Did you measure the piston on the right place (the skirt) ?

Where does this story come from ???

Honda CRF 250 has a bore of 78 mm Montesa 4RT has a bore of 76.5 mm. So it will not fit.

If the bike is ready Bou and Fuij will ride a new bike next year.

Yes they have conventional damping with compression/rebound controlled on both legs.

I think they have problems with the ignition. There are several films on youtube, but they never ride against the big rocks, and if you listen to the sound of the engine ... it is not that snappy as the Beta's, or Sherco's. It will take some time for that, there are a lot of parameters to find out. For the clubmen rider it will be enough, but they will compete at the top in the world championship, so they still have a lot of work todo.

i can it remember too. I found the test in mine archive : RTL DirtBike review

This is NOT true !! Basically the the dual and single map files are equal. There is a little difference in the ROM of the ECU so also in the file you are uploading, thats why you need other software 05 settingstool for the single map and 07 settingstool for the dual map. The lead is usable for both PTB's

Hi check your gascable the throttle must be 100% closed, try agin with some space on the cable.

Yes different mapping. I have the following body numbers: 16400-NN4-315 Single stage body 16400-NLC-003 Dual-Stage body 16400-NN4-602 Std body 2005 from my own bike 16400-NN4-603 Std body 2006 or 2007 i'am not sure There are a lot of different numbers for the standard body's, so it is difficult to say which number belongs to which year. Also the numbers for the remapable body's are changed.

Make your own, it is not difficult

Road bikes have a fuelpump with much more flow and more pressure, i have searched a long time but couldn't find one. Perhaps somebody else knows something.

Did you check the temp sensor in the radiator, because if this fails the ECU is resetting and engine is running at low level.

Mitani bore is : 80.5 which give 275 cc S3 bore is 80 mm which give 272 cc

thank you Franck, but you have also made a lot of nice things ! modification of the chain tensioner, your fuelpump bracket, pressure regulator etc, etc....

Hope this helps.

You are right only for road use (it is new from the 2009 models). Thats why they have a kit to change/transform the bike for competition use http://members.quicknet.nl/sw.zeinstra/4RT...ll_power-uk.pdf

Do you know someone who knows what he must do, and who can tell the secrets ?? I haven't met some one. I know only one person who made his own maps the rest is only talking about it and collecting maps.
