CBR RR throttle bodies

[peterbaron]

Here is something I think about when I think about performace upgrades. Some of the greatest engineers or mechanics or tuners are Japanese. The CB is hugely popular in Japan. The aftermarket for the CB is huge in Japan. If much could be easily gained by massaging this motor as some would have you believe, one would think Samurider would show big bore kits, cams, larger valves etc on his website available for purchase. It was certainly like that with other Japanese bikes the entire time I was in the motorcycle industry from 1972 to 1989. Performance enhancing mods are readily available for other Japanese bikes..ZRX's, Hyabusas, GSXR's and many other bikes that don't really need it, but not being available for one that quite a few people feel could use a boost, and would gladly pay for makes little sense to me. You can buy fairings, and exhaust systems, and swingarms and wheels, and sprockets and body parts galore, any little trinket to make it prettier, or tricker than the next guys, but not one motor part offering to make it faster. Why do you think that is?

Like I said, just something I sometimes think about.

+1, Ferret, thank you for your wise read

1* If I had, lets say a 120 HP CB air cooled engine , I am more than certain, it would not be enough for some members, these would like to have a 150 HP one , and if they got it, these would say...now entire frame is too weak and other parts cannot withstand this load or mechanical stress, causing the CB to have a short life..and burns too much gas now...and would be unhappy again....and even if you had air cooled one, HEAT would be your worse enemy...
2* Some members have a big plan with engine modification backed by NO engineering +++ knowledge..so for these my advice is: put the money where your mouth is..
3* In my entire automotive life, I met only two people who have adequate knowledge about cams ++, one was my friend who used to race cars and had automotive racing shop closed to public and the other one is PowerDubs...and even he tells members what to expect + think before you start !!!

I used to port and modify small 2-stroke, carbureted engines (up to 175 cc) and believe me, 4 stroke MPI, air cooled is totally different = much more difficult animal.

Good luck to all amateur modifiers ..., stop playing engineers without eng. degree ....
