exhaust valves

<< < (2/3) > >>

no sub for cubes:
this is my 88 exhaust valve setup me thinks its diff to what your describing cbx....the cogs are showing signs of wear a spline missing on each valve cog,i was gonna just throw them back in like that but as i now have no markings and have spent time and money doing the best  i can i might as well invest in new valves as well .

cbxracer30:
Yes yours are differrent than I thought , here on this side of the pond I don't think you can order them any more. You know what maybe I better let some else help out since I run the newer style. Sorry I couldn't help CBX

RoostDaddy:
cbx, this is like doughboy and eddie's old set up.  Maybe we can ask one of them how they're adjusted.  I believe it is simailr to the new style, just without the gear.

looks like same prob here cbx,i called around breakers and main kwaka dealers only to find out the 88 valves are discontinued  :?...for now i could do with someone with the same valves as me to confirm another way of setting them without the dots on the cogs,long term it looks like im gonna have to try and find a later cylinder,does antbody know if an 89 onwards cylinder will  bolt straight on?

Looking at your pics the valves look like they are timed like a tecate. There aren't little dots but one tooth of the gear is shorter than the rest and you line that one up .you can see that on one of you valves for sure.I think that was the way my 86 K5 was also.
