Brooklyn350 Posted February 20, 2021 Report Share Posted February 20, 2021 I’m having one built right now and wanted to hear from someone who has done this motor before. I feel like you don’t hear much about 472’s 4mil/72mm. I Know a 521 isnt too much more but I don’t want to run 39mm+ carbs and don’t know if it would do the best on 33’s. I’m going to get shit gas mileage anyway but hoping the 472 will be slightly better (I doubt it though). The 472 will be ported on 50/50 race gas and running snipers. Gary makes his pipes with adapters so technically you can make the pipes big bore or small bore, don’t know which will work better yet. Any feedback on the motor would be nice to hear.

Brooklyn350 Posted February 21, 2021 Author Report Share Posted February 21, 2021 Redline. Coming from a 421 wanted to do a 465 but he said wouldn’t be that much of difference and to try the 472. Def trust him, he’s the guru building them for a living. All said and done a 521 isn’t much more. Hope I don’t get a 521 bug down the line blowing money on all these motors. It’s all overkill for a trail bike but I want it. Gas mileage is going to a prob no matter what. Have a Clarke 5.5 and a six pack rack for long rides that holds a 2 gallon can.

locogato11283 Posted February 21, 2021 Report Share Posted February 21, 2021 It will be a good running motor. I have a 4mm Chubby from Redline. It's a drag motor but still very reliable and cheap to rebuild. I'd never build a 10mm for a trail motor. Quote Link to comment Share on other sites More sharing options...
Brooklyn350 Posted February 21, 2021 Author Report Share Posted February 21, 2021 Sounds good, I feel like not many people go that route when they build. Just about the same price as a 421 if your buying all new anyway. Looking forward to trying it out. Thanks for the feedback. Quote Link to comment Share on other sites More sharing options...
Boost231 Posted February 25, 2021 Report Share Posted February 25, 2021 Since cam @ redline is building it you will be super happy. My 472 from cam just shipped yesterday. I'll be running 33pwk on it to help some with fuel consumption. Made over 100hp on a trail / dune setup on snipers and 110. It could make more but wanted some low end power for the trails. I hope to have it up and running in the next few weeks. 1 Quote Link to comment Share on other sites More sharing options...
Brooklyn350 Posted February 25, 2021 Author Report Share Posted February 25, 2021 Nice I told Cam the same thing with low end. Im running almost the same setup, except I’ll be mixing 112&93 for fuel. Keep me posted on how it runs I’ve been waiting a while because cp has cylinders on back order. COVID has the world on back order... bullshit Quote Link to comment Share on other sites More sharing options...
Boost231 Posted February 25, 2021 Report Share Posted February 25, 2021 Can't believe it was just over a year to get mine built. I shipped it out Feb 6 of last year lol.. but good things come to those who wait. Quote Link to comment Share on other sites More sharing options...
Brooklyn350 Posted December 22, 2021 Author Report Share Posted December 22, 2021 Been a long wait thanks to all the bullshit going on in the world but almost done. Looking forward to getting the bike back together. Having Cam dyno it as well so hopefully I get the graph and can post it on here. I went with some bling to get nice and dirty in the trails.
