M1100Evo Exhaust Valve

[Uksurfer]

I have just put on a New Rage Cycle tail tidy and I have removed the under seat servo, I have plugged in the Duciee eliminator, has anybody got any pictures on how best to remove the actual flapper valve in the exhaust system
Thanks

My method of drilling out the screws on the flapper valve was the easier way to without risking damage the exhaust. So far I have had no issues with the work but welding the openings on both sides is required.

You already have a DUC.EE but if you plan of doing aggressive modifications to fueling in the future consider that the ECU reflash can eliminate the need for the Duc.ee as well.

Yes, I'm going to tackle the exhaust side of things this weekend, the tail tidy is fitted and looks good, I've managed to put all the wires into the space the servo was taking up. I've mounted the number plate under the tail light, I'm not sure whether to mount it down nearer the shock?

I've also just fitted an Ohlins shock

Tidy .
Please report on the Ohlins Shock performance.

I have the same DU 737 ohlins shock on my 1100 EVO. In all honesty, its a moderate difference in performance compared to the sachs shock. Its really a budget upgrade to the bike. Don't expect a revelation in performance.

I'm not saying its horrible. Just that you get a good street level performance on the bike. You also only get preload/rebound adjustability on the unit. Having that compression and rebound circuit separate helps with fine tuning. Right now both are adjusted together.

If you're looking for top end performance, Penske is a better bet. Also the Penske has a built in ride height adjustment. This is a big deal for the evo. I custom shimmed the back clevis 4mm with two washers (the most you can safely do IMO) and noticed a huge difference in handling. Yes you can lower the front end similarly but I a firm believer in not losing ground clearance at the expense of improved handling.

BTW Keep the plate up. If you ride in the rain, the license plate will act as a splash guard keeping more water off your back.

The shock I bought was more of an impulse buy 2nd hand, I believe from the seller it's set up for my weight, I'll try it and then see it it need adjusting. I know what you mean about the licence plate, with the evotech tail tidy I got a wet back and seat, so I imagine this will be worse 🏍 I found a new pair of heated grips in the garage that I won in a raffle last year, so I'm tempted to fit those while it's in the garage..

What is the code on your spring? I bought mine second hand as well and had to figure out the spring rate info. The last few numbers on the spring identify the spring rate. The stock for the DI 737 shock is a 115 N/M. This covers a range of weight from around 150 - 180.

The problem with the monster 1100/696/796 shock from ohlins is that the spring rates for that specific size spring are not available in a variety of sizes. It goes straight from 115 NM to 130 NM without an intermediate.

On the lighter side they have more options. 110 NM, 95 NM ,etc. If you weigh around 160, you're going to be fine with stock. I tend to track my bikeas well so I went with something a bit stiffer at 130NM. I had to back out the preload adjuster to compensate for the rider sag of 30mm but I weigh 195 with full leathers sO i was borderline with the 115NM spring.

Ideally if you weight 180lb. You would want something around the range of 120 NM. You would have to go to a custom spring from eibach to get it dialed in perfect.

I'm not sure on the number, I'll have a look next time I'm in the garage and report back
