Sleeve vs Plating (how much do you lose)

(1/3) > >>

dans89kx500:
I sent my cylinder to be resleeved today. The total cost was about $325.00. This includes new sleeved cylinder, piston set, gaskets and labor. Anyway, how much power do you lose with a steel sleeve? Is it a noticable amount?

stewart:
in my opionion  those cylinders are not made to be sleeved  it cause un nessary problems from longer warm up ,,less power breakage at port bridges ,,harder to keep head gaskets sealed  with disamler  metals ,,etc

BDI:
They say that the low friction coating is good for about Four horse power. I have heard of people having cast iron sleeves plated just for this reason alone.

Mick:
You say "resleeved"  :?  Why was it sleeved to begin with?  If it was because you destroyed your original cylinder you did the right thing.  A k5 cylinder costs about $500.  I'd sleeve anything to keep from spending that kind of dough.
I don't think you'd see another 4 hp with a half liter single...maybe out of a multi cylinder engine?  My CR jug is plated and I don't feel it makes anymore power because of it.

dans89kx500:
Yes the original cylinder was plated and damaged badly. I looked on ebay and checked company's to have it replated, but the cost would have put the old k5 out of business forever (to k5 heaven).
So, your saying about a 4hp loss?
