Good Day All!

I tried to start my MC21 (bump start only), gas and choke were on, and she started up. I reved motor a little and then turned choke off, she then died. I tried repeatedly bump starting and she would not start again. I checked the plugs and they were very wet. So I know fuel is is getting to cylinders. Any suggestions to getting excess fuel out of motor or just plain getting the bike started?

Thanks All!

You'll need to slap another set of plugs in it!

Leave them out first, and kick the motor over a good few times (or run it up and down if no kickstarter) to vent the cases a little, and then fit the new (i.e. dry) plugs.

Should fire up then. Don't give it any throttle when it first starts up - it's really easy to flood the NSR when you first fire them up.

The original plugs should be OK with a little clean, once they are fully dry. Some people say they should be replaced as they'll never work again, but I've never experienced that myself.

Thanks Andy! I also purchased a new battery and its on a charge right now, just to rule out that it wasn't an electrical problem, I will post up when I get bike started(optimistic).

If you think it`s flooded.
The way to start it is to turn off the fuel tap, turn off the choke & open the throttle fully to let in the maximum amount of air. Then try to start it.
It should fire up fairly quickly, once it`s running you should be able to turn the fuel back on.

They're a pig with wet plugs though!

I don`t doubt it!
What I posted is just a technique for starting a flooded engine.
If the plugs are oiled/fouled then it`s a different matter.
If it`s just flooding, then this method should get the engine running.

A lighter/match will solve the problem. just kidding.

Hi Andy, my nsr is still not starting up. I checked for spark and nothing. Basically, bike is push start only and on the rear wheel stand I had my wife roll rear wheel in 2nd gear switched to run, pulled plug and set on fr head attached to plug connector and no spark at all. HELP! what can this mean?

1) Definitely getting fuel, carbs cleaned and set as per usual
2) Battery charged to 13.2 on volt meter
3) Dry/known working spark plugs used for check
4) Gas (premix 32/1 C12 & Motul800) in tank
5) Fuel flowing through petcock
6) Went through all electrical to be sure nothing was crimped or disconnected

Hmmm, is there something I'm missing? could it be the regulator, stator, HRC Box, PGMIII or ??? Any and all feedback welcomed. NSR gods, please come to my rescue, I want to do the last track day of the year!

Randy - BTW here's a pic of the nsr after last race

sounds to me like the pgm mite be dead mate do the rc valves reset ?

just thinking on has it still got the sidestand switch?

Fenton, the rc valves were not resetting, how can I tell if the PGM is dead ?

I have another PGMIII that I can try on the bike as well.

Wow, this site is amazing! Alot of good replies and feedback to help w/the troubleshooting...in a nutshell, fenton suggested that my PGMIII may be dead(I didn't even check, let alone know what process it would involve as I am electrically inept when it comes to the nsr. However, I did notice that my old battery was dead or barely holding a charge @ 3.5 v, So, Interstate Batteries replaced the old one w/brand new one and charged it up w/13.5 v on volt meter. Immediately went home to check for spark and low and behold we've got spark, bump started the bike w/in 10ft(whooo, what a relief, as I nearly ran around the block trying to bump it) After Idiling the bike for a minute or so I started blipping the throttle 3k to 4k, 3k to 4k, bike got up to 60c w/in 5-6 minutes and just noticed a very healthy reving to 6/7k. Very excited to do the trackday this weekend, seems like the bike is running better than it has all season racing it.

Moral of the story: 1) Always check voltage on battery 2) Fully charge if needed 3) Keep trickle charge when not in use 4) If battery is neglected, could ruin PGMIII (good thing for having a spare that works!!! (BTW- can faulty PGMIII be serviced and/or repaired?) 5) Trust in the NSRWORLD.COM Members, as they are so coooool!

Thanks again Andy, Fenton, Chester, Stephen aaand for all tech help this season! You brits have helped me w/my first season on the MC21 and have earned 7 Podiums, couple of 3rds, few 2nds and a great 1st @ Willow Spgs, racing w/ a fleet of April RS250 Cup Bikes (for those who have never raced against the cup bikes, they are fast and nimble; however, no match for a fully built/deristricted nsr.

BEFORE you even think about trying another PGM on the bike you need to find out what might have caused your's to burn out.
The most likely cause of a PGM to burn out is sticking power valves as they get coked up.
I have a MC21 that burned out the PGM as one of the power valves was cabled up wrong so it would close when it should be opening but it still runs with the burned out PGM but the servo motor wont work whick is due to the part of the PGM that operate's the servo motor being fried.

How do I check , to see if they reset ?

Hmmm, thought I was in the clear?!?!?!

Unplug the TPS and turn the ignition on, the valves should sweep to the set position.

Once the valves are set up reconnect the TPS and away you go.
