CRF's Only Forums

Hi guys,

maybe some of you can help me out. I have a 2006 CRF450X Supermoto that has been sitting in the shed for about 6-7 years, shame I know.

Last week I said no more, I pulled it out and decided it was time she run again.

Of course the battery was dead, but also it got me thinking: could the bike run if I completely took the battery out and just put some electric tape on the positive and negative wire? Or will I damage some components?

I am probably only going to use the bike like one or twice a year and pulling the battery out, carrying it with me, trickle charge/charge it once a month, and check it every so often just to have it live 5ish years seems like a big pain in the rear.

Can the bike run without it? Or do I need to make some modifications to the electrical wiring?

Also I am getting ready to do some maintenance to the poor bike, seems only fair to her. Here is what I am thinking:

-Carburator cleaning
-Fuel tank filter cleaning
-Air filter check cleaning/replacement
-Spark plug check/replacement

What else do you suggest I do?

Piston, crankshaft and clutch have all been redone just about 20hours before the bike was abandoned, I am not sure about the valves but I think some work was done to them as well.

That's all I can think of.

Thank you!

here is the wiring diagram for those who can tell whether the battery is safe to pull out during engine operation

Welcome to the site !!

It should run without the battery , you just won't have the obvious E-Start , and possibly not enough to run the headlight (the tail light should be fine , but i believe the headlight would draw too much for the lighting coil by itself , but don't quote me on that , as i have never tried to see if the light will work without the battery in place , but the bike itself should run just like the R does without a battery .......

As far as wires , yes i would cover the terminal ends so they do not short on anything , other than that you should be fine , you could always follow the main battery wire to the Starter Relay and unbolt it , so there is no chance of it contacting anything , then just replace it when you decide to replace the battery ....

Everything else you checked should be sufficient , with the exception of the valves , i would check them as well , this will ensure everything is ready to go

Hi Jim,

thanks so much for your answer, it is very much appreciated.

About the the headlight it is not a problem as I was planning on removing it for good.

Regarding the valves to be honest I have never worked on them before so that might be a little tricky for me right now.

When saying check them what do you mean? Just check clearance with a feeler gauge or check the ability of the head to stay pressurized with a pressure gauge? Or are there other ways to check for a valve to be in good working condition?

Thanks again,

dave

By the way awesome website you've got going on here
