Snopczynski Posted August 20, 2007 Report Share Posted August 20, 2007 most of the time those cubs wont make any bottom end unless they are ported for it. So, chances are if its ported to be a top end motor, it isn't going to matter what pipes you bolt on it, it wont make a lot of bottom end power. We just went through the same thing with my friends dad's motor. For some reason he though bolting on a set of pt low-mid pipes was gonna fix it all. In the end, the motor had to be resleeved and reported for more botttom end power. Quote Link to comment Share on other sites More sharing options...

There are things you can do to them to make them perform like you want, but I'm a huge advocate of a 4mm stock cylinder setup with a dune port. It's just a more usable type of power for this type of riding, and will beat most bikes you come across drag racing as well. Quote Link to comment Share on other sites More sharing options...
1966nova Posted August 20, 2007 Author Report Share Posted August 20, 2007 (edited) yes the cylinders where very mimld port clean up by vito when my friend bought the comb.... he sold it to me at a very good price he is building a 10 mill.... i will try the advanced timing he said at 9-10+ you can only run it for short drags and let it cool down.... so i am going to try +7 we race usually on loose dirt about 500-800 ft... so hopefully this combo will come on strong on the topend... he said if i put the fmf fattys on it ill loose 10-12hp over the sheares...... the bike feels great but very doggy until have throttle..... but definatly its a to end monster hahahah ALSO will lighten flywheel help any thing?????

jbooker82 Posted August 20, 2007 Report Share Posted August 20, 2007 ALSO will lighten flywheel help any thing????? It will cost you bottom end grunt in exchange for top end snapieness Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted August 20, 2007 Report Share Posted August 20, 2007 yes the cylinders where very mimld port clean up by vito when my friend bought the comb Still really doesnt matter. The Cub is cast as a drag ported engine. Your not going to get low end power out of a drag ported engine. Quote Link to comment Share on other sites More sharing options...
RagunCajun Posted August 20, 2007 Report Share Posted August 20, 2007 (edited) low end from juggs made to drag race only? Should of just of gotten a shee with regular juggs and got a nice play port job. That's what i did. :shrug: Edited August 20, 2007 by RagunCajun Quote Link to comment Share on other sites More sharing options...
badassbanshee479 Posted August 20, 2007 Report Share Posted August 20, 2007 should have done a search, this topic has only been covered a 1000 times!! The cub cylinder, by design is a drag race cylinder right out of the box! this means that it will have very little bottom end, a decent mid range, and a top end that will rip your arms off! Yes you can choke it down and try and make it have more low end, but doesn't that defeat the purpose of having a drag race cylinder?? I would get rid of the cub and have a set of stock cylinders done up for the type of riding you will be doing. Cheaper in the long run, and will perform a hole lot better!!

Are cubs trail friendly part XXXXXVVVIIII No.. When I first built my 4 mil cub last year, I started with T5 pipes and stock carbs. That's about as much as you can choke it down without going to a single pipe/single carb setup. Put the timing at +12, get the compression to about 180PSI...and you absolutely must run full race fuel. That's as much low end and mid-range you're going to get out of that monster....period. And don't listen to the naysayers whine about that't too much timing....as long as your jetted correctly, it's not. Ask badassbanshee479 and bigboybanshee how much better their bikes ran once they ramped up the timing, they'll tell you..... Quote Link to comment Share on other sites More sharing options...
1966nova Posted August 20, 2007 Author Report Share Posted August 20, 2007 thanks for the replys ill play with the timing ,i just wanna make sure ill beat all the 4 strokes at the place we go ride i usually have but i could of used more topend so this cub will def have that........

Hope you got an override and lockup....cause it ain't gonna shift if not... If you were worried about beating four strokes, a strong dune port on stock cylinders is all you'd need....you went way overkill.... Quote Link to comment Share on other sites More sharing options...
