Replacement engine install - which rear ISO?

[Coolhands]

Received an engine to put in my ‘72 Combat last night.

The front ISO is stand non-vernier and appears to replaced by the PO. The rear however is obviously older if not original.

Looking for recommendations on a rear ISO. I was planning on just replacing the rubbers on the exhaust and head steady. Talk me out of it, just don’t take too much out of my Tab Classics Alloy tank budget.

Thanks!

You most certainly wanna go vernier with the engine out, otherwise, every time you adjust after will be major work vs minutes.

I agree
Don't forget to lube the adjuster thread on the Vernier or you can end up with more work than the original shim setup

In which case the Iso. buffer rubbers, gaiters and PTFE washers are probably overdue for replacement anyway plus additional shims could be required.

This. It's the rears that are a PITA to adjust. If I was going to update only one, it'd definitely be the rear.

Awesome thanks guys!

Is this engine one that "ran when I pulled it out 12 years ago"?

 

[Coolhands]

Don’t think so, but every if decision I made was reasonable had a perfect list of facts…I’d be driving a beige Honda Accord right?

Toyota Corolla "S" 5-speed Manual and a MK II Commando. It don't get no better than this.

$250 +/- is what the universal verniers used to go for last time I bought a set. Well worth it.

Don't you mean candy apple red Mk2a and red 6 speed Mk5 GTI Golf.

Which Vernier Isolastic has the better rubber, RGM or AN might be the question now.

isolastic replacement suggestions for a 72 interstate

Greetings, I am replacing the isolastics on my 72 interstate. I am in the US and would like recommendations for the best kit, or is it best to buy the individual parts? Thanks for all replies.

Isolastic Rubber Hardness

A little while back I bought a cheap durometer to check the hardness of the tyres on my old bikes. If truth be told, I don’t ride enough and most of my tyres harden with age before they wear out. The durometer has done its job well identifying some old tyres with a hardness of 80 that were...

Hard isolastic rubbers

I picked up my cradle and other bits from Norman White today, he's done a great job of converting to cotter pins and generally refurbishing the whole cradle / swinging arm assembly. He also changed my isolastics as he said "Have you ridden this bike? If so, its a wonder you have any teeth left...

Yes I remember some of those, there was talk of to higher (whatever that word is for rubber hardness) and some increased vibration on one brand.
The original rubber seemed quite soft. (based off the old original single ones I kept)

Well, considering I have a Norton P11 and my car or cruck is a multiport fuel injected gas guzzling 1965 El Camino, I'm the wrong guy to ask. My wife owns the practical stuff.

I have trust issues and am projecting. You'll find out soon enough what you have to work with. Good luck

I’m pretty sure he means a Fireflake Blue “S” and a black Toyota Tundra!

I think he must mean a red1988 Classic Mini plus a '74 MKII Commando Roadster.

The classis Mini was the snizz. First car I ever owned. Literally busted the flimsy stock wheels on the one I had cornering it so hard.

Man, this post went off the rails early. Gotta like it.
