I have had my old Honda Crf 450r 2002 for about 10 years now, I don't get around to riding it much but id like to breath some new life into it. I basically would like some advice of things that should be rebuilt or modified. I don't want to go crazy as old as it is I plan to turn it into a supermoto, as it is still a green sticker in California, the only thing I have noticed is that the air box has a terrible seal and people recommended changing it out for a 2004 sub frame and air box ( is this worth it? curious if it will really do that much? Thus far the forks have been rebuilt but the stock springs remain as factory recommends them for my weight about 195 with gear, Im 5'11 175. My biggest problem with the bike is the suspension literally feels like it is non existent, its so stiff,and I understand its a race bike but something seems wrong I'v ridden lots of race bikes, i have places to do a rebuild but again to keep the stock sping as it is sert for my weight. the front seems better since the rebuild but the rear makes me feel beat up after a day of riding, basically id like to know if i should: 1. rebuild the carburetor, I've never touched it, and it seems to be doing fine now but Im curious if its recommended. 2: Should i rebuild the rear shock, will it do anything? 3: The brakes suck but now sure what the best plan of action would be there as well? I'm sorry I know this is all so broad just lots of questions and never posted here. Looks like an well connected group and I figured someone can give some advise. things i have done thus far, The engine has been rebuilt top and bottom, trail tech odo, fmf header and slip on, and thats about it, i rebuilt the motor with mostly oem parts with a few exceptions. thanks guys -Josh
I have a 03 450 that I just got and it runs great! I love my bike and am big on preventative maintenance. I have searched the threads on TT and have not found any descriptive threads on how to check valve clearance or adjust them. Just by looking at them, I can see that the intakes need to be shimmed and the exhaust valves can be adjusted quite easily unless one needs to be adjusted differently than the other. I tried to do it last night, and lined up the marks on each side to get the piston to TDC to check adjustments and could not get any readings on tolerances on either the intake nor the exhaust. I moved the crank a little bit forward and got a .011 reading on the exhaust valves. I read in a thread that the spec was .011" for the left one and .014" in the right for the auto decompressor. The spec I am using for the intakes is .006" Are these specs correct? :excuseme:The only issue is that the adjustment for the exhaust valves is one and the same. Different from my KTM where you can adjust each valve individually. No matter where the cam was on the intake valves, I could not get any readings. Does anyone have a thread, website, downloadable manual, or article on checking and adjusting valves in these beasts?
