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 Value and Good Quality RV Queen-sized Comforter Set
Color: Beige Striped, Size: Full
We needed a smaller comforter for our RV bed to limit overhang and this one seemed like a good fit and we were right. The print is conservative and modern in appearance. The feel and thickness are perfect for our typical use in a warm weather state that we camp in year round. Last trip out it got pretty cold overnight and we let our dog sleep on our bed. When we returned home we washed it for the first time. I held my breath to see what condition it would be in afterwards and it came out in great condition. While we were using it, we noticed the weight, texture and comfort were all where we needed it to be and therefore we would recommend this if you needed an RV Queen sized comforter without breaking the bank.

Great comforter for the price
Color: Beige Striped, Size: California King
Nice comforter for the price. It looks great on the bed, feels soft, and keeps us warm without being heavy. If you’re looking for a weighted or very thick comforter, this isn’t it, but for a lightweight option it does the job well. We have a split California King Sleep Number (two Twin XL bases) and I ordered the California King size. It fits, but the side drop is pretty short. Next time I would go with an oversized King or oversized California King for better coverage. Bonus: no weird chemical smell when I opened the package, which is always a win.
