I think if the triples were as bad ass as everyone says the stocks sleds would still be running them. Or are they too fast?
Triples are not as prevelant as they used to because the marketing/warranty departments have been pushing twins. Never mind that an XCR 800 makes more HP/TQ than a 800 twin at every RPM point that matters. I think triples are not as around currently as the factories like the simplicity of twins. It allowed them to go backwards with HP, reduce liability/warranty costs due to people who hopped up a seld and then installed factory pipes when they burned it down on the triples.
Its a cyclical thing in sled engines, triples in the 80's and early 90's twins from the late 90's to current day. I still hear rumors of triple engines running around Roseau. They will be back as you can only reliably get so much power out of a 800 twin before you need the increased piston area and ports to make the power a triple is easily capable of. I would be at the Polaris dealership tommorow if they had a 800-1000cc CFI triple in a production sled.
As far as big bore twins, Carl's Cycles 910 is sure to please, although it does require a race gas mix. Engine Techs 900 kit can be run on pump gas with a single pipe and sure is a runner. Either way you will be happy with those two companies, both have invested a lot of time and effort into their big bore kits to ensure you get a reliable/fun package. Stay away from PSI/Hotseat.
Yes, the triples are fast, real, real fast.
