just a forewarning, curtis is generally a couple months wait for engine work. the dyna can be found cheaper and just have the cam mod done instead of getting new cams. they should be able to get it done much sooner if you want just the cylinder done, just put it together yourself.

 

Did you send it to Curtis? How long did it take? And is it possiable for me to do it on my own? My friend of mine is very good at motor work.

 

he did not have enough time for my deadline to put together the entire engine so i sent him the cylinder and head and put the engine together myself. i know the trx/crf engine's better than i know any other engine so i was not an issue.
