Guys, I've got a fresh 83mm bore that I have been running with a Riva girdled head that has normal 81mm 35cc domes. What is the best approach here? Keep using 81mm domes and do some machining of the outer dome area, or use 84mm domes? For what it's worth, I will be using an ADA girdled...

Guys, I'm just wondering if anyone has any solid info on what the numbers mean that are stamped on the side of the carb bodies on SBN carbs? From what I have read, these numbers correspond to the internal circutry and also the place of origin for the particular carb. I have rung around...

I recently had to replace the lower half of my crank cases with a spare that I had lying around. It's in good condition, but is the older grey instead of black (62t btw). I notice once I have aligned all the bearing stop pins, and put the two halves together, the crank spins very nicely...

I've noticed lately that there is a disturbing trend towards shipping to US adress' only. Now, although I see this as most of you guys looking after each other, is there any other reason why you would choose to do this? I know that some of you have had problems with overseas shipping, but I...

After bolting my engine back together last night, I thought I would check the little oil holes in the top half of the crank case to make sure everything was lined up, even though the guide pins made sure of this. Anyway, I know the two middle bearing don't have oil galleries, and the front...

Guys, I'm in the process of putting my engine back together, but noticed that some of the crank bearing locator pins seems to be flush with the case, does this seem normal? They are not broken off in any way, but I would have thought that even when seated properly, they would be protruding...

Guys, The driveshaft in my 98 SJ seems to be quite out of spec on the coupler end to the point where I can see it moving up and down when I turn it by hand. Although I haven't really noticed any adverse effects (vibration, etc) I'd like to know what's involved in rectumfying this problem...

Hi guys, I recently had a piston in my 701 go on me from running the engine too lean. I had the cylinders bored to 82mm with Pro-x pistons and ported at the same time. After putting the cylinders on, I tested the movement by turning the coupler by hand, and I noticed when each piston is...

Guys, I've just given my bendix a good clean as it has not been engaging properly, and I noticed the flywheel has some worn teeth where the bendix kicks into it. I was wondering if it's possible to remove the ring gear, and turn it over the other way so you have a nice fresh set of teeth...

I bought some reeds off Abe. Although I stuffed around and the transaction took some time on my behalf, Abe sent the parts off and they arrived fast and in top shape. Thanks Abe! Leigh

Guys, I have been using one of the sealed dash mounted 3-way rotary switches for a while, and although it seemed to work flawlessly, I broke it off in the surf last night with my knee when landing a manouvre which I can only describe as a mess. I was thinking of putting one of those metal...

I'm having a bit of a crack at tuning my ski at the moment, and it seems I have most of it pretty good. I do the trolling test where I let the ski idle for about a minute, and then punch it. It doesn't hesitate, or load up, and hits pretty strong, so I think the low speed jet and adjuster...
