    timing between 1/4 and 2/3 is way off

    Thanks for the reply Unfocused, If it was a small adjustment i would not have bothered writing a post. I guess i have to examine the governor assembly for accuracy and 180degree spacing. I am surprised; it seems like a solid part with some slight clearance between the weights and the rotor. No...

    clutchpack thickness clutch release maxed out

    After installing a Vesrah clutch pack on my 750 8V the clutch release bolt has to be turned in so far the nut baraly fits on. I could try and slip the clutch a lot to thin the plates ;-) Anyone has the same experience with fat clutch plates ?

    smoothbores bog, air screws no effect

    I have cut back a rectangular shape and have doubled the size of the intake. Still want to make a some sort of intake box guard and some dampening material, propably PPI 10/20 The battery box is in the way so i might solve that first.

    smoothbores bog, air screws no effect

    Great advice, I will cut the whole lower part of the back side and maybe fit a splash guard or custom metal ?snorkel? I already have a K&N filter installed. Thanks Zed !

    smoothbores bog, air screws no effect

    Anyone have experience with enlarging the air intake on a stock airbox ? I could cut a maximal intake and try to shield of with, gaffer tape for instance, to try to work out the best intake size. But i am curious if someone else has had good results and how much was cut ?

    smoothbores bog, air screws no effect

    I got up and drilled 54mm. holes in the lower part of some spare side covers. It makes a big difference; the bog is almost gone and the engine breathes much better. Now i am going to find out if i can make a larger inlet in the back, find a way to muffle the intakesound.

    smoothbores bog, air screws no effect

    Thanks Zed, This explains a lot; i will go experimenting with the airbox tommorrow. I like the original airbox for holding the carbs in place and giving a sonore sound when driving down town. I will try to find a way to make it work. Maybe something with extra side vents And i will look into the...

It starts to slip in the higher rev?s. about 6K I have already changed the oil, the clutch springs (oem) and measured the plates; they are in spec. I also cleaned the plates and scuffed...

    making a colortune

    I have thought about brass/copper but was afraid it might get too hot in the head for a different metal. They might use a mixture of metals and i know nothing about melting points. So i thought iron was the safe way to go. My carbs are way to rich so i first try to get them leaner and see if the...

    The carbs are VM slide carbs. The nail is a common iron nail, i have not thought about impedance.

    https://www.youtube.com/watch?v=4T1FzNnIXe0 it is evening here, so better visible. I can?t seem to get the blue color. Maybe i need a smaller set of pilots.

    making a colortune

    Good advice ! I am wearing glasses so that is a bit of protection. Chuck is right; it is hard to see specially in the sunlight. But under a blanket with a fan for the heat it works. And because i won?t use it often it saves me some cash for every day tools.

    making a colortune

    Well; the original one costs 117 dollar. The nail costs me 7 cent and an old spark plug. It?s worth a risk to me.

    making a colortune

    a nail for a pin welded to a 4mm. thread and taped to the top. At the bottom end i have a small piece of tape (folded inside out) to stick the nail to the electrode to keep it centered. After that i keep the plug upside down, stick it to a stand with tape and fill it with a seringe with epoxy.
