Period correct exhaust for 1995 M900?

[ducpainter]

My guess is it will run fine with the stock jetting...maybe a little lean. That said, other than being blingy, you won't see any advantages from the system without tuning.

[Howie]

With the spaghetti it will be lean and loud.

+1 size for main jets was recommended IIRC.

Thanks for the info guys.  I'm into the bling for sure...

[Malloy]

Getting closer!

Oooh, fancy.

[Howie]

Really nice!

[Malloy]

Thanks guys! 

Do you think a DynoJet Stage 2 jet kit will do the trick? 

[Howie]

Hard to say.  The big restriction in the stock exhaust is the crossover, mufflers not so much.  Stage 2 (I think) will get you close enough to be able to ride the bike without much oh a problem.

I think the bigger jets in the stage 2 kit suit open airboxes and pod filters . May as well run an open airbox, K&N or BCM filter and then the stage 2 kit. I think for pipes only and a stock airbox you could use a stage 1kit and use the larger jets in the kit. Or get the stage 2 kit and use the smaller jets in it.
If you have the budget, buy some Keihin FCR flatslide carbs instead of the jet kit . The oem carbs are a pretty bad choice for that motor imo. It's a pity, as the motor is misrepresented by the carburation.

Fun to spend other people's money, eh?

I agree with Koko about the jet kits. You don't need stage 2 unless you open the airbox.

If you decide to swap to Keihins, be prepared to lose the starting circuit, and learn a whole new starting procedure. I have flatslides on my Monster, thanks kids, and since putting them on it's a PITA to start. That said, it's sweet to ride.

[koko64]

Vicarious pleasure.
Pricey though. Powerbarn sell them new for the same price for used out of Japan.

Just rebuilt oem carbs for a mates DB4 . Jets, needles, diaphragms, road testing, disassembly and reassembly all add up for sure. He's saving for FCRs.

These are used and still require the purchase of airbox or pod filter adaptors. There were four or five pairs I was watching but someone just bought most of them.

Mikuni option from Kamna

Hey Guys,

Thanks for the info.  I'm now tempted by the Power Barn kit...
