I bought a TRX 3.3 brand new and did the break in procedure like the manual said. Now I am having some tuning trouble. I just cant seem to get it to run right. At full throttle it sounds likes it going to stall. According to the manual that means it needs to be richer but I have tried this with no luck and I have also tried adjust the low speed needle with no luck.

when your dealing with high end performance then you adjust the hsn, not lsn. it could be a little rich. how much smoke is coming outa the exhaust? if theres next to none its lean and vise versa. it could also be your engine is still waking up. run a few more tanks and see how it is, if its still the same then try tuning it

set it back to factory and start from there....its all in the manual....tune the HSN first then the LSN.

I do adjust the HSN first. To make it not bog I have to have quite a bit of smoke coming from the exhaust.

sounds rich...the factory settings are pretty rich so dont be affraid to lean it A LITTLE BIT...dont go overboard or that engine will be a paper weight 3 gallons later

if it cuts out burping its too rich, if its reving like crazy and stalls its too lean
