Here you go Daz, if the rumor doesnt come true...go with this...

New Speedmaster Wiseco 988cc big bore kit

that would be nice...it would probably be hard finding a shop to install it properly though...

my guess is maybe 2 people actually do that...if that many. probably none.

Wonder what the stroker crank and rods cost? Nevermind boring the cases out. Throw in the headwork, cams, exhaust, carbs, and I'd bet you are out to 8500 dollars, plus the labor for a complete rebuild. What, nearly 10K total?? Wow. It might be worth it if you did your own work and started with a flogged old Bonnie from the boneyard.

Maybe if I was a machinist and lived next door to an engine builder, and throw in a mechanic neighbor from down the street, multiply that times all the beer I'd have to buy....

shei1t, it's still too much money and work...

You could probably buy a used crotch rocket for the cost of that stroker engine.

I'm into performance mods, but that is rediculous.

If the 988 has a longer stroke, both have same bore, how could they both have same compression ratio?

This is copied and pasted from another forum. This guy instaled a stroker kit on his bike along with alot of other mods as well.

I did play around with a custom V-Twin probably a S&S powered Big Dog on the I 95 and I had no problem staying with and accelerating quicker from 70 to 90+ or maybe 100+ while passing on the intersatate. He was always attempting to pass me and always behind me until I made my exit when he blew by still accelerating.

Throttle response is also a dramatic change--the rpms hit harder similar to the race bike--but a new clutch is definitely needed--the increased torque is causing slippage anytime you hammer the throttlle. The Barnett kit had about 22k miles --I did not change it because I saw no excessive wear.

This bike has a pile of money in it from appearence, and it's not all in the motor. There was also headwork done to this bike as well.

Shorter rods and, possibly modified pin location or crown configuration.

I don't think it is worth the money to do all that work to a relatively new bike. I agree with mecchanica that it would be with an old boneyard bike. If you are gonna spend 7 to 8k on a new bike and then spend another 2k-3k on re-building the engine just to get 130cc's, and hope it is actually tuned and sync'd right, you might as well just invest all that in capital cost and buy something brand new with a bigger engine. If it isn't a Triumph, oh well. That is their fault for not making a cruiser bike that competes with the rest of the market.
