    what would you do or should i do? 720 gti

    hey everyone, this is my first post here on the forum. ive read a lot of info on here over the past year and feel like im in the right spot. I own a 1999 gti with the 720. im on my 3rd engine (1. original 2. crate that the shop screwed up 3. I built myself) and ive owned this rig for about 8 years. I have always wanted a little more out of it but the performance for the 720 seems a little lacking since the 4 strokes with turbos and superchargers are out.

    I bought a new solas concord 14/22 impellor to put in it and am replacing the bearings also. I plan to run It this year but id like some input from yall. would you look for another ski to upgrade to? modify this engine or look for a later model salvage with a good engine and convert it? im kind of partial to this one bc its paid for and ive worked on it a lot. im a little bit of a gear head so I would be willing to take on the conversion if its feasible.

    I look forward to hearing from some of you and learning the ropes of the forum.

    Don't mod it!! you won't get much gain out of it. I would say either keep it an ride it, or sell it and upgrade. I wouldn't attempt a conversion either. With the money you would spend converting yours to a 785, or a 951, you could buy a newer ski. Look for a decent four stroke or a well cared for two stroke. Sell yours while its worth something. I've got several skis that I'm attached to that I should have sold years ago before they lost all value.

    yea I book valued mine the other day and it only came back with 1800.00 and that just seems a little low. id rather keep it and let the family ride it since ive been through it and buy a newer one for playing. just thought id ask someone who actually deals with these rigs more often.

    thanks for your input Pacer!!

    the best way to get more out of an old two stroke?

    lose 20 pounds

    the speed gains are enormous.

    In all seriousness the cost/performance curve just isn't there on old two strokes.

    Enjoy her for what she is and if you want far more speed and power, go with something appropriate

    I put my new solas impeller in and replaced all bearings in the propulsion unit. went ahead and put a new wear ring in too. my old one didn't look bad at first but then I found 2 or 3 big holes in it and it was pretty rough. so hopefully this will help with the rig some this year.
