125-200cc Another possible 125 big bore option

Now that would be cool. Can you imagine a 200?

Hmm

Hey I am all eyes. I just contacted EG on his 144 kit so let me know what he comes up with, thanks.

Husky is pretty much a copy of Yamaha 125..... maybe he can do a 167 stroker like they do for Yamaha 125's?

Stop hitting your head on that wall or it won't ever come to you LOL.

I believe Uptite does this one. It is overbore only

George makes a 167 kit

You are asking for a ticking time bomb with an overbore that big, IMO. But what in the heck do I know?

its a 2 stroke, they are going to blow up anytime anyways.

The 144 BB kit isnt rocket science. I have a puked CR125 jug sitting at Bondi Engine Works in Toronto right now seeing what they think they can do with it.

The 144 kits have been out for a while now and certainly boring out a cylinder for relatively cheap power gains has been going on for many years. The best part about the Eric Gorr kit is it is a Quality piece for a good price. If it wasn't a viable option for more power with minimal input I wouldn't think Husky would be offering one in the near future.

It certainly looks like there is room to bore the husky an additional 2 or 3 mm or better yet a re-sleeve and stroking the crank is pretty straight forward just spendy without your own lathe and bore machine.

Get her done Kelly you won't be disapointed.

I believe that EG also offers a stroker that goes to 151?

I have to say again that I am really impressed with the way the 144 runs. I may experiment with some spare power valves over the winter to enhance the mid-range for the dry washes and desert riding that I hope to do this winter. For the tight gnarly crap we have around here I will keep it the way it is now.

I look forward to thrashing this scoot for the next couple of years until the new FI 200 comes along

Not if it is a Husky My 2006 CR 125 has 4 years of racing and never had the lower end apart.Just had George from Uptite install lower end bearings and all is good again PLUS it is still on the stock bore
This bike has won many expert class desert races ,plus 1 National AMA Mag class champship
AND now my son Matt has enought points to take home the # 1 plate
for the 2009 AMA National Hare and Hound 125 expert class

Only one more race to go this weeken round 8 so a big National # 1 for a STOCK Husky 125 AGAIN same bike i rode last year

Two factors which limit how big one can go....bore and stroke ratio...and how much counterweight can be built into the crank...the heavier the piston... the more counterweight needed to offset its moment of inertia...or it will be heavily limited in max rpm...or it will go bang.....

Most two stroke manufactures like to stay pretty close to square with regards to the bore and stroke....and dont like to stray to far from it say 10 or 20 percent or so.....as you start to lose the crankcase compression effects with large bore short stroke....

The real answer..???? A "slightly" larger crankcase much smaller than a 250....but one that accommodates enough room for proper bore stroke ratio...and more crank weight......suitable for up to 200cc...and I dont mean the current 200cc bikes(from austria and spain) which are based on a 250 bottom end.....


But I dont think we'll ever see it.....as there is little interest from the race department for an intermediate size.....

But remember the days when 175cc was very popular......


But I think I'll stick with a 125....and try a 144 kit later....
