Well we are almost on the same page BUT... The XB heads are harder to come by and because they can be had, that made the TS heads drop in price. Ignition is no problem because if your running a hot EVO your going to upgrade anyway. You did hit on the very reason why buying a complete Buell engine is a very good idea!!! Buell has been building their engines since 1999. I'm pretty sure all Buells after 99 have the different bearings and lightened crank flywheels and you can hear the difference just by REVVVing the engine how fast it winds up! At the momment I'm waiting on an oilpump up grade that Buell installed on their 2007 engines. I have heard it has about 20% more scavaging and 10% more volume. I'll be installing a bronze drive gear also because of the horror storys of the gear eating itself:woohoo:that maybe true.. but if your gonna go thru that trouble why not do the xb1200 heads and have them played with and go with a cam of choice.. the sc 235 cams are a nice cam. i have a andrews n8 cam wich i think is the same lift as a n4 but more duration and i think over lap.. the n4 is comparable to the stock xb cam and the n8 makes a alot of power but its a drag cam and makes it all up high..
the thunderstorm heads are a good choice on a bidget build... make sure you have the heads send in and the squish set at 30% i think..(brain fart) what ever the stock squish is.. but have it milled so its even.. the stock castings are natourisly uneven. i would also send in and have the pistons matched to the heads at the same time.. while your at it send in your stock cylinders and have them bored over at the same time.....
and hugie you got an idea their.. by switching to the thunderstorm motor.. but outside of the cams pistons and heads their is no real difference(not includie the obvious difference of efi and ecu controlled timing.) they didnt start getting very difference untill the interduction of the xb platform wich also had a lighter crank too.... wich i am not sure if that can be put in.....
Those ""She" and "Her" would be all wrong....I be 52 years worth of Old Man still thinking he was young. Imagine a Tommy Lee Jones with short temper and hates knives but has more than the average 10 other people :woohoo:If your budget minded and want power then follow the list karsten posted.. "SHE" makes that with no mention of the heads being played with.. imagine "HER" setup with a full port&polish on the heads...... .
Oh yeah baby!!!Sporties are very capable of hurting a *** bike. I would like to see a sporty with a 3in stroke and a 4in bore! That would be very interesting........especially in a buell frame.
@gree:Oh yeah baby!!!
