79cc Predator 4 stroke with 4G mount kit?

[KCvale]

I have a customer that wants more than a 49cc HS like an HF 79.
I was looking at kit parts for the platform, transfer case, sprockets, etc. and since I have built a few 4-strokers with 4G transfers I figured I see see what I could kit for without the motor.

This will make you laugh.

Complete 49cc HS 4-stroke 4G mid mount kit with engine $349.

Same kit without the HS 49cc engine $419.

$70 MORE to just buy the mount kit than the same kit WITH A 49cc HS ENGINE!

That is not why I am posting this topic, I just wanted to know what I may need to do to just put the HF 79 in and set the HS 49 aside for whatever as a 'super double bonus' for getting the rest of the kit for $70 less than buying it without the motor which covers 7/10 of the HF 79's $100 cost ;-}

I am waiting on the customer but I suggested he go with the HF Pred 212

And the Comet TAV2 GTC Torque Converter for that 212 Predator

That should be a creative build if bites but he'd be happy with a 79cc Pred but I like parts like this that are designed to go together than spending days on a customer build just trying to make parts fit together as the mounts, fuel and exhaust will fun enough on this one ;-}
