SuperMex Posted September 2, 2011 Report Share Posted September 2, 2011 Ok, I am putting together a 421 Serval this month and will be dynoing it with Shearer small bores vs R-2s. The Bike will be a 421 Serval bought from M&M atv with Hinson Spring Loaded Basket w/Straight cuts, F.A.S.T. Clutch, Cut trans but not full override, Shift Star Mod, Billet Impeller, Stock Gearing 14-41, 34mm PJ's w/6" pods, V-Force reeds, Boss Billet Intake w/ built in crossover, Fluidyne over sized Radiator, NOSS Head w/ 24cc Domes. That's all I can think of for now so I will dyno it and run a comparison on these two sets of pipes. I'll keep you guys posted on the build and eventually the Dyno #'s.

SuperMex Posted September 2, 2011 Author Report Share Posted September 2, 2011 I currently have a dune ported stock cylinder and have ran T5s and the R-2s on them and I can tell you the R-2s come on just as soon and pull hard and rev to the moon. I think they are a much better all around pipe than the T5s like a CPI but rev out longer than the CPIs. Now to see how they do on a Serval, should be fun.

CFH87 Posted September 2, 2011 Report Share Posted September 2, 2011 R-2's have a bad ass sound to them... Wonder how the shearer pipes will do. Quote Link to comment Share on other sites More sharing options...
SuperMex Posted September 2, 2011 Author Report Share Posted September 2, 2011 Yeah I love my R-2s they sound and look sick Quote Link to comment Share on other sites More sharing options...
Strm Trpr Posted September 2, 2011 Report Share Posted September 2, 2011 NICE, I too will be following this thread. On another note, how the heck do you change plugs with those R2's? Quote Link to comment Share on other sites More sharing options...
SuperMex Posted September 2, 2011 Author Report Share Posted September 2, 2011 NICE, I too will be following this thread. On another note, how the heck do you change plugs with those R2's? If the pipes are hot I wear gloves and I am very careful these babies get HOTTTTT, but if the pipes are cool its just as easy as with T5s just a different angle.

figjam Posted September 2, 2011 Report Share Posted September 2, 2011 Why new domes?? You got those with the serval kit from Andy right? Quote Link to comment Share on other sites More sharing options...
Strm Trpr Posted September 2, 2011 Report Share Posted September 2, 2011 Why new domes?? You got those with the serval kit from Andy right? If he bought the domes for the Serval he's good to go. Quote Link to comment Share on other sites More sharing options...
SuperMex Posted September 2, 2011 Author Report Share Posted September 2, 2011 Yeah, kit from Andy has domes Quote Link to comment Share on other sites More sharing options...
Strm Trpr Posted September 2, 2011 Report Share Posted September 2, 2011 Cool. For one reason or another I thought you were running the Noss Head and Domes on your Dune Port Stk Cyl... My Bad I can't wait for results. Did Andy do a clean-up port on the Serval? Quote Link to comment Share on other sites More sharing options...
figjam Posted September 2, 2011 Report Share Posted September 2, 2011 I also imported this kit from Andy a week ago. Should be arriving next week! Can't wait, still need to buy all the clutch mods and stuff like that. Also ordered 24cc custom domes, Hopefully it's fine, I'm at sealevel. Are you running extended swingarm? What size dirt tires will you be using?? Quote Link to comment Share on other sites More sharing options...
SuperMex Posted September 3, 2011 Author Report Share Posted September 3, 2011 yeah, I am running a +6 swing arm and 24cc domes as well I am at sea level also. I just use the stock tires on it since I trail ride it very rarely thats what my CRF450R is for. For sand I run 20-10-10, 9 paddle Skat-Trak haulers.

Fastassbanshee96 Posted September 3, 2011 Report Share Posted September 3, 2011 I've got the same setup except I have 22cc domes. I'm still doing the break in and running R2 pipes and so far I love it. I plan on getting all broke in this weekend. Quote Link to comment Share on other sites More sharing options...
