125-200cc I Rode The Prototype Wr200 And It Is Amazing...

Krieg,

Just sent my cylinder to Walt (had been talking to him for while about this). Sent him jug, head, PV with cover plate still installed. You have to remove the linkage to get the jug off and you do not send it with the rest.

You ever ride at Brushy/Brown?

Eric

Boy I love that sound !!

I rode a 125 as a kid and now own a GasGas 200 and a WR250. I've been watching this thread because my heart favors the 125s. The problem is I'm 6'6" and 210 lbs and didn't think the 125 would be enough in the CO mountains. Maybe I should ride a 144 or a 125 but I can't really understand why a guy that wants more low end doesn't just go with a 250. My 200 is closer to a 125 feeling bike so how could a 144 to 167 change warrant all the effort? I guess dyno numbers will answer my questions once they are made available.

Thanks for the info erigre. Haven't been to Brushy yet. But I want to go. I've been pretty much devoted to riding at TNT (in Chester, SC) because my son is racing MX and the tracks at TNT are the best in the area for practice. We will occassionally to the Carolina Adventure World.

The 165 is far closer in power and how it makes power to your gas gas 200, but still rides, feels, and handles like a 125. That is the apeal and really what a 200 aught to be. 250's and larger have a completely different feel and definitely have their place and I have one and always will but 90% of my riding is with the 165.

I own a 2002 WR 125

is this bigbore kit also a posibility for this years bike?

the price estimation given by motorsportz is a fair one IMO and nothing outraguos

what would be the estimated time line when a kit is comercialy availible? (2 a 3 months)?

as I am located on the other end of the world (asia) where all this take place it would for me intresting if there is a posibility to buy the whole kit in one package, then sending my old cilinder up and down, any indcations what could be done for this situation ?

is there also some info of this kit with the TMX carb configuration?

I also need more info and would like to ride one to see if it is worth my hard earned money! Will wait for more reports to see where this goes. With all this my question is has anyone stuffed a 250 2 stroke Husky engine into the WR TC new style frame? Is it possible??? Depending on how the cylinder is done I still have my doubts about reliability and longevity, will have to wait and see!!

Wow I have missed alot. Sounds like a solid deal for a great product. Thanks Walt and MotoSportz I look foward to hearing more on this product. And eventually getting one for myself!

Robert-Jan,

This kit bolts onto 98 and newer 125's. I will let Kelly reply to the ordering process but I would expect this all to be up and running in the next month.

I bolted up a Pro Circuit pipe for a KTM 200 sx and holy batman, got back a lot of top end revs. Pulls hard to 11.5 K, loses a tad on the bottom but is still a mid-range to top monster. Power band was in rip mode from 5K to 11K for sure. The pipe obviously makes a large difference.

I wonder if that pipe would make any difference on a 144 bike???????

Walt, I just put on the Uptite 167 kit that you worked on. I was amazed on how clean the head, powervalves and pipe were. The crank was soaked in oil. That Maxima K2 is great. Does the 165 kit that you have use a cylinder spacer like the Uptite kit ? I can imagine that a kit without a spacer would have more crankcase compression thus more power. I was going to install a 14T sprocket but it appears they sent the wrong one. I need a 12T spline and this one has a 8t spline. I guess I call Hall's Tuesday.

No spacer plate on the 165. Did you remove the ridge in your head? Can't wait to hear how you like it.

have you guys played around with base gaskets for this kit yet? any feedback there?

i'm currently running the 0.3 with my 144 but have .3, .4, .5 on the shelf.

I have sent you a base gasket in the kit that sets your squish to .040". You can go to the smaller base gasket to raise your compression a bit but the best way to do that is to re-mill your head so you can get some real compression. It is currently set for pump premium. If you mill your head more you will need to run some kind of higher octane. Try it first and if you feel the need for even more bottom then I will swap you a high compression head, PM me if you want to do something.

I would invest in a better pipe before I messed with the compression. Kelly's top end is running pump gas and is actually set at only about 165psi.

Kelly,
What's your present gearing?

Have any of you 2-stroke guys used the HIGH GAIN Tuning Fuel injection kits for your bikes? It is kind of pricey @ $1300. I just wondered if never having to rejet and any performance gains are worth the $$$.
