I'm going to change my plugs out this weekend, Just wondering which plugs would be the best to put in there! I have sato banzai's on there now and will have a PCIII with a dan kyle map installed this weekend too!

The old reliable NGK's are hard to beat.
Just be sure to replace them with the correct type and hear range.
The ones used on RC51's are the iridium type.
They come pre-gapped from NGK because the tip is very small and could be easily damaged.
So don't bother gapping them.
The iridium tipped plugs aren't cheap, but last a long time.

From the service manual, for temperatures above 41 Deg F.
'00-'06: (MSRP about $12.30 ea.)
NGK IFR9H-11
Denso VK27PRZ11

'00-'01: (MSRP about $7.50 ea.)
NGK FR9BI-11
Denso IK27C11

Thanks man!, your always on top of stuff!

 

[Mrgrn]

yes, OEM

i do every 5k miles and a swap

 

[Hydroboy35th]

I just changed my plugs and put a new battery in, And my bike STILL wont start...its a major disapointment!!

 

[Mrgrn]

is the fule pump priming?

check the kill switch, kick stand etc

 

[Hydroboy35th]

The fuel pump did prime, that kickstand was up(its on a rear stand) in neutral, it sounds like it wants to start but no go. Could it be because its too cold?

 

[olred21]

how old is the fuel, nething over a mo or so is too old, try fresh plugs, fresh fuel and a good battery, if no go you either have a sensor bad or a fuel issue

Well the first thing to check is any fault codes for the ECU.
Jumper the the service connector and turn the key on to see if you get any codes.
Just remember that it stores all the codes, so if there were any problems in the past, it will show those as well if they were cleared.
Count the blinks and we'll see what they result.
A 1.3 second long blink counts as a 10, so for example a long blink and one short blink would equal 11.

Thanks guys!..Strangest thing happend today, my buddy brought over his space heater we heated up the garage and got the bike pretty warm!,..then turned the choke on and it fired up FOR A SECOND, tried it again it and it wouldnt start, tried it again only this time he had the throttle open 1/4 turn it started up slowly but now its all good. I guess it wasnt getting enough air.

Make sure you're idle speed is 1300 RPM when warm and choke in.
If it's too low it may not start properly, since you said if you crack the throttle it did start.

If idle speed is lower than 1300 rpm when warm how do I adjust? can I? What is the knob on the left side fairing, when you pull it the idle goes a tad higher.

The black knob on the left side is the choke.
Look on the right side at about the same position and you'll find a gray knob behind the cowl edge. That's your idle adjuster.

You may need to pop the quick release fastener near it to gain access.

Also, if your engine run switch on the right bar is set to off, the engine will still turn over.
It just won't fire.
Some have had corrosion or broken wires that won't allow the engine to fire.

I agreed to the swap last night thanks to information from you.

Thanks
