are overpriced and most are fibreglass. How bad are your plastics, as with a little effort they can be bought back to life!

The discs are from an early Ducati 916, fit straight on with no mods. I have a list of discs that fit, i`ll look it out for you, though most Ducati 320mm discs wil fit. As has been said, the only mods needed is to remove a piece of the fork bottom where the round part of the R1 calipers touch. Have a look here, a write up on doing this from start to finish. http://www.exup1000.co.uk/workshop/calipers.htm

wemoto.com sells fork tubes. Have a look to see if your model is listed.

You also need different brake discs, as the R1 pads catch on the 750 disc bolts.

Wemoto sell them for your bike. http://shop.wemoto.com/pictures.dyn?u=2147945qqq25672
