cciao Posted June 26, 2013 Report Share Posted June 26, 2013 Doing a rebuild a blown banshee and was thinking rather than doing a 4 mil Nd buying everything new , bored, ported. Why not just buy the 421 cheetah cub kit. I think I would be better off. My question is a 4 mil kit for me? What can I expect? I want to set up for Xc/woods/ drag for fun and sometimes mx. I don't race but like to go fast. Only owned one other shee that was mainly bolt on performance -pipes, reeds, milled head, bored, timing plate. I thought it was fun and fast. Question is , I never rode a 4mil what's it like? Is it too much for my riding style? Thanks Quote Link to comment Share on other sites More sharing options...
Colby Posted June 26, 2013 Report Share Posted June 26, 2013 you would be more pleased with a stock cylinder 4 mil w/ a good dune/play port .. Quote Link to comment Share on other sites More sharing options...
WINDYCITYJOHN400 Posted June 26, 2013 Report Share Posted June 26, 2013 In general....to much of a "top end power" kind of motor. The cubs only really shine in the higher RPM's. Other than the occasional drag race...the cub will be a bad fit for your kind or riding. (Some will claim to be able to ride almost anything in the trails) but I feel that a cub is overkill for the kind of riding your into. If you have never ridden a well built stock style cylinder bike...then your in for a treat. I'd contact a site sponsor about building a nice ported 4 mill. Don't go talking about dragracing. Just get a good play port. HJR FAST REDLINE They can all hook you up. Don't chase big HP numbers. 60-65HP is a ton of fun and won't be an overpowered handfull that needs a massive swingarm. 1 Quote Link to comment Share on other sites More sharing options...
cciao Posted June 26, 2013 Author Report Share Posted June 26, 2013 Ok so stock cylinders, 4mill crank with dune/port would fit me better.? Now what's the difference woods port vs. dune? Quote Link to comment Share on other sites More sharing options...
cciao Posted June 26, 2013 Author Report Share Posted June 26, 2013 And with the stock cylinders 4mill port and bolt ons would it be smart to run a set of pipes like CPIs for my style of riding or stick with the t5s or pro circuits. Quote Link to comment Share on other sites More sharing options...
Colby Posted June 26, 2013 Report Share Posted June 26, 2013 T-5's will do fine .. CPI will give you a bit move over-rev Quote Link to comment Share on other sites More sharing options...
cciao Posted June 26, 2013 Author Report Share Posted June 26, 2013 Thanks for the input, just learning all the variation of the 4 mill . U have a pro design cool head what size domes should I be looking at with this set up and can I still run pump gas ? Quote Link to comment Share on other sites More sharing options...
Surfrjag Posted June 26, 2013 Report Share Posted June 26, 2013 Did you call a builder? Quote Link to comment Share on other sites More sharing options...
cciao Posted June 26, 2013 Author Report Share Posted June 26, 2013 No not yet . I'm lookin at Hjr. I like the kits they have. I'm in no hurry just gathering as much info before I make the move. Quote Link to comment Share on other sites More sharing options...
toytech Posted June 26, 2013 Report Share Posted June 26, 2013 Jeff at fast did a 4mil dune port for me. I run the R2 pipes 35mm carbs the thing is awsome trails drags and dunes. Quote Link to comment Share on other sites More sharing options...
Colby Posted June 27, 2013 Report Share Posted June 27, 2013 No not yet . I'm lookin at Hjr. I like the kits they have. good choice.. his 4 mil dune ports ROCK ! Quote Link to comment Share on other sites More sharing options...
Zillaguy Posted June 28, 2013 Report Share Posted June 28, 2013 I run a 4mil stock cylinder, 4 mil aggressive dune port, 65.00mm bore, Coolhead w/ 19cc stroker cut domes (pump gas), FMF Gold Series, timing plate +7, VF3, billet intakes stock carbs.. It runs pretty sweet, massive improvement over a stock stroke motor... alot more torque for sure! I do the same kind of riding you do, and was thinking 421 cub or serval until I did the research on the 4mil stock cylinder set-up.. Glad I went this way it's a blast to ride in the woods.. Not overpowered, just.. Perfect! LOL 1 Quote Link to comment Share on other sites More sharing options...
Frito Posted June 29, 2013 Report Share Posted June 29, 2013 so i have a few questions on this topic, first what is the life on a 4 mil w/t the stock cylinder( not racing just riding sand dune's) and also any recommendations for anyone in Oregon that can build that set up?

trickedcarbine Posted June 29, 2013 Report Share Posted June 29, 2013 Oregon has some really sweet dunes and with a little research on here you can get a good idea of what type of motors are really working out there in all the idiot holes. Lew at twister is in Boring Oregon out there, but I bet you would also be extremely happy with Cam at redline as well. Quote Link to comment Share on other sites More sharing options...

There are several top quality builders in Oregon. Redline and White Knuckle are both site sponsors and do great work. Twister is also here in OR.
