Re: Getting steel ring out of break disk

The drilling oversize is not necessary if the three holes are cleaned up along with the pins & reassembled with copper type grease. Likewise, the anti-rattle circlip does precisely what it should. In fact, any spare discs that I have are those modified by well intentioned previous owners. The reason...

Re: Dellorto 34 VHSB

The atomisers that I unserstand find use in TS engines are DP, not DQ as used in piston ported barrels. DP266 would be a good starting point.

As for needle, K30 would be a good basis on which to start.

Re: Dellorto 34 VHSB

I have just built a TS1 (70 x 60) from a knackered engine (66 x 60) that came with the same carburettor. I expect the original jetting will not be far off when I fit it again, but the atomiser & needle are very worn. I think the VHSB/C range are OKeh as they are a two stroke carb, but although very ...

Re: Found a phbl sized foam filter for restricted room

Any feedback on these filters from those that were going to get one to try?

Do they work well enough to be non restrictive?

Any issues with hot starting (due to flooding) from fans of the PH range?

Re: Cheap 5/6 plate clutch

As if to prove myself wrong, I managed to squeeze six Camlam plates & steels into standard components yesterday (the crownwheel was de-rivetted & the slots deepened prior to reassembly with M5 button head socket screws tapped into the sprocket part) The only significant modification was to recess a ...

Re: ? About wrist pin shims vs wider small end bearing

I've always fitted the widest small end bearing that will fit. That said, I don't have an issue with proper shims. A crankshaft will work without shims either side of the big end bearing, but not really preferable. I have seen overheated con rod sides as the result, so if the float can be practicall...

Re: Cheap 5/6 plate clutch

With any clutch requiring additional plates, there are compromises if attempting to use standard components & five is the greatest practicable maximum. Most users will require the strongest spring set that will fit, but they shouldn't be allowed to get coilbound & although that may be obvious, there...

Re: Mugello 240 ??

For those that may be unaware, a small tailpipe on an exhaust is an easy way to increase the torque of an engine, but @ a cost. Particularly on a 200cc plus engine, with any guts, I would always use a minimum of one inch (25 mm) bore bleed to an exhaust for peace of mind & reliability. Despite such ...

Re: Impurities or alloys that complicate case or headset welding?

Die casting of alloys usually includes metals that will improve the finished result from the aspect of appearance & performance. It's not an easy process for the foundry to get spot on. As a youth, struggling to earn money in a summer holiday job, I inspected (keg) beer barrel handles, one of the ch...
