thanks for commemts. i am told that i can go to 1108cc big bore that will give me more torque as that is what i need for hillclimbing,but i don't want to mess up a good sealed powertec motor if there is another way of doing it,anybody know how much it will cost,problem is i live in jersey ci,and my radical is the only one over here. thanks people.
For it to all make sense, you need to be looking at it as a complete package; stuff like 1109cc big bore, gas flowed head with three angle cut seats, high lift cams, slotted cam sprockets etc; reckon you'll be looking at a 'laying on the builder's bench' cost of about £1500/£1750 + Vat, so therefore plus cost of engine out, over here, back there, engine back in.
Splitpin, by the time you look at the cost of the full strip down & rebuild with over bore of the barrels & re-plate + oversize pistons / fully gas flowed head / cams / lighten polish balance crank / general consumables etc I would of said you are more likely to be in the £2750 - £3000 + Vat ball park to be honest.
Top choices are Mistral Performance (Rob on 01702 541421) or Powertec as already pointed out above.

Have you thought about selling the sealed Powertec 1100 and fitting a stock ZX14?
If you budget on a net £2000, that should get you a crashed bike (sell the bits you don't want) and pay for the installation. If you then knock off what you get for your 1100 Kwakker, you should be a happy and fast teddy.
Angus has done it and told us some of his secrets here: http://www.pistonheads.com/gassing/topic.asp?h=0&a... to ZX14 Conversion

extreme engines have a ready reckoner quote generating thingy on their website.
I am in a similar position and have to say that after a lot or research I keep coming back to the position that more power means ditching the ZZR engine. (Though I am still toying with the idea of forced induction) If you add the cost of a rebuild on the ZZR to the price you can get for it un-rebuilt you are about at untuned busa or zx14 money. Conversion costs are not inconsiderable particularly if you want to go dry sump but the benefit is debatable.

holy s
t,you guys are good at info,maby if i sell both my 1100 powertec engines i might come up with enough money to get a motor with more grunt,this is a good one i live in jersey no vat and my living is livestock transporter,and i have a holding yard in newbury,so i am back and forth like a yoyo.any of u guys fancy doing a jersey hillclimb next year give me a shout. its a bh of a hill.

Call Karl at Extreme I am also in the same boat looking at getting more power out of my engine for next year ZZR1100..
I think with a 2mm overbore and 3mm crank, high flow head, race cam's, good carbs, a real 190 bhp should be achievable, with good midrange torque.

What sort of cost do you reckon for that lot?I think with a 2mm overbore and 3mm crank, high flow head, race cam's, good carbs, a real 190 bhp should be achievable, with good midrange torque.
Not cheep but still a lot less than a engine conversion.. 3mm Crank is $860 exchange, you would need forged pistons and steel rods £900 for both, £400 for the head porting, Cam's are either £2-400 for kent version or $850 for the muzzy race grind exchange, rebuild is £750 unless you can do it yourself?
your talking £5K for busa conversion and then you would only have 170 bhp, you would need to spend another £2K to get back to the 190bhp which could be got out of the ZZR1100?

thanks guys for all your input,one more ,can anyone tell me if a flatshifter will improve the car for hillclimbing if so which one is the best?
Hi DaveNice to see that ? has gone.
Hopefully, both Angus Buchan and Lindsay Mercer will be looking in soon. Both are a couple of the Top Guns when it comes to launching a Radical up a hill; for example, Lindsay holds numerous Class Records all over the place; he's got a 1500 Prosport (nicknamed "Black Betty") with all sorts of trick aero and engineering that he's carefully purpose developed over a long time specifically for the task; I'm sure that last time we spoke he said he was achieving 4G under the brakes
Great blokes and two of those people you've got to admire; guys who spend enormous time, effort and expense developing stuff and are then quite willing to share the benefit of that with others. Lindsay uses a Trickshifter (same components as Flatshifter from what I can make out) on the stick and appears well pleased with it. If it's good enough for LCM, it's likely good enough for everybody putting a Rad up an incline. Angus has put a ZX14 in his 
Like they say, watch this space. I'm sure these guys will prove to be the font of lots of knowledge for you as you start to forward .......... and up!
