Okay Ive had it since last September but I am now sick of the kickstart. It usually takes anywhere from 10-20 kicks to start the thing! Compression is around 180psi in each cylinder, plugs show good color with a tan tip and slightly darker around the edges;
All stock machine, no wire splices or modifications. New gas and Honda HP2 oil in the 2 stroke oil tank... what could be causing this? Spark is strong with a blue and white color emitting from the plug.
compression seems to be good. Is that 180 on both cylinders?
Have you pulled the carbs apart and made sure the engine is getting enough fuel?
You can pull the plugs, put a small amount of pre-mix into each cylinder, replace the plugs and try to start it again.
if it starts easier, it's the carbs. if it doesn't then check the ignition system.
Yes, 180psi in top cylinder and 183psi in the bottom cylinder. Tried pre-mix in the summer when I was doing my intial tear down and clean, it did start easier that way, but was only that way.
The bike has about 5800 miles on it, or 9400 kilometers.
Ive worked on and owned 2 strokes my whole life, but due to almost all parts for the NSR being on the other side of the world from the USA, I didnt want to start going into the internals without a good cause.
wouldn't difficult starting indicate an air leak? Perished crank seals perhaps? If its only done 5800 miles over its whole lifetime it may have been sat in storage for a long time which would've upset the crank seals. Including the centre one.
If the other suggestions don't yeild results you should put together a leak down testing kit to check for air leaks.
If you do a forum search you'll be able to find photos and details of the kit i made up for testing my engine. _________________ After years of moaning about immigrants now i am one...
Just on spark plugs, ive found the plugs for nsr's to be a lil dicky. What i mean is, im used to, and its sort of common knowledge that a spark plug should be finger tightened, then just nipped up a lil bit.
However it seems that with these suckers, they need to be tightened up nice, and lets just say, a lil bit more than "nipped up" to get a good, solid seal _________________

standard installation procedure for plugs with proper torque has always worked for me on my NSR's.
The battery is always a good place to check as well, and is part of the ignition system trouble shooting process. These bikes require a good condition, full charged battery to start properly. _________________ Charles Gallant
As Charles said. I find that if mine doesn't start within 5-6 kicks, its time to pull the battery and give it a charge. It then usually starts with the 5-6 kicks. Usually only happens when the bike has been sitting for a bit.
I know mine takes more than a few kicks to start when it has not been run in a while. Makes sense to me the fuel in the bowls has lost its mojo and as you kick and kick and kick you eventually get enough fresh gas to start it.
Mine takes a hundred, or a push start. Ask martin Fitzgibbons. _________________ MC21SP Plaything
