My mate who has the BEARs sidecar now wants to build a classic front loading side car to race

We need someone that’s really good with Suzuki GS750 engines

Looking to have x2 cranks ideally lightened and then rebuilt so we have some form of warranty against it.

Can anyone recommend anyone?

Ideally near Sheffield(rider)
Nottingham(passenger)
Bedfordshire(me)

To add,

2valve
1978/79
gs750
4cyclinder
4stroke
Multi piece crank
Web per cylinder
Like a two stroke crank
Lightened, Assembled, balanced, then welded so it can’t rotate
X2 cranks

Roger Upperton in Leeds has been building GS/GSX Suzuki race engines for Donkey's years. Website.

Chris at Grumpy1260 is another experienced Suzuki GS/GSX race engine builder Website.

I would also suggest you have a look through Old Skool Suzuki forum as it's second to none for information on air cooled Suzukis. Here. They also have a racing section which would be worth a look.

One thing to note though, no one will give you a warranty on a 40 + year old crank that's being raced.

No one, absolutely no one. It doesn't have to be 40 yrs old for that.

The race company I used to work for did

The son of another business was taken to court two years after building an engine

The oil filter o ring leaked as he had pinch it on fitting it and they sued and settled out of court £25k in parts

Being taken to court is different to providing a warranty....

Thanks for that, Iv forwarded the links to him

Hopefully one of them can sort it

Covered till its run on a track?

I have known them to, but only when using new parts. A 40 + year old second/third/forty fourth hand crank is a different animal.

White Fence Warranty. Right out of Warranty the second it passes a white Fence!

Wow, how much of a premium did they put on each one to cover claims?

I couldn’t tell you the finances but he had been trading for 30 years and is the second biggest in his field

My Impreza engine was rebuilt by a respected builder, forged pistons, race bearings etc. etc. just short of £3k. Another builder with a good reputation for building high end motors wanted £8k for the same spec.

15 years ago I paid £10k for my cosworth engine rebuild at graham Goode, came with a warranty as well

TTS who built one of my bike engines did the same

Just making dinner thinking about it

I reckon tier 1 supplier agrees warranty terms on the parts supplied and a hefty professional indemnity policy. That'd limit the builder's exposure, but neither would be possible with second hand parts.

Speaking for the Rx8's , Rx7s and other wankel engines. Most rebuilders do offer warrentys to say 2 years or so many miles. Some stipulate oil changes etc and if they rebuild it again themselves they see what has went wrong I imagine.

Rolls-Royed gave a factory warranty on the Merlin.
Warranty was void when the first cannon shell pierced the crankcase.

We used to give a 10 step warranty ...once you had walked 10 steps - no more warranty!!
