Default 88ci kit...anyone have one?

Looking to do the NRHS 88ci kit on my X1 with a set of XL1200 heads. Anyone have any input? Hopefully ordering the kit soon and will start to take the engine apart to get it machined by the end of the month.

THANKS

Here's the answer, you can't beat an 88" big bore kit for the money. They rev and they make power, anywhere from 110 to 130+ hp depending on heads, cams and exhaust. They're all bad to the bone.............Steve

Nice! How's that exhaust working for you? I'm using Force Exhaust and had to fabricate goofey tab around baffle to get back bottom end, cost me 2 HP on top but gave me almost 4o ft lbs off idle... doesn't sound just right either.

Used Super Trap on my 2 stroke race skis...pain in the ass to keep disks clean though on 2 stroke...

Be good,

Billy

I wish I had made the head pipes 1 7/8" instead of 2". It gained 2 hp @7100 but lost almost 5 ft lbs @ 4500- 5500 rpm, Ain't that the way it goes? Still I like the way it looks and the sound rocks. Next exhaust will be a shorter 2-1 with open reverse cone megaphone, sorta like the one on the "hammer" in this pic.............................Steve

Actually I paid 6900€ (Around 8000$) for my 88" Buell M2 conversion.
But almost everything from bottom to top has been renewed,
upgraded or reinforced.

My 88" Cyclone is really a dream to ride.
Pulls like a traction engine,right from idle.
150Nm around 3750 rpm.
Smooth in any rpm.
Could ride her forever.
