DESCRIPTION

Make the move to 750cc! This is the one, the classic, Morgo big bore kit!

Outstanding in Design and Performance the Morgo conversion is made to fit any 650c.c Triumph Unit or Pre Unit motor a 9 stud head has to be used on Pre-Unit engines  Can be fitted without any alterations to standard parts.

No reduction in bolt size or separate liners are employed in this conversion. The cylinder barrel is made from high quality cast iron, cast exclusively for us in the UK. The casting is one piece and only weighs a few ounces more than the standard barrel.

Supplied with cycle threads as standard, UNF threads to order only. Fin area increased by 20% to give greater cooling efficiency. We have introduced a fin tower at each side of the barrel to eliminate fin ringing at high speeds and to give more rigidity. Also the fins are much larger to give added cooling and blend in with the shape of the cylinder head.  Most important of all the strengthening pillars go up through the fins to give maximum strength to the base of the barrel.

Thread depth lowered by one full fin section to make available the possibility of removing top fin etc., for special purpose building without loss of thread depth, i.e., short stroke motors.

All pistons have cutaways for larger valves.

Standard compression ratio is 9.5 to 1 with a standard gasket. Alternative gaskets are available to give compression ratios of 9 to 1 and 11 to 1.

First produced in 1969 and with continuous research this product is used by thousands of discerning enthusiasts throughout the world both on the road and in competition.

Great sunblock, moisturizer, non-sticky and smells great!!
I’ve used a lot of sunscreen in my life being a fair skinned redhead and this product keeps me moisturized and prevented me from getting burned. We recently went to the French Polynesian islands and the sun hits hard down there and I never burned during our trip. I also absolutely loved how my skin felt moisturized and I never had dry skin from being in the pools and in the ocean. Plus, it smells amazing and you don’t feel sticky once it’s on.😊. Would highly recommend. Wish it was a little less in cost, but I love it.

Fantastic Sunscreen Lotion!
This sunscreen lotion is AMAZING! It smells fantastic (not at all like most sunscreen...cannot stand that nasty stink). And it is all natural so that is appealing as well. And yeah, it smells good and doesn't leave a gross/overly sticky type residue on your skin. It is also easy to wash off at the end of your day in the sun. And...most importantly, it works GREAT! Out in the sun and I didn't get burned at all. Highly recommend it (especially for anyone sensitive to regular sunscreen or if you can't tolerate the smell of regular sunscreen). This stuff is great!
