125-200cc CR/WR/WB 177

I ordered the bearings I needed by the nr on the bearings (no Kit)

I did get the steel coated ones and I am be happy with it

I do want to make a test set up in a 2 similar pumps and one i want to change the bearings of the electro driver to sea how much it odes make a difference

Holy smokes walt... You are a tinkerer... Thats for sure!!! Good job buddy. How are you not making millions by now??

I guess I would have to actually charge enough to make money and up the volume by 1000 fold. Wait then it would become a full time job with a staff......no thanks.

JOB ??? IS THE GOLF COURSE NOT UNDER 4 FEET OF SNOW

Yes the course is under snow but in two weeks the guys come back to work and we are on for 8 months. For me that means pretty much 7 days a week. I keep my evenings free for doing this as it tends to relax me and keep my mind off the BS.

ok hears a plan lets all go fubar Walts golf course too a BS free state and keep it that way then verybody buy a wally bean built motor so he dont starve Walt you mite half to start doing some TMs KTMs AND Gasgas maybe a few Fantics..LOL any know if there's a Fantic dealer in the US?

Walt are you going to test the 144 cylinder with the stroked bottom end too? That would be an interesting combo..... I heard somewhere that close to square is where 2 strokes run best?

I certainly can but it will be awhile as we just got another dump of snow and it isn't going to go away for a while. I am not really willing to build a specific head spacer for a 144 so I will just have to run it with the cylinder plates and the highly advanced timing. Should scream though. MaxRpms makes that kit and I am sure that there are a few out there. Maybe someone who has one can respond.

did the math 125 bore=131.4cc 144 bore = 154.5cc 165 bore = 176.6cc can we go BIGGER?????? Walt

The bore is maxed out pretty much but there is the possibility to stroke a bit further. It would take some work on the cases and they would start to be a bit thin unless you start to compromise other things like pin diameter. Personally I think the 177 is going to be almost a bit much for the guys that like the ability to just make traction and motor up stuff easily. I won't really know until I have some time on it in the gnarly crap.

Enough with these little bikes, how big can you make a 360?


Heh, just kidding, that 360 is as much as I want to handle. Kinda makes you wonder though, hmm...

Sounds like you are building a trials engine!
I'm getting used to the 300 Beta power that wheelie outs in sixth(147lbs). To have that kind of lofting power in the tiddler would be a change in riding habits.

I like the ability to ride a gear high and still pull most anything. That said don't let my comments deceive you into thinking these don't flat out get with the program when you want to. It is just that the 177 tried to kill me initially when I was expecting about the same response as the 165.

mmmmmmm how big cuda 360 get 390- 400ish i do know a guy witha 510cc trx250 4wheeler 120bhp did it himself inhouse world record holder sand dragger his shop is full at the moment 2900 hp turbo bbc 67 nova buildin it for hot rod mags drag week its streetable its got a trailer hitch IT IS INSANE

Drawtite?

yea real tite

BUMP, because...177.

I'm waiting patiently for Walt to let me know he's got my 177 done. Once I get a few rides on it I will post a full ride review. Cant wait to rip that thing. I race my beta 300 but when it's all about fun I always ride the cr165. If I wasn't a 250 pound A level racer I would probably be on the Husky full time, at my size I can just go faster on the Beta in the races we run here in northern California. Hoping the 177 will give just that bit of extra where It can beat the Beta lap times, then I can have more fun while racing and trail riding.

Look forward to your report.
