My new venture in life

Photos from Twinshock Mx's post 19/04/2026

Some work on this week in the shed.
Xr 600 for a 650 transplant, new wiring loom air/battery box, cr500 front end and finishing off with new rear yss shocks hopefully (if customer is fit from injury) will be riding at martins town.

Yz 400 in for starting issues, spark is great but has more play in the mains the wanted, full strip down to find most bearing sound angry!! And big end gone.

Honda cr 125 76 in for assembly, customer had it at another shop for a year and only assembled the cases but on a quick inspection there is still the old sealant on the surfaces, why would t you remove/clean all before reassembly? So customer has asked for it to be taken apart and checked over.

And finally an engine delivery for an on going conversion.

Happy to help with any inquires.

Hi all
So I have said so many times about how important it is to have a clean air filter, oiled correctly and most of all fitted correctly.

Unfortunately this hasn’t been the case for this customer and has led to an engine removal, head off and some work on the inlet valves as these were coated in the dust.

A simple maintenance action is now going to cost a few quid.😕

Another conversion has come into the workshop this week. Customer has some special parts that he wants on it.
Looking forward to this one and to see another on the track like my first conversion.

More pics on progress to follow.

Another xt 500 motor done this week.
Lot of bits missing inside, wrong bearings fitted the list went on but all done now with a 12-1 comp piston.
It should be a little flyer.

Any rebuilds need doing give me a shout👍

So as I’m messing with Yamaha engines I thought I’d crack on with his new build, full strip, clean, rod, all bearings and seals along with a 540 wiseco 12-1 comp piston, ported big valve head and bottom end cam.

More pics to follow but this will be a good one!!
