Carpenter 240 Kit questions

As jvheli said the transmission is nothing to do with the Carpenter package.

That said, it is not uncommon for a mid teens year Rocket trans to suffer fatality, regardless of engine power although I would suspect an increased power bike will put extra stress on a trans that was already prone for destined to dislodge a poorly installed factory circlip.
The 4th output gear is a bit anaemic hence Robinson industries have a billet version available.
They will also enhance your transmission so it is assembled correctly and won't develop the not uncommon issues as above.
You could get the transmission work done too, subcobtracted by Carpenter, if you felt uneasy about your trans.
I've about 15k miles done on the Carpenter engine and no trans issues. 2010 Roadster.

For some light reading and understanding the 240 kit a bit more (few tidbits that are good to know going in), you might want to read;

How To: Fit Carpenter Racing 210/240/265hp Kit (Inc. Dialling In Cams)

Following a few requests from fellow captains recently – not so much of an unofficial “how to”, as it is just a documentation of “how I did it” (took me a solid week the first time) This is in NO WAY a substitute for the expert guidance of Bob Carpenter & his boys. You need to be at least very...

But ultimately this is a demonstration of Carpenter 240whp Rocket performance;

 
I second the Metz change. I won’t go into more than the tire just isn’t sticky enough for that much power.
I can’t speak for Carpenters tuning services since I’ve never used them. However, @Steel used a tuner he endorsed close to Carpenters shop. Matter of fact, Bob also uses them.
 

as some r3 riders have done is to replace #4 gear which is the weak link in the gear box robinson industries in new york have a billet #4 that they install when backcutting all the gears you might want to talk to them
 
Tommy @Steel uses him, he nails the tune, he does the triumph rocket rocket
 

Well that's just the way of all things mechanical is it not? This monster is an investment in my eyes. I plan of having her for a long while. If the transmission craps the bed, then it was meant to head off somewhere like Robinsons or back to Bob Ha!!! I'll trust whatever Bob tells me. When he wrings the bikes neck during the dyno part of the 240 kit and says he suggests I get the tranny done, so be it. All of you have been awesome thanks so much!!! I feel much better hearing from all of you. I look forward to swapping the rear tire after smoking it when the bike gets back from Bob.
 
BTW, R3R Turbo, the few videos online that show what carpenter rockets can do bring tears to my eyes
 
Love this video is it you R-111-R Turbo

To me, the trans and the 240 kit have nothing to do with each other. And it’s no guarantee the trans won’t fail.

Mine still going fine with stock clutch and trans.
