  1. If your dizzy mech weights are sticking, youll need to strip that fucker down. If you pop the cap, you should be able to turn the rotor approx a quarter turn, and have it spring back again. In a perfect world, each time tge pounts are adjusted, a drop of oil should be placed under the rotor. This dribbles down and keeps the mechanical advance arms lubricated. (Tbh, i never knew about this either)  

    The other way to check it it to check the timing at idle with a timing light, (vac hose off, and plugged)  give her a gradual rev up to 3000. See if the timing mark advances as you do. (Between 1800-3000 approx)

    classy eh, everything  changes  inside except  the seat mounts, they on cert plate, awesome  gear change too, a foot of lateral  movement & nearly a foot fore & aft lolol

    Assuming its a nissan FS5w71b gearbox, there will be bushes on the shifter. If these disintergrate, the shifter will get sloppier than Al's mum.

  3. Question for those who have played with rust removal via electrolosis.

    Do you thing it would work for an engine bore that was rusty A.F/seized?

    Fill the cylinder with washing soda enhanced water, susoend the cathode in the cylinder, and hook up tge block and cathode to a 180A arc welder. 

    Surely that would boil the rust off the bore walls quick snap?

    Got a big, ugly in line 6 that sat with the plugs out for a loooong time. Havent pulled the head yet. But its seized hard enough that an attempt to tow it free blew the clutch.  Worth noting its big, heavy and ugly enough that removing the engine will be an ordeal. (Let along handling it once its out)

    Engine may make more power but that bike is probably a week old and already chrome is coming off and frame is cracked in 10 places and engine makes a loud ticking noise and its on its 3rd seat cover and some how forks are full of water and gear change spline has rounded off and the ignition fell apart

    Stop it, youre making me hard!

    Speed monitoring in the name of road to zero, speed is the only thing anyone ever should be thinking of 

    Distance you travel ("you could have walked or bicycled")

    Driving behaviors,  excessive acceleration 

    Travelling somewhere that it's encouraged not to ie city center at x time 

    But wsit, theres more!

    Oh you drive a supercharged big block? (I wish i did) 

    Your electronic rucs are three times the price too......

  6. Remember way way back i shared with you a page with some "rule of thumb" formulas?

    And you ran the sums, and they said cast piston go BOOM?

    Is there any galling on whats left of the the pin boss? The last motor i destructively tested to failure had nasty galling on the gudgeon pins. And another piston was stiff on its pin too. Datsun motor go bang too.

  7. Regarding your engine woes,

    there was a clever fellow who used to post on a forum which i used to frequent.

    He once reckoned that these motors made more power with a smaller oversize due to bore wall deflection. Given youre going to be forcing it down it its throat, (and you gotta build a new engine anyway) that might be a consoderation when selecting your replacement block.
