crmx0312 Posted October 23, 2005 I have the hotcams valve shim kit from my CRF250. Are they the same size for my RMZ...7.48mm....Thanks. Also if i only have to shim the exhaust valves do i have to remove the intake cam as well or just the exhaust...Thanks for the help Share this post Link to post Share on other sites
MotoX178 My Ride Posted October 23, 2005 Kit will not work, same diameter but they are to thin usually. You need the kit that has the thicker shims. My friend has boths kits and has never needed to go as thin as the CRF kit, if you do I think you may have some valve issues. To shim the exhaust valves I do not think you will have to take out the intake cam, may just want to make it easier though. Share this post Link to post Share on other sites
Kx250FRiDeR651 My Rides (3) Posted October 23, 2005 um ya they are the same size...thats what kit i have.. go on the hotcams site or tt store and look it up...the kx250f/rmz uses the 7.48 kit Share this post Link to post Share on other sites
MotoX178 My Ride Posted October 23, 2005 Yeah they have two kits, one is like 1.5 to 2.5 and the other is like 2.5 to 3.5 or something like that. The CRF uses the smaller kit. They are both the same diameter 7.48mm just different thickness, KXF/RMZ uses the thicker ones. Share this post Link to post Share on other sites

crmx0312 Posted October 23, 2005 Really. I just went to the hotcams website and they only list a 7.48mm and a 9.48mm. They sat the 7.48 fits the RMZ and the KXF as well as the CRF250s and the 9.48 is for the 450fs. I didnt see any different shim sizes. Do you know where i can find it.Thanks Share this post Link to post Share on other sites
MotoX178 My Ride Posted October 23, 2005 The kit my friend lent me for my KXF is a 7.48mm with sizes 2.45 mm to 3.5 mm in thickness. Share this post Link to post Share on other sites
shurshot Posted October 23, 2005 You get both kits when you buy the The Hot cams shim kit. 1.5mm to 3.5 They work, but are not as hard as the OEM shims. They are a good deal. You will need shims from 2.8 to 3.1 inthe KXF/RMZ. Share this post Link to post Share on other sites
motoxbluedog Posted October 24, 2005 The KX250f and RMZ250 specify shims from 2.50mm to 3.50mm. (.025mm increments) YZ250F is 1.20mm to 2.40mm (.05mm increments) Honda CRF250 1.20mm to 2.90mm (0.025mm increments) Husqvarna TE250 1.6mm to 2.60mm. They are all 7.48mm in diameter. 450's are normally 9.48mm and different shim ranges The Hot Cams kit supply shims in .050mm increments and the original kit only had shims to suit the Yamaha. They then doubled the size of the kit to cover a much bigger range. Be aware of the shim range of your bike and don't go outside that range. I've seen people installing smaller shims outside the range when the valves wear enough. They're asking for trouble. Share this post Link to post Share on other sites
