For those who've had the experience... How much different does 100cc's make?

Can you upgrade every Thunderbird engine to the higher displacement version?

I really like the Storm, but they seem to be a whole lot more difficult to come by...

So the timing of your question is perfect. I have a 2010 Thunderbird 1600 and it has about 32,000 miles on it, and for a variety of reasons I can go into on another post when I have more time...I'm upgrading. TODAY I purchased the Big Bore kit and am having it shipped out...when it gets here my shop wants to take a look and make sure it's complete, and then I'm scheduling having it done. As for worth it...I have read lots of forum posts about just how much better the engine feels, not just performs. I have a Power Commander V on mine already so the shop will just tune it on the dyno to break it in...so I will have before (1600), and after (1700) dyno graphs to compare.

I've ridden both and purchased two 1700's. I can say I could tell the difference and was impressed with the extra 100

Bad news here...I just got emailed that the Big Bore kit is no longer available from Triumph. I tried 2 places online that showed to have it "in stock" on their shelves, and got the same result from both of them. The place I ordered from, refunded my credit card. So now what?

That's just the problem, my bike has the infamous anti-freeze leak anytime it is ridden even moderately frisky (3rd gear, rolling on and off throttle from 3-4K rpm corner to corner)...EVERY SINGLE ride it looks like a elephant sneezed on my manifold behind the cylinder heads, I was going to finally have the shop mill the heads or whatever is needed to fix this problem once and for all and combine that with a big bore kit...I guess I will just spend the $$ to get it fixed without the benefit of an upgrade...seriously thinking about selling her and getting something else.

IMO u r lucky it was out of stock. I have a Tbird i bought new in mid '09, pre order bike. Have 80,000 plus on it now and got the BB kit at 12,000. Soon after it was installed the knocking started. If u haven't read about it the 1600s rarely have the issue but a lot of 1700s do because of the bore./piston geometry. Piston slap from most accounts. It's ruined my enjoyment of the bike for many years. Don't do it ! Even if your chances of not developing the knock are better then having it, it's not worth the chance. Second, the power gains are not huge at all and probably 90% of the gains are not from the extra 100cc but from the cams. If you can find a kit i would just put the cams in and run a 1700 tune. But do yourself a big favor and don't have the kit installed.
