GS1000 1100cc bore

[Guest]

Hi all, not been on for a long time .
Just to let you all know, I've put one of the cheap 1100cc kits, off eb**, in my GS1000 and I've done a good 500+ miles and it's working great . Well worth the cash.
Item number 261297544129 (I do not have anything to do with the sale lol) just passing a good thing on

Interesting, good to know. Thanks for posting. The gasket seems to be holding up as well?

[Wraith]

Yes very well, no leaks (up to now as I dont want to temp fate)

I know the bike is running fine but how did you find the quality of the stuff?

Very good, I'd say as good as OEM

How noticeable is the performance difference? Is it torquier or faster on top end?

[Wraith]

They're not a high compression kit, just a standard compression. However there is a noticeabe diference in bottom and mid range - more power and torque - as you'd expect from a bigger bore. I wouldn't say that it compares to one of the Wiseco (etc) full performance kits, which are high compression and will give better all-round (including top end) power and performance boost (albeit power = torque x revs!) but it's a lot better than the original engine was and great if your engine's a bit tired or needs a rebore. I use it on an everyday commuting bike and even on shorter and slower journeys it's definitely reminded me of how much I like the torque of these big older engines
I did have Wiseco hi-comp 1100 kit in my other GS1000 and so I do have something to compare against.
Also, I haven't had to bother on this 'standard' kit of messing around with strengthening anything, hi-comp gaskets, studs etc.
I'm using CV slide GSXR1100 J 34mm carbs by the way (and K&N individual filters) with a Harris Works exhaust - seem to be working well.

Thanks for the info, much appreciated. If it doesn't cost all that much to get the heads readied for that kit, it sounds like an affordable upgrade.

I have a stock 78 1000e (26mm carbs) and I wish it had more punch than it currently has. Since all my mechanical expertise is just what I have picked up here, I need to also keep it simple.

I don't know how much it will be over there to have the bores done, but over here in the UK I got the bores rebored and barrels and head skimmed for £140 by a small engineering business who specialise in car and m/c engine work. I'm told it's about £20- £25 per bore.
