125-200cc CR125 project in Dirt Rider

Maybe Wallybean should send him a 165 kit.

He isn't even using the 144! I suppose there are a couple 125 purists out there but he needs to report to the public how the 144 works. And, if they developed the pipe on the Dyno, why no numbers??

Love the corner bumpstart lol.

I can't get the link to work

125's rule!

My friend Dick got lapped by Jimmy on that 125 in a 1.5 hour GP at Washougal this fall. He couldn't believe he got lapped by a Husky 125, he pokes fun at me for riding them and was on a KTM 150XC at the time.

Later,

Man, a 165 with a smartcarb could just rule the 250 class

Lots of guys like the way a 125 / 144 revs... The 165 has WAY more useable power, but doesn't have all of the top end the smaller bores do...

Blake,
It will be interesting to see if the smart carb and a rev'y pipe gains that top end back.

I haven't been following the smart carb thread.... But I'd love to try that HGS pipe again with it sealed properly, on both maping modes...

I think the problem is simply that you are dealing with the same porting as the 125. My next deal is going to be sending my 144 cylinder to Eric Gorr for porting while I install the real WR gearset.

Wow Doug,
What are your goals with that direction? Just curious. I personally don't want more rev's as you know.

Walt once Kelley is done "testing" my SmartCarb he's sending it to you for testing. My WB165 with the SmartCarb now revs like it did in 125 trim. It's crazy I know but that's how it feels to me. My son always liked my Husky in 125 trim even over it in high compression 144 or WB165. Now he's all over my bike again because of how fast and hard it revs with the SC. Can't wait to read what you and Kelley think.

Hi Walt,
I'm looking for more midrange to top end. I really like the better throttle response I get with the CR ignition, I just want more hit from the 144 cylinder.

I would see if FBF would be willing to work on your cylinder. They have ton's of past experience getting the most out of these cylinders. JMO.

Thanks, but I've had Eric Gorr port my cylinders since the 1980s. I've also got a highly massaged 2001 YZ250 with a YZF450 gearbox and 2007 dual chamber forks. I used to run a heavy flywheel to slow down the MX hit off the bottom but it still took a lot of throttle control in tight sections. I sent him my cylinder which he decked to lower the exhaust port and then relieved the head to return compression back to stock. He also ported the exhaust, transfers and intake. I no longer use a flywheel weight and now it is very smooth off the bottom and transitions into a nice mid range hit. Exactly what I wanted.
