The fun would be found in your wallet. Getting that engine to produce any more real power would cost a mint and may make it less reliable. Lose the pods and Techlusion gimmick. Cut the airbox and put it back in there with a K&N, then flash the ECU to DP spec. Nothing works as well as a DP chip.

After that perhaps lighten your stock flywheel and get the heads lightly ported but not polished. Then get some lightweight wheels and declare victory. If you look at increasing your power to weight ratio as an exercise in both mild engine work and lightening the chassis, you may not have to go so far either way to satisfy yourself.

Spending a shit-ton on an 800cc wet clutch engine is not the way I would play it. I like the engine and know firsthand how hardy it is but you won't get your money's worth from doing heavy engine mods on it.

QFT.

The bike is plenty powerful as is. Focus your energy and money on getting more comfortable on the bike and learning how to use the power it has. Besides, if you kill ANOTHER Monster we're going to have to revoke your Duc card. There's a lot more performance there to use, learn how to extract it.
Every time I meet a new group of your friends that understand you and your weird sense of humor I'm a little more amazed that there are other people in the world like you that lived through childhood - My loving girlfriend

I had to look up QFT, never heard that expression before. 

I like my Monster Card.  As long as no more random BMWs or soccer driving Rover's forget how to park or drive, I should be ok.  :'(  [bang] I'm just wildly curious as to what it will take to get the most out of the engine.  Don't plan on doing the work tomorrow or this winter, just interested in what it would take.

I'll be dong some porting and lightening of the engine over the winter months as well.

I've been eyeing the Pistal High Compression kit, but have not decided if that's worth the hassle.

The chassis needs a lot of work to be able to exploit power increases.

Does anyone know if the 800 crank/rods will work in a 696 case?

The 696/796 share same heads, case, and bore, but 796 has a longer stroke. The 800/796 stroke is the same...

I was wanting to place an 800 crank/rods into 696 engine to basically make it a 796.

Anyone know if this will work?

If so, anyone have an 800 bottom end for sale?

cross reference part numbers on the pistons and rods and maybe even the cylinders.
there is a 4.4mm difference in deck height. not sure if it's in the cyl, rod or piston or maybe even the head.

If you really want to know what it takes to get Monster power out of the 800 just ask stopintime. He knows. He got close to 100hp at the rear wheel with heavy Kaemna mods :o

However it seems he was too embarrassed to divulge how much he spent. Must have been an assload. As in you could probably upgrade to a Streetfighter S for what he spent on the engine. It's more worthwhile for him however since motorcycles in general are much more expensive in Norway.

For my part, if the engine was running well I'd just lighten the chassis as far as I could within reason. It's all about power to weight. If you were to just get rid of the stock boat anchor wheels you would probably be amazed at the difference.

Just out of curiosity- how much do the stock wheels weigh vs. BST.  No way am I dropping $3K only to have them swallowed by a DC pothole, just very curious...

oh you're safe them... I think 2700 ;)

There's a thread in here somewhere with stock wheel weights, they are pretty hefty.  I don't know the weight diffs, but shouldn't be hard to find, its a huge difference though.  I rode a TLS with dymag carbon wheels and it was a huge difference from my TLS with stock wheels.  I don't think the monster's stockers are starting out much lighter than the TLS stockers, if any.

Another mod  I'd love to try on the monster would be a high end monoblock 4-pad caliper with a single 330mm rotor.  I'm pretty sure it'd have tons of power and enough heat-disappating ability that it'd live a reasonably long life given the monster's relatively megar power and low top speeds.  Loosing a rotor and caliper would be decent chunk of weight loss.

that's a cool idea.

Stock rear wheel 5.7 kg (12.7 lbs)

BST rear wheel 2.4 kg

Even though the price is ridiculous, it's a very exciting mod  [Dolph]
Compared to engine mods, BSTs are better cost/value.

Power improvement within reasonable 'investments'.... in my opinion.... open exhaust, DP ECU, fine degreeing cams, PCIII with a Ducati experienced tuner and a Dyno day. Somewhere around 8-10 bhp and 10-12 Nm after this list (compared to stock 800)

You'd have to be married to (only) your bike, stupid, crazy and bored to do what I did to my engine and bike.
It's very very very fun to ride and evokes a lot of interest, but nowhere near sensible.

I'm doing pretty much that on a '98 M750.

You're supposed to avoid the potholes. At least that's what I always did. Situational awareness. For example; you see a nasty, deep, sharp-edged hole in the street ahead of you. What you should do in this situation is navigate your motorcycle in such a way that your tires don't roll into or over the hole. I don't believe in unavoidable potholes. They're only unavoidable if the rider is too busy watching his reflection in storefronts to pay attention to the road surface ahead. [thumbsup] Or chicks with big titties

Potholes can swallow stock cast rims up just as easily as fancy carbon ones. It's just not as sad when it happens.

And FYI, it's a myth that BST carbon wheels are fragile. Total myth. They are highly engineered items and quite strong and resilient indeed. I wouldn't hesitate myself.

I would also do this if I ever got another Monster (an M800 would be my preference). This combined with better wheels would be a huge difference. The only problem I can see is getting a nice front wheel that is only set-up for one rotor...otherwise you'd have to figure out how to make the side without a rotor look pretty despite the mounting locations.  :-\
