......................Regarding the 36 hp figure, we'll wait and see.Being that I have seen and flow-bench tested the UCE head, and know what is in there, I can say that it will need more than a 3mm overbore and a "throttle body and exhaust", to get there..........
The cam profiles are key to ANY real performance enhancement. Anyone who thinks a larger piston & some port polishing is enough is using a "big hammer" kinda approach.I'd like to see the mod be a 535 piston & new cams (with requisite injector & exhaust work).
::opinion mode ON ::recalling my days building JeeP engines ....seems to me, high-lift, short duration cams with a relatively small angle between the peaks is a formula for a high-torque, low RPM engine. The higer performing engines had a larger angle between lobes, and, a longer duration ..... scavenging and all that ....::opinion mode off::I respect the time it takes to design a street-able modification kit that will be both economical and worthy of the investment to mass-produce. Ace has taken on a monumental task here !!!!
Ace, was the development of the original Fireball more or less straightforward than the UCE?And very glad to hear that progress is being made.Scott
Maybe I'm all wet but it seems to me that perhaps a slight increase in the valve lift coupled with changing both cams to increase the dwell and overlap condition could increase the flow at higher speeds.If this were coupled with some exhaust and inlet tuning to take advantage of the overlap a improvement in the upper RPM range might be possible.Of course this would require a revision of the ECU to accommodate the higher RPM and the lower would probably need modifying to keep it all together.Just thinking...
It's questionable if the owners really want to rev higher, or if a good solid power curve up to 5500 rpm would suit them for most purposes.
Indeed. Higher revs is more vibration means more wear & tear, loss of bolts and stuff csq. more prevention & maintenance and less riding.Every time I tested for the maxspeed (132kpu and 122kpu average on stretches of under 20kms) mother physics presented me the bill: taxplate holder falling off because of all three welds failing being the more amusing adventurette as it happened on a busy crossing.In the longer run I associate high vibrations with decreased life expectancy.Are those also issues that have your interest or are they factored in in an inherent trade off (more speed vs less life)?Let there be no misunderstanding: I follow with interest what you're doing and appreciate your method and efforts. It's not because it ain't my cup o'tea I can't be supportive. Although I would appreciate it if there was someone out there, just like you, working with the same gusto on the adventure qualities of the bullet.
Hello all! Been away a long time but news of this bike brought me back. Although they look good, neither myself nor my back have any interest in riding cafe-style. I am, however, interested in the up-rated engine and the newer frame and suspension. I note that a better seat is available but would want standard-height bars. Anybody know if those will be available?
Is it the same crank/con rod in the 535?

..........you can use your standard UCE and get the cams, piston, barrel and head for the Cafe Racer........
The bars are pretty easy to change to anything you want, although it's possible you made need to change cables to the standard UCE model. The seat may be a bit more of a problem, but you can always refoam and recover the stock pan.Or you can use your standard UCE and get the cams, piston, barrel and head for the Cafe Racer.Bare
is the gear changer still on the left hand side
@ROYALISTA....Of ALL the manufacturers I think RE Is right on with getting into the cafe racer THANG. They should be at the fore front. There are sooo many bandwagoners i.e. Guzzi, triumph, that dont have the soul their old bikes used to have. Riding a triumph now is kind of like riding a honda. AND they are assembled in Thailand(retro models) and still cost a fortune.Only think I see RE blowing it on is the price. Everythings just gettin too high.Thats my 2 cents.
