fbt551 Posted July 30, 2014 Report Share Posted July 30, 2014 What power diffrence would I see going from my t5s on my ported 350 going to rocket big bore pipes? Running 198* exhaust and I believe 130* on the transfers on a stock bore stock stroke bike on alky Quote Link to comment Share on other sites More sharing options...
Nightmare Posted July 30, 2014 Report Share Posted July 30, 2014 I put rockets on my 350 just to ride around while my oof were being repaired and it falls hard, even messed with the jetting. Big bore pipes are for big motors (10 mill +). I'll be selling my rockets in the next 2 weeks. Quote Link to comment Share on other sites More sharing options...

locogato11283 Posted July 31, 2014 Report Share Posted July 31, 2014 Rockets are small bores. Quote Link to comment Share on other sites More sharing options...
Zillaguy Posted August 1, 2014 Report Share Posted August 1, 2014 (edited) Rockets are small bore pipes... They work best on ported motors with bores 68mm or smaller... From what Tom said they like higher port times too. Edited August 1, 2014 by Zillaguy Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted August 1, 2014 Report Share Posted August 1, 2014 Rockets are small bore pipes... They work best on ported motors with bores 68mm or smaller... From what Tom said they like higher port times too.They most definitely do like the exhaust to have a ridiculous duration. Short of upper 190's and you will notice a definite flat top end on them. Been thinking of messing with the stinger diameter to see if that can be fudged around or if it will also allow for use on motors with a bit more displacement.

Zillaguy Posted August 2, 2014 Report Share Posted August 2, 2014 I'm running 196ex 128tr with Rocket R1's. The power comes on just into the midrange and pulls all the way to the top... Best mod i've done so far, except for the porting and 4 mill. Quote Link to comment Share on other sites More sharing options...
