tuning options for PK50XLS

[gus]

gday,
im over visiting my family in switzerland, and have just picked up a 1990 PK50XLS plurimatic for very cheap..

i wanna give it a bit more power but im new to the whole smallframe tuning malarkey, does anyone have any suggestions?

im living in a flat so id prefer it if i didnt have to change the crank or gearing setup or anything that requires splitting the cases.. at least not at the moment..

is there any problems using a kit on a bike with an auto transmission?

if possible id also like to keep it under about 150-200 pounds worth of bits..

any suggestions would be appreciated..

cheers
gus

Welcome to the forum.

To be honest I know next to bugger all about the auto's other than nothing is compatable with the manual engines.

Your very limited for parts but you can get these.Checkout the links to see what else is available for them.

I would at least recommend you buy the cylinder head and a new drive belt and gasket set.

cheers for that mate

i found that kit on ebay today as well.. seems thats my only option..

would i need to change my carb or pipe or anything?

lucky it was cheap!

looking at sip, the only exhaust seems to be the sito plus which will be a bit better than the standard though if you only change the outlet pipe which the exhaust fixes onto this would help.

know nothing about the carb on an auto, but you should at least upjet it.
