125-200cc Just did a re-ring on my 165 after 2000 hard miles.

[Motosportz]

Bike - My 04 CR125 with 165cc kit
Oil - Amsoil Interceptor
Fuel - Pump premium
Carb - Lectron
Mileage - 2000
Type of riding - single track steep woods play riding and racing (2 ISDEs)

Bike still ran great but just thought it was time to do it. Plus as it is a 1 hour job and I have the ring might as well. First off Amsoil rules. The cylinder, power valve and piston look great. This is not an EZ 2000 miles but a slop around in the mud, climb the big hills, have a great time trashing it 2000 miles. 2 ISDE's and lots of deep woods / mountain time. I keep putting off redoing it as it just continues to run great.

So what did I find?

Plug looked perfect. Dry and tan.

Cylinder and head look very clean and nice...

Power Valves are super clean and free...

Piston is clean and ring is free. That carbon whipped right off and was not burnt on.

The old ring would accept a .024 feeler gauge. Biggest one on that set. Bet it is close to .030. The new one measures a perfect .012.

I am really impressed with the longevity of Walts 165 kit and the job Amsoil is doing. My bike spooges quite a bit, I don't care as it runs great and now looking at the lack of wear and cleanliness inside I am really impressed with the oil.

Good for another 2000 miles. Great stuff.

What ratio do you mix the Interceptor?

That can not be true Remember the Italian Factory SAID the Husky 125 could only be made into a 144. The Italian Factory said the 165 would not survive. The Italian Factory said the bike was not designed to have that big a piston the Italian Factory said the rest of the motor would fail That is what was told to me when I presented a Walt Smith 165 kit to the now ex president of Husky
Well then look at that a Crazie old mountain man in his garage built something that was said could not and would not work by the so smart motor builders in the new Italian Husky Factory

Also I have another 25 FMF pipes that are going to be shipped out today to mr Walt What would any one want with all those pipes for a motor that the Italian Factory said would not work
Maybe we should send this new found information to the new owners of Husky since the old design Cagiva based 125 motor is such a good part
Now to wrap all these pipes and wait for UPS

I am going on 3 years with a 165 no problems yet I use Lucas 2 cycle oil mixed about 40 to 1 with 110 leaded race gas Last time i checked my piston looked about the same

42:1

That is amazing. I saw Walt's earlier report with the same type of results. Very impressive guys. -Ed

Hats of to Walt and his Team!

 

[robertaccio]

not bad for .....a late eighties tech Cagiva 2T engine..(late 80s am I correct?)

Hats of to Walt and his Team!

amen. i love this motor.

You are thinking of the 250 design. The 125 was re-done in 1998 and then updated like the 250 thru the years.

 

[MotoMarc36]

Nice! That's good longevity for ANY motor, especially a "hot rod" one. I love these motors too. I certainly have been using my "old tech" motor to hurt feelings all summer, against the latest-greatest-newtech fi450s. Priceless!

 

[HSrider]

Looks really good and I just mounted up my 165 this week so hope to get the same kind of longevity out of it.

New ring added some snap and power for sure. Bike ran good as it was but for sure gained some snap. Mike got his Motosportz WB165 clone out for a ride and it is a great runner / bike too (Based on a super clean 04 CR125). What we found riding them back to back is the Doma on mine makes a lot more bottom and mid and his FMF makes a lot more upper mid and top. We both agreed for woods work my pipe makes way more usable power. His would be awesome for MX as it is a rocket on top.

So it looks like I need one of those Doma pipes.

I bet the older KTM 200 pipes might give a similar affect (will test one day soon) and can be had for cheap used on ebay. You have to butcher it up to get it on there anyways so get an old cheap pipe and make it work. Its actually really fun trying different pipes on these bikes as it really moves the power around.

 

[wallybean]

Kelly is right. The old stock 200 exc pipe does exactly that. I have an 200 SXS special parts pipe that has been converted and it is the same. Tons of bottom/mid, limited top. I also have some franken pipes that offer a lot of the same qualities. The guy that had Brandon's kit before him had it set up with the old original 200 exc pipe and said it was brutal off the bottom with all the extra compression. Mike can gain some of that bottom back with some more compression as his kit has a reduced compression head for pump gas(less than yours Kelly). If Mike wants to try one of my stash of bottom/mid pipes I will send one over.

 

[Zomby woof]

Feel free to send one over here

If you ever have a bottom/mid pipe for sale, I'd be interested.

 

[Motosportz]

If Mike wants to try one of my stash of bottom/mid pipes I will send one over.

I'm sure he would he preferred the power on my bike. Low and mid power are more useful in the tight tress and up loose slick hills we have here. The ability to swap between a top end pipe for open stuff and a low end pipe for technical woods work is a very nice feature of this durable and amazing power plant.

 

[wallybean]

When I get back from riding down south of here! I will put together some pics of the various pipes I have. They are all bottom/mid pipes. If I didn't have the auto clutch I would run one. Yipppppeeee.......vacation after 8 months on with only a couple of days off total.
