Bandit 150rwbhp Enough?

[BikeJake]

I am starting to put the bits together for my project. Exhaust, pistons, engineering, cams etc.... 

I am aiming for 150 at the wheel, Roger Upperton said the collection of bits I'm assembling should do the trick... 

Fair old wallop of dosh to rely on my spannering skills, but I've rebuilt a good few jap fours over the years so I don't forsee an issue with that. 

I'm just worried that... I'll always feel is lacking.. So used to Gixxers and late Fireblades, I love thr riding style and the feel of the bike is reminiscent of my old bikes I had when a younger man.. 

Had anyone built anything like this and been satisfied with the grunt?

A M8 who is the wrong side of 60 and doesn't get to ride much, built a '96 Blandit, 1216 kit, GSXR lightened crank and clutch, reworked head, std valves & cams, RS36's and a Ackro Carbon system and it makes 152whp. He rode it last week after messing with the throttle return and apparently it was back to what it used to be, lifting the front on demand and quick enough that is starting to show deficiencies in the Hyperpro front and the Ohlins equipped aftermarket back end. He was 'cheshire cat' type grinning as he told me about it LOL! A Blandit is never going to be a GSXR or a Blade but they can be equally entertaining from his experience I think?

[coombehouse]

Bear in mind that a 1st generation gsxr1000 makes 146rwhp & modern super nakeds are around 160ish & they handle & stop better than any bandit.

150rwhp will be plenty to contend with. 

[dupersunc]

They aren't as refined as a modern il4 1000cc motor but have a flatter torque curve. 150rwhp will be an event on a bandit, fast and visceral, induction noise without an airbox makes everything feel more violent than  170bhp of modern motorcycle.

Yes... as long as you fix the supenders as well

149.8RWHP

First thing I did matey. say what now!? shock, pregressive front spring and braced rear arm coming next. All before I start the engine...

Probably ride it and make a decision on upsidedowners and uprated calipers. 

Mind if I ask how your CVs get on wjtb the filters and what filters they are? 

CVs and airbox removal haven't gone so well for me lol

[Bow]

1216 high comp pistons,  SUZ1 cams, dynojetted stock carbs, decent headers and can,15/47 gearing.  148rwhp.

you don’t have to spend a fortune to get them going well.

plenty fast enough, grin inducing coming out of bends and junctions,  upgrade fork internals, rear shock, and look after your brakes.  Good fun on the road, even with the flexible frame .

When I first built the engine 12 years ago, I had 40 mm mikky roonies on it and it made 152 after setting up on a dyno, but they were a pain, tick over was never stable and they were always going out of balance!!

I fitted the standard carbs with Ramair filters And Holeshot racing carb kit from Dale Walker, they have been spot on ever since,

all I’ve done to the engine since are oil changes, clean carbs a couple of times, tappets and a new clutch..

Still pulls like a train and able to hold its own on track days

That is promising 

Which big bore did you use? 

[fatblokeonbandit]

That one had brand new J&E pistons, the engine in my teapot with the same output was a second hand wiesco set.

 

A bit snug, 1216 in a 750

Is thst breather filter all you used on the crankcase, no need for a one way valve? 

[fatblokeonbandit]

its a catch can with filter on top comes from the breather on top of rockerbox..

 

 

i have similar on my b12..

 

and a big one on my Moto martin, really cheap from chinaland..

Air has to move in and out of the crankcase unless you are using a dry sump system and then you vent the holding tank - no one way valves!

Doesn't that breather go into the intake?

What if it does?

It'll be atmospheric side of the butterflies so effectively, in free air.

Only done by OEM's for emissions purposes.

Just read this @fatblokeonbandit

[Tony Nitrous]

168hp on a somewhat optimistic dyno.

Carbon can, air filter, upgraded clutch springs and new Suzuki plates… and 60hp worth of nitrous! Battery in tail with an extension made from 2 car starter motor leads, fuel pump and solenoids in the battery box, foggers in the inlets, micro switch on the carbs so it only triggered on full throttle when armed and fired, switch on the bars that turned the horn button into the nitrous bottle, 2.5lb bottle mounted at the correct angle and within reach.

I went through a LOT of gas in short bursts.

OEM and untouched factory tyres, brakes, suspension etc kept life quite entertaining.

Most Modern 1000s have in excess of 170bhp the BMW being over 200 reputedly out the box...

Yes the have fantastic handling and brakes  but you can still tie yourself in knots just the same as on a 145Bhp dinosaur

And you have ride a dinosaur, instead of just being a board a fast well handling modern bike 

[bluedog59]

The problem with modern sportsbikes is they so far ahead of 99% of their riders that it's very easy to get a long way into a dangerous situation without realising it and no amount of ABS, traction control or whatever is going to save you at that point. 

Then again, most of them have got no idea anyway. They come flying past on the straight, brake waaaaay too early then potter round the corner on a crap line while hanging off like a demented chimp and thinking they could beat that Valentino Marquez bloke.

[yantosh]

my K4 engine has 150bhp, does me fine 

[wraith]

I've always said to much is never enough  but these days I still say the same but don't turn the throttle as much
