Hey,

A friend of mine was tellin me about a drag 250r 3 wheeler he built back in 89. He had it bored to 330, 2 carbs,ran on nirtomethane,had a ceramic topped piston,an almost unbreakable rod.port and polish job,and it had nitrous. they said it was fast and i mean fast.

i just wanna know what happend to helm and son??? i never heard of them they got out of buisness???
i know they were in cali or arizona. If they are still in biz got a site??? howbout a parts catalog????


Thanks In Advance

Later Ryan

 

That's a good question I use to run a lot of their stuff back in the day myself. I use to flat track a 185S with a bunch of their stuff on it. At least I ran that until the 350X and 250Rs started getting popular. Seems like around 1980 or so.

 

I used to import a lot of their stuff into Australia years ago. I think there was a fire in the mid eighties that closed them up. I visited their workshop in Phoenix in 1982 and was very impressed. I am still using old stock Helm and Son strokers in my hopped up 110's and 200's.

 

anyone have any helm and sons 61.25 piston sets? atc90
if so please let me know
needs to fit 61mm stroker short rod
