Just got done with a gal. threw the 3p rspec..(20%,extra shim).dynamite 053. 14t bell.(truggy).

0 poblems with tunning..its wicked fast..rarely used wot..now ill remove this shim..switch to 30%...and wait for my 0801..

I had no problems from break-in to now..the end of a gal.

hsn 1/4 in from flush
lsn 1 in from flush..
will idle threw a 150cc tank.
temps at 240 pretty much solid.

The Hsn is very touchy tho..go past 1/4 from flush..and the trouble starts..
Thast pretty much it...just like everyone has already stated ,the powers on the bottom needle for these go motors...I love mine..And I will buy another
