My first 450, what do I need to know?
Hi guys, I just picked up a 2006 450, what are the main things I need to look at? I picked this up in trade not running. I think I can repair it without rebuilding the engine. Kid said it was running, he parked it and went to start it next season and it wouldn't start. Who knows... people lie. So, I went and checked it out and wanted to turn the motor over just to make sure it had compression and there wasn't a valve train issue and the motor wont turn over. Starter turns on but the motor doesn't turn over. reading on some other pages, people said the 1 way bearing or starter gear assembly in backwards? any thoughts? What do I look at next? I know there was an oil issue with the 04-06's. Anything I should look for? I plan to pull the valve cover and check the valve clearance and while I am in there I will inspect the cam races. What else to look for?
What is a good oil to run in these? does a good synthetic help with the oil issues? I plan to check to see if this has the 07 oil mod done. Is there a way to ID if the oil pump was replaced?
Along with this unit I got 2 heads. Both have bad cam races. Who is the best at refurbing these heads? and, is it worth it? I got them for free so if I have them done, can I sell them? What are they worth? I also have a good OEM cylinder. looks nikasyl..... worth sending out for refurb? I hate scraping parts if they can be used.....
I also have a set of stock cams so I assume it has aftermarkets installed. guy I got it from mentioned it but was kinda cluless. most of the spare parts he had came from his cousin that used to ride these. How do I tell if this has a set of Hot Cams? reference picture?
It has an FMF exhaust, not sure if its jetted correctly so that is something else I want to look at. I am north of Chicago, I think we are only 400 feet above sea level. Any baseline jetting ideas?
