Titanium Coated Valves??

[Dantheman250]

Hi, i have a crf 250R and have had it for a little more than a year now and have had to get new valves a few times. even if i shim them they still wear out. im wondering if i should look into the titanium ones, and how much they are. Thanks!

Put some Kibblewhite blackdiamond valves in with the HD spring kit you'll be good for a long long time.

if you have a crf250r you should already have titanium valves. my friend has one and they came stock. if you race then they will wear out fast, because of the high rpm. the reason titanium valves are used is because they are more lightweight than steel, but they dont last as long. if you dont race then you probably should just get stainless valves and heavier springs. make sure you adjust thenm as well. also this bike is a race bike, and the parts arent supposed to last very long anyway. very high maintenance.

So kibblewhite blackdiamond are the longest lasting, and titanium is the best performance? what about stainless steel and steel? how long do they last?
