2006 er will not start

[honda4life72]

ok my buddy has a 2006 450er and it wont start. it will turn over plenty fast (new batt) but will not start. u can roll it 10 feet and it will fire right up. we recently had the frame powdercoated and it would start then but now it wont. help? how is the selinoid spose to be hooked up. i know the selinod is good because i can jump the power acrose it and it still wont start.

r his grounds good

[honda4life72]

where should there be ground wires?

[coryatver]

he is saying you need to grind power coat off between frame/ subframe and where coil and ground wires touch.

[honda4life72]

yea we done that already

[honda4life72]

done that any other ideas?

[blacknblue#2]

all grounds are good or it wouldnt be turning over. Sounds to me like the the valves need adjusted or the decompressor is out of adjustment. What cam is he running and when were the valves last adjusted

[honda4life72]

i was thinking the valves needed adjusting also. but it will roll start and crank right up.

Everyone always thinks its the valves. If it will roll start then you need to trace the wiring from the battery to the starter and everything that goes with the starting system. Could be the valves but check the most common first the wiring.

"ok my buddy has a 2006 450er and it wont start. it will turn over plenty fast".....it will turn over with the starter so that wiring is fine............."u can roll it 10 feet and it will fire right up". you can roll start it so its gettin fire, meaning that wiring is fine?? what other wiring could it be??????

Yes check the valves and decompressor for sure. If its losing any compression then the starter will never turn the motor fast enough to start but rolling it will. Ive been there plenty. If it will start by rolling it and the starter will turn it over then that eliminates all chances of wiring cause you are getting fire and fuel if it will run.

wat should the specs be for the decompressor and valves? stock motor

[Scro]

I've always used

.004-.006 intake
.008-.010 exhaust
decompressor, .007 + right side exhaust

[rollie]

Does the starter spin, but not engage? the same thing happened to me and it was the starter clutch

[450rJam]

intakes are probably tight and check decomp

use compression tester and set at 65 psi

[honda4life72]

yep intakes were wayyyyyy out of spec. like i told him three months ago it felt like it needed them adjusted. but she runs like a champ now:macho

Glad we could help ya out!! :macho
