Hello! I want to ask how the large holes in the cooling fins work. I often see such tuning, but no one can explain the very principle of their work. If you make a grid of holes with a diameter equal to the thickness of the fin, then this increases the cooling area, and how are holes of such a large diameter useful?
Is the nearside crank oil seal in back to front here? Spring or inner side should face any oil. Other side with generator should look like this side though, as no oil there.
Carbs are restricted by our club rules to Bored out original BVF carbs or Mikuni 32 VM or 34 VM. This is to conform with the club technical regulations bmzrc.net/wp-content/uploads/2017/02/BMZRC-Technical-Regulations-2017-1.pdf
Are folk still rebuilding these engines? I have a road going ETZ and the engine needs a complete rebuild. I have a go myself but understand you have to get the clutch tightened particular well else it’ll spin on the crank and bugger it up. Any contacts much appreciated!
@@BikingChap Yes, you have to torque up the clutch bolt. Here's the workshop manual if you fancy giving it a go yourself mzriders.files.wordpress.com/2017/04/mzmanual.pdf In the UK there are quite a few places to go. Depends where you are.

I think it's simply to save weight.
Nice work🎉

I need to buy a cylinder with a piston and a cover of these live race in the United States as I can buy.
What type of piston is this?
It is a piston for a Suzuki TS 250. some people use Wossner or Wiseco pistons for this bike.
How much power it does? Any dyno figures?
This engine produces 26bhp. Others with this level of tune can make around 28bhp. With gearing I run it has a top speed of around 105mph
Nice! What carburator it uses?

@@stimpetta Kmh, nicht Meilen.
I once found a fantastic site on this subject online, where the claim was up to around 45 hp. No reason it's not still to be found.
What piston is this?Where can I find it?
This piston is from Tony Holmshaw. Other suppliers are Wiesco and Wossner (Suzuki TS 250 piston)
Piston are either custom made forged items or Suzuki TS 250 forged pistons made by Wiesco or Wossner
