Dax Balanced lower...?

Help me out here fellas....

Looked around and didnt find any comments on whether the "Balanced Lower Duane at Thats Dax is selling has been found to be a better lower than stock.

If you have one of these engines and you have seen a good result and less vibes than what most stock engine produce let me know, Im possibly interested in trying one of those lowers for my next build.

Peace, Map

yes price does seem right if it is actually an improvement.

I just went to Duanes site and ordered the balanced lower end, I have a new jug and some high quality wrist pin bearings, I have one of those bright green Walmart fixie bikes I bought on clearance for $50 and just stuck back in the shop about a year and a half ago so that will make a good bike to try this engine on, I will loose the Red & Yellow colored clown looking tires that are on the bike though...LOL!

I'll post a pic of the bike asap on this thread, frame seems ok on it and welds aren't beautiful but not bad looking so I'm hoping for a good bike when I'm done.

Peace, Map

Thats great WildBill, may take me a while to get mine together but if you beat me to the finished build I will be looking forward to hearing about your results.

I paid $80 for a PK-80 lower a couple years ago that is still sitting in pieces in a box, I tore it down for several mods and just havent taken time to put it back together, if the Dax engine really does have a better balance and better internal components ( Bearings ) like I have read about, it is for sure a good deal and I'm excited to find out.

Hello there Aleman,

Thanks for the welcome back, I know I been out of pocket for a good while now, just crazy things in life, getting things sorted out again so I'm looking forward to seeing what everyone is doing now days and what new gadgets we have access to, I been seeing that a lot of people are buying those Jaguar CDI set ups it seems, I've wondered about them myself, but I get 38-40MPH out of my bikes with the stock CDI's so I don't know if there would be anything for me to gain with them, I guess this is the gadget to have now....LOL!

Personally I'm looking forward to seeing how that balanced lower from Duane works out, if it is just 25-30% smoother at cruising speeds that will be great, I've been able to manage the rest of the issues with the 2 smokers pretty good but the vibes have been the biggest killer of these little engine IMHO, even good quality bearing will finally give it up under serious vibes after a while.

If I remember right you pretty much said to heck with the 2 smokes and are solid with the 4's now, how are you builds holding up and have you figured out any neat tricks on them?

Thanks again Aleman, good to hear from ya.

Peace, Map

Yes. These new Block Lowers have the single piece steel 360 full circle GP crank hand drilled and balanced. Also.. These blocks use the Grade 8.8 Case and mounting studs to boot. Rod used is 3 center holes also hand drilled for superior oiling. Rod length is 110mm. This also allows for a lighter rod for faster revs. I am in the process of applying for copyrights to the crank design.. Current testing shows this is the best crank ever for these little engines. Also.. I am waiting for feedback from other users and racers that are now procuring these lower ends. Normally, the the crank used is Iron 2 piece and is screwed together. This new Crank is Steel and full circle. It is more precise and allows for tighter tolerances thus occupying more area in the block creating higher velocities resulting in hp gain. Even more hp is gained because this steel crank is lighter allowing it to rev up faster.. We are awaiting more real time feed back on this lower block. As I said before, pre sale testing was impressive. We test everything first.. Enjoy the ride..

The BGF motors are a crap shoot just like some of the other IMHO but...... I have one of the older style motors I got from him back in 2009 that is still running strong with 1600+ miles on it so far, completely stock with only a home built exhaust and the NT carb rejetted, it will hit a GPS'd 41 MPH with the 32T sprocket I have on the 24" rear wheel, it feels and sounds as if it's about to blow.....! at that speed but it will get there on a flat without any head wind if Im tucked in tight on the bike....LOL!

This is one of the old engines with the 6mm head studs with a straight plug head.
I'm sure I just got lucky on this one and if so, I'm glad because it has been a very sweet little engine, I do wish it was a bit smoother at 30mph, its not really bad vibes but will buzz the hands a bit after 8-10 miles at that speed.

I've got what I think is a Flying Horse engine on another bike an it is a pretty smooth runner, good power, bought it on an old bike that someone tried to get going but never did, paid $75 for the the Mood Dog cruiser and the Engine combined, good riding bike.

I'm like you biknut in that the Dax motor does sound impressive and I really hope it is a couple notches up from what I have now, even if its just a smoother engine and I still get about the same speeds out of it I'll be happy, I'm not looking to go 50mph on my bikes, I have a Harley and an old Yamaha Maxim for that............lol! I just want to be able to enjoy the bike rides more by them being more comfortable and as reliable as possible, I have a few people wanting me to build them bikes but I want to find an engine that is smoother running and will hold up a bit better than the BGF & others average engines.

I gotta say, that really does sound impressive Duane. The best motors I've tried had the truest cranks. Anyone would be stupid to buy a BGF motor instead of one of yours.
