Hi Everybody.

 

So I have a 2013 YZ450F - It has stage 2 cams, reworked head (porting), weighted fly wheel, WR Gear box  and an akrapovic titanium pipe.

 

Just had the bike shimmed.

 

I love this bike, but I do battle to start her unless I have the fast idle on, this is particlulary difficult when I stall on a massive slope :p

 

Would really appreciate some feedback on how fellow riders get this right!

If it is any consolation, my friend has the same problem.   We are looking into a few things.

What is the idle set to when its hot? Should be about 2k to 2100, mine is ridiculous to start if i have it set to 1700 to 1800 when its hot. And make sure it is on tdc when you try to kick it or it wont start easily

If you stall it you definitely want to put it in neutral as step 1.  Too much clutch drag on these bikes.  

 

Then make sure you find TDC and give it one good kick.  Don't just start flailing away at it.  If it doesn't start, find TDC again and repeat.  Just be patient with it and it will start.  I learned that you save much more time and effort if you slow down, and follow the steps.  

 

Set the idle around 2K and you should be fine, but i've never really noticed on mine that it makes that much of a difference as long as it's not crazy slow.  

 

Also, what map do you have in it?  When I changed mine from the stock map to the woods map it made a pretty good difference on the starting.  Mine is a 2011 so it may be slightly different, but it did seem to help.
