Any ideas on TRX-1 jetting

[air4ce1]

2003 rear mount turbo, RX-1. I initially put it in the shop 'cause it was way lean on the bottom end. Had to choke it to get it smooth, but it was great when you punched it wide open.

Shop changed the jets and now bottom is still sluggish and the sled has lost the responsiveness it had (use to be instant).

Any ideas on the jetting set up or even which size to go with. We ride mainly between 7-10K, and I'm running 50/50 with 91-110 for fuel.


Thanks in advance!

does it have a pitot tube? if so I have found that going to large on the pitot tube jet size greates a nasty low end lean spot, I ended up going down to a 110 jet in the pitot tube to keep the throttle respone and get rid of the lean spot, becaue of the small pitot jet size though I ended up at 100 mains to get the a/f ratios into the high 11's low 12's

What system is it? As asked above does it have a pitot? I have 132.5's in my Bender rear mount. Running at 8-11k on pump gas.

Bender rear mount. There is a pilot so I'll start with these and see what we can do.
Thanks

Mine ran pretty good with 127.5's in it and the pitot tube blocked off . 3-5000 feet .
