Greetings! So I have a new 14 wr450... My first new bike, yahoo! Thumpertalk is the greatest for info and I've spent the last year or so reading what's posted in the WR section, soaking up all the info I can... Am looking now for thoughts on the first steps with the bike. I know about the aftermarket stuff ( bar guards, radiator braces, frame skid plates, etc) so am not looking for suggestions there... Yet anyway.. The bike has less then one hour on it.. I have the comp ecu, the programmer for it and an FMF Q4 slip on.. So questions... 1) break the bike in with new ecu and slip on or break it in totally stock? How many hours until motor is broke in? 2) Dino oil or synthetic during the break in? (Don't need an oil/brand debate) The bike will run an all synthetic oil for everyday usage, in snowmobiles it's not good to run synthetic during say first hours in order to get the rings to seat (2-stroke). Does same apply to the thumpers? 3) grease everything - neck and swing arm bearings/linkage.. Besides those two areas, anything else I should focus on? 4) adjust the CO2. Um, seems all of my semi local dealers have no idea what this means or how to do it... The service shops seem to know everything and look at me like am crazy when I bring the subject up.. Can I ride this with out doing damage/wear to stuff w/out having the CO adjusted? I have a big ride out of state middle of May and won't have time to rent the tool before I go.. (60deg days, 40deg nights in minnesota) from what I've read, seems to just be an issue with the electric start once it's hot... How concerned should I be about this CO issue? 5) best way to break it in.. Couple of idle/heat cycles (full warm up/full cool down) before riding it? 2strokes need lots of varied rpm durning break in with out any WOT pulls for several hours.. thumpers similar? 6) lastly... Tell me what I don't know . Anything not touched above.. Please throw it at me.. Long term mods for the bike can be another day, just want to focus on the first 20 hours/what ever break-in period is... Awesome site, awesome people, thanks everyone for all the great info I've learned here!!!!
