These were sent to me. I will post for your review and to throw stones. The porting shop is labled by the owner who paid to have this work done. I am copying and pasting his comments of what they found when they opened the motor inthe email I received.



PIC #1

0290 - Note the JBWeld repair after coolant came out the exhaust when motor

first installed.

0295 - No bevel on any exhaust ports of the two motors

0296/0297 - looks like the rotors were never cleaned according to Steve.

This motor ran in the garage for about 5 hours total.

0303 - motor no. 3 had lot of blow-by and low oil pressure. Here we see the

worst blow-by where the side seal was stuck. The other side of the rotor

has small amounts of blow-by at the corners.

0305 - No bevel on exhaust port and odd shaped port. If you notice many of

the lines on the ports aren't straight or symmetrical.

0306 - I paid for stage 3/large port. Notice that one motor has ports so

big the plates are junk and the last motor has mild port. Note how the huge

port motor intake opens early. More like n/a porting. The motors did have

the 3mm hurleys that I paid for but he used two different style corner

seals.

0309 - Nice gouge in the bearing.

l8t apex 01-14-2004 07:17 PM

0310 - Oil jets for bearings were enlarged but notice how the edges weren't

cleaned up.

0315 - Notice the difference in port closing. One is higher and the shapes

are different.
