Is it worth working a 200X?

**chris200x** · 07-13-2005, 10:52 PM

Would you be kind enough to go into some detail about what kind of motor work you had done, race setups and such. Ever had problems? Anything like that.

**catfish** · 07-13-2005, 11:14 PM

I sent you a PM Chris.

**vartiak15** · 07-14-2005, 08:18 AM

how do you advance the timing? i would like to do this.

**250r'en +TCB** · 07-14-2005, 09:34 AM

Honda engineers build there products to last, if you were to go ahead and bore it, performance pisto and rods, you are basicly telling all theose engineers to go shove it. But when you do that, the engineers get to come back in a short time when your engine blows and say "Told you so B****!!!!!".....................funny but true

Catfish, may I have that pm as well?

WTH is up with all this engine blowing stuff. The 3 I tore apart were pure lazy I dont want to maintian my trike. Fork oil that smell like, hell i cant even begin to describe the smell. I read through these forums, hey I have the best running such and such, runs like a raped whatever, oh she smokes, but hey its strong so who cares. Quit cutting wires, because you lose spark. You want a good runner, change that 20 year old chain and sprockets. Dont believe me ride it with the 20 year stuff then ride it after. Change those bearings. Clean your airfilter, clean your jets, make sure your oil is change and running through the engine. I am more apt to whoop on you if you dont have a good maintianed trike.

This is extremely well said

you can build any engine and make it reliable or unreliable. you can take a new 450 whatever and slap a new pipe, cam, air filter on and NOT re-jet the carb and make it unreliable. of coarse you can do all that and re-jet the carb and make it a reliable monster. it really, really becomes important to measure everything for tolerances when you are building or rebuild a 20 year old engine cuz garunteed there is gonna be something outta spec. I'm having my 200x engine profesionally rebuilt right now and I have to have the valve cover and the head mating surfaces milled so the surfaces are flat again.

then I have to have the cam journals re-bored so they are round again. My case halves have to be milled as well cuz they are warped just the tiniest of amounts but it's enough to throw everything out of whack if it was put togethor that way.

What i am trying to say is a high perfomance engine can be very reliable as long as it is built correctly. don't put a 12:1 piston on a 20 year old bottom end cuz it won't hold up to that much firing pressure. if you build a race engine get everything measured and get everything back into tolerences.

A full bore race engine will always be kinda finiky with tuning but thats the nature of the beast. build a stock engine and you break it in and set the jetting once and more than likely never have to touch the jetting ever again if you dont really leave your riding area..

There was a time when people built up a certain model in order to comply with class restrictions for competition. Ill never understand why somebody would spend $2000 on a 200X trying to make it run like a 350X when they could simply get a 350X, unless you are racing in a 250cc 4 stroke class or something that doesnt allow a 350X.

In my opinion, why waste all that money trying to trun something into something its not, when you can buy an upgraded model for less money, and you arent destroying a classsic original?

People always talk about how fast modified Blasters can get, and they are right, but a highly modified Blaster has only one purpose, and that is to race in a Blaster class. Highly modified Blasters do have serious reliability issues when compared to the nearly bullet proof stock Blasters. Anything that works a motor harder will make it wear faster, and some motors just werent meant to handle the kind of pressures put on them by soem builders. Many racers are rebuilding motors every couple of months. Some highly modified Blasters were faster than my stock TRX250R, (though they had inferior suspension systems). The major difference was when I got done racing, I could go ride miles and miles of trails, or go run cross country harescrambles with no worries. You dont see stroked and big bore Blasters doing the same. You build a Blaster to race a Blaster class. If you build it to be a 250R for typical use, youll be disappointed, and have tons of money invested in something you cant rely on.

If you want to dump a lot of money into a 200X so you can run it in a 250cc class at Trikefest, and have a mechanical advantage, go for it, but if you are just looking for better performance, save your money and buy a better performing model machine for a fraction of the cost.

Well said Tim Sr...

i've thought of building my 200x so it would run with bigger bikes but i figured by doing that i could have just of easily sold my bike and bought another one that would run better with more reliability.

I am happy with my bike for what i use it for...trail riding and some mild motocross

If you dont like your bike just simply sell it and buy a new one

**greenhuman** · 07-14-2005, 09:54 PM

The problems people have with reliability is they stay with the stock stroke and have to rev the freckle out of them to get them to go. A 64mm short rod stroker from Powroll which will come with new rod, pin, bearings and timing sprocket and is balanced combined with a 65.5 or 66mm 10.5-1 compression Wiseco piston, 28mm carb off a CR80 or early 250R, a Dg full system and a mild drop in cam will be super reliable, go like a b*stard and give 250R's and a lot of other things the fright of their lives. You do not have to rev it hard but if you do everything will hold together just fine.

Wow, wouldn't have guessed a short stroke to be the problem, all the new hot motors have shorter stroke to bore ratios then the 200x did.

**jakey** · 07-14-2005, 10:10 PM

greenhuman i think the main problem people have is that they do not want to go "all out" on building a bike...instead they drop in that high comp piston and think that's going to be exactly what they needed to beat that 250r in a drag...but realistically to build a 12.1 motor reliably it would cost you 500-700 dollars

**catfish** · 07-14-2005, 10:41 PM

You also need to look at the stroke to rod length ratio. A shorter rod puts more piston loading on the thrust side of the cylinder wall. In other words, the angle of the rod tends to shove the piston into the cylinder wall on the thrust side. If my memory serves me correct, Powroll years ago went with a shorter rod and a big bore ( still keeping under the 199cc limit) and they just wouldn't hold together. They revved to the moon and would absolutely fly, but they just couldn't handle the big flat tracks. Now they offer the same stroker as Sparks and TC done. Same rod, but with the crank pin moved up on the crank, much more reliable. For me, building an X motor all out is just re-living the old days. I agree, if you want to have something fast and reliable, just save up and buy one of the new generation 4-strokes. They are a totally different engine than the ones years ago. The old ones can still be built right and reliable though, you just have to make sure everything is up to code. And I'm not trying to back out or anything Oldschoolin, I'll still meet you at TF next year.........

LMAO, AWESOME! Nothing better then some good ol' ball busting.

**200xadam** · 07-14-2005, 11:27 PM

i think that if your going to make a little machine into something bigger you should know what your getting into. my 200x isnt even running yet, and i have a good 300 dollars in the motor work alone..and going into this i knew i was creating a monster that wasnt going to be as reliable as stock...and i would never get my money back from this. but im creating something that is going to do exactly what i want it to do. i want it to be the fastest 200 4 stroke that people see... i want it to shock other riders when my little ole trike pulls up next to them and actualy gives them a run.

its all about a thrill to me. and when im rideing next to a bigger bike and watching them slowly fall behind me...it suddenly all seems worth it....

I'm sure it is quite satisfying to have a "little" machine out run a bigger one but that's the motor doing it and not you. Really, anyone can twist a throttle and motor away and I have never been impressed with that aspect at all of seeing who can go the fastest or who outruns who (just not mt bag).

What impresses me is the skilll of the rider negotiating the different obsticals that you encounter on the terrian you are riding on.

You can hop your machine up 10, 20% or so but if you don't know how to traverse the terrian it won't do you a heck of a lot of good.

One easy hop up (and I'm not pertaining to anyone in particular) is if your over weight and can drop some pounds that ='s to the same thing as hopping up your motor and it's free!

Another way to lose weight on machine (if your not going far) is always just run a 1/2 tank of gas. Why carry around 6-7 lbs at darn close to the higest point on trike, when you don't have to. Not only is it lighter but lighter at the most important section of machine which lowers the center of gravity a bit.
