Well, it hasn't bounced from the facebook adress- yet. Thanks again
Ah, thank you. Not being on facebook I'd never seen that one. I'll give it a try.
Thanks for that. I've messaged the second outfit. The email for Classic motorcycle fiberglass is the one which failed for me
Might be better known as Moto Tumbi In Tumbi Umbi on NSW central coast. Maybe affected by flooding ?
Has anyone had recent contact with this firm ? The email adress on their website doesn't work - at least from NZ. I'm interested in ordering seat,...
You ask how close a fit the big ends should be. Aim for 1.5 - 1.6 thou. that is .0015in to .0016in clearance. Plastigage is probably the easiest...
Just like bronze welding. Big soft flame. The filler rod melts at a lower temp than bronze Not a lot of heat needed - but the cam lobe needs to be...
Mike, going back a ways, the first plenum chamber I made for the blown 500 Kawa was in 2mm alloy. It was destroyed by the inlet pulsations of the...
Traditionally, reverse flushing is the starting point. High pressure water in via the usual outlet. If there's a radiator repair shop in your...
Main thing for real supercharging is "no overlap" Sorry, GG you've poked the bear. that's bullshit. At high boost pressures an old way of...
Taking a few thou off the base circle and hand blending it into the ramps was feasible when we were all racing singles. If you dropped a valve you...
Cam design has always been a can of worms. Old days it was calculate the lift/acceleration rate per degree of cam rotation. And if you had enough...
No it was pretty cheap actually. The new profile was cut out of the existing one and the difference in base circle was accomodated with thicker...
Normally on a bucket and shim OHC setup, the stem centerline will coincide with the cam centerline. The bucket bore centerline may not. An offset...
A couple of points arising...Plasticene is temp sensitive. Cool the head and the plasticene and it'll stay firm enough to cut and measure....
Not an uncommon development in an engine design which has been around for a while. Longer rods are a help in reducing angular friction if you're...
The general convention with coils is that the green should go to the larger of the coil terminals - if there's a size difference. If they are the...
The longer rods are matched to shorter pistons. Block height is identical. Other than the valve stem OD the head geometry is also identical.
Took the crank off the guy who was going to do it. Huge backlog of work as he's not been well. Took it to another long time machining source who...
If nothing turns up there is a fix which I've used. There's a eutectic overlay which is applied to cam lobes by gas welding. I got a part stick...
