Open spaces mostly. I'll look into some wheel spacers and I'll give jetting the carb a try. Thanks!!

So should I get it to where I have a higher top end?

Wiseco 10:25:1, punch it out a bit, cam, valves, valve springs, port and polish the head, sprockets. Should wake it up a bit.

Once again more talky talky. You fools keep telling people to take their engines apart after he already clearly said he does not know how to JET.

I implore all that suggest motor work to prove they did the work, show what it cost, and post a current bid of it running properly. Don't forget to prove that its faster than stock too.

Leave it alone and RIDE IT. When it breaks, then you learn.

So many people here spout off about rebuilding engines. Hardly EVER do we see a finished engine build here, and this is why.

Don't tear your engine apart if it already runs good. Unless you are willing to accept failure and lost money. Not saying you CANT. Saying you SHOULD NOT.

200x350xtriZ250 has the right answer here. Start small people.

I just built a 200x motor. No stroker crank but wiseco 12:1 piston, largest cam webcams inc offered along with the heavy duty valve springs, titanium retainers and steel base washers. Also have a ported head.

Hows it run? Dont TELL ME. SHOW ME.

Who ported your head? What are the flow numbers? How much did they increase the flow at .400 lift?

Which model cam? What's the lift, duration, LSA on that?

What did was your valve stem to guide clearance?

What did you set your ring end gaps at?

What jets are you running?

Anything else you can TELL us?

for the money sped on making a 200x have more power you can buy a 350x....been there, its really not worth it.

Best bang for buck is finding a used XR200 cam and a XR200 carb and an exhaust...that alone will set ya back $300 prob.

x2

Do it and you'll never look back.

I'm not a 200X hater. I had 2 nice ones for a while. Once I bought the 85 250R and finished the 85 350X, the 200X's never got ridden. One sat for a year gathering dust before I cut the cord and sold it.

Excellent trail machines but not enough Wheaties for my (m)ass in the sand and not cost effective to hop 'em up.

I had 6 grand in a 200x, it was still slow...a 125 2stroke eats them. sad but true. IDK what you do to them...big motors rock, smalls ones are for play.

Only you can answer that. Be honest with yourself before changing anything. Where/when you ride do you find yourself in high gear and wide open throttle for long periods of time? If so, then yes I would start by going up 1 tooth on the front sprocket. If that helps but you need more try going up another tooth if available. If you can't go bigger on the front, you can go smaller in the rear maybe to a 36. Changing 1 tooth size on the front is equivalent to 2 or 3 teeth on the rear. Stock sizes are 12 or 13 up front (not sure which) and 40 in the rear. I think the max size in the front that will fit is 14 or 15 (again not sure).

If you are serious about other changes that will require rejetting, I'd start by getting those parts(exhaust, air filter, etc) as well as a carb rebuild kit and some larger main jets. Stock main for the 200x is around 108. You should be able to find a set of 5 mains that include 110 112 115 118 120 or so that will give you plenty of adjustability.

I briefly scanned both helpful posts above and just want to note that the largest front sprocket to fit a stock engine with case saver in place is 13. Stock is 12
