The max power and torque are quite high up. We will have to rethink prop pitch

I just use grining wax on my carbides, do a cut and the tool will heat up then put it on the wax. The was will melt and put a nice coat on your tool. Make sure your carbide is sharp and so it cuts and doesnt just wear its way through the metal

You cant grind alloy only cut it. It will load a wheel in one second flat. Get a sanding flapper wheel that will work. They will rip the alloy to shreds in no time. I use them all the time, the sand paper cuts the grinding wheel grinds (of course lol)

gp1200 engine

That should not happen. Fuel takes x amount of time to burn. If you have it kicking back on the starter you have another issue. Bad stator alignment or something If both engines were cranking at the same speed and there was not a physical issue with the first ie low compression, bad combustion...

I'm saying that maybe the issue. Think about this a stock ignition will run it but an aftermarket will not. What's wrong with this picture

Huh ? Some one is telling your porkies if thEy say it will not work on a stroker.It may not have the power required to fire the plug under the load but that because of a weak ignition not a problem of having a stroker.

Crankshaft degrees are crankshaft degrees. At tdc the pistion is still at the top. The time taken at 7000rpm to turn 30 degrees of crankshaft rotation does not change with a stroker. It's just the distance the pistion moves that's different. The cdi does not know where the pistion is only...

The cdi does not know how big the engine is. it knows rpm and degrees before tdc

Jets will still allow it to start so will the pop off. Change coil but I think you have an ignition issue. Timing or weak. I had this sort of issue with my epic. I changed everything the only thing that fixed it was an msd

Its sitting in the shed It will be happening this winter, I have been building a triple blaster

Yup I understand that about the yamaha ignitions. What your talking about on the kawasaki is a dc cdi where it fires off a pickup like most motorbikes do. What rpm do the yamahas run put on spark. I haven't seen this as an issue at any stage to date. The total loss is a good upgrade due to...

Which is great for an engine with an inadequate ignition system. Our engines are not that engine. We have a bad curve not a weak ignition. It may be better for cold starting however. Then again I have never seen a correctly tuned yamaha that doesn't leap into life as soon as you hit that button

There is no gain firing a mother spark 10 degrees after the first unless the first one did not do its job correctly.

I have been using jb weld for ages, I have not had any come off other than when I had a guy let the engine sit in water for a month. It corroded under the jbweld and lifted it off. Not really a fault of the jbweld. I understand what you are saying about the loctite getting soft but its not...

Would that someone be in Australia

I did print a hull. It was only 10cm long, not sure it would be of much use to anyone other than a test model to check your shape

Because alot of fagots couldnt ride them. The people that can ride still own them

If the pulse coil runs of the ground only then how do you complete the circuit with the red wire disconected

800cc limit, Crank and stroke maybe changed
