FS lowell ported 84mm 66e twin topend
I am in the process of disasembling my Lowell topend on my xlt 800 BB and it is for sale. I know this is a desirable topend for the standup guys and will work well for a nice hp bump on any 66e platform like gp800r or xlt800.
I will check the hours but I believe there was 20 hours put on topend since new.
66e cyls were bored to 84mm, ported to lowells specs and reniked, with prox pistons. 2 pv were cut to match
head was cut to match the bore and compression just measured the other day at 162lbs on both cylinders.
a head gasket was cut to match and the current head gasket has 1 hour run time.
I will send pics to those that are interested, I am leaving town till August 2nd and won't have pics till then.
I will post a price soon but I can't find my original receipt.
This topend makes great power and my xlt800 would run with a stock xlt1200
my guess is the hp went from 120 stock to 140+
I have 2 props for the the topend also. More info soon on price etc.
Pm me with any questions

here is a response from Lowell Horning, the portsmith who did the work on motor.
"The exh. is opened for 1300. All transfer ports are set at same height. Boost port is raised. Transfer base is raised. All air transfer surfaces are smoothed / sanded. All ports were chamfered Before plating was done."

topend is relisted, buyer has not come up with funds and is now non responsive.
Make an offer I need to get the topend SOLD. I will throw in the req'd carb parts, jetting and N/S combo, to set it straight.
Also, looking to trade Island racing modded 66e carbs for a stock carb rack.
My carbs have choke plates and accel pump removed, fitting in place for primer and will supply primer pump.

doug I have stock carbs with the same mods, if your looking for a set to go back to stock my will work just add the primer to the ski. Not hard to do and probably easier to sell, better for the ski!
