Stromer Posted December 14, 2018 Share Posted December 14, 2018 So, having just acquired my 15 FZ-07, it came with a pair of sparkplugs, and seeing as the bike now has 27000 km, I've decided to do an early valve check, TB sync, and coolant change while in there. Anyone know what size shims this bike uses? I have a 7.48 mm kit as that was for my last bike. Apparently not too many have piled on enough mileage for the task. I don't recommend this job for those not experienced with engine mechanicals. Enlist a friend who has done it before. I like to shoot for a clearance near the middle of the spec range, unlike most shops that use the go, no go, method, meaning, even if the valve is just within the tight end of the range, its a go and left alone. This leaves very little clearance for normal valve recession, which can result in a tight , and burned valve/seat, Doh! $$$$$$$$!!!!!!! I kept my old mercury manometer, so looking forward to getting at it. The workshop manual is pretty clear and has the all important torque specs. Also just received my FT ECU unit, so itchin to get it done! Link to comment Share on other sites More sharing options...
r1limited Posted December 14, 2018 Share Posted December 14, 2018 There is no way to predict what shims you will need. You will need a + and - range handy and measure as they are set once you get the cover off. “Laws that forbid the carrying of arms disarm only those who are neither inclined nor determined to commit crimes.” --Thomas Jefferson quoting Cesare Beccaria Link to comment Share on other sites More sharing options...
Stromer Posted December 15, 2018 Author Share Posted December 15, 2018 No no , I quoted the diameter of the shims not the thickness, I have a whole kit of shims Link to comment Share on other sites More sharing options...
rick Posted December 15, 2018 Share Posted December 15, 2018 according to this, 7.48mm is correct https://www.ebay.com/itm/Hot-Cams-HCSHIM01-7-48mm-Complete-Valve-Shim-Kit/332645552909?fits=Model%3AFZ07|Make%3AYamaha&epid=171170315&hash=item4d7338530d:g:DXIAAOSwSXFa8kyO clean living.

twf Posted December 15, 2018 Share Posted December 15, 2018 Bike uses 7.48 shims. All engines I have done so far were in 180-200 range. Buying kit is waste imo, not enough of same size to do engine. Better off buying refill kits or individual. Link to comment Share on other sites More sharing options...
rick Posted December 15, 2018 Share Posted December 15, 2018 He already owns a kit. 180-200, in what units are those numbers? Link to comment Share on other sites More sharing options...
twf Posted December 15, 2018 Share Posted December 15, 2018 Numbers stamped on shims, 180=1.8mm-200=2.0mm Link to comment Share on other sites More sharing options...
twf Posted December 15, 2018 Share Posted December 15, 2018 Another thing is kit shims go by .05 jumps while stock ones are by .01 so getting exact numbers with kit may not be possible. Link to comment Share on other sites More sharing options...

Premium Member norcal616 Posted December 15, 2018 Premium Member Share Posted December 15, 2018 As far as I know only the factory uses shims in .001 increments... Even looking at the parts lists and aftermarket kits/bulk it's all .005 increments... I'm recalling all this info from the FJ-09 forum... I don't recall any sources for .001 shims unless you build the engines or work for the factory shim supplier or have a junkyard full of CP2 motors... 2015 fz-07- Hordpower Edition...2015 fj-09- 120whp- Graves Exhaust w/Woolich Race Kit- tuned by 2WDW Link to comment Share on other sites More sharing options...
twf Posted December 15, 2018 Share Posted December 15, 2018 Honda has them in .025 increments. I used to buy from local honda dealer when I needed. Or I would trade with service department. Some dealers don't mind trading so you should ask. I do build engines and I have huge collection of all sizes. Link to comment Share on other sites More sharing options...

Stromer Posted December 16, 2018 Author Share Posted December 16, 2018 So finally got the bike stripped down and measured valve clearances. Glad I did! All intake valves except one are just barely within minimum spec, one is 1 mm tight. Only one exhaust valve within spec at .26mm. The others are tight at 21 and 22 mm, so heads up to those waiting for the 40000 km check. I was able to swap around and use some of my own shims, but As Twf pointed out, my kit has .05 increments, so off to see if I can beg my local shop for closer shims for the last 4.

twf Posted December 16, 2018 Share Posted December 16, 2018 If you don't find them let me know and if I have what you need I will trade you. Link to comment Share on other sites More sharing options...
Stromer Posted December 18, 2018 Author Share Posted December 18, 2018 Thanks twf, got some local, installed and clearances all good, plan to reinstall rad, check TB sync, and then install FT ECU over the weekend. Double checking everything as I go, as I don't want to hear expensive noises later, just a little more valve ticking. Link to comment Share on other sites More sharing options...

Stromer Posted December 20, 2018 Author Share Posted December 20, 2018 Sorry didn't take pics. As previously mentioned I do not recommend this procedure unless under the guidance of someone with experience and tools. The workshop manual from Yamaha covers the steps but assumes basic knowledge of performing tasks listed. So again, if the procedures in the manual don't make sense, find help locally or have your dealer do it. . Link to comment Share on other sites More sharing options...
