Having a cable trunnion on the throttle cable on that end is weird. I've never seen that before.

Large carb setups will most likely use that cable setup…

I feel it's the easiest to adjust and get the exact length and tension you want.

Wouldn't that go at the carb end and not in the hole of the throttle pulley? I've always only seen a round cast head with the cable end embedded in it.

Goes on the throttle end.

With the cast cable, you can't cut to length (well you can, but it's a bit of work…)

With the cable in your image, the inner and outer are fixed pretty much.

With the trunnion, some folks solder the cable too for extra strength.

Interesting. On my small frame, I use a gear cable with a small trunnion at the carb. The cast end goes in the pulley hole in the headset.

The GS/SS are fixed length inner and outer with a larger cast end for the pulley and a small cast end for the carb end.

I use a pinch nut in the same basic setup, but with a larger pulley on both my smallie and my GL. You need the larger radius to get enough throw for the big carbs, and as others noted, it's the only way to get any meaningful adjustment.

Also, on the largeframe, it's an extra-long throttle cable so it'll reach.

I just prefer to use the cables that have a cast small nipple on the carb side. On a smallie SHB it's ok to use big clamp nipple, but on "real" carbs there is no room for it.

But boy oh boy. Goodies are finally here
Crank and something to mount on both ends.

Meanwhile on the budget 200 side. Got the Polinibox to replace the stock one.


Is it just me and my old Malossi that has the exhaust stub slightly angled more towards outside or is it a common thing?


Even pushing by hand is not enough to line up the mounting holes.


Introduced the exhaust to my angle grinder and took a wedge out to get the box high enough. Now it's just matter of welding it back together.


I'll likely have to also fit a slimmer spring for the cemter stand return...

Spring is not the only problem. The support of center stand is also fouling on the exhaust. Maybe it's just time to order that side stand.


Put on couple tacks, removed and laid some bead to fill the cut. Threw the box back in and checked that there is no tension before tightening the clamp.

You could move the center stand to forward of that rib with an MRP bracket (SIP) or make your own. More stable with the stand at that position as well.


Included a side stand on mine.

I made some brackets like this for my GL, as well. Works great.

It doesn't attach to the frame there. The original center stand bolts hold the bracket. Stand and spring to bracket only.

I went the easy route and simply bought the MRP bracket for my Allstate. You can scroll to page 4 to see it in the thread below...

Nice! Did you drill extra holes for the mount?

For the little stainless "exhaust spring hanger" bracket? No, both the MRP plate and the SIP bracket both had multiple holes predrilled in them. I did have to oval out a hole a little bit so that they would line up though.
