NickisGod Posted May 3, 2010 Report Share Posted May 3, 2010 I have the 485 pv cheetah and can't get the sob to fire right. I'm starting to wonder if the pv has something to do with my issue. Idk they look cool and if mine did wat they say, sound cool too. Quote Link to comment Share on other sites More sharing options...
SLORYDER Posted May 3, 2010 Report Share Posted May 3, 2010 anyone ever run a pv 421. i have a 421 now but im interested in a pv one anyone have any experciance with one. Well mine was a 521 (10 mill) and I really liked it. The main difference is that pv bikes are so much more effortless to ride. Mine was geared for 100mph and I could launch it in 3rd. Going up big dunes was child's play due to the fact that you could go without having to worry about what gear you're in or slipping the clutch and having these sudden jolts of power. That said the non pv version is just as fast and probly more fun in the short term because of the explosive powerband. PV motor pulls hard from almost any rpm with the top end of a cub. I would not hesitate to build another one if my funds were taller. Oh and mine had trinity pipes and 35mm carbs. Would like to have done 39's and cpi pipes Quote Link to comment Share on other sites More sharing options...

LIM_Whiteboy4life Posted May 3, 2010 Report Share Posted May 3, 2010 i just built my 421 cheetah 35pwks, SB cpi inframes , and my buddy has a 535 10mil cheetah, 39pwk's, BB cpi inframes. Both machines are animals but to build a "cheap" pv'ed motor get a 421, use a long rod 4mil crank and blaster 573 series pistons. Make a really well rounded machine, just keep those powervalves clean and it will keep you happy. Quote Link to comment Share on other sites More sharing options...
camatv Posted May 13, 2010 Report Share Posted May 13, 2010 they are sweet. if you can afford the top end.. not sure why they are soooo much more than a cub.. part to part there is about 700-900+ bucks there for profit i 'd imagine.. i have a 485 and a 535 pv motor love them..

I think it's the powervalves that are like 250 apiece. Plus the "special head" Hech I think trinity charges 330 for the pistons. Thake all that away and you are near cub territory Quote Link to comment Share on other sites More sharing options...
camatv Posted May 17, 2010 Report Share Posted May 17, 2010 (edited) the billet valves shouldnt cost 500 bucks.. the head is CAST and shouldnt cost that much either... its a price gouge compared to a cub. a ct 350cc honda cylinder with pv and head is around 1000 bucks or less..

chugger Posted May 19, 2010 Report Share Posted May 19, 2010 I have a pv'ed 421 cheetah, sb rdz/shearer inframes, 39 pwks on gas and love it but you do have to keep the pv's clean or it wont act right. But the power is always there and builds so quickly compared to a cub. Quote Link to comment Share on other sites More sharing options...
