we ran that head set up with both touring cam and race cam and found it will still have a blurpy bottom end power band even with a 24 or 26 mm carb remember the carb size should match the intake valve size and the Ultra head has a 26 mm OD port and a 25mm valve on the intake side and 21 on the exhuast .



We fixed this problem by running a 20mm carb with jets drilled to twice there size for methanal and it ran like a beast but still burped a little but spanked everything in site .



PS. Classic has the new 117cc SE Kitaco set up now for $1395.00 Lyle had a couple of these air freighted to us from Japan before they were available to the public and man I 'am talking super rocket horse power and performance that beats the 124cc 4 valve head Takagawa set up for thousands less check it out you won't be sorry you did

yeh baby the 117 is fast but here in cali our tracks are wide open and thats what you need .



Hey remember that either the touring cam or the race cam is going to give you bottom end power problems it is the nature of the beast . there is so much cam over lap that that sucker is blowing gas back out the carb . try a lower octane gas it burns quiker than high octane this might help if not run methanal with a manual clutch set up it rides like a two stroke but man the power is incredible .



Hey That Bean is a super cool guy and quiker than snot .



PS. I have a ultrahead set up for sale. we converted it to a 118cc on methanal PM if you are intrested
