650 and 701 cases, the same???

[special fx]

Just wondering if the cases are the same between a 650 and a 701 (61x)?

There are three styles of cases that were used in the SJ over the years.

90 - 93 had 650cc with 6m6 cases & 6m6 cyl, single 44mm carb
94 - 95 had 701cc with 61x cases & 61x cyl, single 44mm carb
96 - 07 have 701cc with 62t cases & 61x cyl, dual 38mm carbs

also, the 760 62t cases which accept the larger sleeves and have 2 pulse fittings

True, but the 760 case style did not come in the SJ. I have this style of cases in my SJ now but I robbed them from an old B2 years ago.

true...its good to know though depending on what engine you are building

Yep, I always hate having to drill a hole for the second pulse line and press in a brass hose barb nipple. I always put a little epoxy around the base to make sure there are no air leaks.

I get rid of the press in barb and drill and tap for scerw in [2] barbs, (1/8 pipe thread) as I have had the barbs come out.

To answer your question, no they are not the same.

(Except for the bottom half....same over all years)

So how different are the 62t cases? I thought all 62ts were the same.

The 760 cases accept 760 sleeves (bored a bit larger) and have a boss for a second pulse fitting.
