OMG Posted September 1, 2021 Share Posted September 1, 2021 (edited) 99' bird with 65K so I'm thinking this winter might be time to have a look at valves. I stop at the Honda shop and ask if anyone has adjusted valves on a Blackbird. I get a somewhat blank look and he asks me what brand bike is that. I'm not kidding. Then I find out the oldest guy in the shop was born in 82'. It takes the service manager more than a half hour of looking at books so I leave and have them mail me an estimate, here it is. I can do it myself 'if' I can get shims. Edited September 2, 2021 by OMG Quote Link to comment Share on other sites More sharing options...
XXitanium Posted September 2, 2021 Share Posted September 2, 2021 The old CB1100Fs shared shims with Toyotas I think? Quote Link to comment Share on other sites More sharing options...

For people who I think are NOT in the know I use CBR 1100XX instead of Blackbird but I know, you were in a Honda shop. I should peek at mine but haven't.

superhawk996 Posted September 2, 2021 Share Posted September 2, 2021 Since it'll be an off season project without hurry, measure and see if any need adjusting. If so, pull those and buy the just the shims you need. Quote Link to comment Share on other sites More sharing options...
tomek Posted September 2, 2021 Share Posted September 2, 2021 2 hours ago, OMG said: I can do it myself 'if' I can get shims. Industry standard 7.48 mm Dia. shims. Irrc. They are widely available. Many other brands of mcycle use those plus there is aftermarket like Hotcams or K&L. The nice thing about Honda OEM shim is the fact they available in 0.025 mm steps unlike aftermarket- 0.05mm. So if you are anal about engines like I am go with Honda OEM shims. I always like to get valve clearances as close as possible. The OEM window, let's say 0.13-0.19 mm or 0.06 mm spread, is not good enough for me. I'd like to get them to within 0.01-0.02 mm. 1 Quote Link to comment Share on other sites More sharing options...

rockmeupto125 Posted September 2, 2021 Share Posted September 2, 2021 The aftermarket shims like Hotcams are readily available from cycle supplies online. Ebay as well, maybe even Amazon. Quote Link to comment Share on other sites More sharing options...
jon haney Posted September 2, 2021 Share Posted September 2, 2021 IIRC, shims for the early CRF-250 (or was it the 450) will also work, and they have a larger range of thicknesses. Quote Link to comment Share on other sites More sharing options...
JaBr Posted September 19, 2021 Share Posted September 19, 2021 I built this spreadsheet to track the clearances on one of my ZZR's when I did the shims. Will use it when I come to do the bird as well. Valve Clearances.xlsx 2 Quote Link to comment Share on other sites More sharing options...
singram Posted September 24, 2021 Share Posted September 24, 2021 I know I'm late to the party, but for both for the Honda F4i and another for the Kawi ZX6, 2 separate local dealers were willing to swap out the shims I needed with ones I didnt as per an online valve clearance calculator(looks like JaBr has one), even steven, no questions asked. Neither valve inspection/adjustment cost me a dime. As already mentioned, I'd measure first, maybe you wont even need any. I inspected the Speed Triple at the beginning of this season- deadnuts on.
