Motor question/stock exhaust question.

[Captain PegLeg]

I am building a motor for a wr3 so we can have friends come with, and to pull tubes, coolers, people, accross the lake to save alot of driving. Pretty much a commuter ski. My question is, can i put a set of 760 jugs on it, and still run the stock exhaust from the 61x setup?! Need to know pretty quick so i can get my priorities in straight...

The 61x is weak in a big sitdown, (not that the wr3 is any better, but its all i could afford, LOL!) so i was gonna bore a 760 cylinder and put it on the 61x cases for a little more "tubin" power...... but just need to know if the stock exhaust will work! Thanks guys! :swordfight:

The holes in the cylinder for the exhaust manifold are different. You could use bigger bolts or put timeserts in the holes to make them the right size.
Also, look at the head. 62T cylinders mount towards the rear. don't remember if the stock exhaust bolts to the rear or front of the head, but it needs to match -obviously.

hum... maybe a aftermarket head or something? But it is possible?
