B44 engineering item and a Piston recommendations?

Post by craigacc » Fri Jun 12, 2020 12:10 pm

HI all,

1. Looking for recommendations for an engineering business in the South West of the UK which can fit an Alpha big end and balance the crank on my B44. I've been using a business in eastern England, but it's a heck of trip up and down.

2. Are there any views on Italian Gandini pistons? Just acquired a new one for the B44 (which I can return), but it's rather 'trick' Pic attached. Are these any good? Positives/negatives

3. Fork legs. Older type with the oil seal holder thread needing a clean up at the top of the slider. Who can do this?

Thanks! Your advice as always, will be gratefully received.

Craig.

This may be 5 years old, but Hickey's are still around and RTS seems to have a good reputation round these parts. I'm not sure if Gary Bowden is still going as I heard he was ill.

viewtopic.php?t=6167

"You could also try Colin Hickey, Hickey Racing Services in Newton Abbot on 01626 360803, Roger Taylor at RTS Racing between Gloucester and Tewkesbury on 01452 840 438 or Gary and Stuart Bowden in Bristol on 0117 969 3355"

Once Classic scrambles start again, go and watch, see who's B44 seems best ask around and track down the guy's van and ask him who he uses...

Cheers

Ian

Hi Ian

Thanks for providing that link to the thread that Stan contributed to, as I was searching for it the other day and couldn't find it :thumb <1011

Back in the 70's and 80's a company called Basset Down near Newbury advertised their crank balancing services in the motorcycle press, not exactly near Cornwall but maybe worth a shot. Their website says they can balance any crank including single cylinder and they mention engine rebuilds on their website so presumably, they can change a big end and balance the crank, see This Link

Regarding the Gandini piston, I believe the general consensus is that they are heavier but nothing especially wrong with them. The best piston available is probably the one sold by E&V engineering in the US, see This Link

I will second Ian's recommendation for Hickie Racing Services. Brilliant engineer, and has built some cracking bikes over the years. Always there to help and prices are very reasonable. Many riders in the SW ride Hickie built machines.
Colin has helped me on many occasions.

Thanks all,
Very helpful and I'll try these recommendations.

Any thoughts on the thread clean up for the fork slider I mentioned? It's actually from a BSA RGS.

Hi Craig

Depends how bad the thread is. You could try a 'thread restoring file', plenty on ebay etc. just need to check the thread you have and count the tpi (teeth per inch) so that you purchase the appropriate file. Another way may be to turn a knackered fork oil seal holder into a die by cutting grooves at right angles to the thread so that as you screw it onto the fork bottom it cuts, although in practice it will act more like a 'thread chaser'. If its a common problem you may find a specialist repairer who keeps the appropriate tool in stock to repair the thread
