SIP GS150 to PX engine adaptor

Hi Guys/Girls.

I am intending fitting a Rally 200 engine into a VS5.

Sip sell 2 adpators:

http://www.sip-scootershop.com/en/products/adaptor+serie+pro+engine+swing_63009000

SIP say with the first one 63003000 the wheel rim will need to be reversed in order to get the correct wheel runnig centreline. I dont want to to do this as extra load will be placed on the rear layshaft bearings.

The second one 63009000 appers to mount the engine further away from the engine side that the 6300300. This i presume would negate the rim reversal issue.

Does anyone have experience of either of these adaptors? Any advice appreciated.

Also has anyone fitted a Rally/P2 engine into a GS150 with or witohut these kits?

Cheers,

Rally Jim
