Honda CBR throttle bodies

[markh]

Hi Any one know if you can get bigger injectors for Honda CBR 600 Tbs, have looked on various Bike forums and can't see/find any ref

I'didnt come across any. I looked at the altiss manifolds for the cbr600 but the cbr t/bs are good for about 50 bhp each. as we can alraedy see almost that much They suggested gsxr 750/1000 k1 or k2 t/bs which are good for upto 75bhp each and they will do a manifold to suit.


that was the route i was going to take untill ACT made us an offer we couldnt refuse on je manifolds and Jenveys

Graham, thanks for the info, but I think 50bhp per tb is way off, I',m getting nowhere near 400bhp and the injectors are maxed out, so I think I'll look into the fireblade units, it's a real shame because it drives so well, so smooth and resonsive, just hope the larger ones don't bugger that up.

cheers Mark

good job we didnt go the cbr route then.... we can get 370 on standard plenum, with a blended base....

i cant wait for the jenvey's to turn up yum yum....

370 bhp was that run on magic dust and built by one of Santa's little helpers, or......... just a very dodgy dyno

Markh,dont mean to be ignorant,are you on the bike throttle bodies now,what ECU are you using,only interested because i would like to go down this road,thanks.my biggest challenge is making the manifolds up.

[markh]

Yes you are right I'm using Honda CBR Tb's the inlet manifolds were made by these people www.altiss.com/ and a nice job too, the ecu is an Autronic SM-4,the engine is now balanced, lightened with some Rob from V8D big valve heads and one of his 'stealth cam’s, roller rockers, baffled sump etc. The finished results are great; it feels really strong and pulls very well, with no sign of any temperament, ticks over at 750rpm.

You can also try BOGG Bros limited. They are around filey / bridlington way in eastern yorkshire. They are known to make custom manifolds suitable for bike carbs.
