do it on a track, then it's up to the riders. Xr100's are known for not having much power, infact thats why they are so reliable. They dont produce enough power to break themselves

35-150 psi.  Start with 40psi and tune from there.\n\nCheck this pdf out:\n\nhttp://www.kleinbikes.com/assets/asset_upload_file610_1187.pdf\n\nTable 7 at the bottom.

I work on these for a living.  Pound for pound it is the Honda TRX450R.  No doubt (stock, of course).

take off your cranks and tighten everything and oil it all. this will make it run smoother and your parts wont come lose, maybe get a new B.B. if that one is old. Tighten that lock nut realll good and you will be in good shape.

You need a timing light. There is a nut under the distributor, loosen it and point the timing light towards the lower pulley in the front of the engine. There should be a timing mark there. Set it to factory specifications. \nTurn the distributor slowly when you change adjust the timing.

The simplest and least expensive way is to drop the forks a bit (that is, raise them in the triple clamps), increase the rear spring pre-load, and shave some foam off the seat.  However, those suspension mods will affect handling (sharper steering and stiffer shock action) -- but that might be okay for a learner (if she's not going very fast).\n\nThe next step up is to take your suspension (front and back) to a motorcycle suspension shop where they may be able to reduce the effective ride height of the forks and put a shorter shaft on the shock.  However, I'm not sure that's possible with the stock shock on a TTR230...  Those mods are somewhat pricey though.\n\nYou can also look into lowering linkages for TTR's, though I haven't seen them myself.

Try a company called Racing Beat.

Dihatsu .2 liter weedeater XP90, yea she runs on a 20:1 gas/oil ratio, got her up to 26 mph going down hill, shes pretty sweet, Id take u off the line, but I think you have me top end, get a life\n\n--truth is son, I run a new gsxr750, it does 188mph 600 from redline, but any retard can go in a straight line and mash the pedal, but, where technique really counts is in the mountains and on the twists, in which case son, you would be eaten alive, and guess what, i spent 60000 less than you...now whos the tard? hahaha

I would just run it at 60 Hz. Output rpm will be 20% higher. \n\nAlternately, you could get a 400V VFD and set it's output to 50 Hz.

good carb  probly an 800cfm  the two screws in the front / bottem of the carb with springs. work slowly and at idial speed in 1/4 turns or 1/2 turns or one full turn.\n\nturn one screew in (tight) a 1/4 turn listen to the motor go another 1/4 turn lisen for a change do not ever rev the motor....wait be patient.... go another 1/4 never loose track of your starting point  whitch is 3/4 turn now\n\nwhen you hear a change in idial losen it a 1/4 wait some more\n\nnow do the other screew the same. I\n\nf the factory lock glue is still on the screews dont touch them\n\nand this will not save you gas

To start, I'm not a "tuner guy". It seem one would want to istall a performance exhaust to allow more air flow and a computer reprogrammer to override the fuel efficient factory settings. These things alone will gain you maybe 40% more horsepower. Tuning the suspension is a big next step to get the most from your newfound power. \nThere are tuner shops who could give you lots of tips on performance or try this site. http://importtuner.com\n\nGood Luck !

Talk to your dealer and find out what the ways that you can do it are.  Nice work on getting into that one.
