I think a pair of new front boots wouldn't go a miss either You are correct Lee, only just legal, so some new Blockleys will be fitted before not too long  Think that’s an optimistic analysis, Ricardo. You could stand as an MP in the upcoming election...... 😊

Impressive exhausts Ricardo. If they sound half as good as they look they will be a good buy. I must admit, I also looked at the tyres more than the exhausts in the photo  . Not going to try a set of Michelin Commander II for the full "racy M3W" image then?

At that point I added the roller rocker upgrade and found it worthwhile. So you have exhaust and roller rockers and no high lift cams? Were the rockers a noticeable upgrade.?

I have fitted high lift cams, part of Morgan stage 2 upgrade, type 968 from memory.
The roller rockers were a distinct upgrade after this.

The MMC Stage 2 is cams, throttle bodies and an ECU reflash; the KH equivalent offers combinations of larger headers, rockers, cams, injectors and throttle bodies plus custom tuning; G56 is cams.

After speaking with Stuart at Krazyhorse, i was surprised when he said that the larger throttle bodies made no difference even on the Dyno.
They come in 52mm 58mm and 66mm.
All they do is reduce icing. So if your 3 wheeler suffers from this. It may help.
Cams i think from memory are 545 569 and 618. 618s are an interference fit. With the 618s you may need the 650 spring set because of the higher lift.
Roller rockers do not make a large difference on Stage 2 or 1 engines. Stage 3 and above get a boost from them.
Somewhere i have the S&S parts list. When i find it i`ll make it available.

John, the interference fit valves would sure be off my Christmas List.

Maybe i should have said that the 618s are not a non-interference, drop the cam belt drop the pistons.

Not my experience on both counts
