Question trinity racing 700 big boar kit???

my buddy asked me to post this up and see what's everyone's opinion on it. he has all the bolt ons already and needs more power but doesn't want a rotax swap.

any good or bad things with this kit?

any other kits he should look at into getting?

thanks in advance.

X3 for Benchmark. I've read horrible things about Trinity except for their spindles.

There is nothing wrong with the Trinity 105.5mm jug and piston combo (big bore kit), it is NOT unreliable. That being said, the price/performance isn't there unless you do a host of other upgrades to take advantage of it. Even then...

There is a ton of power to be made with the sb/ss setup, and has been mentioned either Weller Racing or Benchmark Performance can help your friend with the parts needed to make a big difference without increasing bore size. If he's already done the "bolt ons" ie. intake/exhaust, a good fuel controller would be the next thing. And by good I don't mean the current MSD... The future MSD perhaps, but there are better options available right now.

Either company mentioned can do great port work on the cylinder head and have the throttlebody bored, both upgrades will yield good results for power. A good camshaft will allow the upgrades (intake/exhaust/portwork/throttlebody) to shine. And by "good" I mean a Hotcam raptor stage 3 (or rhino equivalent check cam specs to be certain) or better. These are long duration cams, build good power in the upper rpms, but lose a little on the bottom due to trading off lift (making it easier on the valve springs) for duration. To get the lost power back in the lower rpm range, you increase the compression. If you're sticking with stock bore, there is a company that has CP custom make an 11.5:1 piston (102mm) with a corrected deck height available for sale. And it's premium pump gas friendly at sea level, fly cut for up to 40mm intake and 34mm exhaust (stock is 38 and 32).

Personally, I'd do these mods instead of the big bore, more bang for the buck.

Feel free to mock me or disagree with me, I don't have all the answers, just opinions
