It's not ideal, but as long as the barrel and head match, it will be OK. I.e., you can run one "R" barrel/head and one "SP" barrel/head. Actually, we're rebuilding an SP motor for a client right now, that was delivered in that configuration.

The heads on this particular motor are damaged, one severely, so we're fitting VHMs and machining the inserts to the correct combustion chamber volume/squish. Once the client sources another good, matching SP barrel, we'll then provide a new VHM insert to keep everything in spec.

We do NSR/RS crank rebuilds, and are part of a Honda Main Dealer franchise now, so our OEM parts price list comes straight off the Honda system, matching Fowlers/Lings/DSS etc. list prices. Our cranks may be a little more expensive than others, but judging by what we've seen with our own eyes, they are far better! Cool



PM me if you would like a basic costing of rebuild parts, as I've only just done a quote so have an Excel sheet set up.

I've used SEP and while they are ok, I think I'd trust my NSR crank (if I had one) to the guys at Performance Engineering, who have a huge amount of NSR experience and offer so much advice and support through this forum. When my next RS (non rebuildable and unobtainium) crank is up to mileage, these guys are top of my list to speak to.

Just my tuppence worth Smile

Some of the RGV forum swear by them, but I had an RGV250L crank done by them and it was crap! A mate had similar issues with a GT550 years ago.

Luckily I bought 2 new NSR cranks a couple of years ago, so I'm good for some time yet. The RS rarely gets a chance to stretch its legs now, because I simply can't fit onto it!

Hmmm... recurrent theme, I'm thinking.

Had a Mk1 RGV crank done in a previous life, that rattled my fillings out!

Each to their own, but I'm glad we had Brian at BGC Performance to do ours until he passed away, and mentor Stephen.
