This bugger here is the problem 

Take out neutral bulb and missfire goes away

There was a guy on one of the auckland rides that had a similar bike, and I remember talking to him about that speed limit thing in the speedo as well

You really don't want to seize a Nikasil cylinder, game over if you do.

Ugh. Too true. RIP my NSR cylinders.

The speedo is completely analog no micro switch or anything that triggers a cut. The kickstand switch is part of some safety circuit thats linked into the neutral switch so it would only fire if you kicked it over in neutral or with the stand up. The switch for the kickstand is a common Suzuki  failure according to mr google.

Im guessing that at around 55 the vibrations of 2t lyfe vibrate the switch enough to complete the circuit and cause a gay missfire

A+ good figuring out, what an odd balls problem. Excited for this thing

[Truenotch]

This thing is sweet! Thanks for letting me ride it today.

That clean spot on the piston top is where its been trying to impersonate a Toyota M series.

RIP NIKASIL barrel

[Yowzer]

Yikes that didn't last long

[HighLUX]

Not with an air leak effectively leaning it out and small engine small tolerances she got too hot around lunchtime when the ambient temp really got hot

Good excuse to get the motor out and do crank seals etc, they could of gone hard when it sat for so long with no kms done to even soften them up. Trying to eliminate all possible sources of an air leak

Replacement cylinder kit ordered off Ebay and already on its way thanks to efficient German shipping. Hopefully it gets here by the 24th. 

Got the engine out of the frame for a strip down to do all gaskets and seals

Chair boye, you know it. Shouldn't be a problem, unless they are super silly sizes.

[Vintage Grumble]

/text me sizes you need.

[HighLUX]

Will do once I get magneto off etc

[HighLUX]

Cylinder kit turned up yesterday so its rinse and repeat time. Tomorrow nights mission is get the crank seals out

 

[HighLUX]

So doing the crank case seals ended up being a cunt of a job that required the case to be split.

Currently assembling the case again after figuring out how the shift drum and gear sets go back together.

[HighLUX]

Got the case sealed up with Yamabond 4 and fresh oil in the gearbox. No leaks and shifted through the gears perfectly so I must of got everything back together right.

Been slowly chipping away at things like getting the piston/barrel back on, used copper gasket spray on the headgasket then remembered I had a torque wrench that started at 10nm. Got pedantic and 3 stage torqued the head down to 15nm.

After waiting all week for the plastic bush that connects the 2T pump to the throttle cable and a chat to a bike mechanic I decided to go premix so you know its always getting enough oil to keep things happy. Left all the pump intact with a ball bearing in the end of the feed line incase I wanna go back to factory setup some time.

Bunged the biggest jet I have in the carb (130mj) and got it fitted up again this morning. Started 2nd kick which was a good sign then settled into a nice smokey idle burning out all the 2T oil used in the assembly.

Took it for a quiet 20min ride to run it in and get some heat into everything. Its running riiiiiiich but mint. Gotta get some new plugs so I can do a proper plug chop and start dropping the jet size back to maximum braaaaps. Will retorque the head in the morning then buy some spark plugs. 15 tooth front sprocket should be here on Monday after taking the long way from Italy via Australia to get here. Will be interesting to see the top speed with it fitted, im hoping it will give it enough legs to sit on 75-80kph without having to ride at WOT everywhere

Added more brap to the stable in the form of a 2007ish PW80

 

Pretty rough looking but runs sweet enough for how cheap it was.

Will get a new plastics kit/decals and basic tidy up to give to the kids at Christmas time so they can learn the allure of 2T life
