Hi Coley, I am going to spend some time thinking about the options as it is a big expenditure if I go for the top end work. Thanks for the offer I appreciate it. Hi Restone, my weight Yoyos a bit but I am only slightly above weight, could do with losing a stone though so that would help Yep I am using as much power as there is throughout the mid range. Although I must stress, as said before, I am not interested in top end speed, acceleration is what floats my boat. Obviously not going to say too much on a public forum, but I am pretty happy and confident to twist the throttle lol that is the least of my concerns. I am sure even an old dog like me could learn some new tricks, but I have no issues with the riding side and if tuition enabled me to ride faster than I do I would not want to lol, that would be too scary and a tad dangerous
I might be wrong but as I understand it power is how often and prolonged the force of the engine propels your bike down the road. Torque is the force wth which it does it. A grose over symplification that equates to power = revs x torque. ( probably put in a completely arse about face way.....sorry) what I mean is??? is acceleration more or at least equally related to torque than top end power i.e revs and gas flow. Yes power plays a more important role as the revs climb. So would increasing torque acheive your acceleration goals. My old push rod engined buell with its monster torque and short gearing is quicker to 90 than my blade which has loads more power. I just find the whole subject of this thread fascinating........but then that is I guess why we like fast bikes and what makes them faster.
Restone, not sure on all the technical stuff but from my own experience, my previous bikes with high torque figures have had excellent acceleration even though they may not have had great top end speeds. My old Brutale had exceptionally rapid acceleration, but that only went to about 140 mph if you could stand the wind blast. As far as I know (which is not a lot) top end work gives better midrange with not much gain on horsepower whilst going down the big bore route gives higher top speed but can affect midrange. I am sure someone with a better knowledge will correct me as I am a layman. Power to weight ratio and rotational mass all play a part too. Love my Blade and I have spent a lot getting it to handle well and it does, it is now the best handling bike I have ever owned. I love the looks, the colour, the reliability and smoothness of the engine and the throttle is so smooth, I would just like that bigger rush when you open it up. Quickshifter will help I am sure as people who I respect rate them.
My biggest increase to my lap times by far were refreshing the brakes with braided lines and new pads. Literally took 4secs off my lap time which surprised me. Mate all of the above is 1000's of pounds and just for a few hp here and there so unlike cars and highly unworth it for the gains achieved. I really think Arthur is right, a QS with mapped ignition module will give you up to 5hp extra top end power for only 400quid. Hp per pound that is by far the best value increase and I'd like to think I can scream up the gears without the clutch but trust met pants were pulled down by the same bike with QS
Here's a lesson on how to create a light fast bike! Sorry, it's an 08 though Petar's track (light) bike : Honda CBR 1000RR Motorcycle Forums: 1000RR.net
Navvy, I agree totally about the brakes, upgrading mine has enabled me to ride quite a bit faster, one of my top three mods even though I had to get the suspension re-done afterwards to deal with my improved braking lol. Arthur is always right mate, that is why I trust him and that is why I will go down the QS route in the spring. Bang for buck it seems the best way and as you say it's not big money. I don't mind spending money on the bike IF it improves performance to a noticeable level. If I traded the old girl in I would be paying about £7 K extra for a bike that would not be set up for my riding needs and I would end up spending another 7K getting it there. Upgrading can be cheaper, but you have to keep the bike to get the benefits and understand you will not get your money back IMO. Power wise there is not 7 K's worth of difference between my modded bike and a new one, besides, they don't even have the exhaust under the seat I have already spent a stupid amount of money on my bike and knew it would not be be recoverable, but then it doesn't matter cos it is my passion/hobby and I just love to have a bike that is just how I want it......well almost lol. Don't drink/smoke or play around (anymore) so have to spend it on something. I do not think many of us are particularly 'sensible' when it comes to bikes in many regards. I am pretty sure that even if I had a MotoGP bike I would still want to mod it. Must remember to make an appointment to see the Doctor about my OCD.
What gains would head gasket and trumpets get? Head gasket thickness would adjust compression ratio, thinner is higher. trumpets vary length of inlet tract and position of peak power/torque in rev range. Also how hard is cam timing to do? Easy if you know how to do it and have a degree wheel and DTI?feeler gauges Thirdly is gas flowed head a benifit? Yes a great benefit, if all other mods completed. Should they all be done together or can u do them separate with a decent gain? All added up to increased power at major cost and only at top rpm. Thanks. Here to help.
Well mine has 176 bhp and 84 torques (as our J.Clarkson calls em) and its spread out far longer than standard Some of that is down to the trumpets and filter and exhaust , and PC V , and custom map
A blade with HRC head made 4hp more than mine on the same dyno.... IMO it would be much more cost effective to buy a more powerful bike
Thanks boys. I think il stick with fitting bazzaz and getting a decent map.... Tack electronics. And wait if it blows up or gearbox goes then I might do some tuning if the engines coming out anyway. Hard choice what to do really as it's sounds u got to do it all How good are those mwr filters ? They look good !

It's not hard to uninstall a head to porting it and working on compression..... A good head porting with a raise of compression, by milled the cylinder block ( to tighten the squish ) and the head to bump comp, give very good results. With 2 hrc gasket( 100£) , reprofiled cams ( 300£), labour with a friend ( two packs of beers ) and a good mapping ( 200£) i bump for 157 to 170 at the wheel, with gain everywhere. On every way, don't wait to gain 40hp of a motor job, a good engine tuning it's expensive but very funny to drive . It's not about making the best lap time on the track like i can see in a post, it's the roots of the motorcycle, tuning his bike and enjoy the results, just for fun . But even if France, i see this passion of the bike is lost...... sorry to see that. If you want to make a big engine, go for it, don't ask you if you ll gain 1s on a lap time, we don't give a shit of that preoccupation , just do it and enjoy. every day i rode a bike with HC piston, cams, gasket, cnc port head, Ohlins full, Beringer full and all my day are very fun and i enjoy them.
Bang on that, who cares for a sec here or there, do it for the love of the thing, do it for the smiles, so what if you ride to the cafe, I say do what makes you happy, once you ride powerful light weight bikes nothing else standard feels quite the same. More power + lighter = win win.
Sadly I can't do any of the real work myself so it puts it out of my budget! But sounds great when you have a friend in the know
Mmm I fancy some Defiantely. Do u do it Arthur plz ? But I am after one second hahaha or three! I don't ride on the road anymore only race
