Anyone know where I can find some 321 parts ? (Piston/Sleeve/Rod), I have been looking all over the web and I know these parts are hard to find. But if any of you Board Bro's know a website or someone that has some parts for sale please let me know.

Thanks

Rod is no problem, The R7 will fit.

A 7 port PS set from any other 14mm crankshaft model can be used, currently you have the Kangaroo and the N21-7T models.

On the other hand, the total costs are very close to a new Kangaroo.....

Roelof, thanks for the 411 and I was afraid of that ( cost of a new kangaroo) but correct me if am wrong but I thought the 321 was a 8 port ?

Roelof

Sold as both I believe. The first 421 had a AAC set which was replaced by a ABC set and was leveled the same as the 321, the 8 port set was later replaced by a 7 port. Performance wise there is no real difference.

Do you have a 2 or 3mm thick upper edge on the sleeve? The 2mm is normal with current engines, the 3mm edge so far I have seen was on older REX models and current 9 port models.

A good 7 port P/S set with rod will cost you 250~300 dollar? With 100 bucks more you have a N21-7T or maybe even a Kangaroo. If you have some money left over just get a N21-3T P/S/R set for 100 bucks and buid up the old engine for fun.

I believe it has a 3mm edge, but I would have to check.

Roelof

Difficult... if it is 3mm you can fit a 35-plus, flash or 359 P/S set but then you are almost in the pricerange of a Kangaroo for sure. When placing a 2mm sleeve you have to get the right button head as well or add enough shims.

Maybe an idea to pinch the current P/S set? It is the most cheapest way.
(and get an Kangaroo )
